Problems solved by technology

Inorganic antibacterial agents have the advantages of good heat resistance, wide antibacterial range, and no drug resistance. Synthetic antibacterial agents mainly have fast sterilization speed and good antifungal effect. However, both inorganic antibacterial agents and synthetic antibacterial agents have food safety problems. However, natural antibacterial agents have good biocompatibility and environmental performance, are less toxic, and do not have food safety hazards; therefore, the development and application of natural antibacterial agents has received more and more attention.
At present, the most commonly used natural antibacterial agent for the preparation of natural antibacterial films is chitosan, but the antibacterial properties of chitosan are affected by the preparation conditions, and often cannot achieve good antibacterial activity.

Embodiment 1

[0018] Weigh 3 g collagen and dissolve it with 30 ml distilled water at 45°C to make collagen aqueous solution; weigh 1 g chitosan and dissolve it with 30 ml 1.5% (v / v) acetic acid solution at 60°C to make chitosan Sugar solution; ultrasonically dissolve 4 ml of oregano essential oil in 40 ml of distilled water containing 0.25 g of soybean lecithin to make oregano oil solution, then mix the three solutions, add 1.0 g of glycerin as a plasticizer, stir well, Let stand for 30 minutes to degas, and keep warm at 45°C. Pipette 6 ml of casting solution each time and spread it on a plexiglass frame of 120 mm×80 mm×2 mm to form a film. The film-forming temperature is 22°C and the film-forming time is 24 h. The collagen antibacterial film can be obtained. The antibacterial activity of the membrane was measured by the filter paper method, and the membrane was cut into a circle of 12 mm to investigate the antibacterial effect of the antibacterial membrane on Escherichia coli and Staphyl...

Embodiment 2

[0020] Weigh 1 g of collagen and dissolve it with 30 ml of distilled water at 45°C to make a collagen aqueous solution; weigh 3 g of chitosan and dissolve it with 30 ml of 1.5% (v / v) acetic acid solution at 60°C to make chitosan Sugar solution; ultrasonically dissolve 5 ml of clove essential oil in 40 ml of distilled water containing 0.25 g of soybean lecithin to make oregano oil solution, then mix the three solutions, add 1.6 g of glycerin as a plasticizer, stir evenly, and statically Set for 30 min to degas and keep warm at 45°C. Pipette 6 ml of the casting solution each time and spread it on a plexiglass frame of 120 mm×80 mm×2 mm to form a film. The film-forming temperature is 4°C and the film-forming time is 4 h. The collagen antibacterial film can be obtained. The antibacterial activity of the membrane was measured by the filter paper method, and the membrane was cut into a circle of 12 mm to investigate the antibacterial effect of the antibacterial membrane on Escheric...

Embodiment 3

[0022] Weighed 4 g of collagen and dissolved it with 30 ml of distilled water at 45 °C to make a collagen aqueous solution; ultrasonically dissolved 3 ml of cinnamon essential oil in 40 ml of distilled water containing 0.25 g of soybean lecithin to make an oregano oil solution, and then The three solutions were mixed, 0.4 g of glycerin was added as a plasticizer, stirred evenly, left to stand for 30 min to degas, and kept at 45°C. Pipette 6 ml of the casting solution each time and spread it on a plexiglass frame of 120 mm×80 mm×2 mm to form a film. The film-forming temperature is 30°C and the film-forming time is 24 h. The collagen antibacterial film can be obtained. The thickness, mechanical properties, elongation at break, light transmittance at 600 nm and water vapor transmission rate of the prepared antibacterial film were measured, and the results are shown in Table 1.

Abstract

The invention discloses an edible fishskin collagen antibiosis membrane and a preparing method thereof, wherein fishskin collagen, chitosan, plant essential oil, soya bean lecithin and glycerol are contained in component of the membrane. The preparing method includes: firstly dissolving the fishskin collagen powder in distilled water to prepare fishskin collagen solution, dissolving the chitosan in chitosan solution prepared by acetic acid solution, dissolving the plant essential oil in distilled water of the soya bean lecithin to prepare plant essential oil solution, mixing the three solutions, adding in the glycerol as the plasticizer, evenly stirring, standing for degassing, and removing and spreading the obtained solution on an organic glass framework for drying to obtain the membrane. The edible fishskin collagen antibiosis membrane has good antibiosis performance, can be biodegraded, causes no pollution to the environment, can restrain growing of microorganisms on the surface of food and accordingly has the effect of food refreshment and shelf life extending.

Description

technical field [0001] The invention relates to an edible fish skin collagen antibacterial film and a preparation method thereof, belonging to the application technical field of antibacterial packaging films. Background technique [0002] In recent years, with the enhancement of environmental awareness, people pay more and more attention to the environmental pollution and food safety problems caused by plastic packaging materials, and have higher requirements for food packaging materials. Therefore, edible packaging films prepared from natural biological materials have received great attention. Edible film refers to a dense film with a porous network structure formed by the interaction of different molecules using natural edible substances (such as polysaccharides, proteins, lipids, etc.) as raw materials, which can be used for food packaging and fresh-keeping, etc. aspect. Some antibacterial agents can be added to the edible film to improve the antibacterial performance o...
