To understand the variation in carotenoid and folate profiles of field pea, chickpea, and dry bean.


Four studies were completed to evaluate the carotenoid and folate profiles of pea and chickpea. Green cotyledon pea cultivars had approximately two times more total carotenoids than yellow cotyledon pea cultivars. Desi chickpea cultivars had greater concentration of total carotenoids than kabuli cultivars. In a study of seed fractions, carotenoid concentration was greatest in the cotyledon followed by embryo axis and seed coat in both pea and chickpea cultivars. Cotyledons had a greater concentration of individual and total carotenoids than other tissues in pea and chickpea. Folate components were identified using mass spectrometry.
