Antioxidants as Food Preservatives

Anti Oxidants Article

While commonly regarded for their health benefits, antioxidants are also used as food additives. Antioxidants make an effective guard against food deterioration given that exposure to oxygen and sunlight are the two main factors in oxidation. Food preservatives can include natural antioxidants such as ascorbyl palmitate, tocopherols and tocopherol acetate, as well as synthetic antioxidants such as propyl gallate (PG), tertiary butylhydroquinone (TBHQ), butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and ethoxyquin.
