The present study was conducted to assess the suitability of blends of two sweet potato (creamand yellowflesh) varieties and maize flours in the preparation of crunchy snacks. Each of the sweet potato varieties was prepared into flour and separately blended with 0, 30 and 50% of maize flour. The blends were evaluated for proximate composition, mineral content, vitamin content, anti-nutrient fac...

Sweet potato chlorotic stunt virus (SPCSV) was first detected in China in 2010, and several partial sequences have been determined for Chinese SPCSV isolates. This report describes the complete genome sequences of two SPCSV isolates from the Guangdong and Jiangsu provinces and will be valuable for understanding the characteristics of SPCSVs in China.

Sweet potato, Ipomoea batatas (L.) Lam., is an important food and industrial material crop throughout the world. It is also an alternative source of bio-energy as a raw material for fuel production. China is the biggest sweet potato producer in the world. Biotechnology offers great potential for improving disease, pest and stress resistance and nutritional quality of sweet potato. In the past d...

Life-cycle assessment (LCA) was used to evaluate the energy efficiency and environmental impacts of sweet potato-based bioethanol production. The scope covered all stages in the life cycle of bioethanol production, including the cultivation and treatment, transport, as well as bioethanol conversion of sweet potato. Results show that the net energy ratio of sweet potato-based bioethanol is 1.48 ...

Sweet potato is infested by root-knot and reinform nematodes. Root-knot nematode infestation in sweet potato is studied in detail. A number of resistant varieties are released in sweet potato from USA, Japan and China. A number of germplasm accessions and cultivars/ varieties were found resistant to the nematodes in Peru. Studies carried out by the authors indicated that sweet potato germplasm ...
