Abstract
This study was carried out to develop a new processing method for the production of yeast autolyzate (YA) by which the yield and the quality could be improved, compared to the conventional method. The result indicated that 85.3% of yeast cell walls treated with glucanase and protease was ruptured by homogenizing at 10,000 psi. Alkali treatment, however, was not effective in disintegrating yeast cell walls. Optimum conditions for autolysis of ruptured yeast cells, obtained with help of response surface methodology (RSM), were pH 7.0,
이 연구는 재래방법과 비교하여 수율이 높고 품질이 향상된 효모 자가분해들의 제조방법을 연구하는데 그 목적을 두었다. 제빵용 생 효모에 glucanase와 protease의 복합효소를 작용시킨 다음, 10,000 psi의 고압으로 균질하면 약 85.3%의 효모 세포벽이 파손되었다. 세포벽이 파손된 효모를 사용하여 자가분해 시키는데 가장 적당한 조건을 반응 표변방법(RSM)을 이용하여 조사한 결과는 pH 7.0, 온도
