A Production Analysis of Dry Onion Powder from the Water Perspective

Nigeria’s dry onion production amounted to 1.38× 106 metric tonnes (t) in 2020. Roughly 50% of yearly do not reach the table. An option lies converting fresh onions powder mitigate postharvest losses. This study explores possibility producing from using a pre-tested locally fabricated direct-mode solar tent dryer. The outcome processing revealed product yield 8.09%, while there was no statistically significant difference between measured proximate contents and (t(28)=0.04, p=0.97, two-tailed; eta square=5.71 × 10-5). Overall, water neutral. About 4.5 cubic metres (m3) freshwater per tonne cleaned were needed during processing. Dry (from field table) use 31879.6 m3/t. Converting 40 - 60% national average (2000-2020) would consume 14.05 21.08 109 m3 freshwater. affirms that is technically feasible can help minimise losses Nigeria.
