Six guar genotypes were used for this study The results revealed chemical compositions of endosperm of the guar seed are as : 4.8-8.7 % moisture, 3.5-5.5 % protein, 0.5-0.9 % fat, 0.5- 1.3 % ash, 1.4- 2.0 .% fiber and 83.3-87.5% carbohydrates. While physical characters are:1.2337 refractive indices, 0.20-0.47 relative viscosity (H2O as solvent),0.37-.56 relative viscosity (4% NaCl as solvent), 5.0-7.0 pH, 0.035-.0.050 optical density and +28 to +76 specific rotation ash compositions of endosperm are potassium: 57 – 79 mg/Kg, sodium 242 – 755 mg/Kg, calcium 11 – 24 mg/Kg, iron 49 –287 mg/Kg, magnesium 0.2 – 0.09% and phosphorus 15 - 22 % . The total available carbohydrates as mannose and galactose were ranged 67-73% and 28-33%, respectively. Ratio of mannose to galactose is 2:1. Copyright@ International Science Community Association
