Characterization of Bioactive Compounds, Mineral Content and Antioxidant Capacity in Bean Varieties Grown in Semi-Arid Conditions in Zacatecas, Mexico

Abstract

This research describes the characterization of bioactive compounds, mineral content, and antioxidant capacity in bean varieties grown in semi-arid conditions in Zacatecas, Mexico. This will provide better progress perspectives for agriculture nationwide and will ensure that bean crops are in the condition to satisfy the population’s nutritional needs by placing it not only as one of the foodstuffs comprising Mexico’s basic diet but also as one of the legumes having greater biofortification potential in Mexico. Eleven bean varieties were collected (flor de mayo, bayo, frijola, patola, navy beans, flor de junio, reata beans, Japanese beans, black beans, canary beans, and pinto Saltillo). The evaluation done included the physical and physico-chemical characteristics, as well as the mineral content, bioactive compounds and antioxidant capacity of these bean varieties. Data gathered were subject to a variance and mean separation analysis. The most remarkable individual results were as follows: Canary beans had the highest iron content (105.29 mg/kg), while bayo beans had the highest zinc concentration (48.18 mg/kg) and reata beans had the highest level of protein (26.88%). The varieties showing the most remarkable results with regard to zinc, iron and protein content and antioxidant capacity were as follows: Flor de junio, flor de mayo, reata beans, navy beans and pinto Saltillo; however, the most remarkable variety in comprehensive terms was flor de junio, which showed a reducing power of 0.20%, an antioxidant capacity of 80.62% inhibition, a protein content of 0.17%, in addition to Ca (0.24%), Fe (90.97 mg/kg), Zn (27.23 mg/kg), fiber (3.22%), energy (353.50 kcal), phenols (94.82 mg gallic acid (GA)/g extract) and flavonoids (1.30 mg mg Cat/g−1 dw). Finally, we came to the conclusion that beans grown in Zacatecas, Mexico, offer a huge benefit to consumers as a result of the mineral, protein, fiber, bioactive compounds, and antioxidant capacity contributions such beans provide. Thus, these beans can be used in a biofortification program using micronutrients to improve their nutritional quality.

Agronomic Performance, Capsaicinoids, Polyphenols and Antioxidant Capacity in Genotypes of Habanero Pepper Grown in the Southeast of Coahuila, Mexico

“…It should be noted that within the CIELCH color model, the lower values associated with C * indicate a lower color purity, while higher values (close to 50) represent a purer color. Therefore, the lower the saturation of a given color, the greater the grayish hue and discoloration [47]. These results were similar to those reported by Vera-Guzmán et al [44], who reported L * values in a range from 21.8 to 52.8 in wild genotypes of Capsicum annuum L cultivated in Oaxaca, Mexico.…”

Therefore, the lower the saturation of a given color, the greater the grayish hue and discoloration [47]. The hue angle (h *) readings were found in the range from 32.04 to 51.91 (Table 3), according to these values, the color of the analyzed samples is red-yellow, a tone that is associated with a h * value of 90° on the hue circle.…”

Biofortification efficiency with magnesium salts on the increase of bioactive compounds and antioxidant capacity in snap beans

“…This dose was better than the 200 ppm dose where 55% scavenging activity was obtained. Similar percentages were reported by SANCHEZ et al (2017) and HERRERA-HERNÁNDEZ et al (2018) who found values ranged from 45-80% scavenging activity in biofortification studies in beans.…”

Phenolic Compounds, Antioxidant Activity and Mineral Contents in Grains of Phaseolus lunatus L. and P. coccineus L. Landraces

“…Zn and Fe are essential mineral elements for human health and were exceptionally high in the PL-005 and PL-014 populations of P. lunatus, the PC-022 population of P. coccineus and the PV-003 population of the control species P. vulgaris, with 3.88 to 4.49 and 5.62 to 7.38 mg 100 g -1 Zn and Fe, respectively (Table 5). These values are lower than the Fe content reported by Seidu et al (2015) and Palupi et al (2022) in P. lunatus but within the ranges of Fe and Zn in P. vulgaris reported by Herrera-Hernández et al (2018).…”
