Should I Worry About Ethylene Gas?
University researchers findings imply that there is no ‘safe’ level of ethylene that does not cause a deleterious effect on postharvest life.
If 5 PPB is assumed to be the lowest possible ethylene concentration that can be achieved in a postharvest situation, then holding any non-climacteric fruit and vegetable in 5 PPB ethylene will generate 100% of its possible postharvest life. The percentage loss in postharvest life at any higher ethylene concentration can then be calculated from the regression equations. The percentage loss in postharvest life at 20 degrees C for the 7 non-climacteric produce examined in wills et al. (1999) ranged from 25 to 46% postharvest life was lost
