Abstract

Mung bean sprouts are widely consumed for their nutritional value; however, the temporal dynamics of their key nutrients and bioactive compounds during germination remain underexplored, limiting evidence-based strategies for optimizing harvest time and cultivar selection. This study investigated the accumulation patterns of crude protein, crude starch, vitamin C, total polyphenols, total flavonoids, D-chiro-inositol, vitexin, and isovitexin in two new cultivars (Zhonglv 26 and Zhonglv 27) over a 168 h germination period. Our results revealed that germination consistently enhances protein, vitamin C, polyphenols, flavonoids, and D-chiro-inositol, while reducing starch, vitexin, and isovitexin. Notably, each nutrient reached its maximum at distinct time points—polyphenols at 132–144 h, flavonoids and D-chiro-inositol at 156 h, and protein and vitamin C at 168 h—enabling tailored harvest schedules for specific nutritional goals. Among the cultivars, Zhonglv 27 exhibited higher levels of most measured components, suggesting it may be a more suitable candidate for sprout production aimed at bioactive compound enrichment. These findings establish a time-resolved nutritional framework and may offer useful guidance for producing sprouts with enhanced bioactive content, potentially contributing to the development of value-added sprout products.
