The common dry bean (Phaseolus vulgaris L.) is a globally produced pulse crop and an important source of micronutrients for millions of people across Latin America and Africa. Many of the preferred black and red seed types in these regions have seed coat polyphenols that inhibit the absorption of iron. Yellow beans are distinct from other market classes because they accumulate the antioxidant kaempferol 3-glucoside in their seed coats. Due to their fast cooking tendencies, yellow beans are often marketed at premium prices in the same geographical regions where dietary iron deficiency is a major health concern. Hence, this study compared the iron bioavailability of three faster cooking yellow beans with contrasting seed coat colors from Africa (Manteca, Amarillo, and Njano) to slower cooking white and red kidney commercial varieties. Iron status and iron bioavailability was assessed by the capacity of a bean based diet to generate and maintain total body hemoglobin iron (Hb-Fe) during a 6 week in vivo (Gallus gallus) feeding trial. Over the course of the experiment, animals fed yellow bean diets had significantly (p ≤ 0.05) higher Hb-Fe than animals fed the white or red kidney bean diet. This study shows that the Manteca yellow bean possess a rare combination of biochemical traits that result in faster cooking times and improved iron bioavailability. The Manteca yellow bean is worthy of germplasm enhancement to address iron deficiency in regions where beans are consumed as a dietary staple.

Abstract Objectives The common dry bean (Phaseolus vulgaris L.) is a globally produced pulse crop and an important source of protein and micronutrients for millions of people across Latin America and Africa. In these regions, energy for cooking is expensive or scarce and long cooking times deter consumers from purchasing beans. In addition, many of the preferred black and red seed types have phytate and polyphenols that limit the absorption of trace minerals. Yellow beans are unique because their seed coats are rich in kaempferol 3-glucoside, a recently discovered promoter of iron absorption. Several market classes of yellow beans are sold throughout Latin America and Africa, where they are marketed at premium prices for their fast cooking tendencies. Exploring the yellow bean's unique heritage to develop new fast cooking varieties that deliver more absorbable iron would be useful for regions where inhabitants have limited access to fuelwood for cooking. This study compared the iron bioavailability of three fast cooking yellow beans from Africa with contrasting seed coat colors (Manteca, Amarillo, Njano) to slower cooking white and red kidney commercial varieties from North America (Table 1). Methods Cooked beans were formulated into diets with the complementary food crops of potato, rice and cabbage. Iron bioavailability was measured as ferritin formation in an in vitro digestion Caco-2 bioassay and the ability to maintain total body iron hemoglobin (Hb-Fe) during a 6 week in vivo (Gallus gallus) feeding trial. Results Animals fed yellow bean diets had faster growth rates, accumulated more dietary iron and had higher Hb-Fe than animals fed either kidney bean diet (Figure 1). In contrast to yellow beans, the kidney beans had almost no kaempferol 3-glucoside (Table 2). When compared to the other four bean based diets, the fast cooking Manteca yellow bean diet had the highest Caco-2 ferritin formation in vitro (Table 3) and delivered the largest increase in Hb-Fe in vivo (Figure 1). Conclusions Through the added benefit of fast preparation times and improved iron quality after cooking, this study provides evidence that the Manteca market class is worthy of germplasm enhancement as a new convenience food to help alleviate trace mineral deficiencies in regions where beans are widely accepted as a dietary staple.

Iron-biofortification of crops is a strategy that alleviates iron deficiency. The common bean (Phaseolus vulgaris L.) is an attractive candidate for biofortification. However, beans are high in polyphenols that may inhibit iron absorption. In vitro studies have shown that iron bioavailability from white beans is higher than that from colored beans. In this study, our objective was to determine if white beans contain more bioavailable iron than red beans and to determine if the in vitro observations of bean-iron bioavailability would be evident in an in vivo feeding trial. We compared iron bioavailability between diets containing either white (Matterhorn) or red (Merlot) beans, which differ in polyphenol content. One-week-old chicks (Gallus gallus) were divided into four groups: 1. “WB”: 40 % white-bean diet; 2. “RB” :40 % red-bean diet; 3. “WB + Fe”: 40 % white-bean diet; 4. “RB + Fe”: 40 % red-bean diet (51, 47, 179, and 175 ppm iron, respectively). Diets 1 and 2 had no supplemental iron; whereas 125 µg/g iron was added to diets 3 and 4. For 8 weeks, hemoglobin, feed consumption, and body weights were measured. Divalent metal transporter 1 (iron-uptake-transporter), duodenal-cytochrome-B (iron reductase), and ferroportin (iron-exporter) expressions were higher (p < 0.05), villus-surface-area (tissue iron-deficiency adaptation) was greater in the “RB” group vs. other groups. Cecal microflora was similar between treatments. Hemoglobin, body-hemoglobin iron, and body weights were lower in the “RB” group vs. other groups (p < 0.05). In vitro analysis showed lower ferritin formation (less bioavailable iron) in cells exposed to the “RB” diet. We conclude that the in vivo results support the in vitro observations; i. e., white beans contain more bioavailable iron than red beans.

