Abstract: A composition for preparing a protein-containing noodle containing a vegetable raw material and a method for preparing a protein-containing noodle using the same are disclosed. The composition for preparing a protein-containing noodle contains vegetable proteins, potato fibers, alginate, and starch. According to embodiments, low-calorie, high-protein-containing noodles with high protein content and excellent flavor may be prepared by using vegetable protein as the main raw material for noodles, and the mouthfeel and textural properties of the noodles may be greatly improved by using the vegetable proteins in combination with potato fibers, alginate, and starch. In addition, the raw material pretreatment and noodle making process are simplified, and thus, noodles may be prepared in a simple way and may be applied to mass production.
