Excitation wavelength selection for quantitative analysis of carotenoids in tomatoes using Raman spectroscopy

•Raman spectroscopy was used to identify the optimal excitation wavelength for carotenoid measurement.•Tomatoes at 5 different maturity stages were used for the experiment.•The intensity of resonance Raman effect and reabsorption are different depending on the excitation wavelength.•785 nm is the su...
