The chlorophyll and carotenoid content of virgin olive oils from five varieties harvested at varying degrees ripeness were determined. Colors evaluated the chromatic ordinates L*, a*, b* absorption spectrum. Oil color changes for different or stages are directly related to pigment a* values. statistical study made on both series parameters proves that there is a good correlation between them. have one best coefficients (r) easily measured. This methodology evaluates content, an additional attribute evaluation oil quality.
