Abstract

This study aimed to establish a method for qualitative identification of adulterated camellia seed oil by gas chromatography-mass spectrometry (GC-MS) combined with gas chromatography (GC). A GC-MS method was established for the rapid detection of the content of β-amyrin in vegetable oil, to realize the batch initial screening of vegetable oil samples. On this basis, the results were confirmed by combining with GC determination of fatty acid content. Results showed that the determination of β-amyrin was rapid, the detection period was short, and the linear relationship was good. The average recoveries at low, medium, and high levels were 82.6%-111.5%, and the relative standard deviations (RSD) were all lower than 5.36%. The method could be used for batch screening of vegetable oil samples. In addition, combined with GC determination of fatty acid content to confirm the results, oleic acid and linoleic acid could be used as the identification index of camellia seed oil adulteration. The method is suitable for the qualitative identification of camellia seed oil mixed with one or several other vegetable oils (peanut oil, corn oil, rapeseed oil, and soybean oil), and the adulteration detection limit is 10%.

Key words： camellia seed oil; adulteration; determination and identification; β-amyrin; fatty acid
