Spices and condiments — Determination of extraneous 
matter  and foreign matter content  
 
 
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 herbs and spices.  
 
 
2 Normative references  
 
The following referenced documents are indispensable for the appl ication 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 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  
 
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 nake d 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).

7.3 Examination procedure  
 
7.3.1  All spices and herbs including nutmeg  
 
Weigh (5.5) the sample prepared in 7.1 and 7.2 to the nearest 0,01 
g. 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), 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.

7.3.2  Nutmeg  
 
Break 100 nutmeg lengthwise using a butcher's 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 expression of  results  
 
8.1 Extraneous matter and non-animal foreign  matter  
 
The mass fraction of extraneous matter, wEM, and mass fraction of non -animal foreign matter, wFM, 
expressed as percentages, are given by:  
 
wE
M 
 
 
wF
M = 100  mEM 
mS 
 
= 100  mEM 
mS 
 
where  
 
mEMis the mass, in grams, of extraneous matter;  
mFM is the mass, in grams, of non -animal foreign matter;  
mS is the mass, in grams, 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.  
 
Table 2 — Expression of results  
 
Foreign matter  Expression of results  
Rodent excreta  Count, mg/kg  
Other excreta (including insect and bird excreta)  Type, count, mg/kg  
Whole insects and parts (dead or alive, including mites and psocids)  Name, number  
Larvae  Number  
Mouldy material (all seeds or leaves exhibiting mould and 1/4 or more of their 
total area are considered  mouldy)  Percentage mass fraction  
(calculated according to 8.1)  
 
Insect -defiled product (including leaves, roots and/or seeds)  Percentage mass fraction  
(calculated according to 8.1)
