The invention relates to a polymer coated vitamin E liposome and a preparation method thereof. The preparation method of the invention comprises the following steps: preparing a vitamin E liposome suspension; adding a polymer into the suspension for coating to obtain a polymer coated vitamin E liposome suspension; obtaining a polymer coated vitamin E proliposome solid powder by spray drying or freeze drying; and before use, adding a proper amount of distilled water as required to obtain the polymer coated vitamin E liposome suspension with the entrapment rate of 82-94%. The polymer coated vitamin E liposome of the invention can obviously reduce the degree of oxidation of vitamin E, reduce the percolation rate, delay the release of the vitamin E in vivo, prolong the cycling time in vivo, and be prepared into the coated type proliposome solid powder which can be more conveniently packed, stored, transported and used.

The invention relates to the extraction technology of a rhizoma coptidis total alkaloid and the process flow is as follows: raw materials (rhizoma coptidis or coptis fibrous roots or coptis leaves), pulverization (Coptis fibrous roots or coptis leaves need no pulverizing.), addition of right amount of sulphuric acid of 0.01 to 10 percent for soaking, heated extraction for four times, preconcentration, sediment of sodium chloride and high-valencied metal salt, filtration, drying and products of rhizoma coptidis total alkaloid. The main active ingredients for the product are berberine, coptisine, jateorrhizine, palmatine, epiberberine and other active coptis ingredients, the content of rhizoma coptidis total alkaloid is over 20 percent, wherein, the content of berberine is over 10 percent. The product adopts coptis fibrous roots and so on as raw materials to extract rhizoma coptidis total alkaloid, which is different from the traditional extraction of berberine. The extraction technology improves the pure quotient of the product and particularly eliminates cold-natured ingredients of toxic and side effect through the operating procedure of impurity eliminating, thereby improving the product quality. Besides the traditionally-utilized berberine, the product still contains a large quantity of other active coptis ingredients such as coptisine, jateorrhizine, palmatine, epiberberine and so on. The product has a higher utilization rate of resources and a higher security of products, and the effective function and action of rhizoma coptidis can be brought into a better play.

The invention discloses a method for producing bovine-bone peptone by enzyme technology, which belongs to the technical field of bioengineering. The method comprises the steps of pretreating fresh bovine bones and then adding enzyme for enzymolysis. The method has the advantages of advanced technique, reasonable process route, thorough enzymolysis, sufficient raw-material utilization, high yield of peptone products, good quality, high amino nitrogen content, high total nitrogen content, plentiful species of amino acid, proper proportion and high biological potency, and reaches reagent-grade product standards. The method takes the bovine bones as raw materials, changes waste into valuables, improves the utilization ratio of the bovine bones in China, reduces environmental pollution, drives the development of the livestock breeding industry and other industries, and remarkably improves the comprehensive benefit of farming and animal husbandry industrialization.

The biotechnological process of producing polypeptide and protein feed is superior to traditional fish meal producing process, which has high protein loss rate, high power consumption, high cost, serious pollution and other demerits. The present invention produces polypeptide paste, polypeptide powder, protein paste or protein powder with fresh low value fishes and shrimp and aquatic animal leftover and through the process including the steps of eliminating impurity, steam to eliminate fat, oil-water separation, crushing, sterilizing, enzymolysis, inactivating enzyme, concentration, drying and others. The present invention has the advantages of high protein content in the products, high bioavailability, no environmental pollution, low power consumption, etc. The products have the effects of promoting animal growth, regulating immunity, preventing and treating diseases, etc. and are used mainly in raising animal and as nitrogen source for biological culture.

The invention relates to a production method of a feed-grade granular calcium hydrogen phosphate III-type product, which comprises the following steps of: mixing strong phosphoric acid with 30-50 wt% of phosphorus pentoxide and a calcium-containing compound according to the Ca / P ratio of 0.75-0.85 in a reactor at high rotating speed greater than and equal to 450 RPM for reaction, continuously feeding produced mixed slurry containing calcium hydrogen phosphate and monocalcium phosphate together with a return material into a mixing granulator for granulation, and feeding a produced feed-grade granular calcium hydrogen phosphate III-type moisture semi-finished product into a drying machine for drying; and screening a dried finished product output by the drying machine to obtain the calcium hydrogen phosphate III-type product, and crushing tailings remained after screening and returning the crushed tailings to the mixing and granulation steps as the return material. With the production method, the feed-grade granular calcium hydrogen phosphate III-type product is directly synthesized in one-step reaction, the production method has low grade requirement for raw materials, short production process flow and high phosphorus utilization rate, and no white fertilizer or waste water is produced; and the granular product does not cake and has good flowability, and the biological value of animals is high.

The invention relates to Chinese herbal medicine feed additive with astragalus root flavor for fattening lambs, which can realize rapid fattening of the lambs under prior feeding conditions. The feed additive is prepared by adopting the steps of mixing and crashing astragalus root, hawthorn, white paeony root and selfheal, and adopting molasses, and the like as carriers for adsorbing, and can be added into feed for usage. The invention improves meat quality, flavor, mutton system water power, and meat tenderness at the same time of prompting the nutrient digestibility ratio of the lamb feed and improving the return interest of the feed according to digestion functions.

The process of producing feed grade calcium phosphate features that the calcium phosphate producing process includes the first liquid phase neutralizing reaction between dilute phosphoric acid and calcium containing compound in the reactor to produce calcium dihydrogen phosphate slurry, the subsequent adding calcium containing compound for the second liquid phase neutralizing reaction to produce mixture slurry of calcium hydrogen phosphate and calcium dihydrogen phosphate, and the spray drying of the slurry to obtain the calcium phosphate product. The production process has no produced white fertilizer and waste water, high phosphorus utilization rate, low production cost, less environmental pollution and well preservation of crystalline water resulting in high biological potency.

The invention relates to a plant protein extraction process technology, that is, a process for extracting grape seed polypeptide protein by biological enzyme method. The grape seed is used as a raw material, crushed, softened with water, hydrolyzed with endo-cut slightly acidic cellulase and papain mixed enzyme, exo-cut rice koji enzyme hydrolyzed, separated, concentrated and dusted to obtain powdery grape seed polypeptide protein. It has the characteristics of no peculiar taste, high protein extraction rate, low production cost, and maximum protection of raw materials without loss of nutrition during processing.
