Abstract

The purpose of this study was to improve the quality characteristics of soy ice cream supplemented with oligosaccharide, and to test its blood glucose lowering effect. Boiled soybean powder was compared to parched soybean powder and to milk, as an ingredient. The soybean powder base was prepared by incubating with fructooligosaccharide (FOS) and apple juice, along with Lactobacillus acidophilus and L. bulgaricus at $30-40^{circ}C$ for 24 hr. With the fermentation process, the fishy smell of the soybean was removed and the taste improved. The overrun and melt-down values of the boiled soybean ice cream were significantly higher than those of the parched soybean ice cream, although they were significantly lower than those of the milk ice cream. The sensory characteristics of the soy ice cream prepared with the fermented base of boiled soybeans were significantly improved, as compared to those of the ice cream made using parched soybeans, but they were not significantly different from those of the milk ice cream. The blood glucose level at 120 min after ingestion of the ice cream prepared with FOS and the fermented base of boiled soybean powder was significantly lower than that occurring with the milk ice cream made with sugar.

본 연구는 콩 아이스크림의 품질향상을 위하여 콩을 데치고 동결 건조 한 후 분말화하여 과즙을 첨가하고 혼합 유산균 종균을 배양시켜 대두분말 발효 베이스를 제조한 후 올리고당을 첨가하여 식감개선, 저칼로리 및 혈당 수준의 개선 특성을 가진 콩 아이스크림을 제조하여 그 품질 특성과 혈당개선능을 비교하였다. 대두분말을 $121^{\circ}C$에서 15분간 가압멸균한 후 $30^{\circ}C$로 냉각한 다음, L. acidophillus KTCT 3164와 L. bulgaricus KCTC 3635 현탁액을 $4.6}{\times}106$ CFU/mL의 농도를 1:1 비율로 혼합한 균주(1%)를 접종하고 $33^{\circ}C$에서 24시간 발효시킨 후 비교한 결과, 삶은 대두분말 발효베이스가 볶은 대두분말 발효 베이스에 비해 pH는높았고 점도는 낮았다. 생균수는 접종 후 24시간 배양 후 삶은 대두분말 발효 베이스의 유산균 생육이 우세하였다. 관능검사법으로 평가한 대두분말 발효베이스의 종합적인 기호도는 삶은 대두분말 발효베이스가 콩 특유의 비린 맛과 냄새가 약하면서 상큼한 풍미가 많고 입안의 질감이 부드러워서 관능적인 품질이 양호한 것으로 나타났다.볶은 대두분말 베이스 아이스크림이 overrun과 녹아내리는 정도가 가장 낮았고, 이에 비해 삶은 대두분말 발효베이스 아이스크림은 overrun과 녹아내리는 정도가 증가하여 품질 특성이 현저하게 향상되었다. 냉동에 의한 생균수의 변화는 삶은 대두분말 발효베이스 아이스크림군이 볶은 대두분말 발효베이스 아이스크림군보다 높게 나타났으나, 같은 아이스크림 군 간에는 냉동에의한 생균수의 유의적인 차이는 없었다. 관능검사에 의한 아이스크림의 텍스쳐는 우유아이스크림이 가장 높게 평가되었으나 삶은 대두분말 발효베이스 아이스크림과 유의한 차이는 없었다. 종합적인 기호도는, 우유 아이스크림과 유의한 차이는 보이지 않았음에도 불구하고, 삶은 대두분말 발효베이스 아이스크림이 가장 양호하게 평가되었다. 건강한 20대 여성들을 대상으로 아이스크림의 경구 혈당반응 검사 결과, 설탕 첨가 우유 아이스크림과 올리고당 첨가 삶은 대두분말 발효베이스 아이스크림 사이에 혈당 면적은 유의한 차이가 없었으나, 아이스크림 섭취 후 120분 혈당은 올리고당 첨가 삶은 대두분말 발효베이스 아이스크림을 먹은 경우가 설탕 첨가 우유 아이스크림을 먹은 경우에 비해 유의하게 낮았다. 또한 혈당 증가가 완만하여 식사 후 혈당관리가 중요한 당뇨환자에게는 일반 아이스크림보다 유익할 것으로 사료된다.
