Rapid Analysis of Bioactive Compounds from Citrus Samples by Direct Analysis in Real-Time Mass Spectrometry Combined with Chemometrics

Renowned for their nutritional benefits, citrus fruits are harvested at various stages in China for functional food production. This study introduces an innovative analytical method, DART-MS, enabling direct qualitative analysis of citrus samples without the need for preprocessing. Simultaneously, the combination of chemometrics can be applied to distinguish between three different citrus samples:
