AI Article Synopsis
- - The study evaluated the effects of adding selenium to the growth of kale, kohlrabi, and wheat microgreens, assessing various nutritional aspects like biomass, nutrient concentration, and antioxidant activity.
- - Biofortification with selenium resulted in significantly higher selenium concentrations in kale (133 μg/g) and kohlrabi (127 μg/g), compared to wheat (28 μg/g), without causing oxidative damage to the plants.
- - The selenium-enriched microgreens could help improve dietary selenium intake, addressing potential deficiencies in human diets.
Article Abstract
Kale (Brassica oleracea L. var. sabellica L.), kohlrabi (Brassica oleracea L. var. gongylodes L.) and wheat (Triticum aestivum L. cv. Bancal) microgreens were cultivated in presence of selenium 20 μmol L as sodium selenite and sodium selenate mixture. The influence of this biofortification process was evaluated in terms of biomass production, total Se, macro- and micronutrients concentration, polyphenols, antioxidant activity, chlorophylls and carotenoids levels and total soluble proteins content. The results obtained have shown a significant concentration of total Se in the biofortified microgreens of kale (133 μg Se·g DW) and kohlrabi (127 μg Se·g DW) higher than that obtained for wheat (28 μg Se·g DW). The Se uptake in all the species did not produce oxidative damage to the plants reflected in the bioactive compounds, antioxidant capacity or pigments concentration. These Se-enriched microgreens may contribute to the recommended intake of this nutrient in human diet as to overcome Se-deficiency.
