Lycopene Lycopene Lycopene (from the neo-Latin "Lycopersicum", the tomato species) is a bright red carotene and carotenoid pigment and phytochemical found in tomatoes and other red fruits and vegetables, such as red carrots, watermelons, gac, and papayas, but it is not in strawberries or cherries. Although lycopene is chemically a carotene, it has no vitamin A activity. Foods that are not red may also contain lycopene, such as asparagus and parsley. In plants, algae, and other photosynthetic organisms, lycopene is an intermediate in the biosynthesis of many carotenoids, including beta-carotene, which is responsible for yellow, orange, or red pigmentation, photosynthesis, and
Alumina effect pigment Alumina effect pigment An alumina effect pigment is a pearlescent pigment based on alumina (aluminium oxide). In the first step of the production process, AlO (Aluminium oxide) flakes with a very smooth surface are formed. The flakes are produced using a crystal growth process. They are formed in the corundum structure (α-AlO). The desired flake shape is achieved by controlled crystal growth in the axial and equatorial directions. The color purity and transparency of the effect pigments obtained by coating the AlO flakes with metal oxides can be attributed to the synthesis procedure yielding single-crystalline thin flakes The coating of
