Problems solved by technology

However, the traditional preservative film lacks antibacterial properties and poor safety, and needs further improvement. An antibacterial preservative film has been developed, which can kill or inhibit the microorganisms remaining on the surface of food during processing, storage and handling. Extending the shelf life and safety of food

Abstract

A fresh keeping film is prepared from, by weight, 3 parts to 4.5 parts of mannan, 0.1 part to 0.15 part of liquid paraffin, 10 parts to 25 parts of polyethylene, 4 parts to 6 parts of nanoscale Al2O3 powder, 5 parts to 10 parts of ethylene glycol distearate, 4 parts to 8 parts of vinyl siloxane, 2 parts to 7 parts of methylcellulose, 0.5 part to 0.8 part of potassium hydroxide, 1 part to 3.5 parts of rose essential oil, 3 parts to 4.5 parts of soda, 4 parts to 12 parts of alginate, 3 parts to 7 parts of nano-zinc oxide, 5 parts to 8 parts of potassium carbonate, 5 parts to 7 parts of urea-formaldehyde resin and 4 parts to 8 parts of neutral oil. The fresh keeping film has the advantages of being high in wear resistance, antibacterial property and strength, easy to store, capable of decreasing the water loss rate of freshness-retained objects, long in conservation time and free of toxin.

Description

technical field [0001] The invention relates to a fresh-keeping film. Background technique [0002] At present, the food that is given up every year due to corruption in the world exceeds the sum of the food that the United Nations provides to poor countries. In order to prolong the high freshness retention period of food and prevent food spoilage to the greatest extent, it is necessary to use plastic wrap to solve this problem. Plastic wrap can be used for food heating in microwave ovens, food preservation in refrigerators, fresh and cooked food packaging, etc. It is widely used in family life, supermarkets, hotels and restaurants, and food packaging in industrial production. Preservative film has been favored by people for its convenience, economy and attractive appearance. However, due to the general addition of plasticizers in the production process, the impact of plastic wrap on human health has also received people's attention. However, the traditional preservative ...
