Casein (Casein) contains amino acids and nitrogen needed by the body found in the milk of 80% characterized by white yellow has both like and don't like the water in the water molecules. Suspended in the water, a hydrocolloid (hydrocolloid) to form micelles.By casein can be used as a fiber processing (Fiber) which fiber from milk (Milk fibres) with the stimulating work of amino acids. Which good for skin and make skin moist.By using electrolysis spin Ning (Electrospinning) is a technique used in charge. Produce fibre polymer ranging in size from nanometers to micrometers to. The fiber with characteristics such as specific surface area, high (specific surface area).(aspect ratio) and porosity is tall (porosity) can be applied to various tasks, such as an electronic โตอิ decided (optoelectronic). Sensor technology (sensor technology) to change the reaction rate (Catalysis) filtering and medicine, etc. 1 [].(Polyvinylalcohol). As the system of emulsion and suspension concentrate on various (thickening agent).
