Based on the physicochemical characteristics and synergistic interaction of konjak gum,carrageenan,xanthan gum and locust bean gum,by means of the orthogonal experiment,the optimum formulation of colloids was determined as follows:konjak gum 0.1%,carrageenan 0.18%,xanthan gum 0.06%,locust bean gum 0.06%.According to the health function of these four raw materials,the optimum addition amount of extract was:immortal grass 6%,prunella vulgaris L 5%,honeysuckle 6%,liquorice 0.6%.Through the research,compound health immortal grass jelly with unique taste and steady quality was developed.
