The present invention relates to an extract having anti-obesity effects of low-fat soybeans mixed with adzuki beans. The present invention relates to: a method for manufacturing an adzuki bean extract and an adzuki bean extract for food extracted by adding, to adzuki beans, a liquefying enzyme and a diastatic enzyme and performing heat treatment, thereby being liquefied and being diastatic. The method for manufacturing an adzuki bean extract according to the present invention comprises: an extraction step to add Termamyl, which is a liquefying enzyme, to low-fat soybean active ingredients and adzuki beans by using a supercritical fluid extraction method and for performing heat treatment at the temperature of 60-110°C, thereby extracting adzuki beans an enzyme decomposition step to perform enzyme decomposition on the adzuki bean extract by adding an enzyme thereto and then performing heat treatment thereonto at the temperature of 30-70°C a filtration step to filter via a pressure filter and a filter film a concentration step to concentrate the filtered adzuki bean extract via a low-temperature vacuum evaporator and a sterilization step to sterilizing the concentrate. Thus, the anti-obesity composition using low-fat soybeans according to the present invention reduces the level of blood cholesterol and minimizes destruction of nutrients during processing steps as a food ingredient in which adzuki beans are liquefied and water-soluble by an adzuki bean liquefying and enzyme decomposition step. Also, the anti-obesity composition using low-fat soybeans according to the present invention has a unique flavor and is able to be used as a food additive by removing foreign materials via a refinement step, thereby manufacturing a transparent liquefied concentrate and a powder composition.COPYRIGHT KIPO 2016본 발명은 팥과 혼합된 비만 억제 효능을 갖는 저지방 콩의 추출물에 관한 것으로, 초임계 추출방법을 이용하여 저지방의 콩 유효성분과 팥에 액화효소인 터마밀을 첨가하고 60℃~110℃에서 열처리하여 팥을 추출시키는 추출공정과 효소를 첨가하여 30℃~70℃ 열처리함에 의해 팥 추출액을 효소 분해시키는 효소
