Effect of Different Colors of Gum Arabic Acacia Senegal on its Physicochemistrcal Propetries
2018
Overview
Samples of Gum Arabic (Acacia Senegal) different colors were collected from different locations and tree ages, North, west and middle Kordofan state. Sudan. Sorted to four, color categories Mixed, Glassy, Pink and Reddish. Samples were prepared by milling and purification. Samples subjected to Physicochemical investigations' and tests carried out and most properties were determined, results obtained were( the mean value of triplicates) indicated no considerable differences between the four samples, as follows:, moisture content, 11.2%, 11.1%, 11.1% and, 11.4% respectively. PH value 4.2, 4.3, 4.07, and 4.21 respectively, Electric conductivity EC, 2.41, 2.40, 2.39, and 2.44. Specific gravity, 1.0078, 1.0057, 1.0599 and 1.0110. Specific optical rotation readings obtained were all the same, table No.: 7. the mean value was (-31.9). Refractive index degrees were all the same (1.3453), solubility revealed values were almost the same results, 99.5, 99.45, 99.50, 99.60. Viscosity, 20.8, 20.0, 19.9, 20.8. Emulsifying stability, 0.9744, 0.9989, 0.9685, 0.9600 CP respectively, nitrogen content 0.368, 0.366, 0.369, 0.363 and protein content = (N2 *6.25),total ash content in the study also showed no considerable differences between the four samples 2.61,%, 2.62 ,%, 2.58%, and 2.62% or even with the mixed one. On the other hand Ash content was measured. All results readings were in the acceptable range of FAO/WHO ANS SSMO specifications and of the most workers. Comparing most of the results and parameters investigated no considerable differences between the four samples of the different color degrees, mixed, glassy, pinky and reddish, regarding the mixed color sample as blank as (it represents) the other three samples. So from the results obtained we can say no significant or considerable effect for different gum colors on physicochemical and functional properties.
