Chemical and volatile characteristics of olive oils extracted from four varieties grown in southwest of China

Abstract The present study was conducted to determine the quality parameters, fatty acid profile, minor compounds (pigments, tocopherols, phenolic compounds, squalene and total sterols) and volatile compounds of olive oils from four common olive cultivars (cv. ‘Koroneiki’, ‘Coratina’, ‘Frantoio’ and ‘Arbequina’) planted in China. The effect of maturation stage on the characteristics of the oils was also evaluated. All samples were classified as extra virgin according to the standards established by IOC. Statistically significant differences (p
