摘要： Broad beans, a seasonal leguminous vegetable renowned for their distinctive flavor and high-quality plant protein, present unique opportunities for culinary and nutritional applications. To better understand the impact of various blanching processes on their characteristics, we employed headspace gas chromatography-ion mobility mass spectrometry (HS-GC-IMS) and biochemical tests to evaluate changes in color, volatile compound content, and levels of antioxidant-related substances following different blanching treatments. Our findings revealed that microwave blanching significantly influenced the a* metric and antioxidant capacity of broad beans. Specifically, we identified 44 volatile compounds in peeled broad beans and 57 in unpeeled ones. The steam-blanched broad beans retained a flavor profile similar to the control samples, characterized by relatively high concentrations of alcohols, aldehydes, and esters, contributing to a fruity and fresh aroma. In contrast, microwave blanching led to higher concentrations of aldehydes and alcohols and introduced additional odor characteristics such as mushroom, cocoa, and almond notes, enhancing the complexity of the flavor profile. This study provided the essential knowledge for further utilization of broad beans as well as the extension of their shelf life.
