Introduction: Grapes are perishable fruits, and their freshness and quality preservation have always been the focus of attention of consumers and merchants. The advanced preservation technology of controlled atmosphere cold storage can provide an ideal storage environment for grapes, and realize the dual guarantee of preservation and quality improvement. This article will be the principle and advantages of grape controlled atmosphere cold storage.
1. The principle of grape controlled atmosphere cold storage Grape controlled atmosphere cold storage is a kind of cold storage specially used for grape storage, which provides the best storage environment for grapes by adjusting the temperature, humidity and gas composition in the warehouse. Its key features include:
1.Low temperatures: Controlled atmosphere cold storage keeps the temperature within the optimal storage temperature range for grapes. Low temperatures can slow down the metabolism of grapes, delay fruit rot and deterioration of quality.
2.Humidity control: Grapes require high humidity during storage. The humidity control system keeps the humidity in the controlled atmosphere storage room within the optimal storage range of grapes. Humidity control reduces water loss from the grapes and preserves the fullness and taste of the fruit.
3.Gas composition regulation: Controlled atmosphere cold storage creates a gaseous environment conducive to grape storage by controlling the oxygen and carbon dioxide concentrations in the storage. Typically, controlled atmosphere cold storage keeps oxygen concentrations low and carbon dioxide concentrations high to inhibit respiration and microbial activity in the grapes.
2. Advantages of grape controlled atmosphere cold storageThe application of grape controlled atmosphere cold storage provides a double guarantee for grape preservation and quality improvement, and the specific advantages are as follows:
1.Good preservation effect: The regulation of low temperature, humidity and gas composition can effectively delay the aging process of grapes and maintain the freshness and nutrients of the fruit. Grape controlled atmosphere cold storage has a better preservation effect than traditional storage methods.
2.Quality improvement: Controlled atmosphere cold storage can reduce the occurrence of diseases during the storage of grapes, reducing the risk of rot and spoilage. At the same time, by controlling the gas composition, the color, texture and flavor of the grapes can be maintained, and the market competitiveness of the product can be enhanced.
3.Extend the storage period: The storage environment of the controlled atmosphere cold storage of grapes can greatly extend the storage period of grapes, so that the grapes can maintain good quality for a long time and reduce the waste of resources.
Conclusion: Grape controlled atmosphere cold storage provides an ideal storage environment for grapes through the adjustment of low temperature, humidity and composition, and realizes the dual guarantee of preservation and quality improvement. Its application can not only extend the storage life of grapes, but also maintain the freshness and nutrient content of the fruit, and improve the market competitiveness of the product. With the continuous development of controlled atmosphere cold storage technology, the storage and circulation of grapes will become more efficient and safer. Cold storage construction
