EFFECTS OF CHITOSAN ON FRUIT SHELF-LIFE AND QUALITY OF STARFRUIT UNDER PASSIVE AND ACTIVE PACKAGING
The objectives of this research were to study 1) the effects of chitosan concentrations, 2) packaging volumes, and 3) interaction between chitosan concentrations and packaging volumes on starfruit shelf-life and qualities under passive and active packaging tecnologies. A completely randomized design with two factors were assigned onto passive- and active-packagings. The first factor was surface coating of 0, 1, 2, and 3% chitosan. The second factor was chamber volume of 1.5, 3.0, 4.0, and 5.0 L, assigned onto passive- and active-packagings. This research showed that (1) under both active- and passive-packagings, chitosan statistically did not affect starfruit shelf-life compared to the control. However, plastic wrapping which is a common starfruit postharvest handling in the markets has to be avoided due to environmental reasons, 3% chitosan proofed to be the best treatment; (2) Postharvest handling of starfruit with 3% chitosan under active-packaging showed the best treatment by prolonging starfruit shelf-life and less weight loss with other fruit qualities unaffected; (3) Postharvest handling with 3% chitosan applied as a surface coating was suited for starfruits under a passive-packaging of any volumes.
