A research team at Pennsylvania State University has demonstrated that adjusting zinc levels in the nutrient solution combined with controlled light exposure can significantly enhance the nutritional value of radish microgreens.
The scientists studied how different zinc concentrations affect the micronutrient profile and antioxidant activity, as well as how light alters plant biochemistry in a controlled environment.
The findings are important for microgreen producers: fine-tuning nutrition and lighting regimes makes it possible to deliberately shape the functional properties of the product — in other words, to grow microgreens with a specified level of beneficial compounds. This is especially relevant for functional food and dietary products.
