Non-targeted metabolomics-mediated elucidation of metabolite changes in <i>Polygonatum kingianum</i> during traditional steaming with black beans.

ABSTRACT:

Introduction

Polygonatum is a traditional medicinal and edible plant often prepared by steaming it with ingredients like yellow rice wine and black beans. However, the metabolic changes in Polygonatum kingianum (PK) during the traditional steaming method with black beans have not been previously reported. This study aims to explore how the addition of black beans and the degree of steaming affect the quality of PK.

Methods

This study quantified polysaccharides, reducing sugars, saponins, and flavonoids in PK subjected to varied steaming cycles, while also integrating color measurement, sensory evaluation, and non-targeted metabolomics analysis.

Results

PK is rich in lipids, amino acids, sugars, flavonoids, and organic acids. Notably, we observed the prod
