Abstract

Yogurt base was prepared from skim milk added with 0.1, 0.3 and 0.5% (w/v) garlic powder and fermented with Lactic acid bacteria (the mixed strain of Streptococcus thermophilus, Lactobacillus delbrueckii subsp. bulgaricus) at $42^{\circ}C$ for 24 h. The yogurt products were evaluated for acid production such as pH and titrable acidity, number of viable cell, viscosity, color value and sensory properties. The titrable acidities of yogurt added with garlic powder were higher than that of control(0.73%). There was no significant difference in viable cell counts among samples except 0.3% garlic powder. The viscosity of 0.5% garlic yogurt was the highest than any other garlic yogurt. There was no significant difference in color difference among experimental groups. The overall sensory scores of yogurt added with 0.1% and 0.3% garlic powder were not significantly different with those of control. These results suggest that the added amounts of garlic powder to prepared yogurt are adequate below 0.3%.

마늘 분말을 첨가한 요구르트의 품질특성 평가를 위하여 탈지분유에 0.1~0.5%(w/v) 마늘 분말을 혼합하고 Streptococcus thermophilus와 Lactobacillus delbrueckii subsp. bulgaricus의 혼합균주를 접종하여 $42^{\circ}C$ 에서 24시간 배양하였다. 마늘 분말 첨가량에 따른 유산균의 생육정도, 요구르트의 이화학적 및 관능적 특성 을 검토하였다. 마늘 분말이 첨가된 요구르트의 적정산도는 0.78~0.81%로 마늘 분말이 첨가되지 않은 대조군(0.73%)보다 높았다. 마늘 분말을 첨가한 요구르트의 생균수는 0.3% 첨가군에서만 상대적으로 낮았고 여타 실험군은 대조군과 유의적인 차이가 없었다. 마늘분말의 첨가량이 증가함에 따라 요구르트의 점도도 상승하여 0.5% 마늘 분말이 첨가된 요구르트의 점도가 가장 높았으며, 색도는 대조군과 마늘 분말 첨가 요구르트 사이에 유의적인 차이가 없었다. 관능적 특성을 조사한 결과 마늘 분말의 첨가에 따라 색은 더 높은 선호도를 보였고, 마늘 맛이나 향은 마늘 분말의 첨가량에 비례적으로 증가하였으며, 전반적인 기호도는 0.1%와 0.3% 첨가시는 대조군과 유의차가 없었다. 이상의 결과를 종합하여 볼 때 요구르트 고유의 품질특성이나 유산균의 생육 및 관능적 특성에 영향을 미치지 않는 범위에서 첨가 가능한 마늘 분말의 적정 수준은 0.3% 미만으로 판단된다.
