Propylene polymerization inhibitor TBHQ
It is soluble in ethanol, acetic acid, ethyl ester, isopropanol, ether, and oils, and is almost insoluble in water (25 ℃,<1%; 95 ℃, 5%). TBHQ is an oil soluble antioxidant that can prevent or delay the oxidation and deterioration of fats in food.It can effectively delay oil oxidation, improve food stability, and significantly extend the shelf life of oil and fat rich foods.High temperature resistant, can be used for instant noodles, pastries, and other fried foods, with a maximum withstand temperature of 230 "C or above.
TBHQ can be used for edible oils, fried foods, dried fish products, biscuits, instant noodles, instant boiled rice, canned dried fruits, pickled meat products.This product does not affect the color and flavor of food, and is not used for coloring iron containing foods.The antioxidant effect of this product is very ideal, 5-7 times stronger than BHA, BHT, and PG. Suitable for animal and vegetable fats and fatty foods, especially in vegetable oils, it is the preferred antioxidant for salad oil, blended oil, and high cooking oil.
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. Ensure sufficient turbulence is generated in the pipeline to ensure uniform distribution of TBHQ.
Heat the oil directly to 35-60C, add TBHQ in the required proportion, vigorously stir for 10-15 minutes to dissolve it, and then continue stirring (without vigorously stirring to prevent excessive air from entering) for about 20 minutes to ensure uniform distribution of TBHQ.
