Abstract

The method provides a storage method for fruit fresh-keeping, and belongs to the technical field of agricultural and forestry crop storage. The method of the invention comprises the following steps: step one, after picking fruit, quickly soaking the fruit in salt water for 15-25 minutes, the concentration of the salt water being 15%-23%, and conducting drying by cold air after the soaking is completed; step two, irradiating the dried fruit with ultraviolet rays, and spraying atomized emulsion with an ultrasonic atomizer on the surface after 5 minutes of irradiation; step three, placing the fruit in a sealed bag, and filling the sealed bag with mixed gas; and step four, conducting preservation in a cold storage after sealing, keeping the temperature at 1-2 DEG C, and keeping the humidity at85%-95%. The fruit storage time can be effectively extended by the fruit storage method of the present invention, the fruit can be kept fresh more than 90 days, the flavor and moisture of the fruit can be maintained without loss, and the shelf life is greatly extended.

Description

technical field [0001] The invention relates to agricultural product preservation technology, in particular to a fruit preservation and storage method, which belongs to the technical field of agricultural and forestry crop storage. Background technique [0002] Summer is the season when many fruits are ripe and harvested. However, in the hot summer season, fruits often suffer from diseases after harvesting in a short period of time, and are very prone to mold, rot and spoilage. It is extremely difficult to protect, store and transport, and the postharvest loss is serious, which greatly reduces the edible quality of stored fruits. Economic value and health security. At the same time, if a large amount of fruit floods into the market in a short period of time, its price will often drop sharply, impacting the local market. [0003] In recent years, with the improvement of people's requirements for food freshness and food safety and the diversity of sales methods, especially t...
