Problems solved by technology

The time of short-term decompression treatment is generally within 48 hours, and it is used as a pretreatment method; while the conventional decompression storage is to keep fruits and vegetables in a decompression environment from picking to before going on the market, and the storage time is longer. The weight loss rate and flavor are greatly affected, and the storage cost is also high

Embodiment 1

[0029] A kind of fresh-keeping method of mulberry, carries out according to the following steps:

[0030] (1) raw material preparation: mulberries are 9 mature fruits without mechanical damage and pests and diseases;

[0031] (2) Short-term decompression pretreatment: the mulberries in step (1) were divided into PET plastic boxes with a capacity of 0.5 L, and 30 fruits were placed in each box. Place the subpackaged mulberries in a 45±5kPa pressure tank, take them out of the decompression tank after 24 hours, and place them under normal pressure.

[0032] (3) The mulberries in step (2) are stored in a cold storage with a temperature of 1° C. and a relative humidity of 90%, and the storage period is 5 days.

Embodiment 2

[0034] A kind of fresh-keeping method of mulberry, carries out according to the following steps:

[0035] (1) Raw material preparation: mulberries are 8 mature fruits without mechanical damage and pests and diseases;

[0036] (2) Short-term decompression pretreatment: the mulberries in step (1) were divided into PET plastic boxes with a capacity of 0.5 L, and 40 fruits were placed in each box. Place the subpackaged mulberries in a 55±5kPa pressure tank, take them out of the decompression tank after 24 hours, and place them under normal pressure.

[0037] (3) Carry out modified atmosphere packaging of step (2) mulberries, and the packing box is filled with a composition of 10% CO 2 , 5O 2 % and 85%N 2 The mixed gas is then stored in a cold storage with a temperature of 1°C and a relative humidity of 90%, and the storage period is 8 days.

Embodiment 3

[0039] A kind of fresh-keeping method of mulberry, carries out according to the following steps:

[0040] (1) Raw material preparation: mulberries are 8 mature fruits without mechanical damage and pests and diseases;

[0041] (2) Short-term decompression pretreatment: the mulberries in step (1) were divided into PET plastic boxes with a capacity of 1 L, and 60 fruits were placed in each box. Place the divided mulberry in a 65±5kPa pressure tank, take it out of the decompression tank after 12 hours, and place it under normal pressure;

[0042] (3) The mulberries of step (2) are stored in a cold storage with a temperature of 5° C. and a relative humidity of 95%, and the storage period is 3 days.

Abstract

The invention belongs to the technical field of storage preservation of agricultural products, and particularly relates to a preservation method for mulberries. The method is implemented by the following steps: (1) preparing raw materials, wherein the storage mulberries are mature fruits free of mechanical damage and pest and disease damage; (2) performing short-time pressure reduction treatment, to be specific, separately packaging the mulberries in step (1) in PET (polyethylene glycol terephthalate) plastic boxes, placing the separately packaged mulberries in a (45-65)+ / -5kPa pressure tank, taking out the mulberries from the pressure tank after 12 to 24 hours, and placing the mulberries under normal pressure; (3) storing the mulberries in a cold storage or an air-conditioning cold storage until a storage period is ended. According to the method, the problems of short storage period and high rotting rate of a conventional mulberry storage method are solved, the storage period of the mulberries is prolonged from original 1 day to 3 to 8 days, and compared with a chemical substance preservation method, the method has a safety advantage.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and in particular relates to a method for preservation of mulberries. Background technique [0002] Mulberry is also called mulberry, mulberry, etc. It is the fruit of the mulberry tree of the Moraceae plant. It has a delicious taste and rich nutrition. Traditional Chinese medicine has found that mulberry has the effects of nourishing yin and kidney, and pleasing the face. Modern medical research has proved that mulberry contains antioxidant The aging-related active ingredients anthocyanins, polyphenols, and Vc can delay the aging of the body [1] . Moreover, eating mulberries often can significantly improve human immunity, so mulberries are known as "the best health fruit in the 21st century" by the medical community. [2] . However, the maturity period of mulberry is very short, and the moisture content of mature mulberry is above 80%. [3] , the skin ...
