Analysis of mechanical properties, biochemical composition and technological parameters of grape (Vitis) raisin varieties in conditions of Uzbekistan

Abstract

This article describes the agrobiological characteristics of grapes (Vitis) raisins (Hermione) grown in Uzbekistan, the mechanical and biochemical composition of the grape and the technological - raisin (Hermione) indicators of large grape varieties. The highest sugar content in Hermione was found in the Sultani variety at 70.9%, while in the Kara Djandjal variety it was also insignificant compared to control (64.6%). The highest organoleptic value of hermione product made from raisin varieties of grapes was recorded in Sultani and Hussaine nutmeg varieties. It was observed that the tasting value of hermione products made from grapes of this variety is the highest - 8.0 and 7.9 points, respectively, for varieties.
