IV.DEFINITIONS AND INTERPRETATIONS OF FOOD RELATED TERMS
In the following list of definitions of food-related words and
phrases, some of the items relate to the requirements under UK and/or
European laws, regulations or Codes of Practice. In the near future
anther list will be given referring to the requirements under US laws
and regulations, and, in time, those of other countries.
Any questions or comments about these definitions and
interpretations should be directed to: <[EMAIL PROTECTED]
INTRODUCTION
In 1987, the Technical and Legislative Committee (TLC) of the
Institute of Food Science & Technology, conscious that many
descriptions of, or claims about, foods were made using ill-defined
terms which were potentially misleading, set out to remedy that
situation. Making use both of published material and the expertise of
the Committee, it prepared and issued objective "definitions" for
certain key words, a few of which were not considered potentially
confusing but merely useful to include.
The intention was not strict definitions in the dictionary
sense. Some were accounts or interpretations of the limitations
within which the use of a particular term was justified. Moreover,
the intention was not to produce a comprehensive dictionary of
food-related terms, but rather a guide to food scientists and
technologists, and others professionally concerned with descriptions
of foods, particularly in labelling and advertising. In 1989, the
list was expanded and published in Food Science & Technology Today 3
(2), 128-9.
In the period since that publication, some of those terms have
been "officially" defined in legislation, official guidelines or
Codes of Practice - and it is gratifying to note the extent to which
these follow the lines of the definitions in the 1989 document. In
the same period, members of IFST and of the Association of Public
Analysts have suggested additional terms that are in common usage but
are ill-defined or sometimes misused. Accordingly, the two
professional bodies have decided to produce jointly an updated list.
The list given here includes some terms that were in the 1989
list (in some cases modified or updated); and some terms that have
been defined in the interim in legislation or in codes or guides.
Many of the terms listed here have wider connotations in relation to
which they may be defined or interpreted; but here it is only the
food-related usage that is addressed.
We draw attention to the category Marketing Terms at the end of
this document, in which have been listed a number of terms often used
without real meaning in relation to manufactured food products.
As before, it is hoped that the use, by professionals, of these
definitions and interpretations will help to minimise confusion and
misleading use of the terms. With any such exercise, some readers
will have differing views on individual items, or on the desirability
of including other terms. IFST and APA will be glad to receive
constructive comments from members, for consideration when this
document is next revised and updated.
Finally, it is pointed out that definitions other than those
derived from EU or UK legislation, and all interpretations expressed
here, are opinion, albeit opinion based on the views of the experts
involved in their compilation. The information in this document may
not be taken as binding on Public Analysts or enforcement authorities,
and, in the event of dispute, only the courts can decide.

Biopolymer
A compound consisting of repeating units of a single
biologically produced molecule, either straight chain or branched,
e.g. amylose, amylopectin and cellulose.
Biotechnology
The application of biological science to the production,
modification or processing of materials. It encompasses
long-established activities such as traditional plant and animal
breeding, brewing, bread-making and effluent treatment, and the more
modern techniques of genetic modification and the use of fermentation
technology for the production of some novel protein foods. Though
meal preparation is arguably a form of biotechnology, it is already
covered in other newsgroups, such as rec.cooking.* hierarchy.
Boiled
Having been cooked in boiling water (or, by extension, by
steaming, as in 'boil-in-the-bag').
Chilled food
Perishable food which, to extend the time during which it
remains wholesome, is kept within a specified range of temperature
usually between 2 and 8 degC.
Chilled food chain
The sequence of temperature controlled operations after initial
harvesting, and including chilled transport, cooling during and after
production, chilled storage, distribution and retailing, through to
domestic storage until preparation for final consumption.
Comercial Sterility
A sterile product is one free from viable microorganisms, i.e.
those capable of reproducing under optimum conditions for growth.
'Commercial sterility' is a term commonly used in the canning
industry meaning the condition achieved by the application of heat
sufficient to render the processed product free from viable
microorganisms (including those of known public health significance),
capable of growing in the food under normal non-refrigerated
temperatures at which the food is likely to be held during
distribution and storage.
Convenience food
A manufactured product requiring little or no preparation (other
than heating, diluting or dissolving in water, where appropriate)
before consumption.
