An experiment was conducted at Bangladesh Sugarcane Research Institute (BSRI), Ishurdi, Pabna, Bangladesh. In this study, biochemical composition, enzyme activity and some chemical parameter of sugarcane juice in the varieties Isd-16 and Isd-28 were investigated. Isd-28 showed higher amount of brix (20.85%), pol (18.53%), fiber (19.93%), ash (6.95%), minerals (Na 1.36 & K 3.12 gm/100 gm ash) and lipid (0.058%) than that of Isd-16. Other compositions such as reducing sugars (0.096%), commercial cane sugar (12.55%), moisture (88.97%), protein (0.328%) and vitamin-C (0.00351 gm/100 gm juice) were lower in Isd-28. Amylase enzyme activity (44.44 unit/ml) and cellulase enzyme activity (7.15 unit/ml) were higher in Isd-28 but invertase enzyme activity (10.88 unit/ml) was lower than that of Isd-16. Purity (91.34%) and extraction percentages (54.63%) were higher in Isd-16 whereas, recovery percentage (11.17%) was lower in the juice of Isd-16 variety than that of variety Isd-28 of sugarcane. Most of the biochemical compositions analyses were higher in Isd-28 than that of lsd-16. Reducing sugars were less in Isd-28 variety indicating less invertase activity.
