Embodiment 1

[0016] The implementation is carried out with fresh green beans: stop watering one week before harvesting, transport them back to the laboratory after harvesting, dissipate the heat in the field, and sort them at the same time, select pods of uniform size, and remove mechanical damage, defects, and pods caused by diseases and insect pests. When the temperature drops to 15°C, two ways are used: (1) Put it into a 40μm thick PE fresh-keeping bag, 5kg per bag, put 0.5μL / L equivalent of 1-MCP slow-release agent in the bag, Airtight fumigation at 15-20°C for 3 hours, pre-cooling at 10±1°C and relative humidity ≥85% for 24 hours, then bagged and stored in a cold storage at 9±1°C and relative humidity ≥85%; (2) Not used 1-MCP was fumigated and stored in modified atmosphere packaging at 25±1 and 3±1°C and 85% relative humidity as controls. After the pods treated with (1) were stored for 60 days, the fresh pods were complete in shape, bright in color, the Vc retention rate was 86%, and ...

Embodiment 2

[0018] Implementation with fresh cowpea: stop watering one week before harvesting, transport back to the laboratory after harvesting, dissipate the heat in the field, and sort the pods at the same time, select pods of uniform size, remove mechanical damage, defective pods, and pods with diseases and insect pests, and the temperature drops to At 15°C, two methods are used for treatment: (1) Put it into a 20μm thick PE fresh-keeping bag, 5kg per bag, put 2.0μL / L equivalent 1-MCP slow-release agent in the bag, and put it in 15~ Airtight fumigation at 20°C for 3 hours, pre-cooling at 10±1°C and relative humidity ≥85% for 24 hours, then bagged and stored in a cold storage at 9±1°C and relative humidity ≥85%; (2) Do not use 1- MCP fumigation and modified atmosphere packaging were directly stored at 9±1°C and 85% relative humidity as controls. After the pods treated with (1) were stored for 50 days, the Vc retention rate of fresh pods was 81.6%, and the rot rate was 9.1%; while the p...

Embodiment 3

[0020] The implementation is carried out with fresh Thai gluten-free beans: stop watering one week before harvesting, transport them back to the laboratory after harvesting, dissipate the heat in the field, and sort them at the same time, select pods of uniform size, and remove mechanical damage, defective pods, and pests When the temperature drops to 15°C, two ways are used for treatment: (1) Put it into a 40μm thick PE fresh-keeping bag, each bag contains 5kg, and put 0.5μL / L equivalent of 1-MCP slow-release agent in the bag, Airtight fumigation at 15-20°C for 3 hours, pre-cooling at 10±1°C and relative humidity ≥85% for 24 hours, then bagged and stored in a cold storage at 9±1°C and relative humidity ≥85%; (2) adopt The PE modified atmosphere packaging was stored at 9±1°C and the relative humidity was 85% as the control. After the pods treated with (1) were stored for 60 days, the fresh pods were complete in shape, bright in color, the Vc retention rate was 82.8%, and the r...

Abstract

The invention discloses a fresh-keeping method for prolonging the shelf life of fresh-eating kidney beans, which belongs to the field of agricultural food science and technology. The purpose of freshness preservation is achieved by suppressing the disease by adopting the method of spontaneous modified atmosphere packaging, postharvest physiological regulator and low temperature storage. After harvesting fresh beans, pre-cool them to reduce the heat in the field, and sort them to remove mechanical damage, defective pods, and pests. After sorting, put them into PE fresh-keeping bags with a thickness of 20-40 μm, at a rate of 0.5-2.0 μL / L 1 - Add the equivalent concentration of MCP into a fresh-keeping bag, tie the bag and fumigate at 15-20°C for 2-4 hours, then open the bag, pre-cool in a fresh-keeping store at 10±1°C and relative humidity ≥85% for 24-48 hours, and store it at 9±1°C 1 ℃, relative humidity ≥ 85% fresh storage. An efficient, convenient, and simple-to-operate fresh-keeping method for fresh kidney beans.

Description

technical field [0001] This patent relates to the field of agricultural food science and technology, in particular to a fresh-keeping method for prolonging the shelf life of fresh kidney beans. technical background [0002] High-efficiency storage and fresh-keeping technology of fruits and vegetables is the key to avoiding fruit and vegetable rot in peak season, off-season and rot during storage and transportation, expanding the sales radius, reducing economic losses, and realizing "high yield and harvest". In recent years, with the improvement of living standards, people have higher and higher requirements for the quality of food. Therefore, cheap, efficient and convenient fruit and vegetable preservation technology has great market prospects. [0003] Spontaneous modified atmosphere packaging technology has been widely recognized for its unique ability to adjust the gas concentration and relative humidity in the storage environment. It is currently one of the most widely ...
