1 Introduction The major food groups contributing to dietary intake of annatto extracts are such items as various cheeses, and snacks. The maximum permitted level of 50 mg/kg is allowed in Red Leicester cheese, 10–25 mg/kg in snacks and 10 mg/kg in liqueurs. 065 mg/kg body weight. 2 Methods of analysis Annatto is a natural food colour and can be identified by characteristic colour reactions. In ‘flavoured’ milk it can be detected by pouring a few millilitres of milk into a flat dish, adding sodium bicarbonate solution and then inserting a strip of filter paper.
