Impact of Storage Methods and Duration on Sugar and Starch Content and Ethanol Yield of Sweet Potatoes [Ipomoea batatas (L.) Lam]
Abstract: Previous studies have shown that ‘industrial’ sweet potatoes can be an excellent feedstock for ethanol production as compared to corn, sorghum and other potential feedstocks. However, starch content can be affected by cultivars as well as storage conditions. Ideally, it is practical that sweet potato storage roots be processed for ethanol production as close to harvest as possible, but this may not always be the case and some amount of …
