Conteúdo:

Manihot esculenta roots rich in &#946;-carotene are an important staple food
for populations with risk of vitamin A deficiency. Cassava genotypes with high provitamin
A activity have been identified as a strategy to reduce the prevalence of
deficiency of this vitamin, In this study, the metabolomics characterization focusing
on the carotenoid composition of ten cassava genotypes cultivated in southern
Brazil by UV-visible scanning spectrophotometry and reverse phase-high performance
liquid chromatography was performed. The data set was used for the construction
of a descriptive model by chemometric analysis. The genotypes of yellow
roots were clustered by the higher concentrations of cis-&#946;-carotene and lutein.
Inversely, cream roots genotypes were grouped precisely due to their lower concentrations
of these pigments, as samples rich in lycopene 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.
