Embodiment
[0028] Embodiment: The present invention discloses a method for identifying the quality of edible oil by low-field nuclear magnetic resonance, and its specific implementation steps are as follows:
[0029] 1) Sample test analysis: Transverse relaxation analysis of genuine oil and inferior oil is carried out through CPMG sequence, and the one-dimensional inverse Laplacian algorithm is used as the inversion algorithm of transverse relaxation time spectrum to obtain the relaxation values of genuine oil and inferior oil. Relaxation time spectrum, if the relaxation time spectra of the two do not completely overlap, conduct transverse relaxation analysis on their mixed oil, and get the relaxation time spectrum; if the non-overlapping part of the genuine oil and the inferior oil is in the mixed oil If it still exists and is proportional to the inferior oil content in the mixed oil, this part is selected as the oil quality identification standard; if the non-overlapping part of the g...
