Embodiment 1

[0049] Choose eight-ripe prunes, pick out prunes that are consistent in size, color, and shape, and have no pests and physical damage. The freezing point temperature of prunes measured by Jingchuang rc-4 temperature recorder is -3.2°C. In order to prevent prunes from being stored Freezing damage occurs during this period, and the ice temperature storage temperature is set at -2°C ± 0.2°C;

[0050] Put the prune into a moisture-proof bag and seal it, put it in a plastic basket, and put it in the ice-temperature and air-conditioned fresh-keeping warehouse by the way of overall storage, and carry out step-wise cooling. The step-wise cooling is divided into 3 stages, from room temperature to 12°C, and cooling The time is 8 hours, from 12°C to 4°C, the cooling time is 8 hours, from 4°C to ice temperature storage temperature, the cooling time is 8 hours; at the same time, the volume concentration of oxygen in the ice temperature controlled atmosphere fresh-keeping store is set to 10...

Abstract

The invention provides an ice temperature controlled atmosphere storage method for prunes, and belongs to the technical field of food storage. According to the method disclosed by the invention, modified atmosphere preservation and a near-ice-temperature technology are combined, the'ice temperature zone 'of the prunes is determined by adopting a near-ice-temperature preservation method, and ice-temperature modified atmosphere storage is carried out at a proper temperature point within the range of the ice temperature zone, so that metabolism of cell tissues of the prunes can be obviously reduced, and good original quality of the prunes can be kept; meanwhile, the controlled atmosphere fresh-keeping method is adopted, so that the prunes are always in a proper gas environment, deterioration is delayed, decay is prevented, and the purposes of storage and fresh keeping are achieved. According to the method, the quality of the prunes in the storage period can be kept, and quality deterioration such as softening, water loss and decay of the prunes can be delayed.

Description

technical field [0001] The invention relates to the technical field of food storage, in particular to a method for storing prunes under ice temperature and air conditioning. Background technique [0002] Prunes belong to the European plum species of the genus Prunus in the family Rosaceae. Its quality, color, storage and health value are higher than ordinary plums. It has the reputation of "miracle fruit" and "functional fruit". Rich in vitamins, antioxidants and dietary fiber, it also contains minerals such as iron and potassium, and does not contain fat and cholesterol. It is an indispensable product for modern people's healthy diet. Xinjiang is one of the birthplaces of prunes, and the planting area of ​​prunes in Xinjiang is increasing year by year. In recent years, Xinjiang has introduced excellent varieties of European plums, and the cultivation area has continued to expand, forming a regional large-scale production, and some varieties have entered the full fruit peri...
