Abstract
Tomato is after potato the second most consumed vegetable in the world and approximately 30 % of tomato production is consumed as processed products. Tomatoes are recommended for people suffering from diabetes, who have respiratory infections, kidney problems, constipation or gastric hyperacidity. This vegetable is usually consumed at the maximum organoleptic quality of the fruits, the quality obtained to the maturity stage. Tomatoes have a high nutritional value, due to its content of different types of nutrients: sugars, organic acids, phenolic compounds, vitamins, minerals. This paper presents the results of some quality parameters for four varieties of tomatoes (Arges 11, Arges 16, Arges 123 and Arges 20) grown in 2014 at I.N.C.D.B.H., Stefanesti, Arges, Romania. The content of some bioactive compounds with antioxidant activity (polyphenols, flavonoids, anthocyanins, and carotenoids) and the colour parameters (colour intensity, colour tint, lightness, redness, yellowness, chroma and hue angle) from these varieties of tomatoes were determined by UV-Vis absorption spectroscopy. Results obtained established the correlation between the content of carotenoids (lycopene or β-carotene) and the chromatic parameters (redness and yellowness). Since the tomato species were grown in the same conditions for agriculture, geography and climate, the results showed variability in the bioactive compounds content from the analysed tomatoes due to the influence of the variety.
