Abstract

Jaggery is a solid unrefined, non- centrifugal cane sugar (NCS) with unique colour, flavor and aroma obtained from crushing of cane and evaporating of sugarcane juice. In this paper vacuum pan evaporation method were used sugarcane juice boiling at vacuum pressure (Vp : 500-700 mm of Hg), time (t:60-90 min) and temperature (T:100-1200 C). The quality attributes of jaggery developed from vacuum pan evaporator were investigated at different process variables. The developed jaggery were analyzed for physiochemical. Results showed that TSS (0 Brix) and Hardness (Hd) increased with increase in vacuum pressure and time, whereas moisture content percentage (%) and water activity (aw) decreased with increase in vacuum pressure and time at variable temperature of 1100 C. Fuzzy logic method was used to evaluate the sensory characteristic of prepared jaggery.
