Abstract:

The data of the technological assessment of the suitability of five new winter apple cultivars of VNIISPK breeding (‘Aleksandr Boyko’, ‘Blagodat’, ‘Vavilovskoye, Ivanovskoye’, ‘Patriot’ and ‘Prazdnichnoye’) for the production of raw materials for juice industry are presented. The main technological indicators characterizing the suitability of the cultivar for juice production were studied: the firmness of the pulp, the yield of juice, the content of soluble solids, sugars, titratable acids and catechins in comparison with the standard cultivar ‘Antonovka’. It was found that all of them were distinguished by a higher content of soluble solids and sugars in the juice than in the standard cultivar, and a lower content of titrated acids, as well as higher tasting ratings. ‘Aleksandr Boyko’ surpassed all studied cultivars in terms of such indicators as juice yield, the content of soluble solids, sugars and catechins in it, besides it was distinguished by low acidity. All studied cultivars, especially ‘Alexandr Boyko’, are promising as raw materials for the juice industry.
