| Abstract:
A 4 day preconditioning at 1C was found to significantly reduce weight loss of carrots when placed into simulated shelf conditions of 13C, >95% relative humidity. Anatomical investigation revealed that the preconditioning enhanced deposition of suberin on the surface of the periderm and lignification of subsurface cell layers. These two changes are suggested as possible mechanisms for reduction of weight loss and discoloration of the carrots which occur under shelf conditions. These results indicate that fresh market carrots could show significant benefits at the retail level from routine low temperature preconditioning. | |
