✦ Synopsis

Gas-exchange models are often used to predict gas conditions inside modiÐed atmosphere (MA) packages of fresh plant products. Current models describing production of harvested plant products do not account for an CO 2 inhibition of a high partial pressure of on fermentation rates, whereas such CO 2 as inhibition on plant metabolism is often found. An existing gas-exchange model was modiÐed to include this inhibition. Gas-exchange data of mungbean sprouts were collected under various partial pressures of and and used O 2 CO 2 to validate the model. With the modiÐcation applied, production rates were CO 2 better described. Although production at low was reduced by high CO 2 O 2 partial pressures of no inÑuence was found on ethanol and acetaldehyde CO 2 , levels. The data found also indicate large di †erences between gas-exchange rates of di †erent batches of mungbean sprouts. It is suggested that microbial metabolism attributes substantially to total production rates found and that it CO 2 might explain these di †erences.
