Introduction This International Standard is applicable to most spices and condiments. In v

17、iew 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 indicated in the International Standards giving specifications for the spices or condiments in ques

18、tion. DIN EN ISO 927:2010-03 4 EN ISO 927:2009 (E) 1 Scope This International Standard specifies 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 her

19、bs and spices. 2 Normative references The following referenced documents are indispensable for 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, Sp

20、ices and condiments Sampling 3 Terms and definitions For the purposes of this document, the following 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

21、 EXAMPLE The origin of macro foreign matter can be non-animal (e.g. stems, stones, straw, visible 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 ar

22、e species waste belonging to the plant which the spice or herb belongs EXAMPLE Macro extraneous 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

23、on seeds and leaves, animal excreta pellets and faeces, whole insects and/or large insect fragments, sticks, stems, stones, glass, etc. DIN EN ISO 927:2010-03 5 EN ISO 927:2009 (E) Figure 1 Illustrated definitions 5 Apparatus 5.1 Table and suitable lighting. 5.2 Paper, large, clean white sheets (pos

25、d specified in ISO 948. 7 Procedure 7.1 Laboratory sample size and preparation The laboratory 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

26、laboratory sample size should be about 250 g (see Table 1). Saffron is an exception and the 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 appro

27、priate. The appropriateness is determined based on historical performance, the level of defect under investigation and homogeneity of the samples (see Table 1).

Examine the sample by: a) spreading the product over a wide area of a well-lit (5.1) white sheet (5.2); b) using a spatula (5.3)

31、, move the product in such a manner that it is thoroughly examined; c) separate (5.4) all extraneous and/or foreign matter; d) weigh (5.5) or count (according to 8.1 and 8.2) the extraneous and foreign matter. Report all extraneous and foreign matter. DIN EN ISO 927:2010-03 7 EN ISO 927:2009 (E) 7.3

32、.2 Nutmeg Break 100 nutmeg lengthwise using a butchers knife (5.6). Examine the broken surfaces for insects, insect parts, insect channelling, excreta, or visible mould. Magnification (5.7) can be used to confirm any observations. Report foreign matter and number of positive nuts. 8 Calculation and

33、expression of results 8.1 Extraneous matter and foreign matter The mass fraction of extraneous matter, wEM, and mass fraction of foreign matter, wFM, expressed as percentages, are given by: EMEMS100mwm= EMFMS100mwm= where mEMis the mass, in grams, of non-animal foreign matter; mSis the mass, in gram

34、s, of the laboratory sample or test portion, as appropriate. Express the results to one decimal place. 8.2 Foreign matter from animals Foreign matter from animals can be expressed according to Table 2 as type, name, number, count, mass fraction and percentage mass fraction.
