The dog food is manufactured by adding tea polyphenol with additive amount of reaching 0.1-1 part, by weight, into 100 parts, by weight, of dog food, and going through procedure of mixing, stirring, extruding, puffing and the like. The remaining components of the dog food comprise, by weight, 15-25 parts of refined rice, 15-25 parts of bean pulp, 15-35 parts of corn, 5-15 parts of wheatmeal, 10-25 parts of fish meal, 5-10 parts of yeast powder, 1-3 parts of calcium hydrophosphate, 0.1-0.5 part of edible salt, 0.1-0.5 part of vitamin premix, 0.1-0.5 part of mineral premix, and 0.05-0.15 part of potassium sorbate. According to the dog food, tea polyphenol is used as functional feed supplements in the production of commodity dog food. Consequently, the dog food can effectively improve the antioxidant ability and the intestinal health conditions of dogs, and achieves double effects of guaranteeing the quality of commodities and caring health in a functional mode.

The invention relates to a moisturizing composition and a skin protection product, which belong to the technical field of daily chemicals. The moisturizing composition provided by the invention mainly comprises the following raw materials in parts by weight: 1-4 parts of jania rubens extracts, 1-4 parts of hydrolyzed align, 0.5-3 parts of polygonum cuspidatum root extracts and 0.5-2 parts of gotu kola extracts. Through matching of all the raw materials, the moisturizing composition has the excellent effects of moisturizing and promotion of synthesis of collagens. In addition, the invention also provides the skin protection product containing the moisturizing composition. The skin protection product has the advantages of realizing deep and lasting moisturizing, obviously smoothing and tightening and skin and smoothing wrinkles, and the roughness and the glossiness of the skin can be improved from inside to outside in a lasting way, so that the status of the skin is improved fundamentally.

The invention discloses a tea polyphenol composite coating preservative and a preparation method thereof. The composite coating preservative is prepared from the following raw materials according to mass concentration: 2.5-5.5% of collagen, 0.5-3.5% of glycerol, 0.5-4.5% of gelatin, 0.1-1% of tea polyphenol, and deionized water. According to the preparation method, tea polyphenol, collagen, gelatin, and glycerol are used as main raw materials to prepare the composite coating preservative, and then the preservative is spread on hawthorn fruits. After 20 day's storage at room temperature, researchers research changes of hardness, vitamin C, sensory quality, weight loss rate and other indexes of hawthorn fruits, so as to evaluate the preservation effect of the composite coating preservative on hawthorn fruits. The hawthorn fruit treated by the coating preservative changes more slowly in weight loss rate, sensory quality, hardness and vitamin C than the hawthorn fruit not spread with the coating preservative. The preservative effectively prolongs the shelf life of the hawthorn fruits. The coating preservative with best preservation effect is prepared from the following raw materials: 4.0% of collagen, 3.0% of gelatin, 0.2% of tea polyphenol, and 1.0% of glycerol.

The invention relates to the technical field of solder paste, in particular to lead-free and halogen-free roll coating solder paste and a preparation method thereof. The lead-free and halogen-free roll coating solder paste comprises, by weight percentage, 82-92% of allow solder powder, 2.7-6.0% of organic solvents, 3.2-5.4% of film-forming agents, 0.5-1.8% of organic acid, 0.4-1.5% of thixotropic agents, 0.1-1.5% of surface active agents, 0.1-1.6% of preservatives, 0.5-2.0% of humectants and 0.5-2.0% of slow release agents. The lead-free and halogen-free roll coating solder paste has the advantages of being good in oxidation resistance, good in welding effect, capable of avoiding crusting during low-temperature storage, and capable of being kept wet for a long time without being dry.

The invention discloses a protein-EGCG composite nanoparticle and an antioxidant Pickering high internal phase emulsion. The preparation method of the protein-EGCG composite nanoparticle comprises thefollowing steps: 1) adding water into soybean beta-conglycinin for dispersion, and performing hydration to obtain a protein solution; 2) adding water into EGCG for dispersion to obtain an EGCG solution; 3) adding the protein solution into a polar organic solvent to denature the protein, and adding the EGCG solution to obtain a mixed solution; and 4) dialyzing the mixed solution to remove the polar organic solvent and free EGCG to obtain the protein-EGCG composite nanoparticle. The stabilizing agent in the antioxidant Pickering high internal phase emulsion disclosed by the invention is the protein-EGCG composite nanoparticle. The protein-EGCG composite nanoparticle disclosed by the invention has good biocompatibility, and a Pickering high internal phase emulsion prepared by using the protein-EGCG composite nanoparticle as a stabilizer has excellent oxidation resistance, thermal stability and storage stability.

The invention discloses plant washing liquid with disinsectization, bacteria inhibition and decontamination effects and a preparation method thereof. The plant washing liquid comprises the following components in parts by weight: 20-90 parts of soapberries, 20-90 parts of Chinese honeylocust fruits, 5-40 parts of camellia seed, 3-40 parts of cinnamomum cassia, 3-40 parts of ginger, 1-25 parts of patchouli leaves, 1-25 parts of folium artemisiae argyi, 1-25 parts of citronella leaves, 2-30 parts of daphne odera and 2-30 parts of lavender. The plant washing liquid is prepared by the 8 steps of deseeding, washing, drying, crushing, mixing, preparing an unrefined extract, preparing a refined extract and preparing a plant washing liquid finished product. The whole set of process flow is completed by adopting a physical method, the steps are simple, the cost is low, the industrial production can be formed, and the obtained plant washing liquid finished product is rich in foam, fragrant in smell, obvious in disinsectization, bacteria inhibition and decontamination effects and free from environment pollution and residue.

The invention discloses a preparation method of rosa roxburghii tratt fruit vinegar through mixed bacteria compound fermentation. The preparation method comprises the following steps: (1) preparing roxburgh rose juice: screening roxburgh roses, putting the roxburgh roses into a pulping machine for smashing, filtering and sterilizing to obtain the roxburgh rose juice; (2) dilution: adding water to dilute the roxburgh rose normal juice to obtain a roxburgh rose juice diluent; (3) adjusting sugar degree: adding white granulated sugar into the roxburgh rose juice diluent to obtain a sugar-containing roxburgh rose juice diluent; (4) alcoholic fermentation: activating yeast, inoculating the yeast into the sugar-containing roxburgh rose juice diluent, activating lactic acid bacteria, and inoculating and fermenting to obtain roxburgh rose fruit wine; and (5) acetic fermentation: activating acetic bacteria, inoculating the activated acetic bacteria into the rosa roxburghii tratt fruit wine, and fermenting to obtain the mixed bacteria composite fermented rosa roxburghii tratt fruit vinegar. The rosa roxburghii tratt fruit vinegar integrating the functions of nutrition, health care, dietary therapy and the like is prepared by jointly fermenting the rosa roxburghii tratt fruit juice with the saccharomycetes and various lactic acid bacteria, and the taste and quality of the rosa roxburghii tratt fruit vinegar are improved.
