Food antioxidants are food additives that can prevent or delay food oxidation and deterioration, improve food stability and prolong storage life. Oxidation will not only make the oil in the food deteriorates, but also make the food fade, discolor and destroy vitamins, so as to reduce the sensory quality and nutritional value of food, and even produce harmful substances, causing food poisoning. We provide natural food antioxidants, including tea polyphenols, rosemary extract, natural vitamin E, etc. Synthetic antioxidants include propyl gallate, tert-butylhydroquinone, butylhydroxyanisole, dibutyl hydroxytoluene, isoascorbic acid and so on.
