Primary Study of the Nutrient Contents in the Flesh and Cortex of Cassava Root
Aiming to improve the utilization value of cassava root, 7 nutrient contents in the flesh and cortex of 3cassava clones were analyzed. The results indicated that dry matter content(DMC) of fresh flesh was 31.5%-42.1%,starch content(SC)of dry flesh was 76.4%-87.0%, which were very significantly higher than that in cortex. The contents of β-carotene and Vitamin C in fresh cortex were 0.28-0.63 mg/hg and 11.9-26.1 mg/hg, respectively, the contents of crude protein, soluble sugar and crude fiber in dry cortex were 25.0%-28.2%, 10.5%-21.5% and14.0%-19.9%, respectively, Above 5 nutrient contents in fresh or dry cortex were very significantly higher than that in flesh. Compared with the related research, the flesh nutrition is better than or can match with the sweet potato and potato, the cortex nutrition is better than or can match with the both bran of rice and wheat. Moreover, there are coexistence of higher DMC, higher SC and low crude fiber content together in the flesh and cortex.
