Effects of Dasom Valley and Bora Valley on fecal microflora, fecal moisture, and fecal pH of twelve healthy human volunteers were investigated. Numbers of Bifidobacterium, Clostridium perfringens, Escherichia coli, and Lactobacillus of control group were $9.24{\pm}0.63$, $4.44{\pm}1.21$, $7.75{\pm}0.38$, and $6.98{\pm}0.81$ (Log CFU/g wet feces), respectively. During administration of Dasom Valley, numbers of Bifidobacterium and Lactobacillus were $10.70{\pm}0.44$ and $8.84{\pm}0.77$, whereas those of C. perfringens and E. coli were $2.96{\pm}1.50$ and $6.69{\pm}0.29$, respectively. Administration of Dasom Valley significantly increased growth responses of beneficial bacteria, Bifidobacterium and Lactobacillus, whereas those of harmful bacteria, C. perfringens and E. coli, significantly decreased. Moisture content of feces increased and fecal pH decreased with intake of Dasom Valley. Intake of Bora Valley slightly increased numbers of Bifidbacterium and Lactobacillus and slightly decreased those of C. perfringens and E. coli. Results indicate Dasom Valley has greater intestinal-modulating effect than Bora Valley and Atlantic. Daily intake of Dasom Valley may normalize disturbed physiological functions, resulting in improvement of growth and composition of microbial community within intestinal tract.

본 연구는 기능성 식품 소재용 감자 계통을 선발하고자, 35개의 계통 및 대조구 품종인 '수미', '다솜밸리' '고구밸리'의 총 폴리페놀, 총 안토시아닌, 비타민C의 함량을 분석하였다. 분석결과, 계통별 함량차이가 큰 것으로 나타났으며, 그 가운데서 총 폴리페놀 함량은 KPG16 계통이 $105.08mg{\cdot}100g^{-1}\;FW$, 총 안토시아닌 함량은 KPG13 계통이 $4.78mg{\cdot}100g^{-1}\;FW$, 비타민 C 함량은 KPG20 계통이 $22.16mg{\cdot}100g^{-1}\;FW$으로 각각 높게 나타났다. 종합적으로 분석한 결과, KPG5계통이 총 폴리페놀, 총 안토시아닌, 비타민 C 함량이 각각 103.95, 3.15, $12.12mg{\cdot}100g^{-1}\;FW$ 으로 3성분을 고루 함유하고 있음을 확인할 수 있었으며, 추후 기능성 품종 선발의 소재로 활용될 수 있을 것으로 사료된다.
