Oxidation is one of the most common deterioration phenomena encountered in food processing and preservation  (Thailand food Ingredient supplier) . After food is oxidized, not only bad changes will take place in color, aroma and taste, but also toxic and harmful substances may be produced. In order to prevent the deterioration of food caused by oxidation, National food standard stipulates that a small amount of substances that can delay or hinder oxidation can be added to food, which are antioxidants.

There are many antioxidants in use and can be classified according to different standards. According to their sources, antioxidants can be divided into chemically synthesized antioxidants and natural antioxidants. If classified according to their mode of action, antioxidants can be divided into free radical absorbers, metal ion chelating agents, oxygen scavengers, hydroperoxide decomposers, enzyme antioxidants, ultraviolet absorbers or singlet oxygen quenching agents. Common antioxidants are tea polyphenols (TP), tocopherols, flavonoids, butyl hydroxyanisole (BHA)  (Thailand food flavour wholesale) , dibutyl hydroxytoluene (BHT)  (Thailand food Ingredient supplier) , tert butyl hydroquinone (TBHQ) and so on  (Thailand food flavour wholesale) .
