Abstract

The invention discloses a compound emulsion stabilizer containing 12.5 to 20 percent of k type carrageenan, 12.5 to 58.3 percent of HLB which is 11 to 15 of sucrose ester, 25 to 50 percent of molecular distilled monoglyceride and 0 to 40 percent of hydroxylating modified soybean phosphatide, wherein the percent is the mass percent of each component accounting for the total compound emulsion stabilizer. The invention also relates to ultra-high-temperature sterilized milk containing the compound emulsion stabilizer. By the compound emulsion stabilizer, the shelf life of an ultra-high-temperature sterilized milk product containing the compound emulsion stabilizer can be prolonged from 6 months to 9 months, the tissue state is favorable, and protein precipitation and obvious fat suspension can not occur; and the production pressure of an enterprise is further slowed down, the circulation period of batch products is increased, and the loss of the enterprise is lowered.

Description

technical field [0001] The invention relates to a compound emulsification stabilizer and ultra-high temperature sterilized milk containing the same. Background technique [0002] Ultra-high temperature sterilized milk has a long shelf life, can break through regional restrictions, and has strong market liquidity. At present, the shelf life of ultra-high temperature sterilized milk is generally 6 months, and there are products of about 8 months, but the tissue state is generally not ideal after 8 months. The extension of shelf life can reduce the production pressure of enterprises, increase the circulation cycle of batch products, and reduce the loss of enterprises. UHT treatment makes the number of microorganisms in the UHT milk system reach the commercial sterile level, therefore, the product deterioration caused by microorganisms is not the limiting factor of its shelf life. The milk system is generally composed of protein, fat, sugar and other nutrients. It is an object...
