“…Along with carotenoids, other antioxidant compounds present in tomatoes, including ascorbic acid, tocopherols and phenols, play a determinant role in disease prevention. 1,3 In recent years, extrusion has become one of the fastest growing food processing operations. Due to the reduction of microbial loads, the prevention of endogenous enzymes, extrusion technology improves the safety and quality of intermediate and final products.…”

The aim of this research was to investigate the influence of the addition of tomato powder (TP) to corn grits at levels 4, 6 or 8 % and the addition of ascorbic acid (AA) at levels 0.5 and 1 %, on total polyphenol content (PF), and antioxidant activity of the extrudates. The hardness and the expansion ratio of the extruded products were also tested. Mathematical models that describe the influence of additives on the mentioned properties were also determined. Extrusion was performed at two temperature regimes: 135/170/170 °C and 100/150/150 °C. Lower temperature regime led to increased hardness and the expansion of extrudates. The addition of tomato and AA led to decreased hardness and the expansion at both temperature regimes. The addition of tomato increased PF and AA compared with pure corn extrudates. Greater degradation of PF and AA was at lower temperature regime. High correlation between PF and AA was demonstrated at both extrusion temperatures.

“…Various interactions are known to occur when plants are exposed to unfavorable concentrations of more than one element [59]. As indicated from the present study the tissue concentrations of highvalue metabolites, such as vitamin C, phenolic compounds, flavonoids, Lycopene and β-carotene and other antioxidant compounds are variable under environmental stresses that may elicit the biosynthesis/ catabolism of stress responsive molecules [56].…”

Current knowledge on the basic radionuclide tolerance indicates that plants may develop mechanisms preventing the damaging effects of radionuclide stress. The radionuclides content was determined in the Mediterranean coastal black sand soil and in the edible portions of the four food crop plant species, viz., Eruca sativa, Lycopersicon esculentum, Pasidium guajava and Mangifera indica. Biochemical and nutritional constituents were assessed to elucidate the possible effect of radionuclides on the edible portions of the plants. The ability of the four study plant species to accumulate Uranium and Thorium in their edible portions from the coastal black sand soil is higher than that absorbed from the inland agricultural soils. The nutritional constituents were affected by the high concentrations of Uranium and Thorium in the plant tissues. The total protein, moisture content, total phenolic compounds, total chlorophyll, total carotenoids, β-Carotene and Lycopene were positively correlated with Uranium and Thorium concentrations in the plant tissues, while the mineral content, vitamin C and total flavonoids were suppressed by high concentrations of Uranium and Thorium in the plant tissues. The fluctuations in the biochemical or nutritional constituents of the plant edible portions are considered an important defense mechanism to control the redox state of the cells accumulating radionuclides with high levels.

“…TheLycopene is a red-colored carotenoid and its content differs in tomato varieties and increases with ripening of the fruits. Next to ascorbic acid and β-carotene, lycopene is one of the main antioxidants in ripe tomatoes (Clinton, 1998;Sies and Stahl, 1998;Ilahy et al, 2011).…”