EM (effective microorganisms) is a biofertilizer consisting of a mixed culture of potentially beneficial microorganisms. In this study, we investigated the effects of EM treatment on leaf in vivo chlorophyll a fluorescence of photosystem II (PSII), yield, and macronutrient content of bean plants grown on different substrates (nutrient rich substrate vs. nutrient poor sandy soil) in controlled environmental conditions (pot experiment in greenhouse). EM-treated plants maintained optimum leaf photosynthetic efficiency two weeks longer than the control plants, and increased yield independent of substrate. The levels of seed nutritionally-relevant molecules (proteins, lipids, and starch) were only slightly modified, apart from the protein content, which increased in plants grown in sandy soil. Although EM can be considered a promising and environmentally friendly technology for sustainable agriculture, more studies are needed to elucidate the mechanism(s) of action of EM, as well as its efficacy under open field conditions.

Cooking Times

Carioca is the most important edible dry bean (Phaseolus vulgaris L.) grown in Brazil. It represents the largest dry bean market class in the world. The seed coat of carioca beans will darken under adverse harvest conditions and with the increasing of storage time. In general, darkened seeds are associated with older seeds that suffer from prolonged cooking times. A relatively new ‘slow darkening’ trait is available in carioca that delays seed coat darkening under storage. However, its effect on cooking time is unknown. The objective of this work was to evaluate two induction methods of seed coat darkening and to examine the effect of slow darkening trait on cooking time after storage. Lines derived from four segregating populations resulting from crossings between cultivar BRSMG Madrepérola with slow seed coat darkening, and the parents BRS Estilo, BRS Cometa, BRS Notável and BRS Sublime with normal darkening were evaluated. An experiment inlcuding 220 lines, 55 per population and the five parents, in a 15x15 triple lattice was conducted in the winter growing season in Brasilia. Seed coat darkening and cooking time traits were evaluated. Two methods for inducing seed coat darkening were compared: an accelerated aging test using UV light for 72 hours, and an extended storage for 90 days under ambient conditions. The correlation between the induction methods ranged from 0.77 to 0.85 for the different populations indicating either method could be used to discriminate lines with normal versus slow darkening trait. The percentage of light-colored grain lines was identified by both induction methods of seed coat darkening ranged from 75 to 85.7% in the populations. The genetic correlation between seed coat darkening and cooking time varied from -0.06 to -0.48, indicating that in some populations there is no significant genetic correlation between seed coat darkening and cooking time. Thus, light colored grains are not indicative of low cooking time, when they are considered genotypes with genetic variation for the seed coat darkening.

Abstract Objectives The aim of this research was to evaluate the anti-inflammatory properties of an oven-baked nixtamalized corn (Zea mays L.)/cooked common bean (Phaseolus vulgaris L.) chip in a model of chronic colitis in vivo. The hypothesis was that the chip consumption would prevent colon barrier disruption and improve enzymatic biomarkers by the modulation of infiltration and adhesion of inflammatory cells. Methods A 70% corn and 30% bean chip (7030C) was evaluated, using dextran sodium sulfate (DSS, 2% v/v) as chemical inductor of colitis. After 1-week of acclimatization, 36 CD-1 male mice (6–8 weeks age) were randomly divided into 5 groups: G1 (negative control, fed with basal diet, BD, and water); G2 (positive control, BD + DSS), G3 (100 g 7030C/kg body weight, BW/day + BD), G4 (200 g 7030C/kg BW + BD) and G5 (300 g 7030C/kg BW + BS). The G2-G5 groups were administered DSS every other week, during 5-weeks.After the mice were euthanized, BW and disease activity index (DAI) were recorded. Liver, colon, and spleen were collected, weighed and analyzed for histology. Colonic myeloperoxidase (MPO)/fecal b-glucuronidase (GLUC) activities were also quantified, as well as fecal/cecal metabolites. The colonic mRNA expression of inflammation-associated genes was conducted using a gene inflammation profiler array. Results DSS increased DAI up to 2 units, BW loss was 10–17%, and induced colon shortening 10–15%. Compared to G2, G4 exhibited significantly (p < 0.05) lower DAI (0.75 ± 0.01), spleen relative weight (0.003 ± 0.0001) and colon weight/length ratio (0.045 ± 0.008). The histological analysis showed that the chip consumption prevented colonic barrier damage. G4 displayed the lowest MPO and GLUC among all DSS-induced groups (0.004 ± 0.0004 mU/mg colon; 0.44 ± 0.01 mmol/min/g feces, respectively), and the lowest seric content of MCP-1 protein. Amid all the quantified metabolites, the chip consumption significantly reduced the fecal/cecal content of acetic acid, while butyric and propionic increased at the end of the study. Inflammation gene expression was modulated by the chip consumption. Conclusions Our results suggest that the consumption of this chip might alleviate chronic colitis symptoms because of a protective effect in the gut barrier function and the modulation of infiltration of inflammatory cells.
