Abstract

The invention provides a method for treating waste beer yeast paste to produce yeast extract of disodium 5'-inosinate and disodium 5'-guanylate (I+G). The method comprises the following steps: (1) separating or squeezing the waste beer yeast paste; (2) debittering; (3) self-dissolving; (4) carrying out enzymolysis; (5) raising the temprature and carrying out enzyme deactivation; (6) separating and evaporating; and (7) drying. According to the method provided by the invention, the content of the obtained yeast extract of the disodium 5'-inosinate and the disodium 5'-guanylate is high; additives are not added and the utilization rate of protein is high; and the content of total nitrogen and ammonia nitrogen is high. According to the method provided by the invention, the bitter taste of the product can be reduced and the umami is enhanced; and meanwhile, the mellow taste is improved and the peculiar smell is balanced, and the comprehensive taste of the product can be effectively improved.

Description

technical field

[0001] The invention relates to a production method of yeast extract, in particular to a method for producing homoinosinate disodium and guanylate disodium (I+G) yeast extract from waste beer yeast sludge. Background technique

[0002] Yeast extract is a nutritional flavor enhancer prepared from edible baker's yeast or brewer's yeast. Yeast extract is a natural food ingredient with high nutritional value, so it is widely used in food processing industries such as instant noodles, meat products, soy sauce, and chicken essence.

[0003] China is the second largest beer producing country in the world, and our country has a large amount of waste beer yeast slime resources after beer fermentation. In 2013, my country's beer production was about 50.615 million tons, and it is expected to increase by 6% in 2014. It is estimated that the production of beer is 53.6519 million tons. According to the calculation of 1.5% yeast slime for every ton of beer produced, it is...
