Quantifying biochemical quality parameters in carrots (Daucus carota L.) - FT-Raman spectroscopy as efficient tool for rapid metabolite profiling.

Application of FT-Raman spectroscopy for simultaneous quantification of carotenoids, carbohydrates, polyacetylenes and phenylpropanoids with high bioactive potential was investigated in storage roots of Daucus carota. Within single FT-Raman experiment carbohydrates, carotenoids, and polyacetylenes could be reliably quantified with high coefficients of determination of R(2)>0.91.