Cooked
Having been subjected to a heating process sufficient to render
the food suitable for consumption.
Critical control point
Any point in a specific food system where loss of control may
result in an unacceptable risk.
Crude fibre
The structural component of the plant cell wall being the
residue obtained after consecutive acid and alkali digestion of a
food or food material. Crude fibre is determined for nutritional
declarations on animal feeding stuffs and also for defining brown
bread in the Bread and Flour Regulations 1984.
Dairy
When used as a descriptive term for food, refers exclusively to
milk and milk products. In the EU its use is legally governed by
Council Regulation 1898/87 on the Protection of Designations used in
the marketing of Milk and Milk Products, as supplemented by
Commission Decision 888/566/EEC. Help in interpreting some of these
provisions was given by a MAFF Guidance Note (November 1989). The
Council Regulation was subsequently implemented by the UK in the Milk
and Milk Products (Protection of Designations) Regulations 1990.
Dehydrated (food)
Food or food products from which all but a small percentage of
the water has been removed under controlled conditions.
Designer food(s)
See Functional Foods and Marketing Terms.
Disinfection
The application of effective chemical or physical agents or
processes to a cleaned surface or to a water supply to reduce the
number of microorganisms to a level consistent with good hygiene
practice.
Dietary fibre
In scientific terms, dietary fibre is a mixture of components
derived from plant cell wall material and non-structural
polysaccharides, as well as non-starch polysaccharides added to
foods. It includes non-digestible polysaccharides such as cellulose,
hemicelluloses, gums, pectins, mucilages and lignin. From a nutrition
point of view, some authorities also include 'resistant starch' (i.e.
starch that is resistant to enzymic degradation, usually as a result
of processing).
Currently, there is no universally accepted method for
determination of dietary fibre. For some years the UK Ministry of
Agriculture, Fisheries and Food (MAFF) has adopted the definition,
for the purposes of label declaration, that dietary fibre is
non-starch polysaccharides as determined by the Englyst method; but
in Guidelines issued in March 1994, MAFF indicated that analysts may
use any other methods which give similar results. The Englyst method
excludes resistant starch. Most EU countries and the USA use the AOAC
Prosky method. This method includes resistant starch and the value
for dietary fibre obtained is therefore invariably higher than that
by the Englyst method. It should be noted, however, that no
recognised analytical method fully corresponds to biological
performance.
Emulsion
A term descriptive of a food or food material consisting of a
stable blend of two or more otherwise immiscible liquids, usually an
oil and an aqueous phase, achieved by appropriate physical means and
usually with the incorporation of emulsifying and stabilising agents.
Enriched
See "fortified foods"
Fast Food
This term is not descriptive of food per se, but categorises a
type of catering outlet, providing, within seconds of being ordered,
counter delivery of freshly-prepared food items capable of being
eaten without cutlery. This delivery is mainly dependent on
scheduling based on accurate anticipation of fluctuating demand, a
production system and staff capable of keeping pace with it, and
sufficient counter servers to minimise queuing. Because some foods
(e.g. burgers) have lent themselves more readily to this type of
operation, the term has come to be applied to them too.
Fermentation
The process of chemical change in animal or plant material,
catalysed by enzymes of biological origin. It may be intended, as in
brewing of beer or vinegar, or unintended and undesirable, as in food
spoilage.
Fermented (food)
Food material having been subjected to fermentation
Fibre
Sometimes used synonymously with "dietary fibre" including in
European and UK nutrition labelling legislation
Flavour/flavoured
The term 'flavour' may have reference to sensory quality of a
food as perceived by a combination of smell and taste. When used as a
noun, 'flavour', for which the legally correct term is 'flavouring',
is defined in the UK Flavouring in Food Regulations 1992 as a
material used to impart odour, taste or both to a food.
Food
The Codex Alimentarius defines 'Food' as "any substance, whether
processed, semi processed or raw, which is intended for human
consumption and includes drink, chewing gum and any substance which
has been used in the manufacture, preparation or treatment of food,
but does not include cosmetics or tobacco or substances only used as
drugs".
