Epices — Determination de Ia teneur en matières etrangéres.
This ISO 927 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 herbs and spices.

ISO 948. Spices and condiments — Sampling
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
macro foreign matter
all matter visible to the naked eye or with a maximum 10 times magnifying power that is not part ot me piant to which the spice or herb belongs
EXAMPLE The origin of macro foreign matter can be non-animal (e.g. stems, stones, straw, visib’e 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 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 fragments, sticks, stems, stones, glass, etc.
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, Jones sampler or riffle divider.
5.5 Balance, capable of being read to at least the nearest 0.001 g.
5.6 Butcher’s knife or any other suitable tool.
5.7 MagnifyIng glass
6 Sampling
Sample the material by the method 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 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 appropriate. The appropriateness is determined based on historical performance, the level of defect under investigation and homogeneity of the samples (see Table 1).ISO 927-2009 pdf free download.
