Ferulic acid is a prominent bioactive compound found in wheat grains, known for its beneficial health effects, prompting significant interest from breeders and producers. The aim of this study was to identify new quantitative trait loci (QTL) to aid in the development of wheat varieties with increased ferulic acid concentration (FAC).
In this study, a recombinant inbred line population, resulting from a cross between Zhongmai 578 and Jimai 22, was evaluated in five different environments. Genotyping was performed using the wheat 50 K single-nucleotide polymorphism (SNP) array. Three stable QTL, named QFAC.caas-2D, QFAC.caas-3B, and QFAC.caas-4D, were identified. These QTL explained 4.24%–7.09%, 3.7%–4.57%, and 3.20%–5.06% of the phenotypic variances, respectively. Furthermore, three SNPs closely associated with above QTL were successfully converted into kompetitive allele-specific polymerase chain reaction (KASP) markers.
FAC is a complex trait governed by multiple minor-effect QTL. The successful development of KASP markers opens up avenues for marker-assisted selection in breeding programs.
This study establishes a genetic foundation for understanding the genetic basis of FAC in wheat. The identified QTL and developed KASP markers offer valuable insights for quality breeding initiatives and the production of functional wheat-based foods.
Faba beans are emerging as highly nutritious ingredients that have the potential to contribute to the global demand for healthy and sustainable plant-based proteins. The current review aims to provide a summarized overview of faba bean macronutrients, protein quality, and antinutritional factors (ANFs), as well as their reduction strategies through a variety of processing means.
Relative to other pulses, faba beans are higher in protein content and similar in protein quality. However, without proper preparation and/or processing, the presence of minor amounts of ANFs can hinder their nutritional value. These nonnutritive, but biologically active, compounds can be diminished through mechanical, thermal, and nonthermal treatments.
Nonconventional processing techniques to retain or improve protein quality remain an area of future research for improving faba bean nutrition and expanding its utilization.
This review will advance the science and utilization of faba bean ingredients while providing future research opportunities.
Chlamydomonas reinhardtii (C. reinhardtii) is recognized as a sustainable source of high-quality protein. This study aimed to assess the potential application of C. reinhardtii for producing microalgae-fortified steamed bread. To reduce the inherent green color and volatile compounds of the microalgae, lactic acid bacteria (LAB) fermentation was applied as a pretreatment method for C. reinhardtii. Subsequently, both unfermented (unFC) and fermented C. reinhardtii (FC) were added to steamed bread formulations (4%, 8%, 12%, and 16% wheat flour substitution).
The results showed that the incorporation of unFC into steamed bread had a dose-dependent negative impact on the dough fermentation performance and the quality of steamed bread, including volume, texture, and sensory attributes, rendering the steamed bread unacceptable. Fermentation altered the amino acid profile of C. reinhardtii, caused the color to shift from green to red (a*, −14.7 vs. 7.0), and reduced unpleasant volatile components. Further, fermentation reduced the negative impact of microalgae incorporation, especially at substitution levels of 4% and 8%, which manifested as an increased dough fermentation volume and improved bread volume with reduced crumb firmness of the steamed bread. However, in sensory analysis, the steamed bread that contained 4% FC had an overall acceptability similar to the control sample.
Microalgae-enriched steamed bread could be produced by incorporating up to 4% FC to improve its nutritional profiles while maintaining overall sensory acceptability by the consumers.
LAB fermentation of C. reinhardtii is a feasible strategy to address the sensory and structural challenges that hinder the incorporation of algae into food products.
This study investigated the physicochemical properties, particle size, pasting properties, phenolic acids, carotenoid content, and fresh noodle quality characteristics of whole einkorn flour (WEF) in comparison with whole wheat flour (WWF). Three WEF samples from different cultivation regions in Turkey were analyzed.
The WEFs exhibited significant variations in all quality characteristics compared to WWF, influenced by different einkorn growing environments. Phenolic acid and carotenoid contents, along with antioxidant activity, were highest in WEF1 and WEF2, highlighting their potential nutritional benefits. Noodles made from WEF3 demonstrated quality equivalent to that of WWF, although their protein content and nutritional value were relatively lower than those of WEF1 and WEF2.
This research demonstrates the potential of WEF for fresh noodle production with quality comparable to WWF. The nutritional value varies by cultivation area, emphasizing the importance of selecting appropriate cultivars and growing conditions for optimal results.
This study highlights, for the first time, the nutritional value and quality characteristics of WEF influenced by growing areas, impacting its suitability, equivalent to WWF, for producing fresh noodles.
A preharvest application of glyphosate on malting barley can assist in the management of perennial weed growth before harvest and serves as a harvest aid by drying down the crop. The main objective of this study was to assess the effects of preharvest glyphosate application at two glyphosate rates (900 or 1125 g ae/ha) and three application timings based on the maturity and seed moisture level (soft dough, hard dough, or mature).
The levels of glyphosate residue in barley grain were highly variable among locations and years ranging from 0 to 95 mg/kg. Glyphosate application at both rates at the soft dough stage significantly decreased the kernel weight of barley grain. Barley grain with up to 40 mg/kg of glyphosate residue exhibited adequate germination energy required for malting purposes; however, the residue negatively affected the growth of roots during the malting process. The levels of α-amylase in malt decreased with increasing levels of glyphosate residue in barley. Other malt and wort parameters were generally not affected by the glyphosate application on barley.
Too early application of glyphosate at the soft dough stage of barley grain development reduced the kernel weight and size, interfered with roots production, affected synthesis of α-amylase, and reduced the malt extract in several cases.
