Embodiment 1

[0032] Taking Qinguang No. 2 nectarine as an example, a polyethylene film with a thickness of 0.03mm and a porosity of 15‰ was used in the comparison test at 0±0.5°C, 1±0.5°C, 3±0.5°C and 5±0.5°C. Storage effects of bag-sealed nectarine fruit.

[0033] The result is as follows:

[0034] After being stored at 0±0.5°C for 30 days, mild chilling injury symptoms appeared, manifested as browning of the pericarp.

[0035] Nectarine fruits stored at 1±0.5℃ did not show symptoms of chilling injury, and the fruit quality was good.

[0036] Nectarine fruits stored at 3±0.5℃ and 5±0.5℃ showed symptoms of chilling damage in different degrees, which manifested as flocculation and lignification of pulp texture.

[0037] Among them, the fruit stored at 5±0.5℃ for 20 days will appear serious symptoms of chilling injury.

[0038] This example 1 shows that the storage characteristics of nectarine fruit are significantly different under different refrigeration temperatures; according to the e...

Embodiment 2

[0040] Taking Qinguang No. 2 nectarine as an example, choose a medium-sized fruit with straight fruit, uniform maturity, good development, and no mechanical damage.

[0041] Divided into three groups:

[0042] The first group was put into polyethylene film packaging bags with a thickness of 0.03mm and a porosity of 5‰, and stored in a mechanical cold storage with a temperature controlled at 1±0.5°C and a relative humidity of about 90%.

[0043] The second group was put into polyethylene film packaging bags with a thickness of 0.05mm and a porosity of 5‰, and stored in a mechanical refrigerator with a temperature controlled at 1±0.5°C and a relative humidity of about 90%.

[0044] The third group was put into polyethylene film packaging bags with a thickness of 0.07mm and a porosity of 5‰, and stored in a mechanical refrigerator with a temperature controlled at 1±0.5°C and a relative humidity of about 90%.

[0051] The first group was put into polyethylene film packaging bags with a thickness of 0.03mm and a porosity of 15‰, and stored in a mechanical cold storage with a temperature controlled at 1±0.5°C and a relative humidity of about 90%.

[0052] The second group was put into polyethylene film packaging bags with a thickness of 0.05mm and a porosity of 15‰, and stored in a mechanical refrigerator with a temperature controlled at 1±0.5°C and a relative humidity of about 90%.

[0053] The third group was put into polyethylene film packaging bags with a thickness of 0.07mm and a porosity of 15‰, and stored in a mechanical refrigerator with a temperature controlled at 1±0.5°C and a relative humidity of about 90%.

Abstract

A method for storing the nectarine fruits includes such steps as screening, physical sterilizing, pre-cooling, loading in sealed bags, and cold storage.

Description

technical field [0001] The invention belongs to a fruit storage method, in particular to a nectarine fruit storage method. technical background [0002] The fresh nectarine fruit is attractive in aroma, delicious in texture and rich in nutrition, and is favored by consumers. However, fresh nectarine fruits in my country mature in high temperature and rainy seasons, and are easy to soften and rot after picking, and are not resistant to storage. Therefore, how to control fruit softening and keep the fresh and crisp pulp texture of nectarine fruits has become an urgent problem to be solved. [0003] At present, low-temperature storage is one of the most effective methods for storage and preservation of horticultural products, and the existing nectarines basically adopt low-temperature storage. It is generally believed that low temperature is beneficial to the storage of nectarine fruit, and cold storage can effectively reduce rot and prolong the preservation period appropriate...
