This research aims to investigate pudding with grain-added yogurt for its quality characteristics and viability during cold storage. The yogurt was fermented until its pH was 5.10±0.05 after inoculating the probiotic strain (Bifidobacterium lactis, BB-12) into the milk base containing grains. The yogurt was added to prepare probiotic puddings. During cold storage of the puddings at 4±1oC for 4 week, the quality characteristics (pH, acidity, texture) and the viability of BB-12 in pudding were determined and compared to control (only milk base). As a result, MR had a significantly lower pH and higher acidity than those of other samples. In texture properties, including hardness, gumminess, and chewiness, MSIR showed the significantly highest value, and the pudding with inulin was significantly higher than rice flour in all textures. For the viability of BB-12, pudding with milk was significantly lower than pudding containing milk and soymilk, suggesting that soymilk helps maintain viability. MR showed significantly higher viability than MI in the milk-based pudding, indicating that rice flour is more effective than inulin. Therefore, the addition of soymilk, inulin, and rice can maintain quality characteristics and viability of BB-12 in the pudding.

이상의 결과를 종합하면, 혼합유산균 2종(Bifidobacterium animalis ssp. Lactis Bf141와 Lactobacillus rhamnosus Lb102)의 섭취는 고지방식이 유도 비만 마우스에서 체중, 체지방, 제지방, 골밀도 등 주요 체성분에 영향을 주지 않았다. 혼합유산균은 식욕 조절 효과를 위해 측정한 사료 섭취량에도 영향을 주지 않았으며, 간 조직 무게에도 영향을 미치지 않았다. 인슐린저항성과 포도당신생합성의 주요 지표인 공복혈당량 또한 혼합유산균 급여에 의해 변화 하지 않았다. 또한 혼합유산균은 심혈관질환의 지표로 사용되는 혈중 중성지방 및 총 콜레스테롤에 영향을 주지 않았으며, 체내 지방의 소화 및 흡수율에서도 영향을 미치지 않았다. 결론적으로, 고지방식이유도 비만 마우스를 이용하여 혼합유산균(Bf141 + Lb102)의 항비만 생리활성 을 검증한 결과, 유의미한 물리적, 대사적 표현형 개선은 검증되지 않았다. 따라서, 추후 개별 보다 다양한 혼합 조건 및 농도로 연구를 설계하여 혼합유산균의 항비만 효과를 검증할 필요성이 있다.
