초록
본 연구에서는 난백분말과 카제인에 포도당을 첨가하여 만든 기질을 젖산균(Lactobacillus)으로 발효하여 호상의 요구르트를 만든 후, 난백분말젖산균의 생육과 산생성 및 요구르트의 품질 (관능성, 휘발성 향기 성붕)에 미치는 영향을 조사하엿다. L. acidophilus로 24시간 발효된 시료의 경우 산도는 우유 시료(대조군)에 비하여 난백분말 1-3% 시료는 유의적으로 낮았으며(p<0.05), 난백분말 시료 가운데는 난백분말의 농도를 1%에서 3%로 증가시킴에 따라 산생성이 증가하였다. 새균구는 우유 시료가
Gel-type yogurt was prepared from egg white powder (EWP), casein and glucose. The effects of EWP on acid production and growth of Lactobacillus were studied. The effect of EWP on sensory properties and volatile aroma compounds were also studied. Acid production by Lactobacillus in EWP (1-3%, W/V) was significantly lower than that by Lactobacillus in milk (control). However, the increase of EWP content from 1 to 3% increased acid production significantly, Number of viable cells of L. acidophilus at 24 hrs in milk and EWP containing samples (1-3%) was
