Dataset for "Determination of 2-MCPD, 3-MCPD and GE in Edible Oils by the One-Tube Alkaline Transesterification Coupled with Gas Chromatography-Mass Spectrometry"

This dataset provides the foundational data for the findings presented in the JAOCS manuscript titled “Determination of 2‑MCPD, 3‑MCPD and GE in Edible Oils by One‑Tube Alkaline Transesterification Coupled with Gas Chromatography–Mass Spectrometry.” The study introduces an efficient, rapid, cost‑effective, and low‑interference analytical method for the determination of these contaminants in edible oils. This dataset includes all primary analytical measurements used to produce the figures and support the conclusions of the paper. Data Contents Experimental Design: Optimization of mass spectrometry parameters and quantification of glycidyl esters (GE). Spectrometry Data: Spectral data with m/z 245 and 245 selected as quantification ions. Calibration Data: Calculation of GE mass derived from 3‑MCPDE conversion. Relationship to the ManuscriptThis dataset serves as the direct source for Figures 1–3 and Tables 1–3 in the manuscript. It enables independent verification of the proposed method and facilitates performance comparison between the “two‑tube” approach and conventional GC‑MS/MS methodology.
