Package suitable for storing and refreshing fig and application thereof to storage and refreshment

Abstract

The invention relates to a package suitable for storing and refreshing fig and application thereof to storage and refreshment. A packaging film bag is made of polyethylene (PE) or polyvinyl chloride (PVC) with specific ventilation property, and can adjust the concentration of oxygen and carbon dioxide in the packaging bag and control the concentration of the oxygen in the package to be 2 to 5 percent and the concentration of the carbon dioxide in the package to be 15 to 20 percent. A using method comprises the following steps of: harmlessly harvesting fruit and vegetable in due time, filling into a box lined with a refreshing film bag, fully precooling an opening, putting into an air conditioning packaging film bag, tying the opening, and stacking for storing and refreshing. By the package, the quality can be well kept, rot caused by pathogenic bacteria is avoided, and the refreshment time and the market circulating distance are obviously prolonged in the process of storing and refreshing the fig and in the whole logistics process. Through tests, the fig can be refrigerated and refreshed for 20 to 30 days when standard technical operation conditions are met.

Description

Technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products in agricultural engineering. In particular, it relates to a packaging suitable for storage and preservation of figs and its application in storage and preservation. Background technique [0002] Figs are among the "treasures" of our country's fruits. The reason why figs are so popular is that figs have high nutritional value and are called "big tonic products". Figs contain carbohydrates as high as 74.3%, ranking first among fruits. They contain 15-20% sugar and only 18-20% water content. Although they are fruits, there is not much "water" and they are rich in vitamins A and C. Nutrients have the functions of producing body fluids, appetizing, and stopping diarrhea. They are also indispensable medicinal materials in Uyghur medicine. [0003] Figs are extremely easy to soften, brown, and decay after being picked. They can only be stored for 1 to 2 days under nor...

AI Technical Summary

Problems solved by technology

However, at present, the application effect of fruit and vegetable plastic wrap in fruit and vegetable products that require high carbon dioxide is not very obvious. Low, causing anaerobic respiration and hypoxic injury

According to the existing production technology level, it is difficult to produce an optional breathable packaging film that can generate 15% to 20% carbon dioxide concentration in fruit and vegetable packaging and maintain a certain oxygen content (2% to 5%)

[0005] Generally speaking, there is no scientific and complete technical method and supporting products suitable for fig fresh-keeping
