Summary
Improper package design or temperature abuse during handling may cause fruits and vegetables in modified-atmosphere packages to be exposed to low, injurious O2 levels associated with the production of fermentation volatiles, quality loss and eventually product breakdown. A simple and reliable technique to detect low-O2 injury in packaged products at an early stage would reduce the risk of supplying inferior or unsafe produce to the consumer. The formation of ethanol, a common product of fermentation, has been correlated with low-O2 injury. A commercial ethanol biosensor, composed of a chromagen and immobilized enzymes: alcohol oxidase and peroxidase, and available as a test strip, was tested for its suitability to detect low-O2 injury indirectly. Sensibility of the method as well as results obtained with cut lettuce, cut broccoli, cut cauliflower, schredded cabbage and cut carrots are described.
