Development of a method using QuEChERS and LC–MS/MS for analysis of per-and polyfluoroalkyl substances in rice matrix
Science
10 Feb 2024 | Food Chemistry
To ensure food safety, a method combining QuEChERS extraction and LC-MS/MS was developed to detect 35 PFAS in rice, finding that instant rice microwaved in its packaging had lower PFAS levels compared to instant rice boiled in its packaging.
