Embodiment 1
[0048] Embodiment 1: the preparation method of white and water-soluble polysaccharide
[0049] Crush 100kg of dry white powder, add 1000L of amylase aqueous solution to make the final concentration of amylase above 2U, heat it at 40°C for 4 hours to obtain a hydrolysis mixture; Membrane filtration once to obtain filtrate I and filter residue I; Concentrate filtrate I under reduced pressure at 50-60°C to 1 / 15 of the original volume, then add 95% ethanol until the final concentration reaches more than 80%, alcohol precipitation for 10-20h , filter to obtain filtrate II and filter residue II, and concentrate and crystallize filtrate II to obtain glucose; add neutral protease solution to filter residue II so that the final concentration of neutral protease is above 5U, and after hydrolysis for 30 minutes, keep warm at 80-90°C for 10 minutes , filtered once with a 0.22 μm ceramic membrane to obtain the filtrate III, and then separated the filtrate III on a SEPHADEX G-15 column, and...
Embodiment 1
[0051]According to the preparation process of Baiji polysaccharides introduced by the publication number CN101906169A: pulverize 10 kg of Baiji decoction pieces with a pre-installed 1.2mm sieve, and make all of them pass through the No. 2 sieve to obtain Baiji coarse powder. Put white and coarse powder and 500kg of primary reverse osmosis water together in a mixing tank, and stir for 15 minutes to make the mixture evenly into white and suspension. Input the bletilla suspension into the high-pressure homogenizer, and adjust the pressure of the pump body of the high-pressure homogenizer to 45-55MPa. The high-pressure homogenized homogenate is centrifuged in a three-legged centrifuge to collect the centrifugate. Add 2 kg of talcum powder and 2 kg of diatomaceous earth to the centrifugal liquid, mix well, and circulate and filter through a diatomaceous earth filter until the filtrate is almost colorless and clear, then collect the filtrate. Filter the media filtrate through a mic...
Embodiment 2
[0053] According to the publication number CN103044560A, the preparation method of Baiji polysaccharides is as follows: take 10 kg of Baiji tubers, pulverize them, pass through a 20-mesh sieve, add 2 to 4 times the mass and volume of 70 to 90% ethanol to soak for 4 hours, and drain the ethanol. Then add 10-20 times of raw material quality deionized water for extraction, temperature 60-80°C, stir and extract for 3-4 hours, filter and separate the filter residue, centrifuge the filtrate at 8000r / min for 15min, and the supernatant is concentrated to the original volume by a rotary evaporator 1 / 3 of its volume, add 80-95% ethanol according to its volume 2-4 times, set aside for precipitation at 4-8°C for 8 hours, filter and wash to obtain white and crude polysaccharides, and obtain white and crude polysaccharides after vacuum drying, the concentration of which is 2 ~5%, add papain 1~12mg / g for hydrolysis, the pH of the hydrolysis system is 5.5~8.5, the hydrolysis temperature is 40~...
