Effects of dynamic controlled atmosphere by respiratory quotient on somen quality parameters and volatile profile of 'Royal Gala' apple aftern long-term storage

摘要

The effects of dynamic controlled atmosphere (DCA) storage based on chlorophyll fluorescence (DCA-CF) and respiratory quotient (DCA-RQ) on the quality and volatile profile of 'Royal Gala' apple were evaluated. DCA storage reduces ACC (1-aminocyclopropane-1-carboxylate) oxidase activity, ethylene production and respiration rate of apples stored for 9 months at 1.0 degrees C plus 7 days at 20 degrees C, resulting in higher flesh firmness, titratable acidity and lesser physiological disorders, and
