example 1

[0019] Example 1: In sunny weather, harvested 8~9 mature, no pests, no mechanical damage, hardness 6.5Kg / cm 2 Left and right, Fuji apples with a soluble solid content of more than 13%, put the apples in plastic boxes, cartons, foam boxes, and wooden boxes with good air permeability, transport them back as soon as possible, and put them in the refrigerator. For 1-MCP treatment, the treatment temperature is 2-4°C, and the fumigation time is 24 hours. During storage, the storage temperature should be controlled at -1.0~-0.5°C (core temperature), and the humidity should be 90~95%. Take ventilation to control CO 2 The concentration is about 0.9%. Ventilation is carried out when the temperature difference between the inside and outside of the storage is the smallest. It is once a day in the early stage of cooling down, and about 2 times a week after the fruit temperature is stable. The ventilation time is determined according to the size of the storage. After 8 months of storage, ...

example 2

[0020] Example 2: Apples are packaged in fresh-keeping bags after harvesting, and the fresh-keeping bags are perforated. Each hole is more than 20, and the hole diameter is about 2cm. The ventilation holes are distributed at the bottom and around. It is recommended to use grids around and around the bottom of the wooden box Foam spacer, the bag mouth is folded flat and sealed with tape. When apples are treated with 1-MCP, the treatment temperature is 20°C, the fumigation time is 8 hours, and then stored in cold air storage. During storage, control the storage temperature at 0°C (fruit core temperature), humidity at 90-95%, and use ventilation to control CO 2 The concentration is about 0.7%, and after being stored for 8 months, the apples have high hardness, good flavor and good taste. In the storage environment, CO 2 For apples with a concentration of 1.3% (other conditions are the same), after 4-5 months of storage, part of the epidermis will appear brown, and epidermal dam...

example 3

[0021] Example 3: Storage in a controlled atmosphere warehouse. During storage, the temperature is -0.5°C±0.2 (core temperature), and the gas composition is O 2 : 3%~4%, CO 2 : 0.9~1.0%. Other technical requirements are the same as embodiment 1. After 10 months of storage, the quality of apples remained good, and the incidence of tiger skin disease was very low or even non-existent. After leaving the warehouse, the color, taste and flavor will change little within 20 days under the premise of moisturizing.

Abstract

The invention discloses a refrigerating method of Fuji apples based on 1-methylcyclopropene. Fuji apples with suitable ripening degree are fumigated by the 1-methylcyclopropene after harvested, the treatment time is scientifically determined according to the treatment temperature and suitable temperature and humidity and gas components are controlled after the treatment. The main technology is as follows: the gas components in storage duration environment is controlled, wherein the concentration of CO2 is controlled to be less than 1 percent by adopting a ventilating mode during storage in a cold air store; and the concentration of CO2 is 0.9-1.0 percent when the concentration of O2 is 3-4 percent and the concentration of CO2 is 1.0-1.1 percent when the concentration of O2 is 4-5 percent during storage in an air conditioned cold store. After stored by the technology for 10 mouths, the Fuji apples have high rigidity, good flavor and mouthfeel without carbon dioxide damage; and the superficial scald occurrence rate is very low, even the superficial scald can not occur, thereby prolonging the shelf life of the Fuji applies out of the storage.

Description

(1) Technical field [0001] The invention relates to a post-harvest preservation technology for fruits, in particular to a refrigeration method for processing Fuji apples based on 1-methylcyclopropene. (2) Background technology [0002] The total area and total output of apples in my country rank first in the world, and China is the largest country in apple production in the world. After joining the World Trade Organization, apples are one of the few agricultural products in my country with obvious international competitiveness. Fuji apple has a late maturity period, high hardness and good quality. It is the main apple variety for storage and domestic and foreign sales in my country's fresh-keeping enterprises. [0003] Apple is a climactic fruit, and the post-harvest fruit is affected by ethylene, which greatly shortens the storage period. 1-Methylcyclopropene (1-MCP) is a very effective inhibitor of ethylene production and ethylene action. 1-MCP can prevent the combinatio...
