Embodiment 1

[0011] Eight mature peaches were selected for picking, and stored under controlled atmosphere after pre-cooling at a storage temperature of 0-2°C. Artificially increase ethylene gas in the controlled atmosphere storage, the concentration range of ethylene is 5-50ul / l, keep this concentration until the end of storage. Since the controlled atmosphere storage is not absolutely airtight, the ethylene concentration in the storage will gradually decrease. When the ethylene concentration is lower than 5ul / l, it needs to be replenished.

[0012] Changes of Main Volatile Aromatic Substances in Peach Fruit

[0013] Figure 1, Figure 2 and Figure 3 are the GC spectra of peach fruits stored for 10 days, 30 days and 50 days respectively. It is found that peach fruits treated with high-concentration exogenous ethylene wake-up technology maintain good flavor during each storage stage. The study also showed that high-concentration exogenous ethylene awakening technology to treat peach fruit b...

Embodiment 2

[0016] Eight mature peaches were selected for picking, and stored under controlled atmosphere after pre-cooling at a storage temperature of 0-2°C. Spray the ethephon solution on the surface of the fruit so that the concentration range of conversion to ethylene is 5-50ul / l, and keep this concentration until the end of storage. After storage for 60 days, the browning rate of the fruit was 85.8% lower than that of the control, indicating that the coloring degree increased by 78.6%.

Embodiment 3

[0018] Eight ripe peach fruits are picked and refrigerated after pre-cooling at a storage temperature of 0-2°C. Spray the ethephon solution on the surface of the fruit so that the concentration range of conversion to ethylene is 5-50ul / l, and keep this concentration until the end of storage. After storage for 60 days, the browning rate of the fruit was 80.5% lower than that of the control, indicating that the coloring degree increased by 75.3%.

Abstract

A storage method for peach features that in the storage period of peach, the ethylene with 5-50 micron 1 / 1 of concentration is applied for improving taste of peach and elongating storage period.

Description

technical field [0001] The invention relates to a method for improving the storage and preservation effect of peaches, which belongs to the field of post-harvest agricultural products. The method of the invention is suitable for alleviating chilling damage and promoting the formation of peach flavor substances during low-temperature refrigeration or controlled-atmosphere storage of peaches. Background technique [0002] Peach fruit is juicy and delicious, with attractive aroma, bright color and rich nutrition. Peach is a climacteric fruit, and most varieties are harvested in high temperature season, so they are easy to soften and rot after harvesting. Low temperature storage can reduce postharvest respiratory intensity and endogenous ethylene production of peach fruit, effectively inhibit softening and spoilage, and prolong the storage period. However, due to the strong sensitivity of peach fruit to low temperature, chilling injury is easy to occur during low temperature s...
