Abstract
Domestic production does not adequately meet the high national demand for sugar in Indonesia, prompting the exploration of alternative raw materials for liquid glucose production. Elephant foot yam (Amorphophallus campanulatus), a local plant with a high starch content, holds significant potential as a raw material for producing liquid glucose. This study investigates the effect of varying saccharification times (2–6 hours) and stirring speeds (200–400 rpm) on the liquid glucose’s glucose and moisture content obtained from the enzymatic hydrolysis of elephant foot yam starch. The hydrolysis process began with starch extraction from elephant foot yam, followed by liquefaction using α-amylase and saccharification using glucoamylase. The results showed that increasing saccharification time and stirring speed led to a proportional increase in glucose content and a decrease in moisture content. The highest glucose concentration, 27.5 °Brix, was achieved at 6 hours of saccharification with a stirring speed of 400 rpm, although this value did not meet the Indonesian National Standard (SNI) minimum of 70 °Brix. The moisture content ranged from 7.229% to 18.139%, within the maximum allowable limit based on SNI 01-2978-1991. These findings indicate that elephant foot yam is a promising alternative raw material for liquid glucose production, with saccharification time and stirring speed being as key influencing factors. Further research is recommended to extend the saccharification time to achieve glucose levels that meet industrial standards.
