Correlation of trans-lycopene measurements by the HPLC method with the optothermal and photoacoustic signals and the color readings of fresh tomato homogenates
The trans-lycopene content of fresh tomato homogenates was assessed by means of the laser photoacoustic spectroscopy, the laser optothermal window, micro-Raman spectroscopy, and colorimetry ; none of these methods require the extraction from the product matrix prior to the analysis. The wet chemistry method (high performance liquid chromatography) was used as the absolute quantitative method. Analytical figures of merit for all methods were compared statistically ; best linear correlation was achieved for the chromaticity index a^* and chroma C^*.
