Embodiment Construction
[0017] The steps of the preparation method of N-acetylgalactosamine disclosed in the present disclosure are as follows:
[0018] The acid binding agent composed of galactosamine hydrochloride, ethanol and sodium ethoxide was neutralized for 20-40 minutes, such as 20 minutes, 25 minutes, 30 minutes, 35 minutes and 40 minutes, and desalted to obtain galactosamine; The weight ratio of ethanol and sodium ethylate in the acid-binding agent is 1:4-6.
[0019] Add chitin enzyme liquid to the obtained galactosamine for fermentation, the chitin enzyme liquid contains 30-60g / L powdered chitin, including N acetylhexosaminidase, chitinase C and chitinase H, the concentration of chitinase C is greater than 0.35g / L, the concentration of chitinase H is greater than 0.07g / L, and the concentration of N-acetylhexosaminidase is 0.055g / L.
[0020] Fermentation is first carried out by high temperature sterilization, the sterilization temperature is 130 degrees, sterilization is 45 minutes, the fe...
