Tomatoes organ concentrations

The viscosities of the continuous media can be expected to depend on their composition, viz., sugar and pectin content. Correlations in terms of the relative viscosity, T)r, can be used. However, the viscosity of the dilute aqueous solutions of organic acids and salts is generally not known. For relatively low magnitudes and narrow ranges of sugar concentrations such as the case of the continuous media of apple sauce and tomato concentrates, good correlations were obtained with just the pectin content as the independent variable ( 1, 44) ... 

Lycopene oxidation products have been extensively studied by Khachik and coworkers [1, 30-33] two oxidative metabolites, 2,6-cyclolycopene-1,5-diols A and B, present in tomatoes at very low concentrations were identified in human serum, breast milk, and organs (prostate, lung, liver, colon, breast). Recently it has been suggested that the presence of these products may result from the in vivo antioxidation properties of lycopene, and they have been proposed as potential markers of oxidative stress [34].
