Extraction and Characterization of Galactomannan from Nipa Palm Fruit (Nypa fruticans W.)

The main objective of this research was to characterize the galactomannan from Nipa palm fruit. galactomannan, a water-soluble heteropolysaccharide extracted nipa fruit with different condition. Different condition referred used without drying as fresh (GalFN) and which is done by dry (GalDN). Extraction method aqueous extraction followed precipitation ethanol. Polysaccharide studied in detail for its chemical functional characterization. result suggests that (GalFN GalDN) does not have significant impact (p>0.05) on yield, solubility (25°C 80°C) oil-holding capacity (OHC), yet it has effect (p<0.05) whiteness degree water-holding (WHC). physicochemical properties GalFN GalDN obtained respectively are follows: yield (6.34% 6.13%), (78.20 70.10), (34.93% 35.73%) at 25°C (71.13% 72.73%) 80°C, WHC (295.03 316.97 g water/100 gum), OHC (81.70 86.20 oil/100 gum). It concluded between there were significantly differences degree, water holding capacity, viscosity Concentration Nypa gum 1% 2%.
