The manufacture of food products anddietarysupplements using natural food pigmentsand other different natural compounds has been attracted attention in the field of modern food industry. One of the necessary and interesting naturalscompounds are carotenoids which show strong antioxidantandimmunomodulation activities and may prevent degenerative diseases as well.

The present research concerns the development and validation of a new, rapid, modern, effective and selectiveHPLCmethod for determination of carotenoids – beta-carotene and lycopene in organic extracts obtained from tomato, tangerine and orange agro industrial waste materials usingextraction techniques - supercriticalfluid and sequential ultrasonication-assisted extractions.

The method was developed using RP-18 endcappedLiChroCART4 x 250 mm, 5 μm column. The method was validated with respect to robustness, system suitability test, specificity, linearity-range, accuracy, precision, limit of detection (LOD) and quantitation (LOQ). The LOD and the LOQ are 0.081µg/mL and 0.041 µg/mL for beta-carotene, 0.034 µg/mL and 0.085 µg/mL for lycopene, respectively.

The content of each carotenoid per 1 g of dried local agro industrial waste material varies for beta-carotene 0.290 – 10.030µg (tomato peel), 0.445 – 3.972 µg (tangerine peel), 0.833 – 2.455 µg (orange peel) and for lycopene 0.418 – 143.79µg (tomato peel), 0.051 – 179.988 µg (tangerine peel), 0.091 – 0.114 µg (orange peel).
