such as butylated hydroxyanisole (BHA). As a food additive,
its E number is E319. It is added to a wide range of foods,
with the highest limit (0.2 gram/kg) permitted for frozen
fish and fish products. Its primary advantage is extending storage life.
It is used industrially as a stabilizer to inhibit autopolymerization of organic peroxides. It is also used as a corrosion inhibitor in biodiesel. In perfumery, it is used as a fixative to lower the evaporation rate and improve stability. It is also added to varnishes, lacquers, resins, and oil-field additives.
TBHQ antioxidant function significantly better than conventional antioxidants, antioxidant ability strong or weak, in order: TBHQ > PG > butylated hydroxytoluene > BHA
