Embodiment 1
[0031] The preparation of spinning solution is as follows:
[0032] Take ε-polylysine powder to make a mother solution with a concentration of 0.1mg / ml, and prepare a 1-9mg / ml polylysine solution from the ε-polylysine mother solution, with a mass-volume ratio of 0.1%-0.9% Tea polyphenols, gelatin with a mass volume ratio of 15% to 18%, acetic acid with a volume fraction of 88%, and distilled water with a volume fraction of 12% were mixed and placed in a glass container, and a magnetic stirrer was added, and the solution was placed at room temperature. Stir on a magnetic stirrer for 3-5 hours until it is completely dissolved. After stirring, take it off and let it stand for 10-25 minutes until the solution matures and stabilizes.
[0033] The electrospinning process is as follows:
[0034] Step 1: Adjust the ambient temperature and humidity in the operating room to ensure that the spinning environment temperature is 20°C to 30°C and the humidity is within the range of 40% to 6...

The invention relates to the technical field of biological nano-materials, in particular to a preparation method of an edible antibacterial anti-oxidative loaded nano-fiber membrane, and provides a preparation method of the edible antibacterial anti-oxidative loaded nano-fiber membrane. The method includes the steps: mixing and stirring tea polyphenol, epsilon-polylysine and gelatin until the materials are completely dissolved to obtain spinning solution; performing electrostatic spinning on the spinning solution, and heating and crosslinking electrostatic spinning products to obtain the edible antibacterial anti-oxidative loaded nano-fiber membrane. The proportion of the tea polyphenol, the epsilon-polylysine and the gelatin in the edible antibacterial anti-oxidative loaded nano-fiber membrane is (0.1-0.9):(0.1-0.9):(15-18). The preparation method of the edible antibacterial anti-oxidative loaded nano-fiber membrane solves the technical problems that an existing natural packaging material cannot give consideration to bacteriostatic activity and antioxidant activity.
Description
technical field [0001] The invention relates to the technical field of biological nanomaterials, in particular to a preparation method of an edible antibacterial and anti-oxidation loaded nanofiber membrane. Background technique [0002] Food packaging is very important for food storage and food safety, which is not limited to the problem of food itself, but also related to the packaging materials and products in direct contact with food. However, most of the traditional plastic packaging materials come from petroleum. In the process of plastic production, in order to improve its mechanical and optical properties, some chemical additives are often added, such as plasticizers, fluorescent whitening agents, ultraviolet absorbers, and flame retardants. Wait. Chemical additives can, under certain conditions, migrate from polymeric materials to foods that come into direct contact with them, thereby endangering human health. In addition, the non-degradability of traditional plas...
