The application discloses a kind of plant polyphenol and maleic anhydride copolymer modified polyester and its preparation method, the modified polyester includes polyester, plant polyphenol and maleic anhydride copolymer.The preparation method includes that the plant polyphenol and maleic anhydride copolymer are dissolved in organic solvent, catalyst is added and mixed uniformly, and reaction liquid is obtained;The reaction liquid is heated to 25-80 DEG C, and is reacted under the condition of stirring for 4-16h, is cooled to room temperature, then is added in petroleum ether or ethyl acetate, and solid precipitate is separated out;Solid precipitate is filtered out and is washed with ethanol, and is dried, and antibacterial and antioxidant functional modified material is obtained;Antibacterial and antioxidant functional modified material is mixed with the polyester and is placed in high mixer, and is extruded again, and the modified polyester is obtained.The modified polyester material has the characteristics of good antibacterial and antioxidant performance, good processing performance, good tensile strength and toughness.

The present application relates to the technical fields of genetic engineering and biological agents, and particularly relates to a hybrid peptide with immunoregulation and antioxidant functions, and a preparation method and application thereof.The polypeptide provided by the present application has both immunoregulation and antioxidant functions, and can significantly improve the immune function of the body and reduce the damage caused by immunosuppression to the body in normal or immunosuppressed states; and can enhance the antioxidant capacity of cells and the body; meanwhile, the polypeptide has the advantages of low cytotoxicity, high safety, simple preparation, low cost, and can be used as an ideal immunoregulator and antioxidant, and can be widely used in the fields of medicine, food, health care, feed, nutrition and the like of humans and animals, and has good application potential and value.

This invention belongs to the field of functional probiotic screening and application technology, specifically involving a novel strain of *Lactobacillus plantarum* (…). Lactiplantibacillus plantarum The *Lactobacillus plantarum* strain was deposited on January 15, 2026, at the China Center for Type Culture Collection (CCTCC), Wuhan University, Wuhan, China, with accession number CCTCC NO: M202026133. This strain exhibits strong antioxidant capacity, significant inhibitory and flocculating effects against hemolytic streptococci, and can significantly reduce the levels of pro-inflammatory cytokines IL-6 and IL-1β induced by hemolytic streptococci while increasing the level of the anti-inflammatory cytokine IL-22. It has no toxic effects on the body, good safety profile, and can be used to prevent colonic polyps and colon cancer caused by hemolytic streptococci, showing broad application prospects.

The invention relates to the technical field of food fresh keeping, and particularly discloses a composition with an antibacterial function, a preparation method and application in fresh keeping of hot fresh meat, the preparation method comprises the following steps: (S01) taking lactobacillus plantarum, lactobacillus reuteri and fructo-oligosaccharide, mixing, stirring, setting constant temperature, and adjusting humidity to obtain an antibacterial matrix; (S02) mixing sodium alginate with the bacteriostatic substrate, stirring, and adjusting the pH value to obtain a bacteriostatic structure substrate; (S03) adding a grape seed extract, adjusting the stirring speed and duration, measuring the concentration data of each component, and testing the solubility to obtain a functional antibacterial component; and (S04) adopting principal component analysis, gradually adjusting the proportion of each component, judging the influence of different proportions on bacterial colony inhibition by monitoring and analyzing the number of bacterial colonies and the inhibition rate, and obtaining an optimal proportion combination according to experimental data to obtain a preparation scheme of the composition with the antibacterial function. The invention has the characteristics of being beneficial to maintaining the health and balance of intestinal microecology, good in safety and better in stability.
