Abstract:
The Results show insignificant differences within each location in, almost, all
parameters studied. The Average value of moisture was 12.44 % (w/w) and the ash
content was 2.45%. The nitrogen content was 038%, and the protein content was
2.53%. Specific optical rotation was -21.120. The acid equivalent weight and
glucuronic acid content were found to be 1701and 11.45 respectively. The number
average molecular weight was found to be 4.6730x105 g/mole, the Molecular
weight was found to be 5.637x105, 4.04911x105. Cationic composition studies
showed that Calcium was 6114 ppm followed by magnesium 2079 ppm, iron 177
ppm, cupper 95 ppm, manganese 38 ppm, sodium 20 ppm, zinc 5 ppm and
cadmium 0.111ppm in the decreasing order. The Sugar composition for Galactose
was found to be 4.25, 21.15
for Arabinose and8.75 for Rhamnose. Emulsion
stability indexes of four composite samples using three refined oils were 1.0925 for
groundnut, 1.101 and 1.2253 for sesame and corn oil, respectively. Antioxidant
activity studies showed that mean values were 18.3.mg/100g for TPC, 101.1mg/
100g and 25.95% for FARAP and ABTS, respectively. The Thermodynamic
studies of the three composite samples of the years 2012, 2013 and 2014 gave
average values of 1.46gcm3, 1.0087 cm3g -1, 0.396 and 0.6042, of average density,
partial specific volume of the gum solution, solvent water and the volume fraction
respectively. Chemical potential at different concentrations of the three composite
iiigum solutions were -2.1691x10-3 to -3.4879 x10-3 Jg-1, -2.4733x10-3 to -3.7833x10-
3
Jg-1 and
-3.1515x10-3 to -4.4781x10-3 Jg-1 respectively. The Second virial
coefficient was found to be 0.36x10-5. The ranges of the free energy of mixing of
the three samples were -0.7911x10-3 to -6.93644x10-3Jg-1, -0.20426x10-3 to -
6.81718x10-3Jg-1 and -4.83635x10-3,-9.8978x10-3 Jg-1, respectively.
