ORDONEZ, Alicia L; BALANZA, María E; MARTIN, Fanny R y FLORES, Cecilia A. Lycopene Carotenoide Stability in Canned Tomatoes. Inf. tecnol. [online]. 2009, vol.20, n.4, pp. 31-37. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642009000400005.
The objective of this work was to determine lycopene carotenoid stability during manufacturing process in canned peeled whole tomatoes and during its storage as final product. Samples were taken during industrial manufacturing at different process points: fresh tomatoes when they were feeding to process line, peeled tomatoes from thermophysical peeler and finished product after it passed the cooker-cooler. Samples were obtained from different manufacturing lots at three times during the 2007 harvesting season. Canned tomatoes were analyzed every three months, during one year. Lycopene was extracted with hexane-acetone-ethyl alcohol and measured by spectrophotometry at 472 nm. Statistical analysis of the results shows that industrial sterilization produces cell release of lycopene.
