Physio-biochemical changes of fresh-cut pear treated with different concentrations of calcium lactate
The effective of 0.5%, 1.5%, 2.5% calcium lactate in inhibiting physio-biochemical changes of fresh-cut pear stored at 10 ℃ were studied. The result indicated: the treatment of 1.5% calcium lactate dipping obviously enhanced SOD and CAT activities, inhibited POD activity, the membrane lipid permeability and the increasing of H2O2 and O-2·, and reduced the respiration rate. It suggested that the treatment of calcium lactate can slow the physio-biochemical metabolism and extend the self-life of fresh-cut pear.
