Název v původním jazyce

Release of anaerobic metabolites from intact sweet cherries stored i low oxygen atmospheres

Popis výsledku v původním jazyce

Acetaldehyde and ethanol accumulated in the flesh of cherries and also permeated through the skin into the surrounding atmosphere. A permeability constant for both fermentation metabolites was calculated for the whole storage period. The permeability constant was 0.145 x 10-4 mikro g/kg/h for ethanol, and 20.9 x 10-4 mikro g /kg/h for acetaldehyde, after 33 days of storage in anaerobic conditions and following 19 days in cold storage with normal air. The levels of these metabolites in the cherry flesh after 33 days of storage were 2.21 mg/l for acetaldehyde and 1.58 mg/l for ethanol. For other treatments, such as ultra-low oxygen and controlled atmosphere, levels were about half these values. Fruit stored in 1.0% O2 + 7.0% CO2 had approximately identical ethanol levels to the ultra-low oxygen fruit and no additional effects of higher CO2 levels on the fermentation metabolism were detected. High CO2 levels in the atmosphere maintained fruit firmness more effectively than other treatment
