The invention relates to the field of liquid dairy product, in particular to a milk oligopeptide added liquid milk and a preparation method thereof. The milk oligopeptide added liquid milk, based on 1000 parts by weight, comprises 942-996 parts of milk, 0-50 parts of white granulated sugar, 3-5 parts of milk oligopeptide, 0.1-1.5 parts of thickening agent and 0.9-1.5 parts of emulsifying agent combination, wherein the emulsifying agent comprises 0.8-1.1 parts by weight of sucrose fatty acid ester with HLB value being 15 and HLB of total emulsifying agent being 9-11. The invention surmounts the technical difficulty that a quantity of milk scale is produced when adding high protein substance in superhigh temperature liquid milk, adds variety of liquid dairy products which are suitable for puerperae, rich in protein and Fe, and has high absorptivity and good mouth feel, and innovates the product structure and formula composition of original compound liquid milk, thus new product varieties appear on market.

The invention relates to an acne-removing conditioner, an acne-removing mask composition and a preparation method of the acne-removing conditioner and the acne-removing mask composition. The acne-removing conditioner is prepared from the following components of 10 to 20 parts of calamine, 0.1 to 2 parts of coated salicylic acid, 0.001 to 0.01 part of oligopeptide-1, 0.001 to 0.01 part of palmitoyl tripeptide-8 and 0.1 to 10 parts of nicotinamide. The acne-removing mask composition is prepared from the components in parts by weight: 50 to 95 parts of aqueous matrix and 5 to 25 parts of oil gel, wherein the water aqueous matrix comprises the acne-removing conditioner and a gel thickening agent; the oil gel comprises grease and a cross-linking agent. According to the acne-removing conditioner, the acne-removing mask composition and the preparation method of the acne-removing conditioner and the acne-removing mask composition, the aqueous matrix and the oil gel are separately stored and are mixed during use, and then the mixture is smeared on the face for use, so that a formed film can be stripped, and a product has the advantages of good skin fitting property, no sensitization and irritation and convenience in use; the preparation method of the acne-removing mask composition is simple and easy to implement, raw materials are easy to obtain, the corresponding aqueous matrix and the oil gel can be separately stored and mixed during use, and the acne-removing mask composition is suitable for large-scale production.

The invention discloses cordyceps sinensis and peony oligopeptide lipid-lowering and anti-aging nutritional powder. The Chinese caterpillar fungus and peony flower beverage is prepared from the following raw materials in percentage by weight: 11 to 13 percent of cordyceps sinensis and peony flower extract whole powder, 5 to 7 percent of peony seed oligopeptide powder, 1 to 3 percent of corn oligopeptide powder, 77 to 82 percent of inulin, 0.08 to 0.12 percent of citric acid mixture and 0.28 to 0.32 percent of stevioside. The cordyceps sinensis and peony oligopeptide whole powder, the peony seed oligopeptide powder, the corn oligopeptide, the inulin and other raw materials are reasonably and organically matched, so that the specific effects of the raw materials are fully reflected in the cordyceps sinensis and peony oligopeptide lipid-lowering and anti-aging nutrition powder product.

The invention provides a method of simply, conveniently and quickly measuring protease activity. The method mainly includes that an oligopeptide compound Suc-Ala-Ala-Pro-Tyr-pNA is utilized as a substrate to prepare a reaction system composed of a solution of the substrate, buffer liquid and protease liquid, protease hydrolyzes peptide bond between tyrosine (Tyr) in oligopeptide and p-nitroaniline(pNA), pNA monomer generated after breaking of the peptide bond has an absorbing peak at OD410, and activity of protease can be obtained by measuring light absorption value of OD410. The method is simple in process operation, short in time consumption and low in sample demand and can measure enzyme activity of multiple samples at the same time and meet needs of large-scale sample measuring.

The present invention belongs to the technical field of medicinal and edible food formulas and new resource foods and specifically provides non-whole nutrient formula food, special whole nutrient formula food or whole nutrient formula food for patients with gastric carcinoma to eat. According to the requirements of General Principles of Special Medical Use Formula Foods, in combination with the constitutive characters of the patients with gastric carcinoma, and based on the essence of traditional Chinese medicine theory, a variety of medicinal and edible traditional Chinese medicines are reasonably combined; a plurality of types of traditional Chinese medicine extract essences which are extracted by a prehydrolysis SBE technology, oligopeptides extracted by biological enzymolysis, prebiotics, amino acids, carbohydrates, fats with healthcare functions, a plurality of types of vitamins and mineral substances are mixed and then treated by other processes, thereby obtaining the formula food. The formula food can be used as a single nutrient source to meet the nutritional requirements of the patients with gastric carcinoma, and also has effects of helping digestion, invigorating stomach, tonifying spleen, excreting dampness, promoting the secretion of saliva or body fluid, moistening dryness, clearing heat, removing toxics, regulating qi to alleviate pain and enhancing immunity.
