Example Embodiment

[0045] Example 1: High I+G yeast extract product 1 obtained according to the method of the present invention

[0046] Main equipment: autolysis tank, evaporator; separator, spray tower.

[0047] Production is carried out according to the following process (based on 30 kg of beer yeast paste):

[0048] Preferably, fresh beer yeast paste is transported and stored in a refrigerated truck at a temperature not higher than 15°C, and the storage process is preferably not higher than 5°C. Pass through a 60-200 mesh screen to remove hops and other foreign matter.

[0049] Blend the processed yeast paste to 8-18%, and add 2.0% of the total dry weight of the yeast paste with NaHCO 3 After treating for 2 hours below 10°C, separate it again. Add 1.5% NaHCO 3 It is treated at 10°C or less for 1.5 hours, separated and washed to pH 6.0.

[0050] The concentration of the yeast paste after the above treatment is adjusted to a solid content of 10%, and 7% alcohol is added as an autolysis accelerator. Th...

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...
