METHODS OF PROCESSING SUBTROPICAL AND SOUTHERN FRUIT CROPS (LITERATURE REVIEW)

The paper describes the main ways of processing subtropical crops. The aim of this work was to identify the efficiency of processing for subtropical and southern fruit crops based on the research of Russian and foreign scientists, which can expand the range of final products and increase profits in the processing industry sector. Currently, subtropical crops are becoming increasingly popular due to their unique flavor and nutritional qualities. However, the presence of a short ripening season and rapid deterioration of quality after harvesting poses a challenge to the preservation, transportation and use of these crops. This paper considers several methods of processing fruits for their long-term storage and utilization. Preservation methods such as aseptic canning, production of juices, snacks, squeezes and varieties of freezing at different temperatures are analyzed. The terms blanching and defrosting, convection and solar panel drying, and freeze drying are defined. The results of the study allow analyzing how each of the processing methods contributes to the preservation of nutritional value and increases the crops’ shelf life. In addition, recommendations on the optimal use of these methods in various conditions and for different types of subtropical and southern fruit crops that can be used by farmers, producers and consumers are considered, which contributes to the development of the industry and increases the availability of these products on the market.