In the UK Food Safety Act 1990, 'food' is defined as including
drink, food ingredients, food additives, chewing gum and similar
substances, but excluding live animals or live fish (unless consumed
alive), animal feeds, controlled drugs and medicinal products bearing
a product licence. This definition states what 'food' includes and
excludes (similarly to the latter part of the Codex definition) but
it is deficient in failing to define what food is.
Food hygiene
All environmental factors, practices, processes and precautions
involved in protecting food from contamination by any agency, and
preventing any organism present from multiplying to an extent that
would expose consumers to risk or result in premature spoilage or
decomposition of food.
Fortified (food)
Three separate circumstances may be defined: Restored, enriched,
and fortified foods, as described here:
Restore
the addition of nutrients to foods in order to restore the
level of those nutrients that were originally present, but have
been destroyed or lost in processing.
Enrich
The addition to a food of one or more nutrients which were
already present in that food in lower than desirable amounts.
Fortify
The addition to a food of significant quantities of a
nutrient that was not originally present in that food or was
present only in nutritionally insignificant amount.
Free from ....
For food to be described as 'free from X' (or by terms having a
similar import) the food, at the point of sale, must be either free from
X when tested by a standard reference method of analysis or it must
contain no more than a specified maximum of X.
Free from added ....
If a food in its original state contains X, it may be described as
'free from added X' (or by terms having a similar import) only if no X
has been introduced, directly or indirectly, via any ingredient or
during production, manufacture, processing, packaging, storage,
distribution or point of sale. MAFF Guidelines (1993) specify that 'no
added sugar' means that no sugars, or foods composed mainly of sugars,
should be added to a food or any of its ingredients; and that 'no added
salt' means that no salt or sodium compounds should be added to the food
or to any of its ingredients.
It should be noted, however, that in the instance of a food which
strictly complies with the foregoing but itself has a high sugar content
(for example date paste) the description 'no added sugar', though true,
could be held to be misleading (Section 3(2) of the Trade Descriptions
Act 1968).
Fresh
The condition of a short shelf-life perishable unprocessed food
prior to perceptible evidence of physical, chemical or microbiological
change. Fresh is normally applied to unprocessed foods e.g. fresh eggs,
fresh meat, showing that they are in their original state. It is also
used in apparently contradictory terms, e.g. fresh pasteurised cream to
distinguish it from more highly processed sterilised cream.
Functional
Fulfilling a specific physical, chemical or biological function.
Functional food(s)
All foods are functional, and to term some (as distinct from
others) as 'functional' is illogical. The term is one of the
marketing-coined names (others are 'neutraceuticals' and 'designer
foods') to categorise foods which are considered or claimed to offer
specific health benefits while avoiding the requirement to be licensed
medicines (See Marketing terms, below).
Genetic modification
see FAQ in section V (including within-species and
trans-species) Part 2, Q 7, 8, and 9
Genetically modified-See FAQ same sections as above
Genuine
'Genuine' in connection with foods means an authentic type or
source. It serves to distinguish ingredients which might otherwise be
synthetic (e.g. 'vanilla ice cream, made with genuine vanilla') or it
may establish the origin or type of a food (e.g. genuine Manzanilla
olives, genuine Italian olive oil).
GMP
'Good manufacturing practice' (GMP) is that part of a food control
operation aimed at ensuring that products are consistently manufactured
to a specified quality appropriate to their intended use. It thus has
two complementary and interacting components; the manufacturing
operation itself and the control system and procedures. Reference should
be made to the IFST publication 'Food and Drink - Good Manufacturing
Practice: A Guide to its Responsible Management'. (3rd Edition, 1991).
HACCP
Hazard Analysis Critical Control Point (HACCP) is a preventive
system of food control. It involves examining and analysing every stage
of a food-related operation to identify and assess hazards (q.v., below);
determining the 'critical control points' (q.v., above) at which action
is required to control the identified hazards; establishing the critical
limits that must be met at, and procedures to monitor, each critical
control point; establishing corrective procedures when a deviation is
identified by monitoring; documentation of the HACCP plan and
verification procedures to establish that it is working correctly.
HAZOP
Hazard and Operability Studies (HAZOP) is a systematic structured
approach to questioning the sequential stages of a proposed operation in
order to optimise the efficiency and the management of risk. Thus, the
application of HAZOP to the design of a proposed food-related operation,
should result in a system in which as many critical control points as
possible have been eliminated, making the subsequent application of
HACCP during subsequent operations much easier to carry out.
