Casein contains amino acids and nitrogen needed by the body . Found in milk, 80% is characterized by white and yellow are both hydrophilic and hydrophobic molecules. Suspended in the water as hydrocolloids.The research was conducted through the fibers forming casein with Nick Tate electrolyte Spinning taste. The solvent sodium hydroxide that can be molded into a fiber This research has led PVA acts as a thickening agent, which helps make it mL solution with suspension and thicker. This research was presented the study forming fibers casein electrophoresis technique Spinning taste by the characterization of casein / PVA using scanning electron microscopy (sem) the ratio (ratio) are report.
