Problems solved by technology

[0003] Figs are easy to soften, brown, lose flavor and rot after harvesting. They can only be stored for 1-2 days under normal temperature conditions. The freshness period is extremely short and it is difficult to transport and sell over long distances.
Studies have shown that the main cause of fig fruit rot is due to the high sugar content, high water content, imperfect peel protection function of fig fruit, and the peel is easily damaged and infected by microorganisms.

Abstract

The invention discloses a method for prolonging the storage period of figs by using controlled atmosphere. The method for prolonging the storage period of figs by using controlled atmosphere packaging is characterized in that healthy, damage-free, pest-free and eight-mature figs are pre-cooled, and then are stored in a cold store with controlled atmosphere environment with the oxygen concentration of 3-5% and the carbon dioxide concentration of 19-21%. The high-carbon dioxide and low-oxygen controlled atmosphere packaging and storage of the figs can reduce the breathing intensity of fruits, inhibit decaying of the fruits and maintain the hardness and the original color of the fruits, and can also alleviate nutrition loss and maintain good quality characteristics.

Description

technical field [0001] The invention belongs to the technical field of food processing and preservation, and relates to a method for prolonging the storage period of figs by using controlled atmosphere. Background technique [0002] Fig (Ficus carica) belongs to the perennial subtropical deciduous fruit tree of Moraceae (Moraceae) Ficus (Ficus L.). Shandong, Jiangsu and other places. Figs are sweet in taste, soft in texture, and rich in minerals, dietary fiber, free amino acids, vitamins, and organic acids, among which some organic acids, phenolic compounds, vitamin E, and carotenoids can scavenge free radicals. Therefore, figs have high nutritional and medicinal value, not only can eliminate fatigue, promote the recovery of the body's physical strength, but also have anti-cancer and anti-tumor effects. [0003] Figs are easy to soften, brown, lose flavor and rot after harvesting. They can only be stored for 1 to 2 days under normal temperature conditions. Studies have sh...
