Existing as white or light mahogany crystalline powder, Tert-Butyl Hydroquinone (TBHQ) has an exceptional thin fragrance.
Tert-butyl hydroquinone (TBHQ) is a vital product of our food additives and ingredients. It is almost insoluble in water
(about 5 ‰) but is soluble in ethanol, acetic acid, ethyl ester, aether and vegetable oil, lard, and so on. Tert-butyl
hydroquinone plays the role of antisepsis for most oils, especially vegetable oil. It will not change colour when it meets iron and copper, but it will turn pink when there is an alkali.
TBHQ is a highly effective preservative for unsaturated vegetable oils and many edible animal fats. It does not cause discolouration even in the presence of iron and does not change the flavour or odour of the material to which it is added. It can be combined with other preservatives such as butylated hydroxyanisole (BHA). As a food additive, its E number is E319, where it is used as a preservative. It is added to a wide range of foods, with the highest limit (1000 mg/kg) permitted for frozen fish and fish products. Its primary advantage is enhancing storage life.
