Effect of centrifugation on temperature of sesame past

Abstract

The sesame seeds were mechanically cold pressed at temperature below 45℃ then centrifuged.  No chemicals were used.  The temperature during centrifugation of sesame paste was recorded.  Temperatures in less than one hour elevated to 148, 273 and 315℃ in 1,200, 1,800 and 2,400 G-force centrifugal acceleration, respectively.  Since the centrifugal accelerations during processing will be cut to 1200 G-force in about 35 min, 1800 G-force in 20 min and 2400 G-force with the time 10 min, the maximums temperatures raised about 100℃.  Linear and quadratics regression model were fitted to data.
