ISO 15753:2016描述了测定动植物脂肪和油中15种多环芳烃(PAHs)的两种方法:
-一般方法;
-含有短链脂肪酸的椰子油和植物油的特殊方法。
对于萘、苊和芴等极易挥发的化合物,这些方法不是定量的。由于基质本身的干扰,无法使用该方法分析棕榈油和橄榄渣油。
除荧蒽和苯并(g,h,i)苝外,几乎所有分析的化合物的定量限为0,2μg/kg,其中定量限为0,3μg/kg,indeno(1,2,3-
c、 d)芘,其中定量限为1,0μg/kg。
注:附录B中橄榄渣油的结果表明,该方法不适用于此类油。确定的精度数据非常差。
牛奶和奶制品(或来自牛奶和奶制品的脂肪)不在本国际标准的范围内。
ISO 15753:2016 describes two methods for the determination of 15 polycyclic aromatic hydrocarbons (PAHs) in animal and vegetable fats and oils:
- a general method;
- a specific method for coconut oil and vegetable oils with short-chain fatty acids.
These methods are not quantitative for the very volatile compounds such as naphthalene, acenaphthene and fluorene. Due to interferences provided by the matrix itself, palm oil and olive pomace oil cannot be analysed using this method.
The quantification limit is 0,2 μg/kg for almost all compounds analysed, except for fluoranthene and benzo(g,h,i)perylene, where the quantification limit is 0,3 μg/kg, and indeno(1,2,3-c,d)pyrene, where the quantification limit is 1,0 μg/kg.
NOTE The results for olive pomace oil in Annex B show that this method is not applicable to this type of oil. The precision data determined are very poor.
Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this International Standard.
