Food additives refer to the addition of artificial or natural substances into food for the purpose of improving the variety of food and its color, aroma and taste, as well as the processing technology needs for preservation and preservatives.China strictly stipulates that the variety, scope and content of relevant food additives must be consistent with the provisions in GB2760.Otherwise, when the food contains too much food additives, it is very easy to threaten the health of consumers, and even lead to food poisoning.
