Currently, the food industry aims to develop products that both bring benefits to consumer health and are ecosustainable. Thus, much of the data has Significant produc-tion also occurs in Merced, Stanislaus, Solano, and … Journal of Food Processing and Preservation 30(1):46-55. Giovanelli and Paradiso [, isomers are more readily oxidized than all-, lycopene oxidation during storage occurred faster when a, side, those authors found that lycopene degradation was, more significant in intermediate moisture tomato pulp (air-, moisture content). The help of Jose, Fernandez Valera (Department of Food Engineering, UPCT, Spain). These treat-, ments have various goals such as microorganism or en-, zyme inactivation, decrease in the moisture content and, concentration of the product, or tissue softening in order to, separate skin from fruit. Therefore, in the presence of oxygen, the increase in, storage temperatures and/or moisture content of tomato, powders may have the most unfavourable effect, Tomato products are usually stored at room temperature, that implies great energy saving compared to refrigeration, storage. significantly change the lycopene content of tomato pulp. Food Res Int 43:2193–2200, 23. J Agric Food Chem, the antioxidant properties of fresh, freeze-dried and hot-air-dried, 20. This is considered as a very strong antioxidant; therefore, it protects the cells from the action of reactive oxygen species and prevents the cell damage. In: Britton G, Liaaen-. This has sparked, interest in knowing the effect of processing and storage of, tomato products on this carotenoid, in order to preserve it. market tomatoes, and about 95 percent (8 to 11 million tons per year) of tomatoes used for processing. MAGRAMA (2012) Avances de superficies y producciones de, cultivos, Noviembre 2012. California processing Last authors reported 18, 19, 10, and 4 %, Effect of electric field strength and number of pulses on the, ]). The pressure treatment varied from 320Mpa-620Mpa for 3 minutes at ambient conditions. However, these processing operations may be, dry weight) in the tissues of tomato fruit at different ripening stages (Adapted with permission from, cell walls and membranes) and facilitate the liberation, porate an oil phase in food formulations (e.g. Conclusively, the use of DSW would not compromise the consumer acceptance of tomatoes due to the low (not appreciable) quality differences, with even the total antioxidant capacity of these samples being increased. 0000108793 00000 n drying, such as higher energy efficiency, short drying time, and better final product quality with higher lycopene con-, desirability for infrared radiation intensity 1367, to an increase in extractability or accessibility of lycopene, Effect of Storage Conditions on Lycopene Content, Storage of tomato products may contribute to lycopene loss. The kinetics of lycopene, degradation followed a first-order reaction with a reaction, rate constant dependent on product moisture content, in, addition to temperature. Novel trends to improve lycopene stability by micro- and nano-encapsulation and addition of antioxidants are also included to examine their efficacy to protect against light, heat, oxygen and other oxidative processes. Woodhead Publishing Ltd and CRC, dation kinetics of lycopene, lutein, and 9-, juice induced by thermal and pressure processing. The most common processed products are tomato purée, tomato sauce and whole tomatoes in purée. Moreover, the total soluble solids content (TSS; °Brix) was higher when manure (M) was applied.

The first process was the, concentration (by evaporation) of tomato pulp from initial, final moisture content, whereas the second one was the, spray-drying of tomato pulp. and antioxidant content of tomato cultivars following forced-air, drying. But lycopene content can be enhanced if these parameters are properly controlled, aiding in the disruption of cells containing lycopene hence increasing content, solubility and bioaccessibility of lycopene. Today's consumers seek processed products that are minimally processed and have retained their overall quality. Lycopene degradation and isomerisation in tomato dehydration. In: Jongen W (ed) Fruit and vegetable pro-, cessing: improving quality. Spray-drying consists in a liquid or paste food that is, atomized into droplets and contacted with hot air. 0000003413 00000 n freeze-drying conditions on shrinkage and porosity of dehy-, drated agricultural products. However, nutritional and sensory, qualities may be reduced in a different degree depending, on the drying method used. Key words: tomato, processing, storage, C vitamin. tional and nutritional quality of foods for long periods. J Food Sci 69:536–541. Special attention has been paid to those technological conditions which may affect the lycopene stability, particularly those able to enhance the cis-forms content that have greater bioavailability than all-trans lycopene isomers. Tomato varieties are classified as determinate or … Journal of Food Science and Technology -Mysore-. It is a hydrophobic and, acyclic carotenoid possessing 11 conjugated and 2 non-, conjugated double bonds, and is located in the photosyn-, thetic pigment protein complex of the thylakoid membrane, gated double bonds makes lycopene susceptible to enzy-, matic (intestinal enzymes) or chemical (i.e. 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. tomatoes are bred for higher solids for use in tomato sauce and paste. ]. [, found that tomato puree stored under light conditions, and duration of the light irradiation increased. For, example, our laboratories conducted a study over the ly-, copene content of different commercial tomato products, data showed no significant lycopene content changes dur-, In some circumstances, room storage temperatures may, greatly increase due to conditions such as uncontrolled, storage during summer months in warm areas or non-re-, frigerated transport. Lavelli V, Kerr W, Sri Harsha PSC (2013) Phytochemical sta-, bility in dried tomato pulp and peel as affected by moisture, 62. Little information is known, about domestic cooking procedures that are involved after, commercial tomato products acquisition, such as mi-, crowave heating, boiling, frying, in order to know the real, lycopene quantity that the consumers are ingesting.
