15、l Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been es

16、tablished 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 the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardi

17、zation. 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 International Standards adopted by the technical committees are circulated to the member bodies for vot

18、ing. 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 be the subject of patent rights. ISO shall not be held responsible for identifying any or all suc

20、SO 2012Introduction This International Standard is applicable to most spices and condiments. In view of the number and variety of such products, however, it may be necessary to modify the method or even to choose a method more suitable to a particular case. Such modifications or other methods are in

21、dicated in the International Standards giving specifications for the spices or condiments in question. BS EN ISO 927:2009 ISO 927:2009 (E)EN INTERNATIONAL STANDARD ISO 20 1Spices and condiments Determination of extraneous matter and foreign matter content 1 Scope This International Standard specifie

22、s a general procedure for visual examination, or with magnification not exceeding 10 times, of whole spices for the determination of macro filth. This International Standard is applicable to dehydrated herbs and spices. 2 Normative references The following referenced documents are indispensable for

23、the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 948, Spices and condiments Sampling 3 Terms and definitions For the purposes of this document, the fol

24、lowing terms and definitions apply. 3.1 macro foreign matter all matter visible to the naked eye or with a maximum 10 times magnifying power that is not part of the plant to which the spice or herb belongs EXAMPLE The origin of macro foreign matter can be non-animal (e.g. stems, stones, straw, visib

25、le moulds) or animal (e.g. excreta, insects, and insect-defiled product) foreign matter. 3.2 macro extraneous matter all matter visible to the naked eye or with a maximum 10 times magnifying power which are species waste belonging to the plant which the spice or herb belongs EXAMPLE Macro extraneous

26、 matter can be floral waste. Figure 1 summarizes these definitions. 4 Principle This method should be used by all laboratories which perform macro extraneous and foreign matter analyses for: suspect mould on seeds and leaves, animal excreta pellets and faeces, whole insects and/or large insect fragm

27、ents, sticks, stems, stones, glass, etc. 12BS EN ISO 927:2009 EN ISO 927:2009 (E)2 ISO 2012Figure 1 Illustrated definitions 5 Apparatus 5.1 Table and suitable lighting. 5.2 Paper, large, clean white sheets (possibly glazed). 5.3 Spatulas, selection, of small and large sizes. 5.4 Sample splitter, Jon

29、ory sample should be a composite sample taken from different parts of the lot. For high bulk density products, the laboratory sample size should be about 500 g (see Table 1). For low bulk density products, the laboratory sample size should be about 250 g (see Table 1). Saffron is an exception and th

30、e laboratory sample size should be 3 g. 7.2 Test portion The laboratory sample should be homogenized before taking the test portion. The entire laboratory sample is to be analysed unless a test portion is appropriate. The appropriateness is determined based on historical performance, the level of de

31、fect under investigation and homogeneity of the samples (see Table 1).
