AI Article Synopsis
- The study investigates how the variety and environment affect the characteristics of lotus seeds (LS), focusing on differences in metabolites and minerals from various origins.
- A new quantification method identified 20 mineral elements in LS, while a metabolomics approach revealed 323 metabolites.
- Significant variations in mineral content were found among LS samples from seven regions, with potassium and manganese being the most abundant, leading to the identification of potential geographical markers for quality control in the food industry.
Article Abstract
The characteristics of lotus seeds (LS) are influenced by variety and environment. However, it remains unknown the difference of metabolites and elements of LS from different origins. In this study, an accurate quantification method (97-107 %) for 20 mineral elements in LS was developed, and a metabolomic method was established to identify a total of 323 metabolites in LS. Mineral composition analysis revealed significant variations in the mineral element contents among LS samples from seven geographical regions. LS were rich in potassium (14,710 mg/kg), manganese (67.19 mg/kg), with a low level of sodium (210 mg/kg). A total of 10 mineral elements and 117 metabolites (p < 0.05 and VIP > 1) were identified as the potential geographical markers of LS by integration analysis. The linear discriminant analysis model showed high prediction accuracy. This study provides strong experimental evidence to maintain the authenticity and quality of LS in the food industry.
