- Abstract
During the cold season, mainly climacteric fruits such as apples, quinces and pears are consumed due to their content of vitamins, minerals and antioxidant compounds. The main purpose of this study was to compare the postharvest biochemical changes during storage in controlled atmosphere conditions of four apples varieties ('Topaz', 'Redix', 'Florina' and 'Rubinola') in two different years. Apples were harvested from the experimental orchard of University of Agronomical Sciences and Veterinary Medicine (USAMV) Bucharest, and stored under the same controlled atmosphere conditions, as follows: temperature (T): 1°C, O2: 3%, CO2: 0%, 2% and 5%, relative humidity (RH): 95%. The antioxidant capacity, ascorbic acid, total polyphenols and total flavonoids contents were monitored during entire controlled atmosphere (CA) storage period. For all analyzed apple varieties, the ascorbic acid content decreases in both years of analysis. Differences between the biochemical compounds concentrations was observed in the apples stored in CA conditions with CO2 compared to those stored without CO2. The influence of CO2 concentration on biochemical characteristics of fruits depends both the variety and the harvesting moment.
