Comparative Study of Dextrose Production from Locally Sourced Cassava, Tigernut and Yam
Abstract: Starch was extracted after sedimentation from seven samples, TME 419, TMS 30572, Provitamin, Tigernut, Boko, Mumuyi and Onitsha. The first three samples were cassava varieties while the last three samples were species of yam variety Dioscorea rotundata. The extracted starch were gelatinized and hydrolyzed enzymatically to produce 250ml of dextrose from each sample. From spectrometer analysis it showed that Mumuyi dextrose has the highest glucose concentration of 0.72mg/ml when compared …

Chemical Synthesis and Industrial Applications of Catechu
Abstract: Kattha is acquired by crystallization in cold from the water extractives of the heartwood of Acacia catechu. The main constituents of the red heartwood are catechin and catechu tannic acid along with small proportion of brown coloring matter. It also contains tannin, flavotannin, gallotannin, hloratannin etc. (+)-Catechin is a constituent, which decreases the action of some hormones; hence “tyronorman” injected with thyroxin terminates the upsurge in basal metabolism. It has …
