Производитель: "LAP Lambert Academic Publishing" Gum Arabic from Acacia senegal (Wild) has been fractionated by a foaming method into two fractions, high protein fraction (HPF) that represents 30% of the gum and a low protein fraction (LPF) which represents 70% of the gum. A comparative study between the crude gum and the two fractions carried out in the scope of their physio-chemical properties. A proximate analysis of the crude gum and the two fractions(HPF and LPF respectively) revealed that, the moisture content(10. 11, 10. 04 and 10. 05) and specific rotation( -31,-30 and -30) were insignificantly different whereas ash%(3. 7, 3. 33 and 3. 03), acid insoluble ash%(0. 3, 0. 135 and 0. 145), acid insoluble matter% (0. 18, 0. 55 and 0. 58) and pH ( 4. 49, 4. 47 and 4. 25) were significantly different . The nitrogen (0. 28, 1. 51 and 0. 007) and protein content (1. 85, 10. 01 and 0. 05) and the intrinsic viscosity (17, 44. 5 and 6 cm-3/g) were, highly, significantly different. Mineral composition of crude gum, fractions HPF and LPF revealed that LPF had the... ISBN:9783659496851 Издательство: "LAP Lambert Academic Publishing" (2014)
