EVALUATION OF THE APPLE-TREE FRUITS OF EARLY RIPENING PERIODS FOR SUITABILITY TO STORAGE AND PROCESSING

Abstract

In 2019–2020 in the RUE “Institute of Fruit-growing” research was carried out to determine the apple-tree fruits of early
 ripening period suitability to storage and processing.
 The objects of research were the fruits of seven apple-tree species of early ripening period (Aksamit, Kovalenkovskoe,
 Mechta, Palanez, Papirovka, Ranak, Slava pobeditelyam), grown in the department of selection of fruit crops of the
 RUE “Institute of Fruit-growing”.
 The storage period for the apple-tree fruits of early ripening period ranged from 44 to 110 days, depending on the species
 and storage option.
 The application of the “Fitomagˮ preparation before storage allowed to achieve the best indicators in terms of storage
 duration – from 73 to 110 days depending on the species.
 The change of the gas composition in a closed package allows to reduce the natural weight loss on average for species
 by 2.8 % and to increase the output of healthy fruits in all the species.
 The suitability of the species Ranak, Mechta and Papirovka for the frozen applesauce production has been established.