Hazard
Any intrinsic property of a system, operation, material or
situation that could, in certain circumstances, lead to an adverse
consequence. In food terms, this particularly refers to an adverse
consequence (health risk or loss by spoilage) to the consumer.
Health food
This is essentially a marketing term, the meaning of which has
never been clear. There is no legal basis and no evident objective
justification for the term, which implies a superiority over foods not
so described. So-called health foods fall into four main categories,
namely
1) products in respect of which there is adequate scientific
substantiation for the specific permissible nutrition and/or health
claims made, and which are labelled in accordance with relevant
legislation;
2) those in respect of which there is 'folklore' and some
scientific evidence for the claims, but falling short of substantiation;
3) those making claims for which there is little or no scientific
evidence;
4) other products that are frequently sold in health food shops
e.g. 'wholefoods' (q.v.).
It should be noted that some products in categories 2 and 3 have
given rise to concerns about their safety, which, in certain cases, have
led to prohibition.
Hermetically sealed container
Strictly, an 'hermetically sealed container' is one that is sealed
so as to be air-tight. Commercially sterile food products may be packed
in non-metallic containers that are not completely air-tight. In the
latter context, an 'hermetically sealed container' has been defined as
one that is designed and intended to be secure against entry of
microorganisms.
High in .....
Complying either with a declared or, where existing, a
legally-specified minimum, or a legally-specified percentage increase
compared with a product not making a "high in" claim for the parameters
involved."
Higher in (increased) .....
Complying either with a declared or, where existing, a
legally-specified percentage increase compared with a product not making
such a claim, for the parameter involved.
Home made
This term has no defined meaning but it implies that a food has
been prepared on a small scale, either on domestic premises or premises
not associated with large scale manufacture.
Improved
Primarily a marketing term, and sometimes used in conjunction with
'new', it may cover a wide variety of circumstances, including minor
cosmetic changes, cost-cutting changes, and formulation changes to make
the product more acceptable to purchasers. It is the latter case that
most properly justifies the use of the term.
Instant
This term is strictly justified only in the cases of dry powders or
mixes which rehydrate instantly, i.e. in a matter of a few seconds (e.g.
instant coffee, instant tea) and should be reserved for such speedy
action. By extension, however, the term has sometimes been misused by
applying it to dry mix products which rehydrate faster than some others
but still take a few minutes rather than a few seconds. For the latter,
a term such as 'rapid' would be more appropriate.
Irradiated
Having been subjected to ionising radiation.
Isotonic
A term applied to a liquid product, e.g. a drink, having osmotic
properties approximating to those of blood serum, i.e. 280 milli-
osmoles per kg.
Light/Lite
These terms are used to signify a lower energy or lower fat version
of a particular food, [and therefore should comply with conditions
applying to a reduced .... claim. (see Reduced .......)]. That would
imply at least 25% reduction of the norm, but some opinion holds that it
should mean at least 50% reduction.
Low calorie/low energy
A description which may be applied to foods which, when ready for
consumption, have an energy value no greater than 167 kJ (40 kcal) per
100 g (for the purposes of theUK Food Labelling Regulations 1984,
intense sweeteners and similar products are exempted from this limit).
Low in .....
Complying either with a declared or, where existing, a
legally-specified maximum or a legally-specified percentage reduction
compared with a product not making a 'low in' claim for the parameters
involved.
Manufacture
The complete cycle of production of a food product from the
acquisition of all materials, through all stages of subsequent
processing, packaging and storage, to the despatch of the finished
product.
Meat
'Meat' means the flesh, including fat and the skin, rind, gristle
and sinew in amounts naturally associated with the flesh, of any animal
or bird which is normally used for human consumption, but including only
those parts of the carcase listed in Part I of Schedule 2 of the UK Meat
Products and Spreadable Fish Products Regulations 1984.