Results indicated that in the majority of environments, when glyphosate was applied at the recommended stage and rate, neither the maximum residue limit was exceeded nor were the germination and malting quality of barley impaired. In real farming conditions, it might be hard to achieve similar results despite adherence to the recommended timing of glyphosate application because of the nonuniform level of crop maturity in the field and/or uncontrollable environmental effects.
Fermentation has a huge potential to improve the nutritional and functional properties by using the biological activity of the grain itself. The current study was performed to optimize the conditions for the fermentation of Quality Protein Maize (QPM) and maize further; the impact of fermentation treatment on the bio-techno-functional properties of QPM and maize flour was assessed.
The technological properties, including oil absorption capacity, water solubility index, emulsion activity and stability, foaming capacity and stability, protein solubility, gel consistency, and least gelation concentration, were found to be increased with the fermentation treatment, while water absorption capacity, paste clarity, and swelling power observed a decline. The findings suggested elevated levels of all the bioactive constituents with the fermentation process. The modulations at the molecular level were confirmed by the scanning electron micrographs of fermented flour. Further, changes in the peaks of Fourier transform infrared spectra and the emergence of new peaks were also reported.
The fermentation treatment altered the techno-functional properties, bioactive constituents, macromolecular structure, and molecular interactions of QPM and maize flour.
Limited literature is available dedicated to the assessment of the nutritional, techno-functional, and phytochemical components in QPM and maize as influenced by the fermentation process. Further, changes in the structural and molecular interactions in the flour components due to fermentation treatment have not been studied comprehensively.
The deficiency of essential amino acids such as methionine, lysine, and tryptophan in maize protein presents a significant challenge in meeting nutritional demand. Comprehensive evaluation of maize germplasm for variability of essential amino acids, protein content, starch content, and β-carotene contents in grains, along with their relationships with yield and its associated traits, is a prerequisite for strengthening genetic enhancement for nutritional traits. Thus, the current study presents the profiling of 60 maize inbred lines across 11 nutritional quality and yield, aiming to identify variability in these traits and potential donor candidates for commercial breeding.
The test inbreds exhibited significant variations in the content of grain methionine (0.04%–0.28%), tryptophan (0.019%–0.069%), lysine (0.063%–0.318%), protein (9.31%–11.80%), starch (58.32%–70.88%), and β-carotene (2.38 ppm–6.79 ppm). Additionally, variations were noted in grain yield (0.87–2.52 t ha−1). Inter-relationship analyses suggested the feasibility of simultaneous selection of essential amino acids (methionine, tryptophan, lysine) and β-carotene. The germplasm stock was clustered, and potential diverse donors identified were recommended for utilization in breeding programs. Furthermore, the use of Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy for screening high methionine and high lysine lines in large germplasm based on differences in peak intensity at 2922 cm−1 and 1110 cm−1 was reported, respectively.
The multilocation experiment revealed genetic diversity in both nutritional quality and yield across the 60 inbreds. The absence of a negative correlation between the amino acids and β-carotene indicates the possibility of the development of hybrids with elevated essential amino-acid levels combined with high β-carotene content.
This is the first holistic report on the variability of nutritional quality traits coupled with yield in maize germplasm. Identified nutrient-rich inbreds will serve as valuable germplasm in maize biofortification programs. AT-FTIR is proposed as an easy screening technique and the first report, which can be employed for the initial screening of a large set of germplasm for methionine and lysine content.
Intermediate wheatgrass (IWG) is an underutilized perennial grain in the Canadian market with excellent nutritional and environmental benefits. The aim of this study was to assess the impact of the growing environment on the physiochemical and functional properties of IWG grown in three different growing locations in the Canadian prairies. IWG flours were compared between growing locations and years as well as alongside Canada Western Red Spring Wheat whole meal (CWRS-WM) and refined flour.
The proximate composition of IWG flours between years and growing locations had significant (p < .05) differences for protein, fiber, and ash content but showed little difference for starch content. Owing to differences in proximate composition, variances in mixing parameters, starch pasting properties, and protein profiles were observed. Overall IWG performed poorly in a bread system at 100% incorporation largely due to its lack of high molecular weight glutenin.
Understanding the impacts that growing location and year have on the proximate composition and therefore working parameters will aid in the development of new wheat products fortified with IWG. These products will contribute to a more resilient and diverse food system, that will provide nutrient-dense food options for consumers.
There is very limited research on IWG grown in the Canadian prairies, and this study is among the first studies focused on characterizing IWG grown in Canada.
The aims of this study were to assess the functional and phytochemical characteristics, as well as the antioxidant properties, of bran from five distinct rice varieties. Additionally, it evaluated the impact of extrusion cooking on the composition and quantity of individual phytochemicals in both free and bound states in the bran of these varieties.
The functional properties and phytochemical profiles of raw and extruded rice bran from different rice varieties differed significantly. The extrusion process significantly influenced the color, protein solubility, foaming properties, polyphenolics, and amino acid composition of rice bran. Total phenolics ranged from 3.18 to 4.80 mg GAE/g, increased by 12.6%–17% postextrusion. Similarly, total flavonoid content ranged from 15.22 to 17.37 mg RTE/100 g, with a 30%–33% increase after extrusion cooking. Throughout the extrusion process, a rise in the concentration of free phenolics accompanied by a decrease in the concentration of bound phenolics was observed.
The study revealed the impact of extrusion cooking on the distribution of total phytochemicals, particularly phenolics and flavonoids, and the levels of antioxidant activity in free and bound phenolics, as well as amino acid composition and functional properties. The extrusion cooking increased levels of free phenolics and 2,2-diphenyl-1-picrylhydrazyl activity, while bound forms decreased. Extrusion cooking variably impacted the functionality and phytochemical content of bran from different rice varieties, thus influencing their likely applications.
This study established the foundation for producing food products using extruded rice bran, offering health benefits and meeting the growing demand in the functional food sector.
