This paper investigates the effectiveness of the determinations of fatty acid and triglyceride profiles on the detection of adulteration of camellia oil with 4 kinds of other vegetable oils.In our research,compared with cosine similarity of fingerprint of fatty acids and triglycerides,linolenic acid content,trilinolein(LLL)content,the difference between actual and theoretical content of triglycerides with equivalent carbon number 42(ΔECN42),(LLL/ECN42)×100 and ECN46/LLL,the parameter of(ECN44+ECN46)/LLL could be used to detect the adulteratio...
