Extraction And Analysis Of Characteristics of Starch From Sago Hampas

Yuni Rahmawati, Alfi Asben, Kesuma Sayuti

Abstract


Sago hampas is a by-products of the sago processing industry which has not been handled properly and has unique material because it is a strachy lignocelluloses material with a starch content of 50-70%, but it has a weakness because it it tightly bound in the lignocelluloses matrix. This research aimed to determine the appropriate extraction method for sago hampas starch and characteristics of starch from sago hampas.This research used two extraction methods, hydrothermal using autoclave and ultrasonification using ultrasonic bath. The results showed that the best extraction method was using ultrasonification for 60 minutes without temperature treatment with a sago hampas concentration of 4% (w/v), obtained a water content of 6.35%, yield 7.69%, density 0.83 (g/ml), pH 5.59, visicosity 967 BU, solubility 11.13%, swelling power 14.46 g/g, amylose 17.75% and amylopectin 82.25%.
