Effect of harvest age on the quality of microgreens grown from red-fleshed dragon fruit seeds (Hylocereus polyrhizus)

Published: September 7, 2026

Abstract

Dragon fruit seeds are a nutrient-rich by-product with considerable potential for food applications. Germination is a simple and effective method for activating metabolic processes and enhancing nutritional value. This study evaluates the effects of harvest age at 8, 10, 12, 14, 16, and 18 days after sowing on the yield, moisture content, and bioactive compounds of microgreens grown from red-fleshed dragon fruit seeds. Microgreens harvested 12 days after sowing achieved the highest yield, reaching 456.52%. At this stage, vitamin C and vitamin E contents were also highest, at 1,007.6 mg/100 g dry weight and 4,683.5 mg/100 g dry weight, respectively. The findings demonstrate the potential of utilizing dragon fruit seed by-products to develop nutrient-rich microgreens and increase the value of dragon fruit processing residues.
