METHOD FOR EXTRACTING COLLAGEN USING ULTRASONIC WAVES, AND APPARATUS THEREFOR

摘要

The present invention relates to a method for extracting collagen using ultrasonic wave generator. More particularly, the present invention relates to a method for extracting collagen, comprising: a first step of treating fish skin with ultrasonic waves in the presence of an acid solution to obtain collagen extracts; a second step of separating collagen and the ultrasonically treated fish skin from the collagen extracts; and a step of repeating the first and second steps for the ultrasonically treated fish skin to further extract collagen. In addition, a collagen separation apparatus using ultrasonic waves according to the present invention comprises: a sample tank in which fish skin is accommodated; a separation unit which receives fish skin from the sample tank, separates collagen from the fish skin, and supplies the separated collagen back to the sample tank; and a unit for generating ultrasonic waves, which is connected to the separation unit to generate ultrasonic waves in order to separate collagen from the fish skin. The method for extracting collagen according to the present invention may enable collagen to be extracted using an acid solution having a lower concentration than those used in existing methods, may enable collagen to be extracted at a high yield rate, and may enable collagen having a high molecular weight to be extracted while maintaining the basic structure of the collagen, and not in the form of collagen hydrolysate.
