Abstract
Our purpose was to study the impact of controlled atmosphere (CA) on respiration of and changes in sugar content of diced onions. The onions were peeled, diced, washed, disinfected, and centrifuged before storage for 12 days under gas mixtures of 21% O 2 and 0% CO 2 (air), 2% O 2 and 0% CO 2 , and 2% O 2 and 10% CO 2 . Every 4 days, respiration rate and sugar content (total, sucrose, fructose, and glucose) were determined. Carbon dioxide-enriched atmosphere limited respiration rate and sucrose depletion, whereas the mere reduction of O 2 had no effect. Reducing sugar contents remained constant during storage regardless of the treatment.
