Embodiment 1

[0018] A cold storage method for pomegranate fruit, the steps are as follows:

[0019] (1) Picking or buying fresh pomegranates from the market, the pomegranate fruit must fall within 48 hours, and at the same time, remove deformed, non-mechanical damage, and no rotten fruits;

[0020] (2) Wash the fruit selected in the above step 1 once with light salt water, then rinse the remaining light salt water with washing, drain the water, and set aside;

[0021] The concentration of the light salt water is 3%;

[0022] (3) Disinfect the whole warehouse with quicklime in advance, and then clean it up, put the pomegranate fruit treated in step 2 into the cold storage, control the temperature at 3°C, humidity at 80°C, and keep it sealed for 6-8h After that, take it out until it returns to natural temperature;

[0023] (4) Soak the fruit treated in step 3 in the fresh-keeping liquid, keep the temperature of the fresh-keeping liquid at 20°C, soak for 15 minutes, then remove and drain th...

Abstract

The present invention discloses a cold storage method of pomegranate fruits. The method includes the following steps: picked fresh pomegranates are collected, the collected fresh pomegranates are washed and sterilized, then the sterilized pomegranates are subjected to a low temperature precooling, the precooled pomegranates are subjected to a preservative liquid treatment, and then the treated pomegranates are sent into a cold storage to conduct treatment to obtain the finished products. The beneficial effects are as follows: the method is simple and implementable, the preservation is low in costs, and the method is economical and practical, and safe and stable, provides producers and dealers a longer shelf life during transportation and sales at a normal temperature, improves the consumption period of the consumers, and has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for cold storage of pomegranate fruit. Background technique [0002] Pomegranate is a deciduous tree or shrub; simple leaves, usually opposite or clustered, without stipules, terminal or subterminal flowers, solitary or several clustered or in cymes, subbell-shaped, lobes 5-9, petals 5-9, wrinkled, imbricate arrangement; many ovules, berries spherical, with persistent calyx lobes at the top, thick peel; many seeds, berries nearly spherical, fruit ripening period September-October.
