Scientific significance of using protective devices in pear storage in refrigerated warehouses (in the case of Uzbekistan)

Abstract

In this article, a scientific study on the long-term storage of Santa Maria pears in refrigerated warehouses through using modern protective equipment, special bags and ethylene-absorbing absorbers, was conducted. Accordingly, the main factor influencing the long shelf life of pears was the natural loss during the storage. It was considered that calculation and analysis of effects inducing the natural loss were pivotal to improve the preservation of the fruit, maintain freshness and all useful elements of the fruit, and prolong the storage period. Ethylene absorber and Modified Atmosphere Packaging (MAP) packages were used in the initial research step, and collected pears were placed in the refrigerator at a temperature of 0-2°C in 8 different Options. Results showed that the higher natural loss in the fruit stored without employing any means (in option 1) was 5.45% equal to 193.9 gram, whereas the best result was in Option 7 used the MAP special plastic bag and two pieces of absorbers, and compared to the initial weight, 4099 grams, the natural loss in the fruit was 1.20% equal to 47.7 gram.
