Characteristics of Licorice Jellies using a Water Extract of Licorice Root and Various Gelling Agents

다양한 젤화제와 감초추출액을 이용한 감초젤리의 특성

This study was conducted to investigate the usefulness of a hot water extract of licorice root as a source for production of healthy food. The electron donating capacity of the hot water extract of licorice root was very strong. This activity decreased by $6.9\%$ after keeping it in 5 days of cold storage, but it was not significantly different. Ten types of licorice jellies were prepared, using agar, agar-pectin, agar-cellulose, 2 different proportions of agar-pectin-cellulose as a gelling agent, and 2 levels of sugar. Among the 5 jellies containing $10\%$ sugar, the elasticity and overall acceptance of the agar jelly obtained the highest sensory score, but the color and flavor were not affected by the type of gelling agents. As the sugar concentration increased to $15\%$, the elasticity of the agar jelly was also evaluated as being the best one among the 5 jellies, but the overall acceptance was not significantly different from the others.
