Pepsin, papain 및 trypsin 처리 참깨박 단백질의 기능성의 변화를 조사한 결과 용해도에 있어 pH 4에서 2%의 대조군에 비해 $53{sim}94%$까지 뚜렷한 증가를 보였으며, trypsin에 의한 10%, 20% 가수분해도 처리군은 등전점에서 약 6배, papain에 의한 10% 가수분해도 처리군은 약 4.5배 가량의 유화능의 향상을 보였다. 기포 형성력은 각 효소 처리군의 30% 가수분해도 처리군의 알칼리 영역을 제외한 나머지 영역에서 전반적인 증가를 보였다. trypsin, papain 처리군의 겉보기 밀도와 수분 흡착력은 약 0.1 g/ml와 $0.3{sim}0.7;ml/g$ 정도 감소하였으나, 유지흡착력은 약 1 ml/g 정도의 증가를 보였다.
Effect of enzymatic modification with pepsin, papain and trypsin was studied on functional properties of isolated sesame meal protein hydrolysates. Solubility of protein hydrolysates distinctively increased from 2% to $53{sim}94%$ at pH 4. Emulsifying properties showed marked increase 6 fold and 4.5 fold at degree of 10%, 20% hydrolysis by trypsin and degree of 10% hydrolysis by papain. The emulsion stability of the protein was unstable by heat treatment for 30 min. at $80^{circ}C$. Foaming properties were also enhanced by enzymatic hydrolysis except at degree of 30% hydrolysis. Bulk density and water absorption of protein with trypsin and papain decreased about 0.1 g/ml and $0.3{sim}0.7;ml/g$, but oil absorption was increased about 1 ml/g.
