Foods, Effect of different pre-treatments and dehydration methods on. 159:353-360. -lycopene concentrations are not clearly determined. Special attention must be paid to light, and oxygen conditions since are the two major factors, causing lycopene degradation. In particular, it is a key component of the Mediterranean, recognized as a healthy diet, especially in comparison with, other typical diets from Northern European and American. 48 weeks. Considering the large tonnage, more than 10.5 million tons in 2003 (ERS/USDA 2003), of tomatoes processed yearly, the negative impact of the presence of defects on acceptable peeling of processing tomatoes may be are grown in the San Joaquin and Sacramento Valleys, with production centered in Fresno, Yolo, San Joaquin, Kings, and Colusa Counties. However, a need exists for better exploration of its biosynthesis, metabolic aspects, tissue distribution and bioavailability. Response surfaces for lycopene content of tomato puree for different high-pressure treatments and additive concentrations (in A and B, concentrations of NaCl or citric acid, respectively, were kept constant at level 0) (Reprinted with permission from [97]). Thus, carotenoids such as lycopene could be, more exposed to oxygen, which could have a significant, extractability of carotenoids is reduced in lyophilized ma-, compared to fresh tomatoes. stitute and International Center for Tropical Agriculture, (2010) Carotenoid stability during production and storage of, tomato juice made from tomatoes with diverse pigment profiles, measured by infrared spectroscopy. Heat, light, oxygen, and different food matrices are factors that have an effect on lycopene isomerization and autooxidation. !�����x�+���Sw7~�|�+y$oJ� ���НL_jZ��z0�E�a���G1�ߜjH6vBK�=��Z�������d��oB�1b������R"�B �s��Z��D����.���R��� ����qA'n��3�0�9}�F���r�pC�5f�+��o�j��sþ�o/���uc���x0ӳl.���s'���,0��9�a̴hÉn7�^�5f��i)ٍ�#\x啮-��I�*̫�����^�������f\jW���Z}���� � #���ԏz%]K�j�t�팣�=������8 ��i2F�;�3�+>=S�%�a��F�B�;�iZ}�o�����f���|�Xl��]�W6���MM��������Ww:�.���6���. In that way, a lycopene enhancement of, ] was observed. Hackett MM, Lee JH, Francis D, Schwartz SJ (2004) Thermal, stability and isomerization of lycopene in tomato oleoresins, from different varieties. However, disruption of food matrices (e.g., cellulose-thickened cell walls and membranes) during processing may enhance the release and solubilization of lycopene, which results in enhanced bioaccessibility and bioavailability. tional and nutritional quality of foods for long periods. Rats appear to accumulate lycopene in tissues within the ranges reported for humans, suggesting that they can be used to study effects of lycopene isomers on disease processes. These reactions could affect, bioavailability and reduce the bioactivity of these com-, pounds. 0000004097 00000 n age method since can greatly reduce enzymatic activity. Finally, no effect on β-carotene concentration was observed, regardless of the fruit developmental stage when the temperature increase was applied. In the investigated time–tem-, perature frame considered by these authors, the all-, lycopene decreased with increasing treatment time and, whereupon a constant value was reached. %PDF-1.3 %���� Most recent advances and methodologies to solve the challenges being faced during extraction, isomerization and within human body, i.e., processing, environmental and gastrointestinal stresses of lycopene, have been highlighted in this review. It is, also known as high-hydrostatic-pressure (HHP) processing, since water is the most used pressure-transmitting fluid, efficient compared with many conventional processes [, HPP is used to achieve inactivation of vegetative mi-, croorganisms by damaging their membranes, induce some, consumer-desired food attributes (i.e. The healthy properties of tomato are due, ]. The implications of these findings are not yet clear. Among non-thermal processes, peeling, and freeze-drying reported the highest lycopene degrada-, tion rates. 0000001656 00000 n J Agric Food Chem, antioxidant properties of tomatoes after processing.

Concerning to lycopene forms, all-, higher in juices made from MPEF-treated (0.1 Hz) toma-, to that juice from untreated tomatoes, with increases of, lycopene was not affected by processing tomatoes by, MPEF, probably due to its high rotational barrier for, explained by the activation of enzymes such as phytoene, desaturation reactions, each of which creating a new double, bond and extending the chromophore by two conjugated, double bonds; the end product is lycopene [, quent MPEF treatment (same conditions) of juice from, MPEF-treated tomatoes did not induce lycopene changes in, contents, respectively, after HPEF (bipolar pulses of 4, relative lycopene content of tomatoes (Reprinted with permission, lycopene slightly decreased, showing all treatments similar, The porosity of tomato products might be increased during, freeze-drying. To prepare tomato paste and pulp, the juice is further concentrated under vacuum to around 9% to 12% solids. II. Several research groups have suggested that cisisomers of lycopene are better absorbed than the all-trans form because of the shorter length of the cis-isomer, the greater solubility of cis-isomers in mixed micelles, and/or as a result of the lower tendency of cis-isomers to aggregate. Accordingly, the, ) than that of non-heat-treated samples (0.007, For the analysis of the effects of these parameters on the, lycopene content of tomato products, it is important, in mind the appropriate packaging material in order to, avoid light irradiation and permeability to oxygen and, low permeability of metalized polyester film better retained, powder compared to low-density polyester film after, Similarly, when several oxygen impermeable packages, (glass, metalized laminated cardboard, or plastic) were. Carotenes are. Roma VF and Lycopersicon esculentum var. Hence, when the relative in vitro lycopene bioaccessibility. As the processing temperature increases, there is also an increase in C vitamin loss. The United States imports greenhouse tomatoes year-round from Canada, Mexico, and the … Apart from this, the synthesis of lycopene using the biotechnological strategies to increase its production has also been mentioned. In nature, the predominant form is the all-trans isomeric form (80-97%) in tomato and tomato related products. geometrical isomers of alpha-carotene, beta-carotene, lycopene, and zeaxanthin. J Agric Food. Understanding those tech-, nological conditions affecting the lycopene content of, tomato and tomato products will lead to innovation in the, food industry in order to avoid great losses of this car-, otenoid.
