AbstractObjectiveCyanide is a highly toxic compound, and the consumption of products containing cyanide is of singificant public health concern. In contrast, β-carotene possesses essential nutritional attributes related to human health, therefore the characterisation and quanfication of both compounds in food products is both fundamental and necessary. This investigation sought to identify the cyanide and β-carotene levels in two flours produced from the roots of two varieties of cassava (Manihot esculenta crantz), namely UMUCASS-38 (TMS 01/1371) and NR 8082, and their associated food products.ResultsThe fresh tuber, raw flour and food products were analysed for levels of residual cyanide and β-carotene using standard analytical methods. The cyanide content of NR 8082 (18.01±0.01 ppm) and UMUCASS 38 (17.02±0.02 ppm) flours were significantly higher (p < 0.05) than the residual cyanide levels determined in the cookies (10.00±0.00 ppm) and cake (7.10±0.14 ppm). The levels of β-carotene determined in the sample varied significantly (p < 0.05). The highest levels of β-carotene (6.53±0.02 µg/g) were determined in raw roots of UMUCASS 38 while NR 8082 levels of β-carotene were 1.12±0.02 µg/g. Processing the roots into flour reduced the β-carotene content to 4.78±0.01 µg/g and 0.76±0.02 µg/g in UMUCASS 38 and NR8082 flours, respectively. Cookies and cake produced from flour derived from the UMUCASS 38 variety had 2.15±0.01 µg/g and 2.84±0.04 µg/g of β-carotene, respectively.

Summary 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 β-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- β-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.