Natural
The extensive use of 'natural' in labelling and advertising arises
from a public misconception, that 'natural' necessarily means 'safe',
healthy', 'nutritious' (in contrast to its perceived opposites,
'unnatural', 'unsafe', 'chemical', 'processed', etc). The consequent
marketing view that 'natural' should be used wherever possible to
reassure those fearing adverse effects of 'unnatural' foods, resulted in
widespread indiscriminate use of 'natural' despite the efforts of food
scientists and technologists in industry and enforcement to restrict its
use to justifiable cases. Although based on a misconception of the
significance of 'natural', if some consumers wish to select foods which
are 'natural', they are entitled to information that is meaningful and
not misleading.
In 1989 MAFF published FAC guidelines on the detailed conditions
and circumstances in which the use of 'natural' or similar terms) was
justified. In summary these were (a) to describe single foods of a
traditional nature to which nothing has been added and which have been
subjected only to such processing as to render them suitable for human
consumption.; (b) to describe food ingredients obtained from recognised
food sources, and which meet the criteria in (a); (c) to describe
flavouring substances (but see 'natural flavouring', below) or permitted
food additives obtained from recognised food sources by appropriate
physical processes or traditional food preparation processes. The
reference in (a) to 'a traditional nature' was intended to exclude foods
such as mycoprotein which may be products of natural sources but were
not considered by FAC to accord with the public perception of 'natural'.
Compound food should not be described as 'natural' but could be
described as 'made from natural ingredients' if all of the ingredients
comply with (b) or (c). In the cases of foods not complying with the
above criteria, 'natural' or its derivatives should not be used in brand
or fancy names or incorporated in meaningless copy. Phrases such as
'naturally good', naturally better', etc should be avoided.
At the time IFST urged that the abuse of the term was such that
these conditions should be embodied in legislation, but Ministers
decided otherwise. Nevertheless, although these conditions do not have
de jure force of law, enforcement authorities and courts can use them as
yardsticks in assessing whether a particular usage is misleading; so to
that extent they have de facto legal force.
Natural flavouring
The UK Flavourings in Food (Amendment) Regulations 1994 now
provides a legal definition to supersede that provided in relation to
flavourings in the FAC Guidelines on the use of the word 'natural'. It
provides that a 'natural' flavouring may be obtained from vegetable or
animal material by enzymatic or microbiological methods as well as
physical ones; and that if the name of the flavouring refers to its
vegetable or animal origin, it can only be designated 'natural' if it is
derived wholly or mainly from the named vegetable or animal source.
Nature-Identical
a term applied to flavouring substances or mixtures thereof that
have been synthesised or isolated from aromatic raw materials but are
chemically identical with substances found in natural products used for
human consumption - in the US this is otherwise known as "Artificial
flavor".
New
Primarily a marketing term, and sometimes used in conjunction with
'improved', it may cover a wide variety of circumstances, ranging from a
minor formulation or packaging change from a previously marketed product,
through a product that is new to the manufacturer but very similar to
products already on the market, to a product that is really innovative.
How long can a product labelled 'New' continue to be so labelled? There
is no official answer, and it is extremely difficult to give one. This
is because a new product may be subjected to test marketing in a
particular part of the country, and then 'rolled out' progressively
until it reaches national distribution, perhaps taking up to two years
in doing so. A maximum of one year from national distribution seems a
reasonable limit.
Novel (food, process)
Food or food ingredients produced from raw material that has not
hitherto been used (or has been used only to a small extent) for human
consumption in the area of the world in question, or that is produced by
a new or extensively modified process not previously used in the
production of food. A question open to debate is "At what point does a
novel food (e.g. mycoprotein), having come on the market and being
fairly widely consumed, cease to be a novel food?"
Any person or company contemplating marketing in the UK a novel
food or one containing a novel ingredient should make a prior submission
to the Advisory Committee on Novel Foods and Processes (ACNFP).
Nutraceutical
See Functional food.
Organic
(See FAQ part 1, No. 20 for comparisons between organic and
other foods)
This term, like 'natural', has been used for marketing purposes, in
this case to reassure those who fear the use of 'chemicals' in
agriculture. In the past, the meaning of 'organic' was by no means clear,
and instances were found of so-called organic products containing
higher agricultural chemical residues than their non-organic
counterparts. If some consumers desire organic produce they are entitled
to know it complies with certain standards.
