PERANCANGAN EKSTRAKTOR INULIN DARI UMBI DAHLIA

Abstract

ABSTRACT

Limitation of the scale production become an obstacle in a process of inulin production. The aim of this research is to design an extractor which could be used in a larger sacle of inulin production. Extracting inulin from starch was done by adding water as solvent in ratio 1 : 2 at 70⁰C with a variety of heating time 15, 30, 45, and 60 minutes. After the extraction was done, the inulin solution was filtrated and allowed to stand at 10⁰C for 72 hours to obtain the wet inulin. Then, the wet inulin was dried in the oven to remove the water content thus obtained dried inulin. The result showed acquisiton of inulin per mass of dry starch at 15, 30, 45, and 60 minutes was 6.78%, 7.45%, 9.33% and 11.12%, respectively.
