Abstract:
The aim of this study was to prepare an anti-acid from Tamarindus -indica fruit pulp and to determine some of the physicochemical characteristics of tamarind fruit pulp and the product (anti-acid).
Samples of tamarind fruit were collected from North Kordofan (Elobeid) ,
the preparation of tamarindus acid was carried out using ion exchange chromatography. then , by reacting of tamarindus acid with magnesium bicarbonate the magnesium anti-acid was prepared.
The study of the physicochemical properties of tamarind pulp showed that, the moisture content was (22.54%) , ash content : (3.69%) , pH : (2.78) ,viscosity : (12 cp) , colour : (28) and specific rotation : (+40) .
The physicochemical properties of the prepared anti-acid were, the moisture content : (22.34%) , ash content : (48.38%) , pH : (6.19) , viscosity : (7.5 cp) , colour : (5 ) and specific rotation : (+0.5) .
The minerals content measurement using ICP/OES spectroscopy showed that the mineral contents of the pulp sample were Sodium : (83.905 ppm) , Magnesium : (828.588 ppm) and Calcium : (489.36 ppm) . The mineral contents of the prepared anti-acid were Sodium : (15712 ppm) , Magnesium : (16.431 ppm) and Calcium : (55.386 ppm) .
