Abstract:
In the present study rheological characteristics of khoa-pedas prepared using mechanized system based on the principle of piston press pressure technology consisting of a temperature controlled double jacketed hollow cylindrical barrel with piston system for applying pressure and conical die at the base for final compaction and shaping was done. Effect of three different process variables at different magnitude values, viz., temperature (26, 30, 34 °C), pressure (0.276, 0.552, 0.828 kg/cm2) and conical die geometry (1:1, 1:1.5, 1:2) on the rheological characteristics of khoa-pedas was investigated. Statistically (p<0.05) meaningful effect was observed on some rheological parameters of final product at different values of process variables. Results revealed that in mechanized formed khoa-peda hardness varied from 7.62 N to 51.96 N, adhesiveness varied from -0.608N to -0.092N, springiness varied from 0.089mm to 0.214mm, cohesiveness varied from 0.097 to 0.139, gumminess varied from 1.005N-mm to 5.974N-mm, chewiness varied from 0.103N-mm to 0.978N-mm and resilience varied from 0.031 to 0.041 respectively. Adhesiveness, gumminess and chewiness of khoa-peda samples, were significantly affected by mechanized process variables.
