The present invention relates to a natural color expressed pig trotter and a manufacturing method thereof and, more specifically, to a field of coloring technology for conventional foods including pig trotters, capable of performing excellent natural coloring without using pigments, wherein some companies use onion skins to express the color based on the public opinion that a process of adding industrial color raw materials when processing pig trotters to form a dark brown color is harmful to a human body, but it is difficult to obtain a color as dark as desired by the industry, and thus some companies still use caramel pigments. The present invention has been variously developed in the market, and is for the development of a technique intended to solve a project of developing an ingredient capable of removing disgusting odor and obtaining a dark brown color as desired with the development of new seasoning by using herbal medicine. The means of solving the problem was to use a new material capable of carrying out a pig trotter coloring method and suppressing odor of pigs by utilizing purple beet and Greyblue spicebush bark which are natural materials. If a natural color can be newly expressed by the present invention, the avoidance of a certain group of people can be eliminated, and a belief is given to the food industry in which the alcohol culture is developing due to the improvement in living standards, such that new wind is brought to the traditional market or the traditional food industry while satisfying the desire of the food industry with the growing sales. Therefore, it is expected to bring about an economic effect of reducing the consumption of foreign currencies by utilizing all the abandoned parts instead of increased meat food production.COPYRIGHT KIPO 2017본 발명의 천연색상 발현돈족과 이의 제조방법은 그동안 족발가공을 공업용 색상원료를 첨가하여 짙은 암갈색을 형성시키므로 인해 인체에 유해하다는 여론에 의거하여 일부 업체에서 양파껍질을 활용하여 색상을 발현시키기고 있으나 색상이 업계에서 원하는 만큼의 짙은 색을 얻기가 어려워 일부 업체에서는 아직까지도 캐러멜색소를 사용하고 있기에 이를 사용하지 않고도 훌륭한
