Abstract:

In order to study the fresh tuber processing suitability of different cassava cultivars, 12 edible cultivars were processed into steamed cassava, cassava juice and cassava soup for quality characteristics identification and sensory evaluation. The suitability of cultivars were comprehensively evaluated by associatied analysis and principal component analysis, and the main impact factors were analyzed. Five components were extracted from 15 quality evaluation traits of steamed cassava. Of them, chroma a*, chroma b*, fiber sensation, evaluation, springiness, hardness and gumminess played the key role in fresh tuber processing. Three components were extracted from 10 quality evaluation traits of cassava juice, and the color, texture, pH value and viscosity played the key role in fresh tuber processing. Two components were extracted from five sensory evaluation traits of cassava soup, and evaluation, smoothness played the key role in fresh tuber processing. In addition, the main quality evaluation indexes of steamed cassava were affected by the content of starch, dry matter, crude fiber and protein in fresh tuber. The main quality evaluation indexes of cassava juice were affected by the content of protein, soluble sugar and amylose in fresh tuber. Among the twelve cultivars, P3 was suitable for fresh consumption, M33, M9, ST and NK-10 were suitable for steaming cassava. ST, P9, M11 and P3 were suitable for processing cassava juice. M9, M11, ST and NK-10 were suitable for processing cassava soup.
