Abstract

The allergenicity of soybeans was analyzed using polyclonal antibodies and the blood sera of patients with soybean allergy, using fourteen different varieties of soybeans that are consumed in Korea. The study that used polyclonal antibodies having specificity for soybeans showed that while some of the fourteen varieties of soybeans contained additional protein bands indicating antigenicity, others lacked such bands, and the most antigenic protein was found in Jinpum soybeans. In comparing blood sera reactivity of four patients having soybean allergies, who had antigenicity values of 65U/ml or more according to CAP testing, the soybean varieties of Danbaek and Shinpaldal2 had the most reactivity and Daewon had the least. The result that the allergenicity of proteins in soybeans differs according to the variety of soybean, leads to the conclusion that it may be possible to reduce consumer allergic reactions to soybean products by choosing an appropriate variety of soybeans.

국내에서 소비되는 콩 14품종에 대한 항원성 검사를 토끼에서 생산된 다클론 항체와 콩 알레르기 환자 혈청을 이용하여 검사하였다. 그 결과 콩 특이성을 갖는 다클론 항체를 이용한 연구에서는 일부 콩 품종에서 항원성을 나타내는 단백질이 추가적으로 존재하거나 결여된 것을 확인할 수 있었으며, 14품종 중 특히 진품콩에서는 다른 품종보다 항원성이 강한 단백질이 확인되었다. CAP검사에 의해 콩 항원에 대한 특이 항체 값이 65 U/mL 이상인 콩 알레르기 환자 4명의 혈청을 이용한 반응성 비교에서는 다른 품종에 비해 단백콩과 신팔달2호에서 조사된 모든 콩 알레르기 환자혈청과 상대적으로 뚜렷이 높은 반응성을 나타냈고, 대원콩에서 제일 낮은 반응성을 나타냈다. 이러한 결과는 콩 품종에 따라 포함된 단백질의 알레르기성 차이가 있음을 의미하며 콩을 원료로 식품을 제조할 때 콩 품종을 고려함으로써 알레르기 반응으로 인한 문제를 줄일 수 있는 가능성을 제시한다.
