Pengaruh Prose Fraksinasi Pati Sagu Terhadap Karakteristik Fraksi Amilosanya

Abstract

The objective of this research is to analyse the effect of the starch suspension temperature and the I-butanol volume as complexing agent 10 the characteristic of amylose of sago starch fraction. In the fractionation process, the yield of amylose fraction increased in line with the increasing of starch suspension temperature and increasing of I-butanol volume as compJexing agent. The different condition of fractionation process produced amylose fraction which was different in molecular weight distribution (fraction-I and fraction-2). The functional properties of amylose fraction with fraction-2 dominant (solubility, swelling power and freeze-thaw stability) are relatively lower compared to the amylose fraction with fraction-dominant. On the other hand the clarity and oil retention capacity (ORC) value are relatively higher.
