This may be due to TBHQ being more prone to volatilization under high temperature conditions and losing its effectiveness, and under certain conditions, TBHQ may volatilize faster than BHT. Therefore, the application of microcapsule technology can solve this problem under high temperature conditions.

At high temperatures, a series of complex chemical reactions such as oxidation, decomposition, polymerization, and hydrolysis are prone to occur, resulting in a rapid increase in the acid value, peroxide value, and carbon base value of roasted foods. In the later stage of storage and sales, unpleasant odors are easily produced. The use of TBHQ can effectively delay oil oxidation in pastry foods.Baked pastry foods require a higher temperature during the baking process, such as cakes and bread, which require a baking temperature of 160C~190C.

Pastry and bread stored in the air for a long time are prone to spoilage due to oxidation of their lipid components. The oxidation of oil components not only causes food discoloration, discoloration, destruction of vitamin A, D, E, and other components, but also produces odor.

The experimental results show that adding 002% TBHQ to oil can increase the antioxidant stability of the tested oil by 2-5 times, thus extending the shelf life of oil based foods compared to adding traditional antioxidants; And the antioxidant effect increases with the increase of the addition amount; The use of a small amount of synergist in combination with TBHQ can have a synergistic effect on antioxidant activity and enhance its antioxidant effect; The antioxidant effect of TBHQ on different oils is not entirely related to the iodine value, so further research on its application and develo

Pastry and bread stored in the air for a long time are prone to spoilage due to oxidation of their lipid components. The oxidation of oil components not only causes food discoloration, discoloration, destruction of vitamin A, D, E, and other components, but also produces odor. In addition, essential fatty acids such as linoleic acid and linolenic acid in oil are also damaged, reducing the nutritional function of the product. In severe cases, harmful substances such as oxides, peroxides, and decomposition products such as epoxypropylaldehyde can be produced, leading to food poisoning.

In view of the advantages of TBHQ and BHT, in recent years, BHT and TBHQ have become widely used antioxidants in fats and oil-rich foods . It should be pointed out that TBHQ and BHT have small molecular weights, are volatile and easy to sublimate, and under heating conditions, both volatilization and depletion are relatively fast, and the antioxidant performance will be generated through a series of complex redox reactions to produce the corresponding transformation products.
