What is Tertiary Butylhydroquinone used for in food?

In the food industry, TBHQ is used as a preservative for unsaturated vegetable oils and many edible animal fats. It does not change colour even in the presence of iron and does not alter the taste or odour of the material to which it is added. Tertiary butylhydroquinonecan be combined with other preservatives such as butylated hydroxyanisole (BHA). As a food additive, its E number is E319. It is added to various foods. Its main advantage is a longer shelf life. TBHQ is a common antioxidant that prevents fat oxidation. Oxidation can cause foods to lose flavour, discolour and deplete nutritional value. Since oxidation can cause fats to go rancid, TBHQ can also help to extend shelf life and reduce food waste due to spoilage. Tertiary butylhydroquinone is often found in foods such as crackers, fats and oils, chips, doughnuts, some breads, popcorn, other snack foods, and pre-prepared frozen foods.
