In this study, the metabolomics characterization focusing on the carotenoid composition
of ten cassava (Manihot esculenta) genotypes cultivated in southern Brazil by UV-visible
scanning spectrophotometry and reverse phase-high performance liquid chromatography
was performed. Cassava roots rich in -carotene are an important staple food for populations
with risk of vitamin A deficiency. Cassava genotypes with high pro-vitamin A activity
have been identified as a strategy to reduce the prevalence of deficiency of this vitamin.
The data set was used for the construction of a descriptive model by chemometric analysis.
The genotypes of yellow-fleshed roots were clustered by the higher concentrations of cis-
-carotene and lutein. Inversely, cream-fleshed roots genotypes were grouped precisely
due to their lower concentrations of these pigments, as samples rich in lycopene (redfleshed)
differed among the studied genotypes. The analytical approach (UV-Vis, HPLC,
and chemometrics) used showed to be efficient for understanding the chemodiversity of
cassava genotypes, allowing to classify them according to important features for human
health and nutrition. |
