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.

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.

Possible reaction pathways of 2,5-di-tert-butyl-hydroquinone (2,5-DTBHQ).Valgimigli et al. proposed a mechanism wherein semiquinone (2) reacts with molecular oxygen to produce 2,5-di-tert-butyl-1,4-benzoquinone (2,5-DTBBQ) and hydroperoxyl radical (HOO∙). The semiquinone (2) terminates a second propagation chain via either hydrogen abstraction (Reaction II) or addition reaction (Reaction IV) and these reaction pathways play a very critical role in the inhibition process.

TBHQ has good oil solubility and thermal stability, and does not change in color after heating.They are only suitable for high water content oil and fat foods such as biscuits, instant noodles, artificial milk oil, and mayonnaise. When the oil contains a large amount of metal ions and oxygen, the addition of antioxidants can inhibit the formation of peroxides.Oxidized fish oil is harmful to human health, so it is important to prevent oxidation and improve the stability of fish oil.
