Summary	This standard specifies the method for the determination of cyanide in food. The first method of spectrophotometry is suitable for the determination of cyanide in distilled wine and its preparations, edible alcohol, tapioca flour, packaged drinking water and mineral water. The second method gas chromatography and the third method gas chromatography-mass spectrometry are suitable for the determination of cyanide in liquor, edible alcohol, grain, packaged drinking water and mineral water. The fourth method of ion chromatography is suitable for the determination of cyanide in distilled wine and its prepared wine, edible alcohol, packaged drinking water, mineral water and beverages (with almonds as raw material). The fifth method of flow injection/continuous flow-spectrophotometry is suitable for the determination of cyanide in distilled wine and its preparations, edible alcohol, packaged drinking water and mineral water.
