Abstract
Gel-type yogurt was prepared from egg white powder (3%, w/v), glucose (2%, w/v) and four kinds of milk products (4%, w/v). The effects of milk product on acid production and growth of Lactobacillus were studied. The effects of milk product on sensory property and volatile aroma compounds were also studied. Acid production by L. acidophilus at 24 hr in samples containing milk product was significantly lower than that by L. acidophilus in milk (p<0.05). The sample containing casein produced less acid than the other samples. Number of viable cells of L. acidophilus at 24 hr in milk and samples containing milk product was
본 연구에서는 난백분말 3% (w/v)와 포도당 2% (w/v)에 4종의 유제품 4% (w/v)를 각각 첨가하여 기질을 만들고 젖산균(Lactobacillus)으로 발효하여 호상의 요구르트를 만든 후, 첨가된 유제품이 젖산균의 생육과 산생성 및 요구르트의 품질(관능성, 휘발성 향기 성분)에 미치는 영향을 조사하였다. L. acidophilus로 24시간 발효된 시료의 경우, 산도는 우유 시료(대조군)에 비하여 유제품 첨가 시료가 유의적으로 낮았으며(p<0.05), 유제품 첨가 시료 가운데는 카제인 시료의 산도가 가장 낮았다. 생균수는 우유 시료가
