摘要

Different cultivars of mung beans from different regions show significant differences in composition and digestive characteristics. This study conducted a comprehensive analysis of eight characteristic mung bean varieties sourced from different provinces in China, a topic not previously explored in depth, and innovatively integrated nutritional components and in vitro starch digestibility with geographical and environmental factors. The results revealed significant variations in starch digestibility among the mung bean cultivars across different regions, indicating a correlation with their nutritional attributes. These variations may be related to the combined effect of environmental factors (soil and climate) and genetic traits. Particularly, the HLJ-TL from Heilongjiang Province demonstrated superior qualities, including high protein (23.32%), resistant starch (36.00%), and low eGI (62.43). These attributes were speculated be associated with the fertile black soil, weak alkaline soil, and monsoon climate in Tailai County, rendering it a promising raw material for the production of high-nutrient, low-GI products. This study provides valuable insights for optimizing post-harvest processing, market strategies, and functional applications of mung beans.
