Embodiment l

[0028]Embodiment 1, the sweet cherry that is harvested in batches in due course is packed into the carton that is lined with MA storage fresh-keeping bag, and the specification of carton is long 47cm, wide 32cm, high 12cm, each long 48cm, wide 32cm, the standard plastic of high 26cm The turnover box can hold two boxes of cherries, and the mass of each box of cherries is 10.0kg. The specifications of the MA fresh-keeping bag designed according to the regression equation are 86cm in length, 65cm in width and 0.004cm in thickness. Put the cherries into a carton lined with a modified atmosphere storage bag, transport them to the storage, and pre-cool them in a constant temperature room at 0±1°C. The pre-cooling time is more than 24 hours, and the product temperature drops to 0±1°C. The bag is sealed, and it is directly transported with MA packaging for long-distance transportation, and then enters the sales channel with MA packaging, and then enters the consumer’s home with MA pac...

Embodiment 2

[0029] Embodiment 2, the sweet cherry that is harvested in batches in due course is packed into the carton that is lined with MA nanometer fresh-keeping bag, and the specification of carton is long 16cm, wide 16cm, high 18cm, then carton packing inner diameter is long 48cm, wide 32cm, In a standard plastic turnover box with a height of 26cm, each plastic box can hold 6 cartons, and each box can hold 3.0kg of cherries. According to the regression equation, the specifications of the MA nano storage bag are 45cm in length, 32cm in width and 0.0027cm in thickness. After the sweet cherries are transported to the cold storage, they are pre-cooled at a temperature of 0±1°C for 24 hours. When the product temperature drops to 0±1°C, the mouth of the bag is tightly tied and stored in a cold storage at 0±1°C. Temperature, humidity and gas detection were carried out during storage, and the CO in the bag 2 5-8%, O 2 It is 4-8%; the sweet cherries after storage are directly transporte...

Embodiment 3

[0030] Example 3, sweet cherries are treated with pre-harvest calcium, which is sprayed twice with 0.5% CaCl2.2H20 solution at the flower bud stage and full bloom stage of cherries; The post-calcium treatment is to soak the cherries with 1.0% calcium gluconate for 10min under a vacuum pressure of 0.2×105Pa after harvesting; put the calcium-treated sweet cherries directly into plastic turnover boxes, and then transport them to CA mechanically controlled atmosphere Long-term storage in the warehouse. Before leaving the warehouse, put them into MA fresh-keeping bags, tie the bags and seal them, and transport them directly with MA packaging. Formed a modified atmosphere logistics chain consisting of harvesting-CA storage-MA transportation-MA sales (supermarket freezer)-MA home refrigeration-final consumption and other links. This combination of CA and MA technology not only solves the problem of CA storage and outbound Afterwards, the problem of air conditioning was continued,...

Abstract

The present invention discloses a fresh to keeping method for stored cherries, which is characterized in that the method comprises the following steps: A)harvesting, which is performed by combining production and storage and harvesting in batches at proper time points; B) packaging and precooling, which comprises feeding the harvested fruits into packaging boxes with MA (modified atmosphere) fresh to keeping bags as a lining, and precooling in cold storage room at 0+/-1 DEG C, or comprises directly transporting harvested fruits in packaging boxes for storage in CA (controlled atmosphere) storage room; C) transporting or storing, which comprises transporting over a long distance with MA package after tightly sealing bag openings, or comprises storing in MA package after tightly sealing bag openings and transporting in MA package after storage, or comprises putting fruits stored in CA storage room into MA fresh to keeping bags and sealing the bag openings before removal from the storage room; and D) selling, which comprises allowing fruits in MA package to enter the selling stage and consumer households. The method is easy to use, long in storage period and good in fresh to keeping effect, and meets storage and transportation requirements for green foods.

Description

technical field [0001] The invention relates to the technical field of storage, transportation and preservation of fruits and vegetables, in particular to a method for preserving the freshness of stored cherries. Background technique [0002] Sweet cherries are the first high-end fresh fruits to mature among deciduous fruit trees. They are popular with consumers because of their bright colors and rich nutrition. However, the cherries are thin-skinned, soft and juicy. Atrophy, epidermis depression, rupture, mold propagation and spread along the cracks and joints of the fruit stalk, and finally the fruit rots and deteriorates quickly; in addition, cherries, like peaches and other drupes, are prone to pulp browning, Physiological lesions such as decreased taste. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies in the prior art, and provide a method for preserving the freshness of stored cherries, which mainly solves ...
