Development of Technologies for Producing Phytomelanines on Waste Oil Production

Phytomelanin is a unique [M1] component of plant origin, obtained from the husks of sunflower, having photo and radioprotective effects, effectively protecting the skin from the damaging effects of UV rays of different wavelengths. Melanin is found in all living organisms, including plants. Revealed that preparations with melanin prevent ulceration, reduce the number of hemorrhages in the stomach mucosa and prevent a decrease total body weight in stress condition. The presence of melanin in food products and products contributes to their long-term storage. Water extracts stabilized with phytomelanin gives a possibility to obtain healing cosmetics that are fundamentally new in their properties. The search for ways to obtain phytomelanins from plant waste is an actual task facing the scientific community. A collective of researchers has proposed a method for producing water-soluble phytomelanins from sunflower husk, which is an oilseed waste. The main stage of obtaining is alkaline extraction, continuing at a temperature of 120 ° C for 1 h. It is offered to use a solution of caustic soda with various concentration as an extractant. The resulting extract acidified with a solution of hydrochloric acid to a pH of 1.0 to 2.0, separated, neutralized and dried. For the obtained substance confirmed the character of melanoid using qualitative reactions, and the adsorption ability with relation to methylene blue was determined. The best exemplars had activity from 50 to 79 mg / g dry matter. Via a model test system from chicken yolk, the total antioxidant activity was determined, which ranged from 10% to 28%. The resulting substance can be used as a therapeutic drug or biologically active food supplement.
