Abstract

Every year, hundreds of thousands of tons of fruits and vegetables are supplied to the territory of the Russian Federation by exporting producers from different countries. During transportation and storage, the supplied fruits and vegetables undergo various physical and biochemical changes, leading to weight loss and changes in quality indicators. Loss of moisture during transportation is one of the main causes of damage to fruits and vegetables. The relevance of the research topic is determined by the need to minimize the loss of mass and moisture of exotic fruits during transportation and storage in warehouse conditions.Objective: to establish the rates of loss of 10 samples of exotic fruits. The samples included Thai pineapple, Thai watermelon, guava, cantaloupe melon, carambola, Thai mango, papaya of Holland variety, green papaya, passionflower (passion fruit, pitaya). The fruits were transported by air from Thailand (Bangkok) to Krasnoyarsk. The flight duration was 8 hours, flight altitude – 10,000 m. The storage conditions were as follows: temperature – 5–8°C, humidity – 47%, storage time – 10 days in winter period. The paper presents the results obtained for the dynamics of mass and humidity during transportation by air of samples of exotic fruits and during storage in warehouse conditions. It was established that the loss of mass and moisture of exotic fruits in the process of transportation and storage occurred in all samples. The highest percentage of weight loss was observed in Thai mango and amounted to 2.93%. The greatest loss of moisture during storage in warehouses was observed in Thai watermelon (3.5%), the smallest – in Thai pineapple (0.5%). The largest weight loss was set for guava (4.6%), the smallest – for Thai watermelon (0.5%).
