“…In addition, these contents are in agreement with those reported in a previous study (0.053 ± 0.018 µg/g) for Brassica rapa [14]. Due to chemical similarities between Se and S (the two elements are part of the same group of the periodic table ), it has been highlighted that an increase in Se accumulation in plants might affect the synthesis of S-related compounds [13], among them glucosinolates. Charron et al [37] and Toler et al [38], in Brassica oleracea species, observed a decrease in total glucosinolate concentrations when different hydroponic solutions were supplemented with increasing concentrations of sodium selenate.…”

“…Among the inorganic micronutrients, Se plays a relevant role in human nutrition, forming part of the active site of glutathione peroxidase, one of the main antioxidant enzymes [11,12]. This trace element can interact with S (of glucosinolates) due to their similar physical and Foods 2022, 11, 350 2 of 13 chemical characteristics and their close association with plant metabolism [13]. Secondly, these plants have proven to be a good dietary source of Ca [14].…”

In northwest Spain and Portugal, there is a long tradition of cultivating B. rapa subsp. rapa to obtain turnip greens and turnip tops. Brassica rapa L. subsp. rapa (turnip greens and turnip tops) were grown under conventional and organic conditions in two Farms in southern Spain. Glucosinolatescontents were higher in Brassicas grown under conventional conditions than those grown under organic ones. Average Ca total and bioaccessible contents ranged between 14.6–23.4 mg/g; 8.9–12.0 mg/g for turnip greens and 6.4–8.9 mg/g; 4.3–4.8 mg/g for turnip tops. According to these concentrations, an intake of 100–200 g (fresh weight) of the studied Brassica rapa fulfills Ca dietary reference intakes (DRI) (considering the total content data) and complies with 72–100% Ca DRI percentage (considering the bioaccessible data). Se concentrations ranged between 0.061–0.073 µg/g and 0.039–0.053 µg/g for turnip greens and turnip tops respectively. Se bioaccessibility values were high, with percentages of around 90%. Finally, the total glucosinolate content ranged between 13.23–21.28 µmol/g for turnip greens and 13.36–20.20 µmol/g for turnip tops. In general, the bioaccessibility of the total glucosinolates analyzed in this study was high, with mean values of around 73% and 66% for turnip greens and turnip tops, respectively. Brassica rapa vegetables grown under both organic and conventional conditions in southern Spain are an excellent dietary source of Ca, Se, and glucosinolates with a high bioaccessibility.

“…Selenium (Se) is an essential nutrient for human and animal life, but for higher plants its importance is still not confirmed. However, its venifical role in broccoli biofortification, and production of crop and/or sprouts has been confirmed by many researchers such as Bañuelos et al (2016), Tian et al (2018), El-Ramady et al (2020), and Mao et al (2020). Selenium biofortification can enhance crop tolerant to heavy metals stress (Ghorai et al 2022).…”

UTRIENT deficiency on cultivated plants may lead to human malnutrition when consumes these plants. So, the biofortification is a promising approach in increasing several crops in their contents of essentials nutrients for human health like selenium (Se). The current study focused on using two different sources of Se-fertilizers for biofortifying broccoli under nutrient deficiency stress in sandy soil. The applied doses of selenium in each form were 10, 20, 30, and 40 ppm in the form of mineral and biological nano Se-fertilizers. The vegetative parameters and yield of broccoli were determined. In general, the highest growth and yield components were attained for applying the dose of 30 mg Si L -1 for both the soluble and nano Se-forms. The studied parameters included fresh and dry weight of leaves and broccoli head, head diameter and its length gave the highest values when the dose of 30 ppm from both Se-fertilizers applied. The content of N, P, K, and Se nutrients significantly increased by increasing applied Se-doses till 40 ppm in both Se-fertilizers except P. The harvested yield of head broccoli was obtained after applied dose of 30 ppm in case of both Se-fertilizers, with an increase rate for mineral Se-fertilizer 60.1 and 57.2%, whereas were 51.8 and 47.4% for nano-Se fertilizer for both seasons, respectively. The biological Se-nanofertilizer may be is preferable for a safe biofortification. The most distinguished findings in the current study that producing biofortified broccoli rich in Se for human health can be achieved under grown in sandy soils or nutrient deficiency stress. Further studies are needed to answer more open questions regarding producing a safe and healthy food for human nutrition.

“…Once the reaction temperature is 40 °C and pH = 7.0, myrosinase can efficiently degrade sulforaphane to SFN in 25 min, the yield is 0.57 mg/mL, and the corresponding SFN conversion efficiency is 89%. However, intestinal myrosinase is also affected by epithiospecifier protein (EP) and sulfur–selenium interaction(S–Se) in the process of SFN formation [ 48 , 59 , 60 ]. EP interferes with the production of SFN, while S–Se induces the expression of myrosinase gene to produce more myrosinase.…”

Sulforaphane (SFN) was generated by the hydrolysis of glucoraphanin under the action of myrosinase. However, due to the instability of SFN, the bioavailability of SFN was limited. Meanwhile, the gut flora obtained the ability to synthesize myrosinase and glucoraphanin, which could be converted into SFN in the intestine. However, the ability of microorganisms to synthesize myrosinase in the gut was limited. Therefore, microorganisms with myrosinase synthesis ability need to be supplemented. With the development of research, microorganisms with high levels of myrosinase synthesis could be obtained by artificial selection and gene modification. Researchers found the SFN production rate of the transformed microorganisms could be significantly improved. However, despite applying transformation technology and regulating nutrients to microorganisms, it still could not provide the best efficiency during generating SFN and could not accomplish colonization in the intestine. Due to the great effect of microencapsulation on improving the colonization ability of microorganisms, microencapsulation is currently an important way to deliver microorganisms into the gut. This article mainly analyzed the possibility of obtaining SFN-producing microorganisms through gene modification and delivering them to the gut via microencapsulation to improve the utilization rate of SFN. It could provide a theoretical basis for expanding the application scope of SFN.
