In vitro digestive stability and uptake by Caco-2 human intestinal cells of nonfluorescent chlorophyll catabolites

► Two nonfluorescent chlorophyll catabolites (NCCs) have been described in pepper fruits for the first time. ► It has been shown for the first time that NCCs are resistant to the digestion process. ► It has been shown for the first time that NCCs can be absorbed by human intestinal cells.
