Abstract

Non-centrifugal sugar (NCS) is an alternate sweetener produced without subjecting the sugar cane juice to centrifugal action. The quality of the NCS is greatly governed by physicochemical parameters viz. texture, color, non-reducing sugars, sucrose, etc. of the juice, which in-turn are dependent on “clarifier” used and “striking temperature” as the juice is undergoing clarification and evaporation processes. This paper demonstrates how multi-criteria evaluation (MCE) could be used to obtain the best clarificant-striking temperature combinations to produce quality NCS. The necessary data was generated by producing 12 NCS samples in the laboratory, with three clarification conditions, viz. no clarificants, hydrose, aloe-vera mucilage along with the striking temperatures ranging from 110 to 125 °C. As the NCS samples were being produced, the physicochemical quality parameters and process parameters were measured using appropriate measuring tools and methodologies. Finally, these measured quality parameters and production process parameters were subjected to MCE analysis to obtain the best clarificant-striking temperature combinations to produce quality NCS. Ranges of different physicochemical parameters as indicated by the experimental investigations are: non-reducing sugars (%) 50.11–72.23; moisture content (%): 3.28–12.27; Hardness (kgf): 0.55–41.94; process time from 45 to 51 min etc. MCE analyses carried using AHP and TOPSIS-based algorithm indicate that sugarcane juice subjected to striking temperatures of 115 °C and 120 °C with no clarificants will produce good quality NCS.
