Evaluation of The Effect of Ion Exchange Technique and Temperature on Physicochemical Properties Raw and White Sugar Solution

Sugar with low price in compare to the amount of calories, producing is as one of the important nutrients in the daily diet especially for poor communities. On the other hand in the sugar industry due to consumer demand for high quality and variety in products ion exchange technigues are used wich affect the chemical properties of sample. So the aim of this study was to investigate the physicochemical properties (Brix, pH, color and electrical conductivity) of raw and white sugar by a cationic resin, heating for two hours in 70 ◦C and the anionic resin. The results showed that the brix of samples was decreased by using resin. The results also showed that cationic resin were effetive in decreasing the pH value and increasing the parameter by using anionic resin. In addition reduction in color of both sugar solution was observed by resin. In the case of white sugar color reduction was in direct contact with pH and white sugar slight increase in color was observed after using anionic resin. On the other hand the results indicated the electrical conductivity was increased by cationic resin. So the treatment by cationic resin and heating in 70 ◦C had the highest electrical conductivity.
