In the traditional microbial fermentation production, yeast is commonly used to make wine, acetic acid bacteria to produce vinegar, Mucor to produce fermented bean curd and lactic acid bacteria to pro
(2) Mucor can produce protease and lipase, and its principle is: protein protease small molecular peptide and amino acid; Lipase, glycerol and fatty acids. From the point of view of microbial culture, tofu is equivalent to the culture medium of microorganisms. In the process of making sufu, the function of adding salt is: to separate out the water in tofu and harden the tofu block; Inhibit the growth of microorganisms and avoid the deterioration of tofu.
(3) In the process of pickle fermentation, attention should be paid to controlling the pickling time, temperature and salt consumption, otherwise it will easily lead to the proliferation of bacteria and the increase of nitrite content. The fermentation process of kimchi is divided into three stages. In the early stage of fermentation, when vegetables first entered the jar, the active microorganisms were Escherichia coli and yeast, and there were many bubbles in the fermentation process, and the gas in the bubbles was mainly CO2. ..
So the answer is:
(1) acetic acid fermentation C2H5OH+O2→CH3COOH+H2O?
(2) Protease and lipase culture medium separate out water in tofu, which makes the tofu block hard, inhibits microbial growth and avoids tofu deterioration.
(3) Curing time, salt dosage, Escherichia coli and yeast CO2.
