Problems solved by technology

During the harvest season of pomegranates, a large number of pomegranates cannot be sold in time after harvesting, which will easily cause serious water shortage or rot in the pomegranates, causing great economic losses to the fruit farmers. It can be stored for 3~4 months, and the intact rate is about 90%

Embodiment 1

[0016] A storage and preservation method for pomegranate, comprising the following steps:

[0017] (1) Cooling: Immediately after harvesting the pomegranate, put it in a warehouse at 8-10°C, and let it stand to cool down, which can inhibit the reproduction of diseases and insect pests, weaken the respiration of pomegranate, reduce the nutrient consumption of pomegranate, prolong the storage time of pomegranate, and obtain cooling pomegranate;

[0018] (2) Freezing: Put the cooled pomegranate in a freeze dryer, freeze-dry until the water content is reduced by 3-4%, kill the residual pests in the pomegranate, make the pomegranate lose a small amount of water, remove the residual gas in the pomegranate, and inhibit the pomegranate. Respiration, retain the nutritional content of pomegranate, prolong the shelf life of pomegranate, get frozen pomegranate;

[0019] (3) Preservation: Spray the preservative evenly on the frozen pomegranate and let it dry to form a protective layer on t...

Abstract

The invention mainly relates to the technical field of fresh-keeping, and discloses a storage and fresh-keeping method of pomegranates. The method comprises the following steps of cooling, freezing, fresh keeping and storing. The method is simple and convenient to operate. With the method, the fresh-keeping time of the pomegranates is prolonged to 6 months, and a perfectness ratio is 95.3 percent,and the storage fresh-keeping effect of the pomegranates is obviously improved, and the transportation and storage cost of the pomegranates is reduced, and the pomegranates can be across the season,and the economic income of planting farmer is improved. When the pomegranates are picked, the pomegranates are placed in a warehouse for cooling so as to inhibit the reproduction of diseases and pests, reduce the respiration of the pomegranates, reduce the nutrition consumption of the pomegranates, and prolong the storage time of the pomegranates. After cooling, the pomegranates are subjected to freeze-drying so as to kill the residual disease worms in the pomegranates, enable the pomegranates to lose a small amount of water, remove residual gas in the pomegranates, inhibit the respiration ofthe pomegranates, reserve the nutrient content of the pomegranates, and prolong the shelf life of the pomegranates.

Description

technical field [0001] The invention mainly relates to the field of fresh-keeping technology, in particular to a storage and fresh-keeping method of pomegranate. Background technique [0002] Pomegranate is a treasure for the whole body. Pomegranate seeds are rich in organic acids, sugars, proteins, fats, vitamins and minerals, which can promote gastrointestinal function, protect cardiovascular and cerebrovascular, relieve alcohol poisoning, relieve fatigue, and prolong life; according to relevant experiments, Pomegranate peel can astringe intestinal mucosa and effectively treat diarrhea, dysentery and other diseases. Pomegranate peel contains alkaline substances that have the effect of repelling insects; pomegranate flowers and leaves can stop bleeding, soaking eyes and washing eyes can improve eyesight. During the harvest season of pomegranates, a large number of pomegranates cannot be sold in time after harvesting, which will easily cause serious water shortage or rot in ...
