Replacement of sucrose with other sweeteners and high methoxyl pectin in low caloric pectin gels

대체 감미료와 high methoxyl pectin을 이용한 저열량 pectin gel의 제조

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 100fl 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). Instru-mental 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, gum-miness and cohesiveness in all types of jellies were not significantly different.
