Purwoceng chemical characterization by FTIR spectrum and feasibility analysis of jelly purwoceng diversification with the addition of gelatine and carrageenan

Purwoceng is a Medicinal plant commodity that has very beneficial content to health. Purwoceng is known as Indonesian ginseng, which has almost the same efficacy as Korean ginseng. In this research, the purwoceng chemical group was analyzed using the FTIR spectrum. Aside from analyzing the purwoceng chemical group, feasibility analysis and diversification of the purwoceng jelly were also carried out with physical analysis. Purwoceng has high economic value but its use is limited to medicine, therefore research on the formulation of purwoceng jelly as a new innovation was carried out. The process of making purwoceng jelly is to add gelatin and carrageenan to purwoceng extract according to the formula namely gelatin 26, 28, 24, 22 grams and carrageenan 7, 8 grams stirred until evenly mixed. Citric acid then added stirred till homogeneous and formed a sticky mixture. Then lift and pour into the mold. The produced jellies were then organoleptically tested, their level of preference and water content. The results show that the more carrageenan added, the more water content. Whereas organoleptic test formula II are more preferred. The results of the characterization of the FTIR spectrum indicate that purwoceng has chemical groups such as alcohol, carboxylic acid, esters.
