Abstract

The present invention provides a reference fingerprint of virgin olive oil, and an establishment method and an application thereof. By using UPLC-FLD, the chromatographic information of various components in the extra virgin olive oil is obtained, breaking through the limitation of establishment of fingerprints by means of conventional GC-MS method and based on the fatty acid composition of edible oil, and further solving the problem that traditional fingerprints only use a single component for determination and thus result in false positivity. Meanwhile, similarity calculation is conducted on the chromatographic information of serial extra virgin olive oil, establishing a reference fingerprint of virgin olive oil, reinforcing the polymorphism of fingerprint information, reflecting its differences from edible oil from the perspectives of the substance composition, distribution, and content of virgin olive oil, helping improve accuracy of identification, and enabling rapid, convenient and accurate identification of the quality of virgin olive oil.
