Research subjects: Fruit of 10 appricot cultivars zonated in Armenia. Research objectives: To investigate the effect of low-temperature freezing on the technological quality indices of appricots. Methods: Conventional methods applied in the agricultural products storage sector. Theoretical and practical results: Criteria were established pertaining to the selection of appricot cultivars suitable for lowtemperature freezing and long-term storage followed by processing into juices, compotes and jams. The criteria are currently employed in Ukraine in view to scientifically predict and select cultivars of the recognized and promising assortment of the southern horticultural zone. Technological instructions for the production of the above products were developed. Novelty of introduced: Criteria were determined allowing to predict suitability of appricot cultivars to low-temperature freezing and long-term storage: low dejuicing when thawed, low levels of polyphenolic substances (catechines, chlorogenic acid) , high levels of sugars. Groups B and C vitamins, good total indice of gustatory qualities. Implementation degree: The Technological Instructions developed are currently employed at refrigeration enterprises and fruit-and vegetable-processing wineries of Ukraine. Effectiveness: The economical effect can be 500 hrn/t from storage, 4840 hrn from the sale of 1000 conditional cans of compote and 1940 hrn from 1000 conditional cans of jam Sphere, sector of implementation: Fruit-processing sector of agriculture.
