Recently, tropical fruits are in great demands in Japan. About 100 tons of mango fruits were produced in Okinawa Islands in 1988. This study aims at technical establishment of CA storage and long-distance transportation technology for tropical fruits. 680 kg of mangoes (Irwin) were transported by 2-ton refrigerator van under 12゜C on a car ferryboat, from Okinawa Islands to Tokyo Port, from Tokyo To tsukuba university by land, It took 4 days. After that, the van was remade into CA storage chamber. The gas composition 02/N2/CO2 in the chamber was adjusted to 5/90/5%. Ethylene that comes from the fruits was absorbed and decomposed with activated charcoal/vanadium oxide catalyst.The method of adjustent of gas composition for the storage used the gas-purge procedure with high pressure cylinders of N2 and 02. The following major results were obtained; 1. In the quality evaluation of Mango fruits, the hardness of fruit surface related with sugar and acidity ratio significantly. 2. A month-long CA storage was possible. The following technological problems of transportation and storage were examined; 1) Gas composition of 02/N2/CO2 in the fruit tissue was 20/78/2%. 2) Ethylene gas generation rate was exponentially proportioned to the increase of Mango fruits ripening grade. 3) By chilling injury test, minimum temperature in the CA storage could be lowered to 8 0.5.

最近，日本对热带水果的需求量很大。1988年冲绳群岛生产了约100吨芒果。本研究旨在建立热带水果气调贮藏及长途运输技术体系。680公斤芒果（欧文）由2吨冷藏货车在12摄氏度以下的汽车渡船上运输，从冲绳到东京港，从东京到筑波大学，用了4天时间。之后，这辆货车被改造成了CA储藏室。将室中的气体组成O2/N2/CO2调节至5/90/5%。采用活性炭/钒氧化物催化剂吸收分解果实中的乙烯，采用高压氮气和氧气钢瓶吹扫的方法调整贮藏气体成分。主要研究结果如下：1.在芒果果实品质评价中，果面硬度与糖酸比显著相关。2.一个月的CA存储是可能的。研究结果表明：（1）果实组织气体组成为O2/N2/CO2 = 20/78/2%; 2)乙烯气体产生速率与芒果果实成熟度的增加呈指数关系。3)冷害试验表明，气调贮藏的最低温度可达8 0.5 ℃.
