| Sumario: | The carotenoid contents in Brazilian tomato produc0ts were previously determined at our laboratory by using raw material. The data regarding the development of new products, the advances on processing technologies and analytical techniques, need to be updated. In this context, the present study was carried out in order to determine the carotenoid contents of processed tomato products by means of HPLC. Samples of ketchup, sauce, paste, pulp and dried tomato were purchased at supermarkets in Campinas, Brazil. For each product, five different lots from each of the three brands (a total of 65 samples) were purchased, each lot consisting of three randomly collected packages. The lycopene and β-carotene concentration ranges (μg/g) were 188-261 and 9.3-13 for paste, 111-203 and 5.1-7.0 for ketchup, 77-117 and 4.4-7.3 for pulp, 93-112 and 5.1-6.4 for sauce, 231-471 and 7.0-25 for dried tomato, respectively. Dried tomatoes, which were analyzed for the first time, showed the highest lycopene and lutein concentrations. β-carotene contents in the paste and lycopene contents in tomato paste and in ketchup samples analyzed by the present study were higher than those obtained in the previous investigation. |
