Edible oil analysis method, recognition system, method for generating library, and data carrier

Abstract

The present disclosure provides a method and system for analysing one or more edible oil samples. In an embodiment the disclosure provides for calibrating the matrix-assisted laser desorption/ionisation mass spectrometry (MALDI-MS) data obtained for one or more edible oil samples to obtain calibrated spectral data; and comparing the calibrated spectral data derived from the one or more samples against a library of calibrated MALDI-MS spectra for a plurality of edible oil samples to determine the most likely composition of the one or more edible oil samples. 本发明提供一种用于分析一个或多个食用油样本的方法和食用油样本识别系统。在一个实施例中，本发明提供：校准针对一个或多个食用油样本获得的基质辅助激光解吸/电离质谱法(MALDI‑MS)数据以获得用于一个或多个食用油样本的校准的谱数据；以及将所述校准的谱数据与用于多个参考食用油样本的校准的MALDI‑MS谱的库进行比较以确定一个或多个食用油样本的最可能组成。本发明还提供一种产生用于多个不同类型的多个参考食用油样本的基质辅助激光解吸/电离质谱法(MALDI‑MS)数据的库以用于识别除所述参考食用油样本外的样本的方法以及一种其上具有指令的数据载体。
