The application discloses a method for preparing mesoporous zeolite under normal temperature and pressure and application thereof, and the preparation method comprises the following steps: (1) preparation of a functional protein biomodule: cationic polypeptide is loaded on yeast to obtain a biomodule aqueous solution; (2) deposition of silicon and aluminum: the pH of the biomodule solution obtained in the step (1) is adjusted to neutral, then a silicon source, an aluminum source and a titanium source are added into the solution, and the solution is incubated on a shaking table for 3 days; (3) calcination: the solid obtained in the step (2) is collected by centrifugation, washed with ethanol and water alternately for 3 times, and calcined at 500 DEG C for 4h under an air atmosphere to obtain a zeolite molecular sieve adsorption material. The application can prepare porous molecular sieve small balls by using a simple method, and can provide a brand-new thought for synthesizing molecular sieve materials.

The application discloses a plant composition with soothing effect and a preparation method and application thereof, and the composition comprises saponins extracted from radix cynanchi rossii and radix anemarrhenae, and polysaccharides extracted from the radix anemarrhenae, and the mass ratio of the saponins to the polysaccharides is (1-5):(1-3). The technical scheme of the application is as follows: the radix cynanchi rossii and the radix anemarrhenae are mixed in a certain proportion, crushed, extracted by an alcohol solution, and then saponins are obtained through composite membrane separation; the remaining residues are extracted by water, impurities are removed by a clarifying agent, and the radix anemarrhena polysaccharides are obtained through ultrafiltration; and the saponins and the polysaccharides are compounded in a certain proportion, supplemented by polyhydric alcohol to be dissolved, so that the composition with the soothing effect is obtained, and the composition can be applied to the preparation of skin care cosmetics, especially soothing and anti-irritation products.

The invention discloses a silver removal method for preparing electrolyte for high-purity copper, and relates to the technical field of non-ferrous metal hydrometallurgy. The method specifically comprises the following steps that electrolyte for preparing high-purity copper in an electrolysis device is extracted in the electrolysis process, a silver removal agent is added into the electrolyte for preparing the high-purity copper, then stirring reaction is conducted, and the reacted electrolyte for the high-purity copper is obtained; and precisely filtering the reacted electrolyte for the high-purity copper, wherein the obtained filtrate is the electrolyte for preparing the high-purity copper after silver removal. According to the technology, the technical problem that the Ag content in the cathode high-purity copper obtained through electrolysis or electrodeposition exceeds 5N and above high-purity copper is solved, the technology has the advantages of being deep and environmentally friendly, equipment is simple, and the process is short.

The application discloses a DPP-IV inhibiting peptide-producing lactobacillus helveticus, a goat milk with blood sugar reduction and a preparation method thereof, and relates to taking goat milk as raw material, fermenting the goat milk by using the DPP-IV inhibiting peptide-producing lactobacillus helveticus KD12 to obtain the goat milk fermented by the lactic acid bacteria containing DPP-IV inhibiting peptide with blood sugar reduction, and preparing the goat milk powder fermented by the lactic acid bacteria containing DPP-IV inhibiting peptide with blood sugar reduction through drying after fermentation. The lactic acid bacteria of the goat milk fermented by the lactic acid bacteria with blood sugar reduction is inactivated to obtain the goat milk with postbiotics with blood sugar reduction, and after concentration, the goat milk powder with postbiotics with blood sugar reduction is obtained through drying. The goat milk with blood sugar reduction provided by the application has a high DPP-IV inhibition rate, can be used for inhibiting DPP-IV activity after being eaten by consumers, thereby reducing blood sugar, reducing the dosage of blood sugar reduction drugs, and thereby reducing the side effects caused by the blood sugar reduction drugs.
