Key Findings

  • Researchers at Universidad Nacional de Cuyo studied fourteen species of Brassicaceae family microgreens to develop a quality index system
  • Radish microgreens had the largest leaf area, while red mizuna had the highest yield
  • Cauliflower microgreens had the highest levels of ascorbic acid and total phenolic content
Microgreens, often referred to as superfoods, are gaining popularity due to their high nutrient levels, diverse flavors, and sustainable cultivation methods. These tiny plants, harvested just after the first leaves have developed, are not only culinary delights but also valuable additions to a healthy diet. A recent study conducted by researchers at Universidad Nacional de Cuyo investigated fourteen species of Brassicaceae family microgreens to develop a novel quality index system for scoring them[1]. The study's morphological assessment revealed that radish microgreens had the largest leaf area, while red mizuna demonstrated the highest yield. Cauliflower microgreens stood out with the highest concentrations of ascorbic acid and total phenolic content. Using advanced techniques like HPLC-MS/MS, the researchers identified over 18 different glucosinolates and phenolic compounds. Red mustard and red cabbage microgreens were found to have the highest glucosinolate content, which are compounds known for their potential cancer-preventing properties. Watercress exhibited the highest levels of phenolic compounds, primarily flavonoids, which are antioxidants that can help reduce inflammation. Broccoli and radish microgreens contained the highest levels of isothiocyanates, another group of compounds with significant health benefits. This study builds on earlier research that highlighted the phytochemical richness of Brassicaceae sprouts. Previous studies have demonstrated that certain biotic elicitors, such as methyl jasmonate and jasmonic acid, can significantly increase the glucosinolate content in various Brassicaceae species[2]. Additionally, it was found that the glucosinolate content in seeds was generally higher than in sprouts, with day 8 of germination being optimal for consumption[3]. The new study not only confirms these findings but also expands on them by providing a comprehensive comparison of different Brassica microgreens under controlled conditions. Light quality has also been shown to affect the phytochemical content and yield of microgreens. For instance, different red/blue light ratios can influence the growth and nutrient composition of various microgreens[4]. The current study complements these findings by offering a broader understanding of how different species within the Brassicaceae family perform under standard growing conditions. One of the key contributions of this study is the development of a quality index system that allows for the scoring of different Brassica microgreens based on their morphological, phytochemical, and sensory attributes. This system identified radish, cauliflower, and broccoli microgreens as the most promising species, making them excellent candidates for both nutritional research and commercial applications. The study underscores the potential of Brassica microgreens as rich sources of health-promoting phytochemicals that also enjoy favorable market acceptance. With their high levels of nutrients and bioactive compounds, these microgreens can play a significant role in improving dietary quality. The insights provided by this research are valuable for both scientists and commercial growers, offering a roadmap for optimizing the cultivation of these nutrient-dense plants. In summary, the research conducted by Universidad Nacional de Cuyo offers a comprehensive evaluation of Brassica microgreens, highlighting their nutritional benefits and market potential. By building on previous studies and introducing a novel quality index system, this study provides a robust framework for further research and commercial exploitation of these superfoods.
