Biofortification potential in common bean (Phaseolus vulgaris L.): bioactive compounds, antioxidant capacity and physicochemical properties of 155 varieties grown in México

Abstract

Common bean has been classified as an almost perfect food due to its high content of fiber, protein and bioactive compounds and its high antioxidant capacity, which has been attributed to having prevent diabetes, oxidative stress, bowel inflammation and cardiovascular diseases. The objective of this research work was to characterize the physicochemical properties and bioactive compounds of 155 varieties of common bean (Phaseolus vulgaris L.) produced in Mexico with potential to be biofortified. The contents of protein, fiber, fat, carbohydrates and energy were analyzed by the methods established by the AOAC, in addition the antioxidant capacity (DPPH), the content of total phenols, flavonoids, anthocyanins and phytic acid were obtained. Cluster, correlation, and principal component analysis were conducted. A total of 14 outstanding varieties was identified, where four varieties stood out about phenol and flavonoid content. A second group comprised by 10 varieties had high protein and anthocyanin levels and showed the second highest content of phenols and flavonoids. The diversity of beans obtained in outstanding varieties provides options for biofortification programs based on the consumption or place of origin of each variety.
