Today, with the help of technology, storage activities are carried out in modern facilities where the products can be stored for a long time, by controlling heat and humidity composition of the storage room, and minimizing the deterioration and decay of the product. Bursa and Yalova are among our important provinces due to their proximity to production and consumption areas for the preservation of horticultural crops. In these regions, cold storage facilities have recently become a rapidly developing and expanding sector. Our study, has tried to determine the losses in the types of fruits and vegetables stored according to the capacities of the enterprises in both provinces and the problems experienced today. In Bursa and Yalova, the current situation of the enterprises engaged in the storage of fresh fruits and vegetables and a current capacity of at least 2000 tons/year and cold storages with a usable capacity of at least 3000 tons/year have been studied. Businesses are classified according to their storage types and technologies (Normal Atmosphere, Controlled Atmosphere, Dynamically Controlled Atmosphere, Modified Atmosphere, Freshcut and Frozen); A total of 37 cold storage facilities, 8 in Yalova and 29 in Bursa, were examined. While an average of 7.31% loss occurs in fruit types stored under normal atmosphere conditions; It has been determined that there is a total of 9.32% of unavailable and lost products in all fruit and vegetable types under frozen storage.
