Lycopene, which is especially concentrated in grapefruit juice and tomato puree, is a natural carotene pigment found in fruits and vegetables. According to the results of the research, lycopene is active in preventing digestive system, breast cancer, prostate cancer, lung cancer and old age related heart diseases. Lycopene acts as an antioxidant in the human body. Lycopene helps the body repair damaged cells. As is known, antioxidants are a chemical compound that fights cancer oxidation. As the amount of lycopene increases in the blood, the oxidized compounds decrease.

The human body 02 does not produce mainly lycopene. However, this substance is readily available in the food. Although tropical fruits, watermelon and red grapefruit are rich in lycopene, 85 percent of lycopene is contained in tomato and tomato products. Tomato paste, ketchup and tomato juice are rich in lycopene. The human body receives the best processed lycopene from tomato paste, ketchup, tomato juice and similar tomato products. There are 100 mg in 85 gram tomato paste, 16 mg in ketchup, 10 mg in tomato juice, 4 mg in grapefruit and 3 mg lycopene in fresh tomatoes. However, the amount of lycopene varies according to climatic conditions, soil structure and tomato type.

Lycopene is the most effective type of carotenoid in human metabolism. There is more amount in the body than beta carotene. From a biological point of view, this increases the importance of lycopene on the body's defense system.

Lycopene determination studies are also carried out in authorized laboratories within the scope of chemical tests. In general, high pressure liquid chromatography (HPLC) is used in these studies. All over the world, tests have been resorting to this method, which provides precise results in the separation of non-volatile or easily degradable compounds at temperature. In addition, the standards published by national and international organizations are complied with.
