Comprehensive evaluation of nutrient and phytochemical profile of bok choy (Brassica rapa subsp. chinensis) at different growth stages

Abstract

Growing Concern of health-related disorder around the globe has led to need for healthy food alternatives. Green leafy vegetable can be one such alternative. As the green plant grows it goes through different stages, and each stage has its own importance in health and wellbeing. Therefore, the main objective of the study was to evaluate the nutritional and phytochemical profile of Bok choy (Brassica rapa subsp. chinensis) at microgreen, baby green and mature green stages. These
stages were analysed for there proximate and phytochemical profile. A significant difference (p<0.05) was observed in the moisture, protein, and carbohydrate content of different stages, from which microgreens were found to have higher nutrient profile. In the phytochemical assessment, phenolics and flavonoids were found to be higher in microgreens, which can be a possible reason for the higher antioxidant activity. The microgreen stage was found to have higher macronutrient content and phytochemical content which can be a reason for higher antioxidant activity.
