Abstract

Lycopene C40H56 is an isomer of carotene and as a colored substance is present in red oil, bar, beets and other similar products of ferments and vegetables. Unlike carotene, there is no vitamin, i.e. physiological action, is much stronger than the carotene of technological procedures in the processing of vegetables and fruits. Particularly sensitive to the action of heavy metals (Cu, Fe and others) under their action changes the color to brown.Tomato and tomato products are the main source of lycopene, therefore these products are classified as functional food, or food that can in any way have a positive impact on the metabolic and physiological functions of the human organism. Lycopene in tomato concentrate is responsible for the red color of the tomato.Tomato is especially interesting because of its biological, physico-chemical properties, especially antioxidant activity, reduction of damage to proteins, lipids and other cellular components. Together with other carotenoids, lycopene has a potential functional effect in food. Lycopene with its acyclic structure, the long chain of conjugated double bonds and expressed hydrophilicity, shows its unique biological properties as well as its antioxidant effect.Thanks to its stereochemical properties and the ability to effectively stabilize active oxygen and free radicals, lycopene is considered to be bioantioxidant with high biological activity in various tissues in the human body. Our examination refers to the determination of lycopene in tomato concentrate by spectrophotometric methods and the results show that 90.65 mg of tomato concentrate is present in the fresh tomatoes and 55.10 mg of tomato concentrate
