Ultratraces of carotenes in tomato purées: HPLC-TLS study

The present study was designed to provide information about (i) the profile of carotene pigments and (ii) trace quantities of lycopene and β-carotene left in tomato purees. The ultrasensitive method comprising HPLC and thermal lens spectrometric (TLS) detection enabled us to detect as low as 0.3 and 1.1u2009ngu200aml−1 lycopene and β-carotene in puree extracts, respectively. Total concentration of β-carotene and lycopene (varying from 3 to 170u2009ngu200ag−1) in the examined tomato purees may serve as an indicator of the carotene-specific antioxidative capacity of these products. Although conventional spectrophotometry can be used to rapidly assess the quality of products derived from tomatoes, a highly sensitive and selective method such as HPLC-TLS is needed for reliable analyses of samples such as, for example, those subjected to inappropriate storage and/or handling.
