Abstract

The invention relates to a nano packing material suitable for keeping edible fungi fresh and application thereof, and belongs to the technical field of agricultural product storage and processing. The nano packing material is manufactured by the following steps of: mixing 30 percent of nano composite powder, 68 percent of linear low-density polyethylene (LLDPE) and 2 percent of coupling agent uniformly in a mass ratio at a high speed for 0.5 hour, kneading and extruding the mixture in a plasticizer, cooling the mixture for 1 to 2 hours, and granulating the mixture to obtain a nano master batch; and weighing 3.75 percent of nano master batch, 3.75 percent of antifogging agent master batch and 92.5 percent of composite plastic particles in a mass ratio, fully mixing the materials uniformly, then blowing the mixture to form a thin film, and manufacturing the nano packing material with bottom length of 40 centimeters, width of 15 centimeters and bag height of 70 centimeters. The nano material is used for packing edible fungi, forms a high-temperature low-oxygen environment, has low corrupted microbe activity and ethylene content, can effectively inhibit opening, water loss, brown stain and corruption of the edible fungi, keeps the storage quality of the picked edible fungi well, prolongs the shelf life of the edible fungi, and has broad market prospect.

Description

1. Technical field [0001] The invention relates to the preparation and application of a nano-packaging material for fresh-keeping edible fungi, belonging to the technical field of storage and processing of agricultural products. 2. Background technology [0002] In recent years, with the transformation of food research from nutritional traditional foods to physiologically regulating functional foods, plant-based functional foods have received more and more attention. Fresh edible fungi are rich in protein and 8 kinds of essential amino acids, which are beneficial to human health and have anti-cancer effects. They are increasingly favored and are known as hygienic food in the 21st century. The production of edible fungi in my country has developed rapidly and has become the world's largest producer and exporter of edible fungi. Edible fungus products have become one of the main commodities for exporting agricultural and sideline products in my country. However, due to the hi...
