Abstract

The invention provides a bacteriostasis, shockproof and moisture-absorbing degradable food fresh-keeping mat and a preparation method thereof. The preparation method of the antibacterial, shockproof and moisture-absorbing degradable food preservation mat comprises spraying a natural antibacterial agent on the surface of the antibacterial PLA / starch foaming material, and then coating the antibacterial PLA / starch foaming material with a perforated polylactic acid film , that is. The fresh-keeping pad provided by the invention has dual antibacterial effects inside and outside, the internal antibacterial agent is released slowly, and the external antibacterial agent quickly plays a role through volatilization or contact with food, taking into account the timeliness and long-term effect of antibacterial, and has broad-spectrum antibacterial ability, not only It can inhibit the reproduction of microorganisms, reduce food spoilage, prolong the storage period of products, and has certain water absorption and shock resistance to ensure product quality; at the same time, the fresh-keeping mat provided by the invention is a green, safe and environment-friendly all-biological Degradable materials have very broad application prospects.

Description

technical field

[0001] The invention belongs to the technical field of foamed plastics, and in particular relates to a degradable food fresh-keeping pad with antibacterial, shockproof and moisture absorption properties and a preparation method thereof. Background technique

[0002] At present, my country's logistics and transportation system is not perfect, and the fresh-keeping technology applied to the market is relatively simple. The contradiction between the ever-increasing production of fresh food and insufficient, unsupported and imperfect fresh-keeping techniques has gradually become prominent. Taking pork as an example, the "Analysis of China's Pork Circulation Loss" released by the Ministry of Agriculture shows that the loss rates of pork in the three links of storage, transportation and sales are 3.98%, 0.24% and 1.46% respectively; 1 billion tons, but the loss rate is close to 20%, which is five times that of developed countries. The output value of fruit and veg...
