An aromatic organic compound, TBHQ or tert-Butylhydroquinone or tertiary butylhydroquinone is a type of phenol.
Chemically TBHQ is a derivative of hydroquinone, substituted by the tert-butyl group.
Uses of TBHQ
TBHQ has antioxidant properties.
It is used as preservative in foods especially for unsaturated vegetable oils as well as many other edible animal fats.
An excellent quality of TBHQ is that it does change the color, flavor or odor of the food to which it is added.
It can also be used in combination with other food preservatives like butylated hydroxyanisole (BHA).
Its E number is E319 as an additive in foods.
Butylated hydroxyanisole (E 320)
Butylated hydroxyanisole (BHA) is an antioxidant consisting of a mixture of two isomeric organic compounds, 2-tert-butyl-4-hydroxyanisole and 3-tert-butyl-4-hydroxyanisole. It is prepared from 4-methoxyphenol and isobutylene. BHA has been added to edible fats and fat-containing foods for its antioxidant properties as it prevents rancidification of food which creates objectionable odors.
Like butylated hydroxytoluene (BHT), the conjugated aromatic ring of BHA is able to stabilize free radicals, sequestering them.
By acting as free radical scavengers, further free radical reactions are prevented.
