Embodiment 1

[0017] A kind of preparation method of high-purity squash gum, its concrete steps comprise:

[0018] Put the clean and dry Squat seeds into a pulverizer, put them into a reaction pot after passing through 60 meshes, add 5 times the amount of ethanol, and add an appropriate amount of sodium bisulfate solution to make the ethanol slightly alkaline, stir and soak for 10 hours, vacuum filter and separate, The filter cake was rinsed with alkaline ethanol for 3 times, filtered to obtain the filter cake, put it into 20 times the amount of deionized water, soaked for 2 hours, put it in a high-speed beater, beat it into a slurry, then transferred it to the extractor, and added the filter cake Measure 2% cellulase, stir for 60 minutes at 55°C and pH 6.8, then add 1% neutral protease, continue to stir for 100 minutes, quickly heat up to 98°C to inactivate the enzyme, and keep warm for extraction 20min, centrifugal sedimentation separation, get centrifugate, filter residue soaked with wat...

Embodiment 2

[0020] A kind of preparation method of high-purity squash gum, its concrete steps comprise:

[0021] Put the clean and dry Squat seeds into the pulverizer, put them into the reaction pot after passing through 80 meshes, add 7 times the amount of ethanol, and add an appropriate amount of sodium bisulfate solution to make the ethanol slightly alkaline, stir and soak for 8 hours, vacuum filter and separate, Rinse the filter cake twice with alkaline ethanol, filter the filter cake, put it into 15 times the amount of deionized water, soak it for 2 hours, put it in a high-speed beater, beat it into a slurry, transfer it to the extractor, and add the filter cake Measure 3% cellulase, stir for 80 minutes at 45°C and pH 6.5, then add 1% neutral protease, continue to stir for 80 minutes, quickly heat up to 98°C to inactivate the enzyme, and keep warm for leaching 30min, centrifugal sedimentation and separation, get centrifugate, filter residue soaked with water 3 times, each time 30min,...

Embodiment 3

[0023] A kind of preparation method of high-purity squash gum, its concrete steps comprise:

[0024] Put the clean and dry Squat seeds into the pulverizer, put them into the reaction pot after passing through 120 meshes, add 8 times the amount of ethanol, and add an appropriate amount of sodium bisulfate solution to make the ethanol slightly alkaline, stir and soak for 8 hours, vacuum filter and separate, The filter cake is then rinsed with alkaline ethanol for 2-3 times, filtered to obtain the filter cake, put it into 15 times the amount of deionized water, soak it for 2 hours, put it in a high-speed beater, beat it into a slurry, transfer it to the extractor, add Filter cake with 3% cellulase, under the conditions of 50°C and pH7, stir for 80 minutes, then add 1% neutral protease, continue to stir for 100 minutes, quickly raise the temperature to 98°C to inactivate the enzyme, and keep warm for leaching 30min, centrifugation and sedimentation separation, to obtain centrifuga...

Abstract

The invention discloses a preparation method of a high-purity sesbania gum, and belongs to the biochemical engineering technical field. The method includes the steps of material preparation, impurity removal, filtration, enzymolysis, penetration and drying. Compared with a technology for extracting a sesbania gum by a traditional extensive physical method, the preparation method applies a modern green new technology, ensures the quality of the sesbania gum, improves the purity of the sesbania gum, and has no pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of biochemical industry, and in particular relates to a preparation method of high-purity squash gum. Background technique [0002] Squat Gum is a kind of vegetable glue extracted from the endosperm of natural plant Squatia seeds. It is insoluble in organic solvents such as ethanol, acetone, ether, etc., but easily soluble in water. It can be dispersed in cold water at room temperature and is viscous. It forms a high-viscosity hydrosol, which has flocculation and sedimentation, strong cross-linking performance, extremely low toxicity, and is safe to use. Therefore, it is widely used in food processing industry, chemical industry, petroleum industry, coal industry, paper industry, environmental protection, etc. widely used in the field. [0003] The traditional process uses physical methods such as rolling and crushing, which are environmentally friendly, but the extraction rate is not high enough, and there...
