Abstract

The viable cell of 60% drinking water among 25 drinking water served in restaurant of Daegu district showed above 100 CFU/mL which is sanitary standard of drinking water. The 50 CEO of restaurant considered drinking water served in their own restaurant as just safe and were very deficient in aware of sanitation about drinking water. Sensory quality of drinking water boiled with plant materials, such as barley, Cassia semen, corn, Buckwheat, Korean solomon's seal, Chamomile, Brown rice-green and peppermint was improved in color, taste, flavor and overall acceptability compare to marketed drinking water, respectively. Especially drinking water boiled with Korean solomon's seal was the best In overall acceptability. The number of total bacteria reached above $10^2 CFU/mL$ in marketed drinking water after 4 days storage at 10. But the growth of microorganism did not occur in boiled drinking water with Brown rice-green tea, Korean solomon's seal, barley, Cassia semen and com during storage for 10 days at $10^{\circ}C$, respectively. The number of total bacteria reached above $10^2 CFU/mL$ in marketed drinking water after storage for 1 days at $25^{\circ}C$. The growth of microorganism was accelerated in boiled drinking water with corn, Korean solomon's seal, barley, Cassia semen except Brown rice-green tea during storage far 10 days at $25^{\circ}C$, respectively.

대구근교 외식업체 25곳의 고객에게 제공되고 있는 음용수의 위생실태를 조사한 결과 약 60%가 총균수의 허용한도는 100 CFU/mL를 초과하였으며, 외식업체를 경영하는 CEO 50명을 대상으로 음용수에 관한 설문조사를 한 결과 음용수에 대한 위생의식은 매우 부족하였다. 보리차, 결명차, 옥수수, 메밀, 둥굴레, 캐모마일, 현미녹차, 페파민트를 사용하여 제조한 음용수의 색, 맛, 향, 종합적기호도는 생수에 비해 전반적으로 기호성이 증가하였으며, 종합적 기호도는 둥굴레차가 가장 좋았으며, 옥수수차, 결명자 차, 보리차 순으로 양호하였다. 시판 현미녹차, 둥굴레차, 보리차, 결명차, 옥수수차를 이용하여 음용수를 제조하여 플라스틱 물병에 분주하여 $10^{\circ}C$와 $25^{\circ}C$에 저장하면서 총균수의 변화를 검토한 결과 $10^{\circ}C$에서 대조구는 저장 4일 이후 $10^2 CFU/mL$이상을 나타내어 음용수로서 부적절하였으며, 현미녹차, 둥굴레차, 결명차, 옥수수차는 저장기간 동안 미생물의 증가 현상이 거의 나타나지 않았다. $25^{\circ}C$에 저장한 경우 대조구는 저장 2일 이후 $10^2 CFU/mL$이상을 나타내었으며. 옥수수차, 둥굴레차, 보리차, 결명차에서 오히려 미생물의 성장이 촉진되는 현상을 나타내었으나, 현미녹차의 경우 전 저장기간 동안 생균수의 증가현상은 나타나지 않았다.
