Problems solved by technology

[0004] The object of the present invention is to provide a kind of simple and easy to implement, which can obviously inhibit the wood fibrillation of Zizania, in view of the short storage period of the existing Zizania, which is only 2-3 days, and the preservation method has the defects of insignificant storage effect and potential safety hazards. A storage and fresh-keeping method for wild rice stems that reduces quality decline, prolongs the storage and fresh-keeping period to 60-65 days, and has a commodity rate of more than 90%.

Embodiment 1

[0043] A kind of storage and fresh-keeping method of wild rice stem, carries out according to the following steps:

[0044] (1) Raw material preparation: Harvest the Zizania at the right time for harvesting in time, transport it to the laboratory within 6 hours, select the Zizania of uniform size, maturity, and no damage, diseases and insect pests, and set aside.

[0045] (2) Pre-cooling: place the raw material of Zizania in step (1) in a pre-cooling room at 0°C for pre-cooling, and the temperature of Zizania will reach 3°C after 36 hours of pre-cooling.

[0046] (3) Decompression storage: store the wild rice stem in step (2) in a decompression freezer with a temperature of 1°C, a storage pressure of 70KPa, and a relative humidity of 95%. When the CO in the decompression freezer 2 When the concentration reaches 15%, start to exchange air with the outside of the storehouse, and adjust the CO2 in the storehouse. 2 The concentration was kept below 15% until the end of the storag...

Embodiment 2

[0048] A kind of storage and fresh-keeping method of wild rice stem, carries out according to the following steps:

[0049] (1) raw material preparation: with embodiment 1,

[0050] (2) Pre-cooling: Place the Zizania zizania raw material in step (1) in a pre-cooling room at 2°C for pre-cooling, and the temperature of Zizania zizania in pre-cooling reaches 8°C for 24 hours.

[0051] (3) Decompression storage: store the wild rice stem in step (2) in a decompression freezer with a temperature of 3°C, a storage pressure of 75KPa, and a relative humidity of 90%. When the CO in the decompression freezer 2 When the concentration reaches 15%, start to exchange air with the outside of the storehouse, and adjust the CO2 in the storehouse. 2 The concentration was kept below 15% until the end of the storage period of 60 days.

Embodiment 3

[0053] A kind of storage and fresh-keeping method of wild rice stem, carries out according to the following steps:

[0054] (1) raw material preparation: with embodiment 1,

[0055] (2) Put the Zizania raw material in step (1) in a pre-cooling room at 2°C for pre-cooling, and pre-cool for 36 hours and the temperature of Zizania will reach 3°C.

[0056] (3) Decompression storage: store the wild rice stem in step (2) in a decompression freezer with a temperature of 3°C, a storage pressure of 80KPa, and a relative humidity of 85%. When the CO in the decompression freezer 2 When the concentration reaches 15%, start to exchange air with the outside of the storehouse, and adjust the CO2 in the storehouse. 2 The concentration was kept below 15% until the end of the storage period of 60 days.

Abstract

The invention relates to the field of fruit and vegetable preservation, in particular to a storage and preservation method for wild rice shoots. The method includes the following steps: fresh wild rice shoots are precooled, and are then stored in a hypobaric refrigerator with the temperature of 1 DEG C to 3 DEG C, the storage pressure of 70KPa to 80KPa and the relative humidity of 85 to 95 percent. The method is easy to operate, and can evidently delay the lignifications process of wild rice shoots, and the storage period can reach 60 to 65 days.

Description

technical field [0001] The invention relates to the field of fresh-keeping of fruits and vegetables, in particular to a storage and fresh-keeping method of asparagus. Background technique [0002] Zizania is a characteristic aquatic vegetable in my country. It is not only delicious and nutritious, but also has high medical and health value, especially rich in dietary fiber. It has a significant preventive effect on obesity and hyperlipidemia, and is regarded as a good vegetable. . Zizania zizania meat is tender and has high water content. It is not resistant to storage and transportation after harvesting. The content of lignin and cellulose will increase within 2 to 3 days at room temperature, and then turn red, soften, and bran the tissue, and "wood fibrillation" appears. The quality of wild rice meat has declined, affecting the taste. The main storage methods of Zizania at present are: ①Low temperature storage: Although the storage period of Zizania can be extended to a c...
