From this study the best operating condition for glucose synthesis from jackfruit stone flour using the enzyme
method was obtained. The method used in this study referred to the synthesis of glucose from cassava starch and
fresh cassava [9,10]. Sugar content obtained from enzyme method was 19.43 % with the volume ratio of glucose
was 33.15 %. The synthesis of glucose using acid method produced glucose content around 17.36 % at pH 3.5 with
the volume ratio of glucose around 43.23 %. The yield of dry starch to glucose level was 77.72 %. From cassava
raw material, (15 to 25) % yield of cassava starch was obtained and from dry starch produce (80 to 95) % yield of
glucose syrup [8].
