"초음파식" refers to a method of cooking or food preparation that utilizes ultrasonic waves. This technique can enhance the extraction of flavors and nutrients from ingredients, making it popular in modern culinary practices. It is often used in conjunction with other cooking methods to improve efficiency and taste. The process involves the use of ultrasonic transducers that generate high-frequency sound waves. These waves create microscopic bubbles in liquids, which collapse and produce shock waves. This phenomenon, known as cavitation, helps to break down food particles and can lead to a more intense flavor profile in dishes.