The Organic Products Regulations 1992 give effect to EU Council
Regulation EEC No 2091/91 on organic production of agricultural products
and foodstuffs. The use of the word 'organic' is restricted to
agricultural crops and livestock and products made from them, in
compliance with the detailed provisions of Annexes I, II and III of the
Council Regulation. The control body in the UK is Food From Britain,
carrying out its duties through the UK Register of Organic Food
Standards (UKROFS) which is based at the Food From Britain office.
Compound foods may be described as organic if at least 95% of the
ingredients (apart from added water) are of organic origin. If the
compound food contains less than 95% but more than 50% organic
ingredients, the food may not be described as organic but the organic
components may be identified as such in the list of ingredients.
Original
This adjective may be justified in respect of a well established
product, to distinguish it from subsequent variants marketed by the
manufacturer. Likewise it could be used in respect of a product which
was first in the marketplace to distinguish it from subsequent 'me-too'
imitations.
Probiotic
This term, as a noun or adjective, has previously been used to
refer to 'microorganisms and substances which contribute to the
intestinal microbial balance'. However, the inclusion of 'substances'
created the paradox that antibiotics could be probiotics if they were
specific enough to destroy harmful bacteria thereby restoring the
intestinal microbial balance. Accordingly, it is now suggested that
'probiotic' should be taken to refer to 'a live microbial preparation,
either as a food or animal feed, which can benefit the host through
restoring its intestinal microbial balance'.
The microorganisms most commonly involved as probiotics are the
Lactobacilli, Bifidobacteria, Streptococci and some yeasts and moulds.
Probiotic preparations may have one or a mixture of organisms of various
genera, species, sub-species or strains, and may take a variety of
physical forms.
There is conflicting evidence, and controversy, about the extent to
which colon flora can be influenced by oral administration of the
various microorganisms involved, at the levels found in conventional
foods.
Processed
Having been subjected to treatment designed to change one or more
of the properties (physical, chemical, microbiological, sensory) of
food.
Processing aid
In the UK Food Labelling Regulations 1984, 'processing aids' are
not separately defined; but the definition of 'additive' 'includes
processing aids insofar as they added to, or used in or on, food'. It
follows that a processing aid is an additive which facilitates
processing without significantly influencing the character or properties
of the finished product. Examples would be a tablet release agent used
to coat the inside of tablet moulds, or a spray used to allow bread to
be released from baking tins or trays. There are, however, anomalous
instances. For example, if an anti-caking agent is added to a powder
ingredient to facilitate its flow properties while being conveyed to a
mixer, where it is incorporated into a liquid product or a dough for
baking, the anti-caking agent is used solely as a processing aid, and
hence need not be declared. If however, that powder ingredient is
directly packed into containers for sale as such, or is incorporated in
a dry mix product, the anti-caking agent is not acting solely as a
processing aid and must be declared as an additive.
Pure
This word is used as a marketing term, and is usually applied to a
single ingredient with no additions, e.g. pure vegetable oil, pure
orange juice, whether in the form of a single ingredients food or when
used as a major ingredient of a compound food.
Quality
When applied meaningfully to the character of a food, 'quality' may
refer to (a) the degree or standard of excellence; or (b) the fitness
for purpose; or (c) the consistency of attainment of the specified
properties of the food. In the context of food control, it is meaning
(c) that applies.
The term is sometimes used in a meaningless marketing sense (e.g.
'X is a quality product').
Raw
In the earliest or primary state, after harvesting or slaughter,
not having been subjected to any treatment apart from cleaning, size
grading or size reduction, (e.g. diced raw vegetables, raw minced beef).
Some ingredients termed 'raw materials' may actually be 'raw'.
Often, however, one manufacturer's starting materials are other
manufacturers' finished products; and a more accurate description would
be 'starting materials'.
Real
A marketing term, used normally to emphasise the presence of an
authentic ingredient in a product, as distinct from a substitute (e.g.
biscuits with a real chocolate coating).
See also Genuine.
Re-formed
'Re-formed' meat is an artefact having the appearance of a cut,
joint, slice or portion of meat, formed by combining pieces of meat
which have undergone processes generally including tumbling or massaging
or specific alignment of fibres, with or without the addition of finely
comminuted meat and/or meat emulsion, and then forming in moulds or into
shapes. Codes of Practice exist for the labelling of cured meat products
and quick frozen meat products respectively, made from re-formed meats.
