The invention discloses a water-soluble compound antibacterial agent and its preparation method. Antibacterial active ingredients of the water-soluble compound antibacterial agent are composed of a garlic extract product, a cordate houttuynia extract product, a tarragon extract product, a chrysanthemum extract product, a folium eriobotryae extract product, a lophatherum gracile extract product and a folium cortex eucommiae extract product. Garlic, cordate houttuynia, tarragon, chrysanthemum, folium eriobotryae, lophatherum gracile and folium cortex eucommiae which have different degrees of inhibiting effects on bacteria, mould and yeast are used as raw materials to be mixed so as to prepare the antibacterial agent. Thus, antimicrobial spectrum of the antibacterial agent is broadened effectively, and the defect that current plant antibacterial agents are prepared by using a single plant as a raw material and have poor broad-spectrum antibacterial effect is overcome. The antibacterial agent can inhibit a wide range of bacteria and has better effects. The invention also discloses a preparation method of the water-soluble compound antibacterial agent.

The invention discloses a method for improving the comprehensive quality of the shelf life of leisure products of middle fat fresh water fish, which belongs to the field of the processing of aquatic products. A processing technology of fresh water fish leisure food, namely fish tidbit mainly comprises two steps: (1) fresh fish is dissected and washed, pickled, rinsed, dried, fermented, chopped and broken down, made into a fish raw material, and preserved in a cold storage warehouse; and (2) a fish tidbit raw material is desalted, dried, granulated, baked, seasoned, antiseptic and vacuum packaged, sterilized, and inspected, and enters an air conditioning room. The method ensures that the quality of a product keeps well by controlling the reduction of the desalination temperature and the prolonging of the desalination time in the desalination process; the method adopts a low temperature heat pump to dry, saves energy consumption, and uses a novel preservative; the method achieves the aim of controlling the total number of coliforms and colonies by compounding nipagin ester and butyl paraben and adopting a normal-pressure cooking sterilization method; at the same time, the method hassmall loss of nutrient contents, the overall sensory quality of the product keeps good characteristics, finally the aim of prolonging the shelf life of a fish tidbit product is achieved, and the shelf life reaches more than 12 months.

Belonging to the technical field of disinfection, the invention discloses a skin disinfection gel to solve the disadvantages of existing disinfection technologies, especially preoperative disinfection technologies. The skin disinfection gel is composed of the following active components by mass: 1.5%-6% of chitosan, 1.5-10% of chitosan oligosaccharide, 2%-8% of baicalin, 0.5%-2% of chlorhexidine, 0.5%-1.5% of sodium alginate, 2%-5% of agarose, and 1.5%-5% of a mint extract. And the disinfection effect is good. The disinfection gel disclosed in the invention can be used for hand disinfection or skin disinfection in sanitary disinfection or preoperative disinfection, and with excellent disinfection effects and lasting function, it has very good application prospects and economic benefits.

The present invention discloses an anticorrosion and preservation compound preparation. The compound preparation comprises the following components in parts by weight: 1-5 parts of epsilon-polylysine, 1-5 parts of butylparaben and 0.2-0.8 part of rosemary essence oil, 5-20 parts of chitooligosaccharides and 1-5 parts of EDTA disodium. The present invention also discloses an application of the anticorrosion and preservation compound preparation in the anticorrosion of low-temperature meat products. Compared with the prior art, the compound preparation is simple in preparation, very good in the thermal stability, and favorable for heat treatment of prodcuts before leaving the factory, reduces the number of initial bacteria when leaving the factory and prolongs the shelf life of the products. In addition, the compound preparation is convenient in use and wide in application range, and has great practical significances to expand the bacterium inhibition spectrum, exert the best effects and conform to the development trend of food additives.
