Tomatoes extract

For example, the lycopene available on the market is supplied mainly by LycoRed (www.lycored.com), a company that uses a classical extraction system (ethyl acetate as solvent) and maintains a monopoly position for lycopene production on a large scale. The manufacturing of the Lyc-O-Mato oleoresin (recognized by European Regulation 258/97/EC) product of LycoRed is almost identical to the production of the food additive and includes physical operations to separate the pulp from ripe tomatoes extracted according to GMPs and lSO-9002-certified procedures. The final product contains 6 to 15% lycopene the total lycopene recovery from pulp reaches 85% and from paste around 50%.

Caffeic, p-conmaric, fernlic acids concentrations were measured in tomato extracts, after HPLC separation on RP C18 column, with formic acid and methanol as the two solvents used for gradient elntion [364]. 

LC-ESI-MS analyses allowed the detection of intact flavonol glucosides (rutin) in plasma of healthy volunteers after the consumption of tomato extract [65].

The acquisition of a two-dimensional (2D) NMR spectrum gives the advantage of obtaining information about both the chemical shifts values 8 and the coupling system of each proton (the 2D plot allows us to establish the assignments of such coupling systems). Figure 5.2.5 depicts the stopped-flow 2D COSY NMR spectrum of all-E lycopene from a tomato extract. This was recorded within 24 h with a total of 280 increments and 256 transients.

Pressey and Avants (80) separated, by DEAE Sephadex A-50 chromatography, four forms of tomato pectinesterase, with molecular weights 35,500, 27,000, 23,700, and 24,300. The number and relative amounts of these components varied considerably with ripeness and variety of tomato, and no single extract contained all four. The four forms diflFered in heat stability and response to pH and cation concentration. The fourth form, the major species in most tomato extracts, had properties similar to those of the enzyme described by Lee and Macmillan (75), whose molecular weight, however, was estimated on Sephadex G-75 as 27,500 (81),... 

The production of aldehydes and alcohols from the hydrophobic amino acids has been studied primarily in yeast (147,148,149,154) since the fusel oils produced are significant secondary products of alcoholic fermentation (149). Also important are the studies of Morgan and coworkers on the malty flavor defect in milk which is produced by Streptococcus lactis var. maltigenes (155-161). This flavor is principally caused by 3-methylbutanal (155) which is produced by transamination of leucine to a-ketoisocaproate and decarboxylation (157). Labeling experiments showed that this compound is produced from leucine by tomato extract (9, 162, 163). The corresponding 3-methylbutanol and 3-methylbutyl acetate are produced similarly in banana (145, 163). Similar transformations of valine and phenylalanine are also carried out by banana slices (145). 

The Blood Pressure Cure Secret Weapon 3 Tomato Extract... 

Even people who have been taking blood pressure-lowering drugs will benefit from this natural choice. And individuals who are determined to get their blood pressure down without drugs will benefit enormously. Tomato extract, which is rich in the antioxidant polyphenols lycopene, phytoene, and phytofluene, has been shown to reduce blood pressure for treated but not completely controlled hypertensive individuals, as well as for never-treated men and women in the category of prehypertension. Two studies have been done at the University of the Negev in Beer Sheva, Israel, by Dr. Esther Paran and her colleagues. 

The aim of the second Israeli study with tomato extract was to evaluate the potential change in systolic and diastolic blood pressure in treated but uncontrolled hypertensive patients after an eight-week treatment period. Dr. Paran and her colleagues also studied changes in nitric oxide during treatment. This was the gold standard of medical research a randomized, double-blind, crossover, placebo-controlled study. 

There were fifty-four subjects whose blood pressures remained elevated despite the use of antihypertensive drugs. Often two or three different drugs are required to completely control hypertension, but such combinations frequently lead to side effects that commonly limit patients compliance with doctors prescriptions. Dr. Paran hoped that the tomato extract would offer an alternative to adding another drug or two.

Figure 15 Quantifying salicylic acid in tomato. The full-scan mass spectra of the trimethylsilylated tomato extract contains too much background chemical noise for the salicylic acid to be satisfactorily assayed. Neither the total ion current chromatogram (a) nor the extracted ion chromatogram of m/z 276 (b) contains a discrete peak for salicylic acid, although m/z 276 is observable in the mass spectra corresponding to the retention time of the analyte (c).
