Abstract

The physical and chemical properties of coconut water and its concentrates were studied. The specific gravity, viscosity, refractive index, total solids, Specific conductance, total ash and optical rotation increased as the coconut water was concentrated; surface tension and the rate of inversion decreased as the sample was concentrated. It shoved a weak absorption peak at 300-250 mu. It reacted positively with reagents like lead acetate, Na0H, NH2OE, Ba(OH)2, borax, CaCl2, picric acid, tannic acid, lth testing solution of Fehling's aid with ∝-napthol in chloroform.

A substance with the properties of a rum was obtained by alcohol precipitation. The average yield of gum obtained was 0.43 gm. per 100 ml coconut water. The separated gum shoved presence of carbohydrates, reducing auger and protenaceous components. Its solution gave an absorption spectrum at 300-250 nu. Its total ash was 38.56 %
