Cassava (Manihot esculenta Crantz) is one of the most important food crops grown in the tropical regions of the world. Even though cassava is also cultivated and consumed in southern China there is little knowledge of the composition of the cassava grown here. Therefore 16 cassava germplasms collected from Hainan Province in China were used in the present work to determine the proximate composition amino acid mineral and hydrogen cyanide contents of their roots. The results showed significant differences among the cassava germplasms. The cassava germplasms contained 85.56 - 90.50 g/100 g carbohydrate 0.03 - 1.28 g/100 g crude lipid 1.41 - 4.74 g/100 g crude protein 2.90 - 8.60 g/100 g moisture and 2.89 - 4.38 g/100 g ash. The mineral contents were 62.89 - 467.36 425.01 - 1474.71 and 070 - 7.95 mg/kg for Ca Mg and Pb respectively; and 1523.08 - 4749.46 75.57 - 766.33 9.57 - 282.83 4.48 - 26.69 0.75 - 373.60 and 10.43 - 29.04 mg/kg for K Na Zn Mn Cu and Fe respectively. The HCN content ranged from 0.32 - 1.53 mg/g. Among the 16 cassava germplasms ZMH1071 ZMJ615 and SC12 yielded higher carbohydrate content and lower HCN content making them suitable for direct consumption or processing; and germplasm M484 yielded high cyanide and carbohydrate content making it more suitable for starch processing.

Abstract

Cassava (Manihot esculenta Crantz) is one of the most important food crops grown in the tropical regions of the world. Even though cassava is also cultivated and consumed in southern China there is little knowledge of the composition of the cassava grown here. Therefore 16 cassava germplasms collected from Hainan Province in China were used in the present work to determine the proximate composition amino acid mineral and hydrogen cyanide contents of their roots. The results showed significant differences among the cassava germplasms. The cassava germplasms contained 85.56 - 90.50 g/100 g carbohydrate 0.03 - 1.28 g/100 g crude lipid 1.41 - 4.74 g/100 g crude protein 2.90 - 8.60 g/100 g moisture and 2.89 - 4.38 g/100 g ash. The mineral contents were 62.89 - 467.36 425.01 - 1474.71 and 070 - 7.95 mg/kg for Ca Mg and Pb respectively; and 1523.08 - 4749.46 75.57 - 766.33 9.57 - 282.83 4.48 - 26.69 0.75 - 373.60 and 10.43 - 29.04 mg/kg for K Na Zn Mn Cu and Fe respectively. The HCN content ranged from 0.32 - 1.53 mg/g. Among the 16 cassava germplasms ZMH1071 ZMJ615 and SC12 yielded higher carbohydrate content and lower HCN content making them suitable for direct consumption or processing; and germplasm M484 yielded high cyanide and carbohydrate content making it more suitable for starch processing.
