Commercial atmosphere storage has been preserved in foreign countries for more than 60 years. Most of the long-term storage of fruits in developed countries uses modified atmosphere storage. China's air-conditioning storage began in the 1970s. In the past 30 years, through the introduction, digestion, and absorption of advanced foreign technology and equipment, coupled with constant research and exploration by our country’s scientific researchers, the development of air-conditioning storage technology has grown rapidly. Already have the ability to design and build a variety of air-conditioned storage and air-conditioning equipment. 1. The principle of controlled atmosphere storage Normal air contains oxygen 21%, carbon dioxide 0.03%, and the rest is nitrogen and some trace gases. After harvesting, fresh fruit is still a living living body. During the storage process, normal metabolic activities dominated by respiration are still carried out, mainly because the fruit consumes oxygen while releasing a certain amount of carbon dioxide and heat. In the composition of the ambient gas, carbon dioxide and ethylene released from the fruit have a significant effect on the respiration of the fruit. Reducing the oxygen concentration in the storage environment and appropriately increasing the carbon dioxide concentration can inhibit the respiration of the fruit, thereby delaying the ripening and senescence of the fruit and prolonging the storage period of the fruit. Lower temperature and low oxygen, high carbon dioxide can inhibit the synthesis of ethylene in fruits and weaken the role of ethylene in the promotion of fruit ripening and aging, thereby reducing or avoiding certain physiological diseases. In addition, a certain concentration of low oxygen and high carbon dioxide in the environment has the effect of inhibiting the growth and expansion of fungal diseases. 2. Advantages of controlled atmosphere storage (CA) (1) Long storage time Modified atmosphere storage combines low-temperature (refrigerated) technology with the adjustment of the composition of the atmosphere in the storage environment, resulting in a longer period of fruit storage. With the use of air-conditioned storage, Apple can provide annual supply; Ya pear, long pear, fragrant pears, etc. can be stored for at least 8 to 9 months by using controlled atmosphere storage; the storage of kiwifruit in the modified atmosphere store is 2 to 3 months longer than the cold storage period. the above. (2) Fresh-keeping effect Most of the late-maturing apple and pear, long pear, fragrant pear and other fruits are still bright in color after long-term storage, and the stem is green, pure in flavor, and full in appearance, which is almost the same as when harvested. Taking apples as an example, the indexes such as meat hardness and titratable acidity after air conditioning storage are significantly higher than those of frozen fruits during the same period. (3) Low storage loss Air-conditioned storage strictly controls the internal temperature, humidity, oxygen and carbon dioxide gas components, effectively inhibits the respiration, transpiration, and microbial damage of fruits. It is caused by water loss, rot, etc. during storage. The loss is greatly reduced. According to the observation of Kiwifruit by Henan Institute of Biology, under the same storage conditions, the loss of ordinary cold storage is as high as 15% to 20%, while the total loss of controlled atmosphere storage is less than 4%. In Hebei, a certain air-conditioning storage pear pear was stored for 10 months, and the rate of water loss was almost zero. (4) Long shelf-life After long-term storage of fruits with modified atmosphere, due to long-term low oxygen and high carbon dioxide, after a gas-free state is released, there is still a long time “hysteresis effectâ€. According to Shaanxi's experiments on apples, it is generally believed that under the premise of maintaining the same quality, the shelf life of controlled atmosphere storage is 2 to 3 times that of cold storage. (5) "Green" storage During the process of controlled atmosphere storage of fruit, due to the interaction of low temperature, low oxygen and relatively high carbon dioxide, the occurrence of invasive diseases can be basically suppressed, and basically no chemical drugs are used for preservation during storage. .
