Replacement of sucrose with sugar alcohols in high methoxyl pectin(HMP) jellies were studied. HMP jellies were sweetened with 100% sucrose, 75% sucrose and 25% maltitol, 50% sucrose and 50% maltitol, and 50% sucrose, 25% maltitol, 12.5% sorbitol and 12.5% mannitol. The effect of sugar alcohols in HMP jellies were investigted. There was only slight differences in sweetness intersity in HMP jellies. Color(p<0.05), texture(p<0.01) and preference(p<0.01) of 100% sucrose jelly were significantly higher than other jellies sweetened with sugar and sugar alcohols mixtures. Hunter`s L(lightness), a(redness), b(yellowness) values of 100% sucrose jellies and jellies substituted with maltitol up to 25% were not signignificantly different. But as the ratio and the number of sugar alcohols used for substition were increased, L, a and b values had been lowered signigicantly(p<0.01). Instrumental characteristics of jelly texture were examined. Hardness of 100% sucrose jelly sweetened with sucrose and 3 kind of sugar alcohols were higher than others(p<0.05). As substitution ratio was higher, springiness and chewiness of HMP jellies were lowered(p<0.01). Springiness of HMP jellies indicated positive correlation with general acceptance of sensory scores at 5% significant level. Brittleness, gumminess and cohesiveness in all types of jellies were not significantly different.
