Karakterisktik Polisakarida Larut Air (PLA) Umbi Bengkuang (Pachyrhizus erosus L.) dari Berbagai Metode Ekstraksi

Abstract

The aim of this research was to determine the effect of the addition of water and various extractions method on the chemico-physic properties of water-soluble polysaccharide. This study used a completely randomized design (CRD) with two factors i.e. the addition of water (0,5 part, 1 part, 1,5 part and 2 part) and extraction method (water, yeast and mold). Observed parameters were moisture content, protein content, fiber content, yield, glucose content, reducing sugars, total sugars, viscosity, dextrose equivalent, polymerization degree, soluble ability and form of granule of PLA yam bean. The results showed that the addition of water had highly significant effect on moisture content, protein content, fiber content, yield, glucose content, reducing sugars, total sugars, viscosity, dextrose equivalent, polymerization degree and soluble ability PLA. The extraction method had highly significant effect on moisture content, protein content, fiber content, yield, glucose content, reducing sugars, total sugars, viscosity and soluble ability PLA and had significant efffect on dextrose equivalent and polymerization degree PLA. Interaction of the addition of water and extraction method had significant effect on moisture content PLA and had no significant effect on protein content, fiber content, yield, glucose content, reducing sugars, total sugars, viscosity, dextrose equivalent, polymerization degree and soluble ability PLA.
