Pembuatan Permen Jelly dari Karagenan dan Konjak dengan Aplikasi Prebiotik Xilo-Oligosakarida

Abstract

The functional food’s consumption is growing rapidly. One of the functional ingredients is Xilo-oligosaccharides (XOS). In this study XOS was added to jelly candy which used carrageenan and konjac as gelling agent. Carrageenan and konjac was used as alternative gelatin substitute. The objective of this research is to study the influence of gelling agent (carrageenan, konjac, mixture of carrageenan and konjac), ratio of carragenan and konjac (1:1, 2:1, 3:1) and concentration of xilooligosaccharide used (3%,4%, 5%) to the physical and sensory characteristics of jelly candy. This research is divided in two steps, preliminary and main research. Preliminary research consists of formulation and selection of the best formula for the main research. The best formula is formula with 1.5% gelling agent, 20% sugar, 5% glucose, 0.2% citric acid, 0.1% flavor, 0.001% colorant, 73.2% water and sugar coating. Main research consists of texture, sensory, proximate, and XOS content analysis. The optimum jelly candy from texture and sensory analysis is jelly candy with mixture of carrageenan and konjac (1:1) and 5% XOS. The jelly candy has the hardness of 166.28 gf, elasticity 1.00, and stickiness 132.95 gf. The result of proximate analysis showed that jelly candy has 10.37% water content, 0.35% ash content, 1.00% fat content, 0.96% protein content, and 87.32% carbohydrates content (by difference). The XOS anlalysis show that the jelly candy contain 15.17% XOS.
