Abstract

Ice cream was prepared from cream added egg white mix(EWM) food fermented with Lactobacillus acidophilus(KCTC 2182). Change of viable cells during fermentation of cream added EWM food and sensory properties and hardness of ice cream prepared from lactic fermented EWM food added with cream were investigated. (1) As the ratio of cream to EWM was higher, stationary phase of growth curve of L. acidophilus was longer and number of viable cells during fermentation was higher. (2) Sensory properties of ice cream prepared from Formula 4 (EWM 60 : cream 40) and Formula 5 (EWM 50 : cream 50) were better than those of other formulas. Optimum condition of mix formula and fermentation time was Formula 4 fermented for 15 hr. (3) As the ratio of cream to EWM was higher, the hardness value of ice cream was lower. Therefore, the hardness value of ice cream prepared from Formula 5 was the lowest.

본 연구에서는 크림이 첨가된 난백젖산균발효식품에서 Lactobacillus acidophilus(KCTC 2182)생균수의 경시적인 변화, 크림 첨가 난백젖산균발효식품으로 만든 아이스크림의 관능적인 특성과 경도를 조사하여 다음과 같은 결과를 얻었다. (1) 크림의 첨가비율이 높을수록 젖산균 생육곡선의 stationary phase가 연장되고, 발효시간별 생균수도 높은 경향을 나타냈다. (2) Formula 4(크림 첨가비율 40%)와 Formula 5(크림 첨가비율 50%)로 만든 아이스크림의 관능적 특성이 다른 시료보다 우수하였으며, Formula 4의 15시간 발효시료가 아이스크림 제조원료로서 적합하였다. (3) 경도의 측정 결과를 보면 크림의 첨가비율이 증가할수록 경도가 감소하여 Formula 5의 경도가 가장 낮았다.
