Kiwi is a fruit rich in vitamin C, vitamin E, and fiber, and is loved by people. However, due to its susceptibility to oxidation and decay, kiwifruit is relatively difficult to preserve. In order to prolong the shelf life of kiwifruit and maintain its delicious taste, cold storage technology is widely used in the preservation process of kiwifruit. The following are the key applications of cold storage technology in kiwifruit preservation.
1. Low temperature storage.
Kiwifruit cold storage uses low-temperature storage technology to store kiwifruit at a lower temperature. Low temperature can effectively delay the oxidation reaction and respiration of kiwifruit, inhibit the growth and metabolic activities of microorganisms, and thus prolong the shelf life of kiwifruit.
2. Humidity control.
In the process of keeping kiwifruit fresh, humidity control is also very important. Proper humidity reduces the loss of moisture from the surface of kiwifruit, prevents dehydration and drying of the fruit, and reduces the growth of pathogenic bacteria and molds.
3. Gas regulation.
Gas conditioning in kiwifruit cold storage is key to maintaining kiwifruit freshness and taste. The ventilation system in the cold room can provide fresh air and control the oxygen concentration in the kiwifruit through the discharge of CO2. Proper air circulation and gas regulation can delay the respiration of the fruit and prevent the fruit from suffocating and heat bursting.
Fourth, fresh-keeping equipment.
Fresh-keeping equipment in kiwifruit cold storage is also a key application. The cold storage is equipped with refrigeration equipment, humidity control equipment and gas conditioning equipment, through which suitable temperature and humidity conditions are maintained.
5. Quality inspection.
The kiwifruit cold storage preservation process requires regular quality inspections. It includes the detection of fruit hardness, acidity, sugar content and other indicators, as well as the inspection of appearance and the evaluation of the degree of decay. Through quality inspection, the deterioration of kiwifruit can be found in time and corresponding treatment measures can be taken.
To sum up, cold storage technology plays an important role in kiwifruit preservation. Critical applications such as cryogenic storage, humidity control, gas conditioning, freshness preservation equipment and quality testing extend the shelf life of kiwifruit and preserve its freshness and taste. Through the application of scientific cold storage technology, we can better enjoy the delicious taste of kiwifruit. Cold storage construction
