Abstract

"The aim of this research was to observe the effect of different drying methods to the quantity and quality of carotenoids extracted from Red Melinjo peels. Carotenoids are plant pigment that grow in popularity due to its functional property, but easily to degrade in high temperature conditions. In this research, Red Melinjo peels were used as the raw materials. Preliminary study about ideal solvent for extraction and saponification requirement were conducted. Mixture of acetone:Hexane (1:1, v/v) was selected as the ideal solvent for extraction and extraction without saponification was preferable. Three variations of drying methods, which were oven drying (45 oC and 60 oC), sun drying and freeze drying, were conducted. The quality of carotenoids was determined by total color difference on the powder and the extract. Quantity of carotenoids was calculated by total carotenoid content. Oven drying 60 oC is the best drying method, since it gives the minimum color differences on powder sample (∆E = 17.06) and the highest yield of carotenoids during extraction (377.99 µg/g DM). For further research, identification and quantification of carotenoids compositions using LC/MS and also rate of dying measurement are suggested.
