Lycopene-rich tomato paste has also been shown to mitigate UV radiation-induced elevation in procollagen (pC)-I deposition and reduction in matrix metalloproteinase-1 (MMP-1) Rizwan, M et al Br.J.Dermatol. The lycopene content of tomato products varies widely depending upon variety, ripeness of the fruit and processing methods, making it difficult to make dietary recommendations. It's full of lycopene, but is tomato juice worth drinking? Also, changes of lycopene content in tomato during storage, semidrying, and paste or juice processing have been reported (Anguelova and Warthesen 2000; Takeoka and others Lycopene is the pigment principally responsible for the characteristic deep-red color of ripe tomato fruits and tomato products. tomato paste increased serum lycopene levels by 2.5-fold (Gartner et al. The concentration of lycopene in tomato paste High intakes of tomato products containing lycopene correlate with decreased risk of prostate cancer. Compared to those not eating anything, the red tomato serum, the blood from those who ate red tomato paste, significantly decreased the prostate cancer cell’s expression of a growth-promoting gene called cyclin D1. 3. The tomato paste, giving a daily lycopene dose of 16 milligrams, was also found to reduce damage to mitochondrial DNA, a measure identified as a reliable marker of … A second study shows that lycopene from tomato paste is better absorbed by the body than lycopene from fresh tomatoes, suggesting that processed tomato products-such as tomato paste, tomato sauce and ketchup-are a better source of this antioxidant. In the 82 brands of different tomato products (tomato purée, ketchup, concentrated tomato paste, tomato juice, and whole canned tomatoes) from markets in Zagreb, Croatia, the values for lycopene content ranged from 3.80 to 52 lycopene content in tomato tissue, by measuring the scatter-adjusted absorbance (560 / 700 nm) of the tomato purees and inserting each value into the linear equation. Rapid Extraction of Lycopene and β‐Carotene from Reconstituted Tomato Paste and Pink Grapefruit Homogenates G. SADLER The authors are with the Univ. of Florida, Institute of Food & Agricultural Sciences, Citrus Research & Education Center, 700 Experiment Station Road, Lake Alfred. ity of reported lycopene content in raw tomato. Processing of tomatoes increases the biovailability of lycopene. The Benefits of Lycopene in Tomato Paste I found numerous articles online that said in 2008, researchers at Manchester and Newcastle Universities in England saw measured results in 10 volunteers that ate 5 tablespoons of tomato paste plus 2 teaspoons of olive oil every day for 3 months.

Lycopene is currently the most powerful antioxidant which has been measured in food and is thought to play a role in preventing cancer, heart disease, and macular degeneration. Adding lycopene or tomato paste … Consumption of tomato products has been associated with decreased risk of some cancer types, and the tomato antioxidant, lycopene, is thought to play an important role in the observed health effects. Malondialdehyde (MDA) content in serum samples and eggs that had been stored at 24 C for four weeks was reduced (P<0.05) by lycopene or tomato paste. A flavorful addition to many dishes, tomato paste provides nutrition, vitamins, minerals and lycopene… Educ., 1989, 66, 258. High performance liquid chromatography was employed for detecting lycopene and 5-hydroxymethylfurfural (HMF). This study evaluates the lycopene contents of fresh tomatoes and various commonly consumed tomato products (tomato paste, tomato sauce, tomato ketchup, spaghetti … The study described here focuses on a direct determination of a total lycopene content in different tomato pastes by means of the laser optothermal window (LOW) method at 502 nm. Cooking and processing tomatoes stimulates and concentrates their lycopene content, making tomato pastes and sauces a rich source. 2011;164(1):154-162. Continued Skin Health Long-term lycopene consumption is also linked with skin cancer prevention.Several studies show that people who included tomato paste … So, they fed people red tomato paste, yellow tomato paste, lycopene pills, or placebo pills, and then dripped their blood on prostate cancer cells growing in a petri dish. of Food Science and Technology, University of California Davis, CA 95616-8598 Keywords: Tomato, lycopene, color, variety, growing region. Although it has no provitamin … For example, a gradual and significant decrease in lycopene content (ranged between 19 and 42%) was reported after processing of tomatoes into paste. (2002). Thus, the best sources of lycopene are pasteurized tomato juice, tomato soup, tomato paste, tomato sauce and ketchup. The lycopene content of the tomato ranged around 89 micog/mg of dried matter based on the - HPLC analysis, values within those reported in the literature [16]. Copyright Austin Community College, 2012Experiment 9, Operational Organic Chemistry. On the other hand, the difference in lycopene content between raw tomatoes and processed tomato products is considered due to processing, such as sterilization [ 32 ]. Thus, tomato ketchup with high tomato paste content showed significantly higher lycopene content. 1997) but the same amount of lycopene, Table 1 Lycopene content (μg/g) in eight varieties of tomato ( Lycopersicon esculentum ) after different cooking times.
