This study aims to explore diversity in rheological properties, structure and digestibility of starches isolated from 16 common bean ( Phaseolus vulgaris L.) varieties from Europe and Asia. All common bean starches showed C A -type (closer to A-type) crystallinities. Relative crystallinity varied from 27.8% to 32.9% with a similar coefficient of variation (CV: 5.0%–6.0%) to 1045/1014 cm −1 ratio (varied from 0.429 to 0.508). A peak position shift occurred at 989 and 1014 cm −1 . The peak intensity at 989, 1014 and 1045 cm −1 varied greatly and the variation followed the order: at 989 > 1014 > 1045 cm −1 . A great variation was also observed for the presence of hydroxyl group and the C–O bond stretching. Rapidly digestible starch, slowly digestible starch and resistant starch contents varied from 61.5% to 73.0% (CV: 4.7%), 0.3% to 7.2% (CV: 53.7%) and 23.9% to 35.4% (CV: 11.4%), respectively. CV of storage modulus (G′) and loss tangent (tan δ) were 29.4%–39.4% and 11.9%–36.1%, respectively. G′ max (maximum G′ during heating) varied from 2.52 to 10.32 kPa. These starches showed high G′. This study indicates extensive variation in starch properties among these common bean varieties, which may be useful for selecting varieties for processing, or selecting genotypes for plant breeding.

Twenty-nine legumes were assessed for their nutritional and phytochemical compositions. Soybean and black soybean had the highest protein contents (34.05–42.65 g/100 g DW, dry weight of legumes), particularly being a rich source of lysine (1.78–2.23 g/100 g DW. Soybean and black soybean had the highest fat contents (14.13–22.19 g/100 g DW). Broad beans had the highest unsaturated fatty acids (83.57–89.01 g/100 g fatty acid), particularly rich in α-linolenic and linoleic acid. The highest and the lowest dietary fiber were found in red kidney beans (35.36 g/100 g DW) and mung beans (22.77 g/100 g DW), respectively. Except for soybean and white kidney bean, 6 major anthocyanins in the legumes samples were identified. The soybean contained the highest total tocopherols content (90.40–120.96 μg/g dry weight of beans), followed by black soybean (66.13–100.76 μg/g DW). The highest carotenoids were found in lentils (4.53–21.34 μg/g DW) and red kidney beans (8.29–20.95 μg/g DW).

BACKGROUND As probiotics, soy oligosaccharides have become popular as healthy foods to reduce disease risk. However, comprehensive information about oligosaccharides in different food legumes is limited. RESULTS In this study, eight oligosaccharides were well detected and quantified in different varieties of eight legume species using high-resolution mass spectrometry. It was determined that species could be distinguished by total content of oligosaccharides and their distribution modes. Among the studied species, Vigna unguiculata is a better resource of non-digestible oligosaccharides, while Vicia faba and black soybean ( Glycine max ) are at a disadvantage. Normally, stachyose predominates in non-digestible oligosaccharides, except in mung bean and broad bean, where verbascose predominates. For mung bean and green soybean, the seed coat should be taken into account for oligosaccharide consumption. The developed high-resolution mass spectrometry method greatly simplified the sample preparation process and permitted the identification of oligosaccharides without reference compounds. CONCLUSION This work involved extensive sample collecting and provided useful information for consumers. The developed method may be useful for rapid quantification of oligosaccharides in related foods. © 2014 Society of Chemical Industry

The effects of heat moisture treatment (HMT) times on the physicochemical properties of three bean flours and their starch were analyzed. The colors of L *, b * and ΔE values increased significantly with time. The adzuki bean and pea flours showed better WAI and SP, and better gelation of starch at 2 h. The rheological properties of mixed HMT dough (3:7) exhibited the typical solid-like weak gel behavior. HMT had a significantly decreased on the pasting viscosity of bean flour starch with treated time. HMT caused the starch granules damage, but did not radically change the crystal type. FTIR results showed more proteins attached to the surface of starch granules, and the short-range molecular order decreased the DO at 2 h. In vitro digestibility inferred that RDS converted into SDS and RS . These results indicated that HMT significantly affected the digestibility and physicochemical properties of bean flours.

