lycopene content in fresh tomato

The thermal treatment of carotenoids facilitates, the breakdown of strong cell walls causing the, Journal compilation © 2008, Blackwell Publishing, bioavailability of lycopene to increase (Gartner, at a lower temperature than normal had about ten, times the lycopene content compared with com-, The purpose of this study was to determine if, there is any difference in the content of lycopene, both in fresh and processed tomato products. An isomerised tomato oleoresin with a minimal content of the most unstable 13Z-lycopene could be obtained by refluxing tomato oleoresin in ethyl acetate for 1 week. Cooked tomato products may be preferable to the raw vegetable or juices derived from tomatoes bearing on absorption of the active principles. This study found lycopene levels from ingesting tomato paste were 2.5 times higher than eating raw tomatoes! The compari-, son within one group required larger sample sizes, and different brands. The most important dietary sources of lycopene for the human are tomatoes and tomato products. From previous experiences, these methods provide reliable results, with a one-step direct extraction, quite simple preparation of the samples, and short run times for the quantification of lycopene present in the tomato products. muslin cloth. Z-value, Q10, and activation energy for the degradation of lycopene were also determined. Roma VF. of lycopene when System 1 was used . New Candidate is Named in Dietary. Unlike standard, HPLC, this method was capable of separating, 5-cis and all-trans isomers. Geographic pathology has provided important data that populations with a regular intake of tomato products, such as in the Mediterranean region, have a lower incidence of the chronic diseases noted. Its peculiar structural and chemical features are responsible for its various pharmacological and biological activities. These results indicated that all of the considered parameters had effected on the yield of lycopene significantly, and the optimum extraction conditions were as follows: extraction time duration 20 min; ratio of solvent to material 2:1; extraction temperature 25 °C; ultrasonic power 200 W; ultrasonic frequency 46–48 kHz. From the 17 The absorbance was, blank (Figure 1). Christine Gartner, Wilhelm Stahl and Helmut Sies. Therefore, statistical signifi-, parison between two groups or more did not, require a certain sample size; therefore, statistical, Four processed tomato products were tested to, determine significant differences in their lycopene. Final sections cover applications of microbiology and biotechnology in drug discovery. The main causes of tomato lycopene degradation during processing are isomerization and oxidation. There were no significant differences in lyco-, pene concentrations between cherry and Roma, The cis isomer showed no significant difference, in lycopene concentration between Roma and, differences resulted in the lycopene concentration, between the two tomato varieties. One-way analysis of variance (ANOV, was used to identify significant differences, between samples. (http://www.cnmp.ro/ceex/comp2_oct/oferta.php?id=11). for De Rica and Roma purees respectively. ... Lycopene is particularly susceptible to degradation when exposed to excess light and heat because of its structure with a long chain of conjugated double bonds (Minhthy and Steven 1999;Lee and Chen 2002;Chang and Liu 2007; Consumption of tomato and tomato products is correlated with a reduced incidence of a number of diseases. ABSTRACT Lycopene bioavailability from a single dose of fresh tomatoes or tomato paste (23 mg lycopene) ingested together with 15 g corn oil was compared by analyzing carotenoid concentrations in the chylomicron fraction. Infected plants were scored for galling on a 0-5 rating scale. The conjugated polyene chains are responsible for its unstable and electrophilic attacks against free radicals because this double π electron system reduces the energy requirement for the oxidation of electrons in each double bond. Epidemiological studies as well as laboratory experimentation have yielded sound data and evidence in support of the fact that vegetables, fruits, and tea and specific antioxidants therein account mechanistically for inhibition. Analyses showed a considerable decrease in lycopene concentration and decimal reduction time (D-value), and a significant increase in the thermal degradation rate (k) during heating from 70 to 100 °C. protection. The values however, decreased significantly is (p<0.05) at the second week of storage from 4.01% to 1.19% for De Rica puree and 3.44% to 1.89% for Roma puree. Absorption of lycopene requires that it be combined with bile salts and fat to form micelles. implications for human health and disease. Apo-6’-, 8’-, 10’-, 12’-, and 14’-lycopenals were detected and quantified in all food products tested, as well as blood plasma. METHODS AND RESULTS: Lycopene in tomato was extracted with hexane likes other carotenoid components using 500 mg of dried powder sample. The underlying mechanisms of origin and evolution of diosgenin biosynthesis in plants remained unclear. Interconversion between the isomers was observed in all systems with 13Z-lycopene being the least stable. Evaluation of the Evidence on the Role of Tomato Products in Disease Prevention, Sanos y Fuertes: Healthy & Strong Obesity Prevention Program, Quantification of apo-lycopenals in food products and human blood plasma. Significant differences were observed in, HPLC lycopene concentration (mg/100 g) in mean. The lycopene content in pulp and peel of five fresh tomato cultivars, most common on Croatian market, was determined by spectrophotometry and the high-performance liquid chromatography (HPLC). Thus, in humans, the bioavailability of lycopene is greater from tomato paste than from fresh tomatoes. These similar recoveries over the explored concentration ranges confirm that the application of established extraction method is unaffected by differences in matrix composition of the samples. Based on these findings, we recommend using non-destructive NIR spectroscopy as an effective tool for predicting tomato fruit quality during harvest stage and postharvest processing. Lycopene in tomatoes and tomato products consists predominantly of all-trans-lycopene (35-96% of the total lycopene content) and low levels of cis-lycopenes (1-22% of the total lycopene content) (Schierle et al., 1997). For analysis of lycopene we used a fast and simple spectrophotometric method, at 472 and 502 nm, in hexane:acetone:ethanol extract. Juice was obtained by filtering the blinded pulp through a, Lycopene, shows an antioxidant capacity twice more than β-carotene, which is why its presence in the diet is considered of great interest. In the first group there were 521 children aged 12-15 years, and in the second one there were 204 healthy adults aged 25-60 years. The same was calculated for lycopene cis-isomers, but only the AUC response for the cis-isomers was significantly higher after ingestion of tomato paste (P < 0.005). Thus, the best sources of lycopene are pasteurized tomato juice, tomato soup, tomato paste, tomato sauce and ketchup. Also included are classifications of crude drugs, herbal remedies and toxicity, traditional and alternative systems of medicine, nanotechnology applications, and herbal cosmeticology.
