2,5-Di-tert-butyl-1,4-benzenediol
At present, the most commonly used antioxidants for oils and their products are BHA, BHT, PG, TBHQ, and tocopherols. As for vegetable oils, their antioxidant capacity is in the order of TBHQ>PG>BHT>BHA. As for animal fats, the order of their antioxidant capacity is TBHQ>PG>BHA>BHT. For anhydrous milk fat, their antioxidant capacity is in the order of PG>TBHQ>BHA>tocopherols. For certain processed foods rich in oil, such as fried potato chips, which have a large surface area and are prone to oxidation and spoilage, the order of antioxidant capacity is: TBHQ>PG>BHT>BHA.
When the tert butanol process encounters bottlenecks, replacing tert butanol with isobutene is a feasible breakthrough direction. Patent [10] discloses a method for preparing 2-tert butylhydroquinone and co producing BHA using isobutene as an alkylation reagent, which has good selectivity and high raw material utilization rate.
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. Ensure sufficient turbulence is generated in the pipeline to ensure uniform distribution of TBHQ
As one of the internationally recognized best food antioxidants, it has been widely used in the oil and fat containing food industry in dozens of countries and regions, and has quickly replaced traditional antioxidants. The product is high-quality and cost-effective, making it very suitable for enterprises such as edible oils and instant noodles to use
High temperature resistant, can be used for instant noodles, pastries, and other fried foods, with a maximum withstand temperature of 230 "C or above.
One dose is versatile and can effectively inhibit the growth of bacteria and molds. Within the scope of added applications, it can inhibit the growth of almost all bacteria and yeast, and has a good inhibitory effect on mold harmful to human health such as Aspergillus flavus