Although the impact of postharvest trans-2-hexenal (E2H) application in maintaining the quality of horticultural products has been widely studied, its effect on fresh common beans and the preservation mechanism remain unexplored. In this study, the impacts of E2H on reactive oxygen species (ROS) and cell wall metabolisms, and lignin biosynthesis in common beans were investigated. Fresh common beans fumigated with E2H (0, 0.5, 1.0, 1.5, and 2.0 μL L −1 ) were stored at 20 ± 1 °C for 12 days. Results showed that 1.0 μL L −1 E2H remarkedly repressed the decline of chlorophyll content to delay the yellowing, maintained ROS homeostasis, modulated cell wall metabolism-related enzyme activities to regulate cell wall components, and inhibited lignin biosynthesis-related enzyme activities to reduce lignin accumulation, thereby alleviating softening and lignification in common beans. These findings indicated that E2H could improve antioxidant activity, delay softening, and attenuate lignification to mitigate the quality deterioration in common beans.

The effect of legume proteins (soy protein (SP), chickpea protein (CP) and peanut protein (PP)) on the properties of wheat starch-lauric acid (WS-LA) system and its intrinsic mechanism were investigated. RVA, digestion experiment and TGA results showed that legume proteins prompted the viscosity peak formation during cooling stage and increased anti-digestion and thermal stability of WS-LA system. FT-IR, Raman, XRD and 13 C NMR results indicated that legume proteins improved the long-range and short-range ordering degree and single-helix structure of WS-LA system. SP had greater influence on the properties of WS-LA system than that of CP and PP. Proteins with high solubility, emulsifying properties and β-sheet content were conducive to starch-based complexes formation. Molecular dynamics simulation results indicated that major forces for WS-LA-SP formation were hydrogen bonding and van der Waals forces. This study offered crucial information on starch-fatty acid-protein complexes formation for proteins selection in starch-based products development.

In this work, we synthesized a series of magnetic deep eutectic solvents (MDESs) with lanthanide metal chlorides as paramagnetic metal centers and developed a reversed-phase dispersive liquid–liquid microextraction method (DLLME) based on the in-situ dispersion of MDESs for the extraction and preconcentration of triazole fungicides (TFs) from bean samples. Different MDESs were synthesized by combining quaternary ammonium salts, short-chain carboxylic acids, and lanthanide metal chlorides. The dissolution of short-chain carboxylic acids in n-hexane led to the in-situ dispersion of MDESs to replace the toxic dispersant of traditional DLLME species and shorten extraction time. Cobalt powder was added to encapsulate MDESs to enhance the magnetic properties after the extraction and achieve the purpose of easy phase separation. Notably, the highest extraction efficiency of TFs was observed in the MDES formed by tetrabutylammonium bromide, propionic acid, and gadolinium chloride in a ratio of 1:10:0.06. We optimized various parameters that affected the extraction efficiency of the method, including volume of MDES, extraction time, amount of cobalt powder, and volume of elution solvent. Under the optimal conditions, the detection limits (LODs) and quantification limits (LOQs) of the technique varied between 0.097–0.13 ng·g −1 and 0.32–0.43 ng·g −1 , respectively. To assess the accuracy, the method was tested with samples spiking at three concentration levels, and the obtained results revealed that the recovery rates varied from 88.97–113.7%. To summarize, this study represents the initial application of in-situ dispersed lanthanide metal chloride anion-MDESs for analyzing bean samples and the proposed DLLME technique is rapid, straightforward, and efficient.

In this study, Fe/N/Cs oxygen reduction reaction (ORR) catalysts with high specific surface area, catalytic activity were synthesized using legume biomass with different protein content. The catalytic activity of the Fe/N/C catalysts was confirmed to be related to the protein content of the biomass precursor by characterization and electrochemical tests. The catalysts (named as Fe/N/C-T) from lactone tofu have the highest N/C ratio related to ORR, and the air-cathode loaded with Fe/N/C-T catalysts exhibited the best ORR performance in linear sweep voltammetry (LSV) tests, which was comparable to that of commercial Pt/C catalysts. MFCs with AC(Fe/N/C-T) air-cathode produced a maximum power density of 0.486 mW cm −2 , higher than Pt/C (0.437 mW cm −2 ) with the same loading. In addition, the Fe/N/C-T catalyst demonstrated high stability and resistance to toxicity in long-term operation, which can be an alternative to commercial Pt/C.
