ABSTRACT

The experiment was conducted with ten cultivars of sweet sorghum to know the
ethanol recovery and biochemical composition from stalk juice and grain. At physiological
maturity, maximum recovery of ethanol(9.12%) was obtained from the stalk juice of
NSS-208, which was found to be highest in total sugar (17.40%) and lowest in reducing
sugar (1.46%). The AKSSV-24 cultivar was also showed higher ethanol.recovery (9.03%).
The significantly superior grain starch content were reported by NSS-104 (72.5%) and
Keller (71.6 %) which ultimately turned to maximum yield of grain ethanol Le. 44.96 and
44.57 %respectively. Further biochemical analysis of grain revealed that maximum amylose
and amylopectin were found· in NSS-I04 followed by Keller, as well as NSS-104
found significantly superior in fat content (4.3%). Maximum content of phenol was
observed in BJ-248 (0.7%). Amongst all, grain malt of BJ-248 recorded highest diastatic
power (45.82. DUg-1) followed by NSS-04 (41.65 DUg-1). The analysis of bagasse
remained after extraction of juice reported that cellulose and lignin content was
maximum in bagasse of NSS-104 where as highest percentage of hemicellulose
was obtained in bagasse of Wray.
