The order of antioxidant activity in soybean oil is TBHQ>Vc>VE>catechins>BHT. Among them, TBHQ, VE, and BHT have good oil solubility and do not change color after heating, making them suitable for use as advanced soybean oil antioxidants. The antioxidant effect of BHT can only be displayed after a long time. Adding 20mg/kg to oil for short-term storage is better than adding 100mg/kg. Although Vc and catechins have strong antioxidant effects, they are difficult to dissolve in oil and have poor thermal stability.

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.

The seed method first completely dissolves TBHQ in a small amount of oil or 95% alcohol solution, and prepares 5-10% TBHQ oil or alcohol solution. Then, directly or with a measuring device, it is added to the fat or oil and stirred evenly.The pumping method injects the TBHQ concentrated solution prepared by the seed method into a pipeline with a fixed flow rate and flow rate of fat or oil that needs to be stable at a specified proportion through a stainless steel quantitative pump.

Using isobutylene as an alkylation reagent requires a reaction under closed conditions, which can also be catalyzed by strong acids. In a mixed solvent of xylene and ketone, 85% phosphoric acid is used as a catalyst [8], and isobutylene is added to synthesize tert butylhydroquinone. The selectivity of the single tert butylation reaction can reach over 90%. Cationic resin [9] can also serve as a catalyst for this reaction, but the effect is not very ideal.

There are two types of antioxidants, one is chemical synthesized and the other is natural antioxidants. Chemical synthesis, such as BHT, BHQ, TBHQ, ethoxyquinoline, PE, etc., these are considered to be called chemical synthesis of antioxidants, these antioxidants have been banned in Europe, that in China and the United States, is the amount of additive per kilogram can not be greater than 0.2, these chemical synthesis of antioxidants, it is true that there is now some controversy, but the antioxidant effect is relatively good.

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.
