“…Unfortunately, the estimated Se intake from food consumption in many world regions is below the recommended dose, for example, 19–80 μg·day −1 in some populations of New Zealand, 7–11 μg·day −1 in the Keshan disease areas (Combs. G. F., 2001 ) in the developing countries of Asia and Africa (Gupta et al, 2021 ), and less than 40 μg·day −1 in several regions of China (Luo et al, 2021 ). Se deficiency in the diet is a global health problem (Galic et al, 2021 ), and it is estimated to be more than 1 billion people worldwide and over 70 million people in China are suffering from Se deficiency (Li et al, 2014 ; Jones et al, 2017 ).…”

In Se-deficient populations, Selenium- (Se-) enriched wheat is a source of Se supplementation, and Se content can be improved by agronomic biofortification. Thus, black-grained wheat (BGW) and white-grained wheat (WGW) (as the control) were grown in Se naturally contained soils at different concentrations (11.02, 2.21, 2.02, and 0.20 mg·kg−1). Then, a field experiment was conducted to assess agronomic performance, the concentration of microelements and heavy metals, and the uptake and distribution of Se in the BGW under the application of Se ore powder. The results showed that the grain yield and grain Se concentration of wheat respectively show a significant increase and decrease from high Se to low Se areas. Higher grain yield and crude protein content were observed in Se-rich areas. The soil application of Se ore powder increased wheat grain yield and its components (biomass, harvest index, grain number, and 1,000 kernels weight). The concentrations of Zn, Fe, Mn, total Se, and organic Se in the grains of wheat were also increased, but Cu concentration was decreased. The concentrations of Pb, As, Hg, and Cr in wheat grains were below the China food regulation limits following the soil application of Se ore powder. Compared with the control, Se ore powder treatment increased the uptake of Se in various parts of wheat plants. More Se accumulation was observed in roots following Se ore powder application, with a smaller amount in grains. In addition, compared with the control, BGW had significantly higher concentrations of Zn, Fe, and Mn and accumulated more Se in grains and shoots and less Se in roots. The results indicate that wheat grown in Se-rich areas increases its grain yield and crude protein content. The soil application of Se ore powder promotes wheat growth and grain yield. Compared with WGW, BGW accumulated more Se in grains and had a higher concentration of organic Se in grains. In conclusion, the application of Se ore powder from Ziyang as Se-enriched fertilizer could be a promising strategy for Se biofortification in the case of wheat, and BGW is the most Se-rich potential genotype.

“…Moreover, the application of Se via foliar application to peanut plants showed a positive effect in the transformation of inorganic Se to organic Se by the peanut plant. The concentration of Se increased up to 2.5 times in peanut kernel, 8 times in peanut proteins, and up to 12 times in peanut oil 28 . Whereas the foliar application of iodine to biofortify apples and pears, led to an increase at harvest (100 times) and after storage (50 times in apple and up to 400 times in pear) in iodine contents in apple and pear 29 …”

Strategies for crop nutraceutical content enhancement, a review

The increase in cardiovascular and degenerative diseases around the world, in addition to other metabolic alterations derived from an inadequate diet, have highlighted the need to consume more nutritious and healthy foods, that can also provide added value in the prevention of diseases. In this sense, nutraceutical-rich functional foods have become a sustained growing market derived from consumer demands. Different strategies have been developed to enhance the content of nutraceuticals compounds in crops and end products, as well as to increase the bioavailability of them. These strategies have been grouped in biofortification techniques (e.g., foliar, and soil application of nutrients, germination, and soaking of seeds, genetic modification of plants and crops) and techniques for nutraceutical enrichment (e.g., fermentation of food byproducts, nanoparticles, and induced post-harvest stress). The utilization of these techniques thrives a new approach for novel biofortified, and nutraceutical enriched foods that meet the needs of the most demanding and health-conscious consumers.

“…Studies have indicated that proteins in plants can be combined with inorganic Se and converted into nontoxic organic Se for absorption by the human body [ 23 ]. Moreover, the protein content of peanut kernels accounts for 25–36% of its dry weight, and is the main source of protein for human consumption [ 24 , 25 ]. Thus, Se may be effective in inhibiting Cd toxicity in peanuts and can supplement the Se required by the human body through peanuts.…”

Cadmium (Cd) pollution in soil, particularly in peanut production, is a problem that has attracted global concern and needs solutions urgently. Selenium (Se) can alleviate Cd toxicity; however, the underlying mechanisms are not completely understood. Therefore, two varieties of peanut (Arachis hypogaea Linn.), “Huayu 23” and “Huayu 20”, were chosen as the target crops for this study. A pot experiment was conducted to investigate the effects of two Se application methods combined with biochar on the accumulation of Cd and Se, and the best application method was identified. In addition, the role of Se in alleviating Cd toxicity in peanuts was studied. The results indicated that both Se and biochar decreased the Cd content in peanuts and alleviated Cd toxicity. However, the combined application of foliar Se and biochar significantly increased the peanut biomass by 73.44–132.41%, increased the grain yield of Huayu 23 by 0.60–1.09 fold, and Huayu 20 by 2.38–3.48 fold. Additionally, Cd content in peanut grains was decreased by 32.81–50.07%, and Se content was increased by 31.57–99.75 folds. Biochar can decrease the absorption of Cd from the soil, while Se can increase the accumulation of Cd in cell vacuoles by increasing glutathione and phytochelatin to decrease the movement of Cd into the grains. Therefore, our results indicate that the combined application of foliar Se and biochar can effectively promote the enrichment of Se in peanuts and suppress Cd toxicity.
