본 연구에서는 고춧가루의 오염된 미생물을 제거 또는 소시키기 위해 감마선조사를 하였고 이를 이용하여 콩나물 무침을 제조 한 후 저장 중 미생물학적 안전성과 품질 성을 평가하고자 하였다. 콩나물 무침용 원재료의 총세균수 평가 결과 고춧가루와 마늘의 경우 5.72와 2.40 log CFU/g 수준인 것으로 나타났으며 다른 재료에서는 검출한계 이하였다. 대장균군과 곰팡이/효모의 경우 고춧가루에서만 각각 3.11, 3.48 log CFU/g 수준으로 나
This study investigated the microbiological and sensory characteristics of Kongnamul muchim stored with gamma-irradiated red pepper powder at . Total aerobic microbes in raw Kongnamul muchim were 5.72 log CFU/g in the red pepper powder and 2.40 log CFU/g in the garlic used during storage, but were not detected n other raw materials. Coliform bacteria and fungi were found, at 3.11 and 3.48 log CFU/g respectively, only n the red pepper powder. Microorganisms in Kongnamul muchim stored with gamma-irradiated (10 kGy) red pepper owder were not detected over 3 days of storage at . The pH, Hunter's color value, and sensory characteristics id not change significantly on storage. These results suggest that the addition of gamma-irradiated (less than 10 Gy) red pepper powder could improve the microbiological safety of Kongnamul muchim without changing desirable ensory characteristics.
