SummaryIn this study, obtaining sourdough bread enriched in zinc (Zn) and selenium (Se) with biofortified whole wheat flour (BWWF) was investigated. Sourdough bread flour was blended with BWWF in the ratios of 25:75, 50:50 and 75:25. The Zn and Se contents varied from 12.06 to 43.06 mg/kg and from 80.73 to 267.58 μg/kg in the substituted flours (SFs), respectively. Gluten‐quality‐related technological and rheological properties of SFs were also determined. The BWWF negatively affected those parameters, and GlutoPeak torque before maximum and peak maximum time, alveograph energy and extensibility, sedimentation volume, gluten index and lactic acid solvent retention capacity values decreased substantially to 21.0 GPU, 27.5 s, 85.67 10−4 × J, 18.0 mm, 33.33 mL, 81.98% and 78.72%, respectively. The Zn contents of the SFs bread varied between 10.48 and 43.88 mg/kg, and the Se contents were found between 55.7 and 224.3 μg/kg. At 75% replacement, the recommended daily allowance (RDA) was obtained at 33.3% and 36.0% for selenium in adults, respectively, while it was 27.1% for zinc and 25.6% for selenium at the 50% substitution level. With the increase in substitution rates, the volumes of the SFs breads decreased from 337.5 to 516.3 mL, their organoleptic properties deteriorated, and the hardness of the breads increased from 507.5 to 3633.1 g. In the study, the whiteness index (WI) value was higher in the A yeast combination breads. The sensory properties of pore structure, taste and chewiness of the 25% substitution SFs bread were close to those of the control. Compared with control bread, all SFs bread had statistically higher (P < 0.01) ash, protein, total phenolic contents and antioxidant activity (ranging from 1.893% to 2.495%, 8.22% to 11.60%, 75.85 to 117.74 mg GAE/100 g and 8.84 to 13.34 inhibition%, respectively).

“…In this section, we initially summarize the crucial role of Se fertilizer strategies, including how to adjust the type [36][37][38] and dosage of Se fertilizers [39,40], and the application site [32,41] and timing of Se [42,43]. Subsequently, we consolidate and discuss the impacts of agronomic management strategies on Se biofortification, encompassing crop rotation [44][45][46] and intercropping [47][48][49] and soil [50][51][52] and water management [53][54][55], as well as microbial inoculation [56][57][58]. As the most accessible methods for farmers, agronomic strategies play an irreplaceable role in Se biofortification practices.…”

Selenium (Se) is an essential trace element that plays a crucial role in maintaining the health of humans, animals, and certain plants. It is extensively present throughout the Earth’s crust and is absorbed by crops in the form of selenates and selenite, eventually entering the food chain. Se biofortification is an agricultural process that employs agronomic and genetic strategies. Its goal is to enhance the mechanisms of crop uptake and the accumulation of exogenous Se, resulting in the production of crops enriched with Se. This process ultimately contributes to promoting human health. Agronomic strategies in Se biofortification aim to enhance the availability of exogenous Se in crops. Concurrently, genetic strategies focus on improving a crop’s capacity to uptake, transport, and accumulate Se. Early research primarily concentrated on optimizing Se biofortification methods, improving Se fertilizer efficiency, and enhancing Se content in crops. In recent years, there has been a growing realization that Se can effectively enhance crop growth and increase crop yield, thereby contributing to alleviating food shortages. Additionally, Se has been found to promote the accumulation of macro-nutrients, antioxidants, and beneficial mineral elements in crops. The supplementation of Se biofortified foods is gradually emerging as an effective approach for promoting human dietary health and alleviating hidden hunger. Therefore, in this paper, we provide a comprehensive summary of the Se biofortification conducted over the past decade, mainly focusing on Se accumulation in crops and its impact on crop quality. We discuss various Se biofortification strategies, with an emphasis on the impact of Se fertilizer strategies on crop Se accumulation and their underlying mechanisms. Furthermore, we highlight Se’s role in enhancing crop quality and offer perspective on Se biofortification in crop improvement, guiding future mechanistic explorations and applications of Se biofortification.

“…The selenium compounds, Na 2 SeO 4 and Na 2 SeO 3 , are most commonly used in conventional fertilizers, as they are more economical than organic Se fertilizers ( Broadley et al., 2006 ; Broadley et al., 2010 ). However, the availability of Se to plants from the soil is highly dependent on physicochemical properties, such as pH and redox potential of soil, chemical speciation, and the activity of soil microorganisms ( Lyons, 2010 ; Mrština et al., 2022 ). All these soil-related factors render the Se applied fertilizer less plant-available under prevailing field conditions ( Schiavon and Vecchia, 2017 ), thus foliar application of Se salts may be the best option for lowering the risk of Se immobilization in the soil.…”

IntroductionSelenium (Se) deficiency, stemming from malnutrition in humans and animals, has the potential to disrupt many vital physiological processes, particularly those reliant on specific selenoproteins. Agronomic biofortification of crops through the application of Se-containing sprays provides an efficient method to enhance the Se content in the harvested biomass. An optimal candidate for systematic enrichment, guaranteeing a broad trophic impact, must meet several criteria: (i) efficient accumulation of Se without compromising crop yield, (ii) effective conversion of mineral Se fertilizer into usable organically bound Se forms (Seorg), (iii) acceptance of a Se-enriched crop as livestock feed, and (iv), interest from the food processing industry in utilization of Se-enriched outputs. Hence, priority should be given to high-protein leafy crops, such as soybean.MethodsA three-year study in the Czech Republic was conducted to investigate the response of field-grown soybean plants to foliar application of Na2SeO4 solutions (0, 15, 40, and 100 g/ha Se); measured outcomes included crop yield, Se distribution in aboveground biomass, and the chemical speciation of Se in seeds.Results and DiscussionSeed yield was unaffected by applied SeO42-, with Se content reaching levels as high as 16.2 mg/kg. The relationship between SeO42-dose and Se content in seeds followed a linear regression model. Notably, the soybeans demonstrated an impressive 73% average recovery of Se in seeds. Selenomethionine was identified as the predominant species of Se in enzymatic hydrolysates of soybean, constituting up to 95% of Seorg in seeds. Minor Se species, such as selenocystine, selenite, and selenate, were also detected. The timing of Se spraying influenced both plant SeO42- biotransformation and total content in seeds, emphasizing the critical importance of optimizing the biofortification protocol. Future research should explore the economic viability, long-term ecological sustainability, and the broad nutritional implications of incorporating Se-enriched soybeans into food for humans and animals.
