| Abstract: |
| 53 edible vegetable oil samples were collected, the glyceride composition and the contents of 3-MCPD ester and GEs were tested, and the correlation of glyceride composition and contents of 3-MCPD ester and GEs of edible vegetable oil products were analyzed. The results showed that the triglyceride content in the oil samples examined was 81.26%-99.11%, the diacylgly cerol content was 0.79%-13.94%, the monoglyceride content was ND-4.84%, and the number of samples with the triglyceride content less than 95% accounted for 52.8%, and the composition of glycerides of different kinds of oils and different oils of the same kind showed great differences. The detection rate of 3-MCPD ester was 8679%, and the detection content range was 019-14.68 mg/kg; the detection rate of GEs was 100%, and the detection range was 0.16-19.20 mg/kg; according to the limited amount index of EU, the number of oil samples with GEs content not higher than 1 mg/kg accounted for 20.75%, the number of samples with 3-MCPD ester content not higher than 1.25 mg/kg accounted for 64.15%. The contents of 3-MCPD ester and GEs in palm oil and rice oil were far higher than that in other oils, and the corresponding monoglyceride and diacylglycerol contents in these two oils were also the highest; the contents of 3-MCPD ester and GEs in soybean oil were lower, and the monoglyceride and diacylglycerol contents were also lower.However, the content of 3-MCPD esters and GEs in other oils did not show a clear correlation with the content of monoglyceride and diacylglycerol. |
