Problems solved by technology

The anti-oxidation and anti-mold of capers, fungus leaves and poplar leaves for feed have not been studied and applied. The difficulty in their preparation lies in how to ensure their own stability and at the same time make them have a slow-release effect and finally obtain a reasonable Anti-mold and antibacterial effect

[0036] Preparation of composite airgel microporous powder impregnated with poplar leaf extract

[0037] 1. Preparation of caper branch cellulose wet gel precursor

[0038] 1) Pretreatment: cut caper sticks into sections and add them into distilled water at 60°C for constant temperature heating for 60 minutes; dry, pulverize and sieve to obtain caper stick powder with a thickness of 40 μm;

[0039] 2) Caper cellulose extraction: according to the solid-to-liquid ratio of 1:35, add caper twig fiber powder into 0.15mol / L sodium hydroxide solution, stir at 65°C for 30min, reflux, suction filter, and dry Obtain the crude extract powder; according to the solid-to-liquid ratio of 1:10, add the crude extract powder into 0.1mol / L sodium hypochlorite solution, use 0.1mol / L glacial acetic acid to adjust the pH to 4, heat and stir at 70°C for 40min, pump After filtering, washing with water and drying, the caper branch cellulose is obtained;

[0040]3) Preparation of caper branch cellulos...

Abstract

The invention relates to adinandra nitida leaf extract impregnated composite aerogel microporous powder and a preparation method thereof. The microporous powder is prepared from the following components in parts by weight: 100 parts of composite aerogel microporous powder and 100-350 parts of adinandra nitida leaf extract, wherein the composite aerogel microporous powder is prepared from cupparisspinosa branch cellulose wet gel precursor liquid and altingia chinensis leaf extract wet gel precursor liquid; and the average particle size of the composite aerogel microporous powder is not more than 0.5 [mu]m, and the volume ratio of micropores is not less than 85%. According to the adinandra nitida leaf extract impregnated composite aerogel microporous powder, the mildewing time of the feed can be delayed, and the mildewing degree of the feed can be reduced; and the mildew-proof effect equivalent to that of the prior art is obtained while the cost is reduced, so that the chemical mildew-proof agent and the composite mildew-proof agent are effectively replaced, and the aerogel microporous powder is green and non-toxic.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a composite airgel microporous powder impregnated with poplar leaf extract and a preparation method thereof. Background technique [0002] With the rapid economic development, in order to continuously meet the increasing material demand, the scale of animal husbandry is also expanding. Feed mildew has always been the main reason affecting the development of animal husbandry. On the one hand, moldy feed will reduce the storable period of feed, especially in seasons and regions with high humidity, which will easily cause feed failure and cause economic losses; The performance is reduced, and when it is serious, it will cause acute and chronic poisoning of livestock and poultry, and even canceration and deformity, directly endangering the health of livestock and poultry and human beings. Therefore, feed anti-mold agents are widely used in the anti-mold of feed. The exist...
