Abstract

The xylan content of corn cobs reaches 12.4 - 12.9% which can be converted to xylitol [1]. Xylitol products significantly reduced the population of Streptococcus mutans in saliva compared with fluoride [2]. The objective of this study was to convert xylan from corncob waste into xylitol as an additive in wuluh belimbing jelly. Xylan corn cob is fermented using Candida tropicalis. Furthermore xylitol from corncob tested the effectivity of antibacterial Streptococcus mutans grown in oral cavity that can damage enamel on tooth. The xylitol extraction method of corncob using aqueous sulfuric acid is 0.25; 0.5; 0.75 and 1.0%. The extraction time was then varied from 15, 30, 45, 60, 75 and 90 min. The results showed xylitol compound from corn tuna waste was highest at 0.25% sulfuric acid concentration with 30 minutes hydrolysis time of 249.7 ppm and the lowest at acid concentration 0.75% and hydrolysis time of 90 minutes ie 5.6 ppm . The results showed xylitol compounds from corncob waste that all xylitol concentrations showed a negative sign.
