Chemistry Composition and Bioaccessibility Study of Phenolic Compounds and Carotenoids of New Brazilian Biofortified Sweet Potato “CIP BRS Nuti”

Le résumé fourni par la source

ABSTRACT Sweet potatoes biofortified in carotenoids have been an alternative to combat malnutrition in vulnerable populations. This work is the first comprehensive study of the bioactive potential of the new Brazilian biofortified sweet potato cultivar “CIP BRS Nuti.” In two harvests, the chemical composition and profiles of organic acids, phenolic compounds, and carotenoids were analyzed using high‐performance liquid chromatography. The bioaccessibility of phenolics and carotenes was also studied. The main simple sugars and organic acids found were glucose, fructose, citric, malic, succinic, and lactic acids. “CIP BRS Nuti” showed high concentrations of chlorogenic acid (228.3–330.4 mg/kg) and hesperidin (385.2–530.9 mg/kg), with the presence of other phenolics such as catechin, epicatechin, and procyanidin B1, with high levels of bioaccessibility (> 104%). The main carotenoid quantified was 9‐ cis ‐β‐carotene (294.9–503.8 mg/kg), with low bioaccessibility, but β‐carotene and lycopene were also present. Our results show the nutritional and bioactive potential of the “CIP BRS Nuti” potato, providing essential information for its use in food and industrialization, with an applied view to nutrition and food science.
