Kolodyazna V.S., Leonova S.V., Danilov P. A.

Depending on changes in physical-chemical and biochemical indicators of quality apples summer - autumn varieties: Autumn stripes and Antonivka installed on the duration of storage. Regression equations that characterize these plots were obtained. Based on comparative analysis of quality chilled and frozen apple varieties: Autumn stripes and Antonivka found that a change in the activity of terminal oxidases, the contents of titratable acidity and pH are observed significant differences s between chilled and frozen samples of apples were stored for seven months. Changes in total content of mono-and disaccharides and ascorbic acid occur in an identical fashion regardless of class and method of refrigeration storage of fruits.
