This invention discloses a method for identifying coconut oil based on MALDI-TOF mass spectrometry and a committee strategy, belonging to the field of analytical chemistry and food safety testing technology. The method includes: acquiring and preprocessing mass spectrometry data of the oil sample; extracting several characteristic peaks and their corresponding relative intensities from the mass spectrometry data; calculating the score of the oil sample based on the mass-to-charge ratio and intensity of the characteristic peaks; and identifying whether the oil sample is coconut oil based on its score. This invention optimizes the characteristic peak combination for coconut oil authenticity identification based on mass spectrometry combined with a committee strategy. The constructed machine learning classification model achieves 100% accuracy and an AUC value of 1 on the test set, solving the problems of incomplete feature extraction, instability of mass spectrometry signals, and peak drift interference in existing machine learning models, thus achieving accurate identification of edible oils. This invention has a wide range of applications and can be extended to the identification of other types of edible oils, exhibiting strong versatility and comprehensively covering the identification needs of the edible oil market.
