Abstract

Changes in softening and respiratory enzymes activity and in other related physicochemical parameters were studied during ripening of starfruit Averrhoa carambola cv B10. B-Galactosidase and pectin methylesterase activity increased during ripening of starfruit. The increase was correlated with changes in fruit softness as well as in the level of soluble polyuronides. Respiratory enzymes studies showed that NADP-malic enzyme activity reached maximum at day 20 and than reduced on the following days. The activity of PEPCase however fluctuated throughout the storage period. The physicochemical changes such as the skin color total soluble solid water loss and titratable acidity also registered an increase during ripening. Tissue pH remained unchanged initially but decreased later during ripening
