Abstract

This study was carried out for the development of assay method to quantify the soy protein content in meat homogenate, emulsion-type sausage and commercial meat products by Enzyme-linked Immunosorbent Assay(ELISA). The standard antigen was extracted before and after heat treatment. It was observed that the degree of reaction was not varied significantly according to the heating temperature. The recovery rate in meat homogenate and emulsion-type sausage was not varied significantly according to the heating temperature. The reaction was not interfered with fat and spices of the samples. Samples with 10% soy protein showed lower correlation than those with 2% and 5% soy protein. The recovery rate in commercial meat products showed difference individually. The correlation of some products with raw vegetable and wheat starch was relatively low.

본 실험은 육가공품에 첨가된 대두단백질(soy protein)을 정량하기 위한 면역분석법의 개발을 위해 고기 혼합물, 유화형소세지 및 시판육제품을 사용하여 정량실험을 설시하였다. 본 실험에 사용한 standard 항원을 추출과정 전과 후에 가열처리하여 반응성을 조사한 결과 가열온도에 따른 반응성 변화의 유의성은 인정되지 않았다. 고기혼합물과 유화형소세지의 대두단백 회수율에서 가열온도에 따른 반응성 변화의 유의성은 인정되지 않았으며, 지방 및 첨가된 향신료에 의한 반응성의 방해는 나타나지 않았다. 실험의 연관성은 대두함량이 높은 10% 첨가구에서 낮은 첨가구(2, 5%)보다 다소 낮게 나타났다. 시판 육제품의 대두단백 회수율은 제품간의 차이를 나타냈으며, 생야채와 소맥전분 등을 첨가한 일부 제품에서는 다소 낮게 나타냈으나, 실험을 통한 회수율의 연관성은 인정되었다.
