Embodiment 1

[0026] A method for extracting polysaccharides from silverfish, comprising the steps of:

[0027] (1) Get fresh silverfish, wash and dry, then pulverize it, and cross a 50-mesh sieve to obtain silverfish meal;

[0028] (2) Add the fish meal of step (1) into 65°C water, add NaOH of 1mol / L concentration to adjust the concentration of dilute lye to be 0.02mol / L, then add NaCl to adjust the sodium ion concentration to be 0.05mol / L, and extract 2 hour, filter and collect the filtrate;

[0029] (3) After adding the dehydrated alcohol of 4 volume ratios to the filtrate of step (2), centrifugation, the centrifugal speed is 4000r / min, and the precipitate is collected;

[0030] (4) Rinse the precipitate in step (3) with absolute ethanol, and air-dry to obtain silverfish polysaccharide.

Embodiment 2

[0032] A method for extracting polysaccharides from silverfish, comprising the steps of:

[0033] (1) Get fresh silverfish, wash and dry, then pulverize it, and cross a 40-mesh sieve to obtain silverfish meal;

[0034] (2) Add the silver fish meal of step (1) into 50°C water, add NaOH of 1mol / L concentration to adjust the concentration of dilute lye to 0.01mol / L, then add NaCl to adjust the sodium ion concentration to 0.05mol / L, and extract 1 hour, filter and collect the filtrate;

[0035] (3) After adding the dehydrated alcohol of 3 volume ratios to the filtrate of step (2), centrifuge, the centrifugal speed is 3000r / min, and collect the precipitate;

[0036] (4) Rinse the precipitate in step (3) with absolute ethanol, and air-dry to obtain silverfish polysaccharide.

Embodiment 3

[0038] A method for extracting polysaccharides from silverfish, comprising the steps of:

[0039] (1) Get fresh silverfish, wash and dry, then pulverize it, and cross a 60-mesh sieve to obtain silverfish meal;

[0040] (2) Add the silverfish powder of step (1) into 80°C water, add NaOH of 1mol / L concentration to adjust the dilute lye concentration to be 0.03mol / L, then add NaCl to adjust the sodium ion concentration to be 0.05mol / L, and extract 3 hour, filter and collect the filtrate;

[0041] (3) After adding the dehydrated alcohol of 5 volume ratios to the filtrate of step (2), centrifugation, the centrifugal speed is 5000r / min, and the precipitate is collected;

[0042] (4) Rinse the precipitate in step (3) with absolute ethanol, and air-dry to obtain silverfish polysaccharide.

Abstract

The invention discloses an extraction method and application of silverfish polysaccharide and further provides a formula capable of preparing pet feed. Main operation of the extraction of the silverfish polysaccharide comprises the following steps: washing and crushing, taking sodium chloride to extract with the assistance of diluted alkali liquid, and then precipitating with ethanol. The silverfish polysaccharide prepared by the invention has the advantages that raw materials are easy to obtain and cheap, the purity is relatively high and the utilization vale is relatively high.

Description

technical field [0001] The invention relates to a method for extracting polysaccharides, in particular to a method for extracting polysaccharides from silverfish. Background technique: [0002] Silverfish, also known as scissor insects, silverfish, wallfish, swallowtails, etc., is a relatively primitive small wingless insect belonging to the order Thysanoptera and the family Silverfish. The feeding habits of silverfish larvae and adults are similar, and especially Likes carbohydrates. Correspondingly, a higher proportion of polysaccharides is accumulated in silverfish. [0003] Insect polysaccharides are soluble organic matter after deacetylation of insect chitin, and their application in agriculture can be used as a soil conditioner to improve the physical structure of soil, and can also be used as a vegetable preservative, insecticide, growth regulator, etc. [0004] Seeds treated with insect polysaccharides can effectively improve the survival rate of seeds. Insect poly...
