| Sumario: | This study aimed to characterize the nutritional and nutraceutical properties of ten Mediterranean bean landraces
compared to a commercial variety (Big Borlotto, Batlle Seeds). Significant genetic diversity was found
among the landraces, affecting their nutritional composition, mineral content, and bioactive compounds.
Essential minerals such as calcium, iron, and zinc exhibited considerable variability, with landraces 103, 15, 40,
and 102 showing higher mineral levels than the control variety. The fatty acid profiles varied, with linolenic acid
being predominant, accounting for 39.1–47.3 % of total fat, depending on the genotype. Positive correlations
between fatty acids and mineral content suggest complex interdependencies influencing grain quality, with the
strongest correlations observed between Mg and linolenic (r = 0.66) or palmitic (r = 0.63) acids. Beans with
colored seed coats exhibited higher antioxidant capacity attributed to phenolic acids, flavonoids, carotenoids,
and ascorbic acid, emphasizing seed coat color as an indicator of nutritional quality. Principal Component
Analysis (PCA) identified five clusters based on physical and nutritional traits, revealing correlations between
seed size, color, and quality. These findings highlight the potential of bean landraces to promote local economies
and biodiversity. |
