Abstract:The traditional cold chain has certain limitations in the preservation of fruits and vegetables, such as high energy consumption and difficult to maintain product quality. As a new type of preservation technology, modified atmosphere storage has begun to gradually attract attention. This article will explore the potential of modified atmosphere storage in breaking through the bottleneck of traditional cold chain, introduce its working principle and advantages, and look forward to the future development of this technology.
I. Introduction. The traditional cold chain plays an important role in food preservation, but there are also some bottlenecks and challenges. Problems such as high energy consumption, cold chain disruption, and deterioration in quality limit its further development. In recent years, as a new type of preservation technology, the modified atmosphere fresh-keeping warehouse provides a new idea for solving the bottleneck problem of the traditional cold chain.
Second, the working principle of the modified atmosphere fresh-keeping warehouse.
1.The modified atmosphere preservation warehouse uses the adjustment of gas composition and concentration in the storage environment to delay the physiological metabolism of fruits and vegetables and the growth of microorganisms, so as to prolong the shelf life. It is mainly achieved through the following aspects:
2.Reduce oxygen concentration: moderately reduce the oxygen concentration in the storage environment, slow down the respiration of fruits and vegetables, and inhibit the quality decline and oxidation reaction of fruits and vegetables.
3.Control carbon dioxide concentration: Increase the carbon dioxide concentration in the storage environment, reduce the consumption of organic matter in fruits and vegetables by regulating the rate of respiration to prolong the shelf life.
4.Humidity regulation: Control the humidity in the storage environment to prevent the rapid loss of moisture from fruits and vegetables and maintain their freshness.
3. Advantages of modified atmosphere fresh-keeping warehouse.
1.Extend the shelf life: By reasonably adjusting the gas composition, the modified atmosphere preservation warehouse can significantly extend the shelf life of fruits and vegetables and improve the product quality.
2.Reduce energy consumption: Compared with the traditional cold chain, the modified atmosphere storage can reduce energy consumption to a certain extent and reduce the use of cooling equipment.
3.Reduce quality loss: The modified atmosphere storage warehouse can accurately control the parameters of the storage environment to reduce the quality loss and nutrient loss of fruits and vegetables.
4.Enhance market competitiveness: Modified atmosphere storage can help the fruit and vegetable industry to extend the first cycle, expand the market sales time, and enhance competitiveness.
Conclusion: As a new type of preservation technology, modified atmosphere storage has great potential, which is helpful to solve the bottleneck in the traditional cold chain. By adjusting the gas composition and concentration in the storage environment, the modified atmosphere storage can effectively extend the shelf life of fruits and vegetables, reduce energy consumption, and reduce quality loss. In the future, we can look forward to the further development and application of modified atmosphere storage technology to provide more feasible solutions for fruit and vegetable preservation.
