Embodiment

[0009] Embodiment: test fruit carries out room temperature storage. Put the fruits into fresh-keeping bags and place them indoors on the first floor of the experimental building. The unbagged fruits were used as the control, the bagged fruits were treated as treatment 1, and the bagged fruits treated with 1-MCP were treated as treatment 2. Treatment 2 Put the fruit in a 15L plastic bucket, weigh 0.05g of 1-MCP and place it in a 50ml beaker, put the beaker into the bucket, add 5ml of distilled water, stir for 2-3s, seal the bucket immediately, the concentration of 1-MCP in the bucket is about 0.5mL / L, sealed at room temperature (25°C) for 24 hours. During the storage period, samples were taken every 3 days for relevant index determination. During the measurement, 20 fruits were taken from each treatment each time, and repeated 3 times.

[0010] The experimental data obtained are as follows:

[0011] (1) Under normal temperature storage conditions for bagged Gala apples, the ...

Abstract

The invention discloses a method for improving the physiological and biochemical characteristics of a bagged gala apple in a storage period. The method is characterized in that the bagged gala apple is subjected to 1-methylcyclopropene (1-MCP) treatment after being picked and put into a freshness protection package to be stored at normal temperature. A 1-MCP treatment method comprises the steps of putting the bagged gala apple in a closed container, filling 1-MCP with the concentration of 0.5mL / L into the closed container, and sealing and maintaining for 20-30h at the temperature of 20-25 DEG C. The method has the advantages that the fruit is subjected to 1-MCP treatment after being picked, 1-MCP is served as a gas to be filled into the fruit, and the respiration intensity, relative membrane permeability, malondialdehydebis content and weight loss ratio of the fruit are inhibited through inhibiting ethylene, so that firmness and quality of the fruit are effectively maintained; and a freshness protection package storage technology can be effectively applied to keep the bagged gala apple fresh at normal temperature.

Description

technical field [0001] The invention relates to a method for storing and preserving fruits at room temperature, in particular to a method for improving the physiological and biochemical characteristics of bagged Gala apples during storage. Background technique [0002] In the late 1980s, in order to improve apple quality and reduce pesticide residues, my country introduced bagging cultivation technology from Japan. In recent years, it has been widely used in various fruit producing areas. Practice has proved that bagged apples have the advantages of smooth fruit surface, bright color, less disease and insect pests, and low pesticide residues, which can increase the commodity value of fruits and increase economic benefits. an important technology. However, research and production practice have found that while bagging improves the appearance quality of apples, it has a negative impact on its internal quality, such as the content of sugar, acid, and VC in the bagged fruit dec...
