Abstract: Chitosan is a very potential biopolymer for the beverage industry because of its chemical and
biological properties. In this study, chitosan was obtained from the dried exoskeleton of blue
crab (Portunus pelagicus) with a recovery yield of 55.35% and was utilized in the production of
jackfruit beverage. Determination of the free radical scavenging assay (FRSA) of chitosantreated
jackfruit beverage kept for five days at ambient and refrigerated condition was
undertaken. The FRSA of chitosan-treated beverage increased as the level of chitosan increased
regardless of the storage conditions employed. The jackfruit beverage with 3g chitosan and
stored in refrigerated condition had the highest antioxidant activity from 421.94 to 470.71 umol
TE/100g after five days of storage. Increasing the chitosan level to 4g, a lower FRSA was noted
in samples stored at ambient and refrigerated conditions. |
