Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the above-mentioned existing paper does not have the fresh-keeping characteristics of fruits and vegetables, and ordinary cartons have poor fruit and vegetable freshness, cannot effectively maintain the moisture and freshness of fruit and vegetable products, and cannot absorb the liquid that may leak out of fruits and vegetables during transportation and storage. And the harmful gases emitted (such as ethylene, etc.), can not block the penetration of external odors and other pollutants, prevent the invasion of organisms such as flies, bacteria, etc., can not improve the indoor air environment of fruit and vegetable storage, and cannot extend the preservation period and shelf life of fruits and vegetables , increase preservation costs and transportation costs, and provide a diatomite fruit and vegetable fresh-keeping paper

[0032] After 10 days of inspection, the status of bananas in ordinary cartons: 60% turned black;

[0033] After 5 days of inspection, the state of the bananas in the diatomite fruit and vegetable preservation carton: 5% turned black;

[0034] After 10 days of inspection, the state of the bananas in the diatomite fruit and vegetable preservation carton: 30% black;

[0035] Bananas in diatomite fruit and vegetable fresh-keeping cartons are 5-7 days longer than bananas in ordinary cartons;

Embodiment 3

[0037] 5 diatomite fruit and vegetable fresh-keeping cartons with a volume of 22.5cmX27.5cmX40cm, 5 ordinary cartons with the same specifications, and 0.5Kg of cucumbers in each box, at a temperature of 21-22 and a humidity of 35-40;

[0038] After 5 days of inspection, the state of cucumbers in ordinary cartons: 30% rotten;

[0039] After 10 days of inspection, the state of cucumbers in ordinary cartons: 80% rotten;

[0040] After 5 days of inspection, the status of cucumbers in diatomite fruit and vegetable preservation cartons: 5% rotten;

[0041] After 10 days of inspection, the state of the cucumber in the diatomite fruit and vegetable preservation carton: 40% rotten;

[0042] Cucumbers in diatomite fruit and vegetable fresh-keeping cartons are 4-5 days longer than those in ordinary cartons.

[0043] According to experiments, the addition of diatomaceous earth can prolong the freshness of fruits.

Abstract

The invention discloses diatomite fruit and vegetable fresh-keeping paper. The diatomite fruit and vegetable fresh-keeping paper is formed by sandwiching diatomite between two layers of paper sheets. A manufacturing method of the diatomite fruit and vegetable fresh-keeping paper comprises: spraying the diatomite on the surface of one layer of wet paper sheet and covering one layer of wet paper sheet on the diatomite; then drying to obtain the diatomite fruit and vegetable fresh-keeping paper. The method is simple; the diatomite is added into the paper sheets, and fruit fresh-keeping paper or paperboards manufactured by utilizing properties of high porosity, large specific surface area, strong adsorbability and the like of the diatomite can effectively keep moisture and freshness of fruit and vegetable products, can absorb liquid which possibly leaks out and scattered harmful gas in transportation and storage processes of fruits and vegetables, can prevent external odor and other pollutants from permeating, and can also prevent organisms including flies and insects, bacteria and the like from invading, so that an air environment in a fruit and vegetable storage room is improved, and the fresh-keeping period and the shelf life of the fruit and the vegetables are effectively prolonged.

Description

technical field [0001] The invention relates to a paper, in particular to a diatomite fruit and vegetable fresh-keeping paper. Background technique [0002] my country has abundant reserves of diatomite, with a wide geographical distribution of resources and a wide variety of varieties. Among them, the proven reserves of Changbai Mountain in Jilin Province are the largest reserves of high-quality diatomite resources discovered in China so far, and it is also one of the production areas of high-quality diatomite in the world. , but the development and utilization of diatomite resources is still in its infancy, and the research and development and application technology of diatomite paper-making products are far behind developed countries. [0003] Existing paper does not have the characteristics of fresh-keeping of fruits and vegetables, and the fresh-keeping performance of ordinary cartons of fruits and vegetables is poor. Ethylene, etc.), cannot block the penetration of ext...
