The main objective of this research work is to determine the Physicochemical Properties of Sugar Produced from Sugarcane at new Halfa Sugar Factory, Sudan, for season 2017/2018. For this purposes, three types of Sugar products (S1 , S2 , S3) named as ( Dark , Colored and White) at three periods (T1, T2, T3) corresponding to (November , January and March), respectively. the parameters include: Total soluble solids (Brix) using Automatic Digital Refractometer, the sucrose % (Pol) using Automatic digital Polarimeter. Reducing sugars by ICUMSA Method GS1/3/7-3 (2005), Carbonated and sulphated Ash Nitrogen content , Moisture content, Viscosity and pH values. The results revealed that, the average levels of Total Soluble Solids (TSS), Sucrose, Sweetness, Reducing sugars, were 99.7%, 98.45%, 98.68%, 0.185%,respectively, Traces of ash were found in sugar samples, they did not exceed 0.04. Moreover, the Nitrogen content not exceeding 0.15 in sugar samples, The colour ranged between 288 , 240 and 65 (IU) for the dark , colored and white sugar respectively, the relative viscosity is ranged between 0.810 – 0.908. The kinematic (absolute) viscosity of the sugar solutions ranged between 1.804 and 1.908, the pH values of the sugar solution were found to be in the range of 6.90-6.99, and the moisture content is ranged between 0.16 – 0.23% for the three samples of sugar.
