Food grade TBHQ: from antioxidant and preservative to food shelf life extension

Food grade TBHQ (terbutylhydroquinone) is an important food additive, which can prevent oxidative deterioration and spoilage of food ingredients, improve the stability and storage period of food, prevent oxidative rancidity of fats, oils and fat-rich foods, and prevent food from discolouration, browning, and destruction of vitamins. In the food industry, TBHQ is widely used in the processing of edible oils, fats and oils, meat products, baked foods and other fields. Food grade TBHQ is a kind of white to light yellow crystals, with the special smell unique to phenolic substances. Antioxidant Characteristics The antioxidant effect of food grade TBHQ is very obvious, 5-7 times stronger than BHA, BHT, PG. It is suitable for plant and animal fats and fat-rich foods, especially for antioxidant in vegetable oils, especially: salad oil, blending oil, high cooking oil. ◆It can effectively delay the oxidation of oil and fat, improve the stability of food, and significantly extend the shelf life of oil and fat-rich food. ◆ High temperature resistant, can be used in instant noodles, pastries and other fried foods, the highest withstand temperature can be more than 230 ℃. ◆ Multi-functional, can effectively inhibit the growth of bacteria and moulds. Within the scope of additive application, it can inhibit almost all bacteria and ◆Yeast growth, and it has good inhibition effect on moulds harmful to human health such as Aspergillus flavus.