Reduced .....
Complying either with a declared or, where existing,
legally-specified percentage reduction compared with a product not
making a ""reduced" claim, for the parameter involved.
Restore
See Fortified (foods).
Rich in .....
See High in .....
Selected
Primarily a marketing term, implying superior quality. It should
not be used unless it can be substantiated that the product quality has
been enhanced by an actual selection process.
Sensory
Relating to the use of the sense organs. (Note the distinction from
'organoleptic' 'relating to an attribute of a product perceptible by the
sense organs')..
BS 5098 (identical with ISO 5492: 1992) entitled 'Sensory Analysis
Vocabulary' provides an extensive and authoritative set of definitions
of terms relating to sensory analysis.
Snack
A small quantity of food, eaten informally between, or in place of,
main meals.
Snackfood (Snack food)
A convenient food item specifically manufactured for use as a
snack.
Spoilage
Any perceivable change undergone by a food, through any cause, that
renders it unwholesome or unacceptable for use. Spoilage is usually the
result of enzyme or microbial action resulting, for example, in
lipolytic rancidity, putrefaction, fermentation, or mould growth; but
food can also spoil by other means, for example overlong storage,
non-enzymic browning, or exposure to air or light. In practice the term
is most frequently applied to categorising such deteriorative changes
(other than food infection or intoxication) when caused by
microorganisms.
Steak
'Steak' has, in the past, been taken to mean a cut or thick slice
from the beef animal. However, a judgement in the Court of Appeal in
1986 allowed a re-formed product to be called 'Chicken Breast Steaks
Flaked and Formed Chicken in a Crispy Crumb' on the grounds that the
description of the product, as a whole, was clear, accurate and not
misleading. This judgement, therefore, means that 'steak' can be used,
provided that it is properly qualified, as a generic term, probably in
relation to any animal, bird or fish normally used for human consumption,
and whether or not the meat has been re-formed.
Traditional
One way of defining 'traditional' in relation to foods and food
processes is to say it is the opposite of 'new' or 'modern' (cf. the
FAC's use of 'traditional' with the intention to exclude novel foods,
see 'natural', above). It can also be applied to a particular
characteristic of a food; for example 'traditional flavour', 'made in
the traditional way'. This leaves unresolved, however, the question "at
what point does yesterday's 'new' or 'modern' become today's
'traditional'?". One suspects that for each generation, 'traditional'
means anything up to and including the foods and methods of one's early
youth! For some, 'traditional' appears to mean rule-of-thumb craft-based
rather than based on science/technology.
Unadulterated
A food material containing no additions or contaminants foreign to
the normal product which otherwise would debase it or confer or disguise
inferior quality.
Wholefood
Any food which contains all its naturally occurring components,
(e.g. pulses, raw vegetables) and without the addition of other
substances. A wholefood can be a mixture of wholefoods.
Wholesomeness
'Wholesomeness' is a convenient single term which embodies a large
number of aspects and attributes of a food. In summary, a wholesome food
is one that satisfactorily meets the expectations of the segment of
consumers at which it is aimed; and that has been made, stored and
handled in compliance with any relevant legislative standards and with
all of the principles of good manufacturing practice.
Full consideration of these characteristics is given in IFST
Professional Conduct Guideline 'Wholesomeness of Food'. This relates to
a clause in the Code of Professional Conduct, requiring each member "to
take legitimate steps through proper channels to ensure (or assist in
ensuring) the wholesomeness of any food with which he or she is
concerned".
MARKETING TERMS
When used in the labelling, advertising or description of a food,
the main (and sometimes total) role of the terms listed under this
heading is to promote the sale of the product rather than provide
necessary information to the purchaser. Terms often falling into this
category include 'health food', 'designer food', 'functional food',
'improved', 'natural', 'new', 'pure', 'quality', 'selected',
'traditional'.
Food scientists and technologists who are in a position to advise
on product labelling, advertising or promotional material should do
their best to ensure that such terms are not used in ways that could
mislead (see IFST Professional Guideline No 6 'Scientific Issues and
Food Promotion').
