Method of applying nontoxic deforming agent to liquid edible fungus fermentation tank

Abstract

The invention discloses a method of applying a nontoxic deforming agent to a liquid edible fungus fermentation tank; the liquid edible fungus fermentation tank must be cleaned thoroughly and inspected after every use or before reuse; the method comprises the following steps: boiling the tank to disinfect; adding sucrose, bean flour and a monopotassium phosphate main ingredient to the liquid edible fungus fermentation tank; adding water and stirring; injecting a deforming agent; selecting a proper cultivating process, wherein soybean oil serves as the defoaming agent, and is added and adjusted depending on a volume of 3-8%; the soybean oil, which is lower than polyoxypropylene-polyoxyethylene glycerol ether in specific gravity, is easier to float on surface in a cultivating environment that the fermentation tank is strenuous and is longer to act on an effective area of foam; scientific name of the polyoxypropylene-polyoxyethylene glycerol ether is polyether, and has low toxicity although being under edible grade, while the soybean oil, as edible oil, contains a great amount of linoleic acid which is fatty acid essential to body, free from toxicity and harm and is more suitable for massive use of food-grade fermentation tank products; and market price of the soybean oil is lower than that of the polyoxypropylene-polyoxyethylene glycerol ether, so as to reduce manufacturing cost.

Description

technical field [0001] The invention relates to a method for using a defoamer, in particular to a method for applying a nontoxic defoamer to a liquid edible fungus fermenter, and belongs to the field of biotechnology applications. Background technique [0002] With the development of science and technology, especially the interpenetration and intersection of microbiology, bacteriology, fermentation technology and engineering, especially the development of fermentation product separation technology, the application of edible fungus liquid fermentation technology is wider and the prospect is broader. . [0003] Defoamer, also known as defoamer or foam breaker, will produce a lot of foam in the edible fungus liquid fermentation technology, and it is necessary to add a defoamer to suppress the foam; there are many types of defoamers, organosiloxane, poly Ether, silicon and ether grafted, containing amines, imines and amides, have the characteristics of faster defoaming speed, l...

Problems solved by technology

[0004] In the medical field and the production process of edible fungus strains, it is often necessary to make fermenters for production or strain propagation. During the sterilization process of fermenters, due to the high temperature and pressure generated inside, and the filtered clean air fed into the fermenters, etc. Factors lead to the production of a large amount of foam. In order to prevent the appearance of foam, foam enemy is often added as a defoamer. Long-term use of foam enemy defoamers brings the following problems: the production of defoamers is complicated and requires high costs. The dosage is too large, and a large amount of use will increase the cost
