Hot air and MeJa compounded treatment refreshing method of loquat fruit

Abstract

The invention discloses a hot air and MeJa compounded treatment refreshing method of a loquat fruit, which is specially used for protecting the picked loquat fruit from cold damage in the storage and transportation process and maintaining the quality to prolong the shelf life of the product. The technology comprises the following steps of: placing the sorted and pre-cooled loquat fruit into an airtight container with certain volume; and suffocating the loquat fruit with 15-20 micro-mol / LMeJA for 6 hours in 38 DEG C hot air. The compounded treatment refreshing method can obviously inhibit the picked loquat fruit from cold damage and quality deterioration, and the fruit subjected to the compounded treatment is not suffered from the cold damage after being stored for 35 days at 1 DEG C, while the contrast fruit which is not treated appears the obvious symptom of cold damage after being stored for 21 days. The hot air and MeJa compounded treatment refreshing method has the comprehensive advantages of separate heat treatment and separate MeJA treatment, and the used MeJA is a natural grown regulating substance in the plant, has the characteristics of no toxicity, no residues and the like, and can ensure the edible security of the fruit.

Description

1. Technical field [0001] The loquat fruit storage and fresh-keeping method of the invention belongs to the fruit and vegetable storage and fresh-keeping technology, and is specially used for the control of chilling injury and the quality maintenance of the loquat fruit during post-harvest storage and transportation. 2. Background technology [0002] Fruits and vegetables stored at low temperature will cause a series of physiological and biochemical process reactions due to the stimulation of low temperature. Different kinds of fruits and vegetables have different resistance or adaptability to these changes. Generally speaking, some fruits and vegetables produced in the tropics or subtropics, such as mango, loquat and tomato, are more prone to chilling injury. Chilling injury refers to the damage suffered by plants under the unsuitable low temperature (0-15°C) environment above the freezing point, and is a metabolic disorder and physiological disease caused by low temperatur...

AI Technical Summary

Problems solved by technology

Loquat fruit matures in the hot and rainy season in early summer. After harvesting, it is very easy to lose water, shrink, age and deteriorate at room temperature. It is also vulnerable to mechanical damage and infection by bacteria. Therefore, it is difficult to store and sell long-distance under normal conditions. high
