The work of preparing International Standards is normally carried out through ISO technical

19、 committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with

20、 the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Intern

21、ational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may

22、be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13302 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 12, Sensory analysis. BSISO13302:2003IS:20331 O3002(E) I SO 3002 All irhgts seredevr vIntroduction

23、 It is necessary to prevent materials intended for the packaging of foodstuffs from being the cause of unwanted alterations in odour or flavour. Likewise, it is necessary to take into account the storage conditions of the foodstuffs once they are packed since this can also be one of the causes of mo

24、difications to odour or flavour. Certain types of foodstuff are particularly susceptible to flavour modifications due to packaging materials (e.g. fatty or powdered products having a large area in contact with the packaging). In particular, the packaging material can contaminate the product by trans

25、fer. This transfer can occur by direct contact with the packaging material or, indirectly, by means of the atmosphere created between the packaging and the product. Foreign odours or flavours can also come from the inner or outer layers of the packaging material. The packaging material can also abso

26、rb compounds from foodstuffs and cause modifications of flavours. Food industries should ensure that the packaging they use is the best possible choice with respect to their products. This is why they must have at their disposal methods which allow them to ascertain that the flavour of the foodstuff

27、s is not significantly modified under certain storage conditions. Compounds transferred from packaging materials and responsible for undesired effects on the flavour of food products are usually in very low quantities, often below the detection limits of the analytical techniques, or simply the comp

28、ounds responsible for the changes in flavour have not been identified. Thus, it is necessary to evaluate the sensory properties of packaging materials. This International Standard describes two complementary tests which are not mutually exclusive: assessment of the inherent odour of the packaging ma

29、terial under test (odour test); assessment of the change of flavour of a foodstuff after direct or indirect contact with the packaging material under test in actual conditions or in simulated conditions (contact test). This International Standard was developed by a group composed of sensory analysis

30、 experts and experts from the packaging sector and is based on their experience.

31、International Standard describes methods for assessing the changes caused by packaging to the sensory attributes of foodstuffs or their simulants. The methodology can be used as initial selection to assess a suitable packaging material or as subsequent acceptability screening of individual batches/p

32、roduction run (see Annex A). This International Standard is applicable to all materials usable for packaging foodstuffs (e.g. paper, cardboard, plastic, foils, wood). Moreover, the scope can be extended to any objects intended to come into contact with foodstuffs (e.g. kitchen utensils, coatings, le

33、aflets, or parts of equipment such as seals or piping) with the aim of controlling food compatibility from a sensory point of view according to the legislation in force. 2 Normative references The following referenced documents are indispensable for the application of this document.

38、3002 All irhgts seredevr3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 5492 and the following apply. 3.1 packaging object intended for wrapping or containing, temporarily, a product or series of products during handling, transportation, storage or p

39、resentation, with a view to preserving, protecting or facilitating these operations NOTE This International Standard covers packaging coming into direct contact with foodstuffs. 3.2 new packaging any packaging in which at least one of the constituent elements (e.g. nature of the material, adhesives,

40、 inks, solvents, varnishes) is new or has been modified 3.3 odour sensory attribute perceptible by the olfactory organ on sniffing certain volatile substances 3.4 flavour complex set of olfactory, gustatory and trigeminal sensations perceived during the course of the tasting NOTE The flavour can be

41、influenced by somaesthetic (tactile, thermal, algesic and/or kinesthetic) impressions. 3.5 taint flavour which is foreign to the foodstuff 3.6 off-flavour atypical flavour of the foodstuff, often associated with the deterioration of the foodstuff 3.7 reference material packaging material which does

42、not interfere with the sensory properties of a product NOTE The reference material could be an approved packaging that already exists which complies with the legislation in force. 3.8 assessor sensory any person taking part in a sensory test NOTE A nave assessor is a person who does not meet any par

43、ticular criterion. An initiated assessor is a person who has already participated in a sensory test. 3.9 selected assessor sensory assessor chosen for his/her ability to perform a sensory test 3.10 expert general sense a person who, through knowledge or experience, has competence to give an opinion

44、in the fields about which he/she is consulted NOTE In sensory analysis, there are two types of expert, the “expert assessor” and the “specialized expert assessor”, in conformity with ISO 8586-2. BSISO13302:2003IS:20331 O3002(E) I SO 3002 All irhgts seredevr 33.10.1 expert assessor selected assessor

45、with a high degree of sensory sensitivity and trained in the use of sensory analysis methods and who is able to make consistent and repeatable sensory assessments of various products 3.10.2 specialized expert assessor expert assessor who has additional experience as a specialist in the product and/o

46、r process and/or marketing, and who is able to perform sensory analysis of the product and to evaluate or predict effects of variations relating to raw materials, recipes, processing, storage, ageing, etc. 4 Principle 4.1 Assessment of the inherent odour of the packaging material The packaging mater

47、ial under test is stored in a container under controlled conditions. The odour of the atmosphere developed upon confinement is assessed by means of sensory analysis methods. 4.2 Assessment of the effect of the packaging material on the flavour of the foodstuff The foodstuff and the packaging materia

48、l under test, with direct or indirect contact, are stored in a container under controlled conditions. The flavour changes of the foodstuff are assessed by means of sensory analysis methods. 5 Foodstuff samples 5.1 General CAUTION Hygienic and safety requirements related to the products used shall be

49、 followed. When possible, use the actual foodstuff, method of packing and storage conditions (temperatures, contact time, etc.) for the tests. This is highly recommended for tests performed at the development level. For repeated tests with a panel, use, if possible, the same foodstuff references (same product and same trade name). In the other cases, use a similar foodstuff which approximates the real pro
