The invention belongs to the technical field of microorganisms, and particularly discloses a strain of lactobacillus plantarum and application thereof, and the preservation number of the lactobacillus plantarum SN21 is CCTCC (China Center For Type Culture Collection) NO: M20252076. The lactobacillus plantarum SN21 provided by the invention is applied to fermentation of the peanut protein, the antigenicity of the peanut protein can be effectively reduced by optimizing fermentation conditions, and the oxidation resistance of a product is improved; meanwhile, the lactobacillus plantarum SN21 provided by the invention is used for fermenting peanut protein, and the solubility and the emulsifying property of the lactobacillus plantarum SN21 are improved. The strain has a good application prospect in development and utilization of fermented foods, and particularly has a relatively good application value in development of low-sensitivity peanut products and improvement of functional characteristics.

The invention discloses a method for preparing low-sensitization protein peptide through microwave combined enzymolysis composite modification and application, and relates to the technical field of food processing. The treatment method comprises the following steps: preparing protein powder into a solution, adding tea polyphenol into the solution, and uniformly mixing to prepare a protein solution; carrying out microwave modification treatment on the protein solution; adding compound protease into the protein solution subjected to microwave treatment for enzymolysis and enzyme deactivation; and filtering the enzymolysis product, and drying the filtrate to obtain the low-sensitization protein peptide. According to the method, microwave and enzymolysis combined composite modification is adopted, so that the sensitization of protein can be reduced, the reaction time is shortened, and the method is simple in process, free of pollution and high in safety. In the enzymolysis process, active peptide substances which are easy to digest and absorb, can enhance immunity and delay senescence are synchronously generated, and tea polyphenol added in the formula can synergistically relieve anaphylactic reaction and play an anti-oxidation role, so that multi-element synergy of desensitization, function enhancement and flavor optimization is realized, and the added value and market application potential of the product are improved.

This utility model relates to the field of food processing technology and discloses a magnetic field treatment device for improving protein emulsification properties and reducing protein allergenicity. The device includes: a sample bottle, a circulating water pump, and a magnetic field generating mechanism connected in a sequential cycle. The sample bottle has an inlet pipe and an outlet pipe. The circulating water pump is connected to the sample bottle through the inlet pipe, and the magnetic field generating mechanism is connected to the sample bottle through the outlet pipe. This utility model, by setting up a sample bottle, a circulating water pump, and a magnetic field generating mechanism connected in a sequential cycle, simultaneously achieves the circulating transport of protein liquid and uniformly treats the protein liquid with a magnetic field to generate Lorentz force. It is simple and practical, and can effectively improve protein emulsification properties and reduce protein allergenicity.

The invention belongs to the technical field of functional dressings, and discloses a liquid dressing for skin repair as well as a preparation method and application thereof, the liquid dressing for skin repair is prepared from the following raw materials in percentage by weight: 1-5% of zinc hyaluronate, 2-10% of giant salamander collagen, 1-8% of aloe polysaccharide, 0.5-6% of L-lactic acid, 0.5-2% of carbomer, 0.1-0.5% of preservative, 0.1-2% of pH regulator and the balance of purified water. The components of the dressing are reasonably proportioned and synergistically gained, and the dressing has the effects of resisting bacteria, resisting oxidation, promoting angiogenesis and the like, can effectively promote skin wound repair, and also has good safety and use comfort.
