초록
농축대두단백으로 만든 두유를 여러 가지 정도로 가열 처리한 후 젖산균 5종을 각각 접종하여 두유의 가열처리가 젖산균의 생육과 산생성 그리고 대두요구르트의 관능성과 커드의 침전에 미치는 영향을 관찰하였다. 먼저 산생성을 보면 표준시료(비가열(非加熱)시료)에 비하여
The effects of various heat treatments of soy milk prepared from soy protein concentrate on growth and acid production by five species of lactic acid bacteria were investigated. Sensory property and sedimentation characteristics of soy yogurt prepared from heat-treated soy milk were also evaluated. Heat treatment of soy milk stimulated acid production by all cultures. Acid production was generally proportional to degree of heat treatment and acid production by all cultures except Streptococcus lactis was maximum in soy milk heated at
