Dual controlled release fruits and vegetables fresh-keeping paper and manufacturing method thereof

Abstract

A double controllable releasing fruit and vegetable fresh-keep paper consists of three layers of paper-plastics composite materials or two layers of paper-plastics composite materials and a layer of base paper and two kinds of different controllable releasing preservatives, wherein, the different preservatives are respectively arranged in the centers of two sandwiches formed by the three layers of paper-plastics composite materials or the two layers of paper-plastics composite materials and the layer of base paper, and the preservatives in the sandwiches are distributed in a discontinuous grid shape. The aim of creating an optimum anticorrosion sterilization storage preservation environment can be achieved by selecting species of effective components of preservatives, changing a speed of controlling and releasing the formulas of the preservatives, adjusting indexes of ventilating and moisture permeability of the fresh-keep paper structure material, thereby greatly prolonging the transporting preservation period of a preserved product and improving the quality of the product, and improving economic benefit of transportation and preservation. The controllable releasing fruit and vegetable fresh-keep paper can fulfill transportation and preservation requirements of most varieties of the prior fruits and vegetables through omnidirectional and multivariate regulation, and provides very high application value in static preservation.

Description

technical field [0001] The invention belongs to the field of fresh-keeping of agricultural products, in particular to a double-controllable-release fruit and vegetable fresh-keeping paper and a manufacturing method thereof. Background technique [0002] In the process of transportation and preservation of fruits and vegetables, the use of appropriate antiseptics to inhibit the reproduction of microorganisms after harvesting fruits and vegetables, so as to prolong the storage and transportation period of fruits and vegetables and better maintain the original flavor and freshness of fruits and vegetables is currently used in fruit and vegetable storage. An important technical measure in the field of transportation and preservation. In recent years, with the adjustment of the planting structure of fruits and vegetables, the formation of regionalization and large-scale production models of varieties, the mutual transportation and circulation of fruits and vegetables between regi...

Problems solved by technology

At present, the fruit and vegetable preservatives used at home and abroad all adopt the technology of adjusting the formulation and dosage form of the agent to realize the regulation of the release rate, and have never involved the use of performance indicators of composite materials and base paper to achieve the purpose of regulating the release rate. Moreover, domestic Most of the fresh-keeping papers also use the application method of sandwiching a layer of fresh-keeping agents in the middle of the two-layer packaging material. The types of active ingredients of the fresh-keeping agents used are very few, the release method is single, and the application range is narrow, which cannot meet different transportation deadlines, different transportation conditions and affected areas. Anti-corrosion and fresh-keeping requirements for transported products affected by different origins, seasons, varieties and complex and changeable pre-harvest factors
