The invention belongs to the technical field of mono/diglycerol fatty acid ester detection, and particularly relates to a method for detecting the content of 1-monoglyceride in a grease reaction process based on a near infrared spectrum. According to the method, spectral bands of grease samples with different 1-monoglyceride contents are scanned, effective characteristic spectral bands are extracted, the characteristic spectral bands have good correlation with various quality control indexes measured according to a conventional method, and the content of 1-monoglyceride in grease can be effectively detected by establishing a quantitative calibration model; according to the detection method, any toxic and harmful reagent is not needed, a detection result can be immediately obtained without treating a sample and scanning a near infrared spectrum, and the method is simple, rapid and high in accuracy and precision; the detection module is added in the grease reaction process, the change of the content of 1-monogl
