Embodiment 1

[0022] The invention provides a cold storage and preservation method of green peppers, the specific operation steps are as follows:

[0023] S1. Harvesting: Harvest in the morning and evening when there is no dew and no rainy weather and the temperature is cool. When harvesting, use rust-free scissors to cut off the green peppers together with the handle to prevent the green peppers from accumulating water and causing the green peppers to rot during storage. It can better store fresh green peppers;

[0024] S2, the green pepper that step S1 is picked is packed in the packing bag of bag hole;

[0025] S3, pre-cooling: place the bagged green peppers at a temperature of 15-20°C for 2.5-4 hours for pre-cooling before the green peppers are stored, and ensure that the ambient humidity at the green peppers pre-cooling area is 80%-90% Avoid the dehydration and wrinkling of green peppers caused by low air humidity, and ensure the integrity of the appearance of green peppers. The main ...

Embodiment 2

[0029] The invention provides a cold storage and preservation method of green peppers, the specific operation steps are as follows:

[0030] S1. Harvesting: Harvest in the morning and evening when there is no dew and no rainy weather and the temperature is cool. When harvesting, use rust-free scissors to cut off the green peppers together with the handle to prevent the green peppers from accumulating water and causing the green peppers to rot during storage. It can better store fresh green peppers;

[0031] S2. Screening: After the green peppers are harvested, they are graded according to dark green, fully expanded, hard, and bright green peppers, and then the green pepper leaves, diseased and pest green peppers, injured green peppers and young peppers are removed, and the selected green peppers are selected according to an appropriate proportion. Put it in a packaging bag with a hole in the bag, and handle it with care during the period to avoid damage to the appearance of th...

Abstract

The invention discloses a cold storage and fresh keeping method of green peppers, and particularly relates to the field of vegetable storage. The cold storage and fresh keeping method of green pepperscomprises the steps of harvesting, screening, pre-cooling, warehousing and storing, and regular inspecting. According to the method, screening and precooling steps are carried out, packaging materials need to be disinfected and sterilized before harvested green peppers are bagged, 50% procymidone is sprayed to the green peppers for chemical treatment, necessary chemical treatment needs to be carried out on the stored green peppers, gray mold can be prevented and treated, and the storage effect is guaranteed; the green peppers are packaged by woven bags or perforated PP material bags, so thatair interaction between the green peppers and outside air in the storage process can be guaranteed, the storage microenvironment is improved, bacteria breeding due to air non-circulation is prevented,the breathing intensity of the green peppers can be reduced through pre-cooling, the dew formation phenomenon in storage is reduced, and the purposes of preventing the green peppers from aging and prolonging the storage period of the green peppers are achieved; and meanwhile, the freshness of the green peppers can be maintained through precooling, and therefore the cold storage effect on the green peppers is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vegetable storage, and more specifically, the invention relates to a method for cold storage and preservation of green peppers. Background technique [0002] Green pepper belongs to the plant kingdom, dicotyledonous plant class, chrysanthemum subclass, solanaceae. and red peppers are collectively referred to as peppers.
