Problems solved by technology

However, in the hot summer season, fruits often suffer from diseases after harvesting in a short period of time, and are very prone to mold, rot and spoilage. It is extremely difficult to protect, store and transport, and the postharvest loss is serious, which greatly reduces the edible quality of stored fruits. Economic value and health security
At the same time, if a large amount of fruit floods into the market in a short period of time, it will often lead to a sharp drop in its price, impacting the local market

Embodiment 1

[0034] The present embodiment provides a fresh-keeping storage method of post-harvest cherries, specifically:

[0035] (1) Harvesting: 8 ripe cherries picked at 6:00 a.m. are placed in plastic or rattan turnover boxes (porous containers), 10 kg per box, to avoid direct sunlight to prevent fruit temperature rise and water loss;

[0036] (2) Pre-cooling: Soak in cold water at a temperature of 2°C for 10 minutes, take it out, and place it in a 1-4°C refrigerator (with a certain dehumidification function) to filter water for 1 hour;

[0037] (3) Packing: select the oxygen permeability rate of 800 (mL / 24h m 2 The packing material of 101kPa) carries out bagging modified atmosphere packaging to cherries, every bag 5 kilograms; Contain the oxygen of concentration 8%, the carbon dioxide of concentration 13% in the mixed gas that described modified atmosphere packaging uses, and surplus is nitrogen;

[0038] (4) refrigerated under the condition of 4 DEG C, under the condition that the ...

Embodiment 2

[0040] The present embodiment provides a fresh-keeping storage method of post-harvest cherries, specifically:

[0041] (1) 7 ripe cherries picked at 10:00 a.m. are placed in plastic or rattan turnover boxes (porous containers), 15 kg per box, to avoid direct sunlight, to prevent fruit temperature rise and water loss;

[0042] (2) Pre-cooling: place it in a 2°C refrigerator (with a certain dehumidification function), and use circulating cold air to pre-cool for 5 hours;

[0043] (3) Packaging: choose oxygen permeability rate 18000 (mL / 24h m 2 The packing material of 101kPa) carries out sealing modified atmosphere packaging to cherries, every case 50 kilograms; The mixed gas that described modified atmosphere packaging uses contains the oxygen of concentration 8%, the carbon dioxide of concentration 13%, and the balance is nitrogen;

[0044] (4) Refrigerate at 1° C., and the storage period is 60 days under the condition that the intact rate of cherries reaches more than 98%.

Embodiment 3

[0046] The present embodiment provides a fresh-keeping storage method of post-harvest cherries, specifically:

[0047] (1) 8 ripe cherries picked at 8:00 a.m. are placed in plastic or rattan turnover boxes (porous containers), 10 kg per box, to avoid direct sunlight to prevent fruit temperature rise and water loss;

[0048] (2) Pre-cooling: soak in cold water at a temperature of 3°C for 12 minutes, take it out, and place it in a 2°C refrigerator (with a certain dehumidification function) to filter water for 1 hour;

[0049] (3) Packing: select the oxygen permeability rate of 800 (mL / 24h m 2 The packing material of 101kPa) carries out bagging modified atmosphere packaging to cherries, every bag 5kg; Contain the oxygen of concentration 8%, the carbon dioxide of concentration 13% in the mixed gas that described modified atmosphere packaging uses, the balance is nitrogen;

[0050] (4) Refrigerate at 7°C, and the storage period is 10 days under the condition that the intact rate o...

Abstract

The invention relates to a fresh-keeping storage method for harvested fruits. The method comprises the following steps: (1) conducting harvesting: harvesting fruits with a certain maturity before 11 am, avoiding mechanical damage when harvesting, temporarily placing the fruits in farming field after the harvesting, and avoiding direct sunlight drying on transportation way; (2) conducting pre-cooling: starting pre-cooling the fruits in 5 hours after the harvesting; (3) conducting packaging: choosing packaging materials with suitable oxygen permeability, and carrying out modified atmosphere packaging with mixed gas containing oxygen, carbon dioxide and nitrogen; and (4) conducting cold storage. The fresh-keeping storage technology for the harvested fruits and provided by the invention can keep the edible quality of the fruits, reduce rot and diseases and prolong shelf life by inhibiting the respiration of the fruits after the harvesting. The method not only solves the problem that fruitscannot be stored for a long time, but also solves transportation problems, provides technical solution schemes for realizing off-peak sales and long-distance transportation, and has good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and in particular relates to a technology for keeping fruits fresh by inhibiting respiration after harvesting. Background technique [0002] Summer is the season when many fruits are ripe and harvested. However, in the hot summer season, fruits often suffer from diseases after harvesting in a short period of time, and are very prone to mold, rot and spoilage. It is extremely difficult to protect, store and transport, and the postharvest loss is serious, which greatly reduces the edible quality of stored fruits. Economic value and health security. At the same time, if a large amount of fruit floods into the market in a short period of time, its price will often drop sharply, impacting the local market. [0003] In recent years, with the improvement of people's requirements for food freshness and food safety and the diversity of sales methods, especially the rapid d...
