Abstract
This study quantified fatty acids and evaluated the proximate composition, antioxidant activity paired with Quencher procedure and total phenolic compounds in Brazilian bean cultivars. The samples showed high amounts of polyunsaturated fatty acids, such as linoleic acid (191.54 to 329.50 mg g-1 of total lipids) and α-linolenic acid (228.03 to 367.27 mg g-1 of total lipids). The obtained ratios between Omega 6 and 3 fatty acids were low, between 0.71 and 1.12. In relation to antioxidant activity assays, the cultivars showed the best results upon employing the 2,2-azinobis (3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS) method (2401.34 to 4394.80 µmol Trolox equivalent g-1). The lowest results were observed in the ferric reducing antioxidant power (FRAP) assays, 530.93 to 1440.13 µmol Trolox equivalent g-1. The results from 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ABTS methods showed the greatest correlation between themselves (r = 0.619). High concentrations of total phenolic compounds were also detected in the studied cultivars, which varied from 81.85 to 173.65 mg gallic acid equivalent 100g-1.
Highlights
IntroductionThe common bean (Phaseolus vulgaris L.) is the most important pulse (annual leguminous food crops, such as chickpea, cowpea, lentils, pea and others that are harvested for dry seeds) in the world, among the approximately twenty species of legumes most consumed by humans.[1,2]
The common bean (Phaseolus vulgaris L.) is the most important pulse in the world, among the approximately twenty species of legumes most consumed by humans.[1,2]
Their values are slightly superior to the 19.5% found by Vargas‐Torres et al.[27] and similar to the 22% determined by Shimelis and Rakshit.[28]
Summary
The common bean (Phaseolus vulgaris L.) is the most important pulse (annual leguminous food crops, such as chickpea, cowpea, lentils, pea and others that are harvested for dry seeds) in the world, among the approximately twenty species of legumes most consumed by humans.[1,2]. It is an important source of protein, minerals, and vitamins for millions of people in developing and developed nations and is a staple food of the South American, and Eastern and Southern African populations.[3] Among these countries, Brazil is the second largest world producer of beans, with approximately 3.1 millions of tons produced, but is one of most important consumers (16.30 kg per capita year−1).[4].
