Material Losses and Garri Recovery Rate during the Processing of Varieties of Cassava into Garri

Materials losses and garri yield during garri processing on different cassava varieties; TMS/92/0057, TMS/30572, TME/419 and Vitamin A: 01/1368 were conducted. The results showed that there were variations within the different processing unit as well as the cassava varieties during garri processing. Losses were recorded highest at grating, dewatering and fermentation processes with the values of 9kg from TMS/92/0057 recording the highest loss, 8.5kg from Vitamin A: 01/1368, 7.7kg from TMS/30572 and 7kg from TME/419. On roasting processes, TMS/30572 had 3.2kg loss, Vitamin A: 01/1368, had 2.5kg loss, while TME/419 and TMS/92/0057 had 2kg loss respectively. Material losses at peeling showed that Vitamin A: 01/1368 recorded 4.5kg loss being the highest, TMS/92/0057 and TME/419 recorded 3kg loss each, while TMS/30572 recorded 2.5kg loss. Sifting losses indicated that vitamin A: 01/1368 and TME/419 had 1kg loss each, whereas TMS/30572 had 0.8kg loss and TMS/92/0057 had 0.5kg loss. Overall material loss for each cassava variety based on fresh weight of 20kg and maturity age of 14 weeks was determined, which vitamin A: 01/1368 recorded the highest loss of 16.5kg, TMS/92/0057 had 14.5kg loss, TMS/30572 had 14.2kg loss and TME/419 recorded 13kg loss. The total garri yield from each variety was also determined with TME/419 having 7kg yield, TMS/30572 had 5.8kg yield, TMS/92/0057 had 5.5kg yield and Vitamin A: 01/1368 recorded 3.5kg yield. Percentage losses from the tested varieties showed that vitamin A: 01/1368 had the highest percentage of 82.5% loss, TMS/92/0057 had 72.5% loss, TMS/30572 had 71% loss and TME/419 recorded 65% loss. Percentage yield of garri was also determined on the cassava varieties, this showed that TME/419 had 35% yield being the maximum, TMS/30572 had 29% yield, TMS/92/0057 had 27.5% yield and Vitamin A: 01/1368 recorded 17.5% yield.
