STUDIES ON THE NATURAL COLORES EXTRACTION FROM (MARINE ALGAE)

Abstract

Abstract The current trend for scientific research is moving towards the production of materials and natural food products to keep overall health of individuals so this research shows methods of extracting natural dyes from green algae (Ulva lactuca L) and red algae ( Plocamium cartilegineum ) & Gelidium sp, and used as colorants and preservatives in processed foods as an alternative to the industrial colors, and as a result they contain antioxidant materials at high is used as a preservative for foods. This study showed that pigments which extracted from green algae her best solvent (acetone aqueous 80%) at wavelength (450 nm ) with an average (.6090 ), followed by ( DMF 100% + Nitrogen liquid ) degree ( -196 ) under zero , when the wavelength (450 nm ), average (.631 ) and be algae in the form of dried, the other side red algae best solvent for the extraction of pigment (Distilled water) to get the red pigment, but to get the green from red algae score the best solvent (DMF 100% + Nitrogen) at the wavelength (450 nm ) average (1.335 ) , followed by ( M.A ) at the same wavelength with an average ( .988 ). The algae are processed before preparing for the extraction of the dye (soak and rinse grinding and sonication of the cells and tissues). The drying process for green was the best and freezing process red is the best Extracting the dye from algae . Been employed in the production of dyes pomegranate jelly from fruit kiwi. Because it is a treasure trove of natural dyes and carotenoids, vitamins and unsaturated fatty acids, protein and dietary fiber. That will affect positively on the overall health of individuals helps clearly to treat (obesity _ diabetes _ osteoporosis _ increase immunity and prevention of cancer ..... etc. all from algae ).
