Quali-quantitative analysis of carotenoids contained in the oil- and insoluble-fraction of the two S-CO₂-extracted oleoresins from pure tomato powder (S-CO₂ExT) and from tomato/hazelnut powder (S-CO₂ExTH). Values are expressed as μg/g of oleoresin and as percentage of the total carotenoids. Data are mean ± SD of three measures from three independent samples.
