Abstract
Swollen commercially canned grapes and peaches were collected to investigate the microorganisms involved in their spoilage. 6 of 52 grape and 19 of 23 peach samples were found to be spoiled by microorganisms. Yeasts were the only spoilage microorganisms of canned grapes with Saccharomyces cerevisiae as the leading spoilage yeast. Yeasts and bacteria were found from spoiled canned peaches. S. cerevisiae and Torulopsis stellata were the most important spoilage yeasts of canned peaches. Lactic acid bacteria, belonging to genera of Lactobacillus and Leuconostoc, were the most frequently found spoilage bacteria. Only one spore-forming bacterium, Bacillus licheniformis, was involved in the spoilage of canned peaches.
팽창된 깐포도 및 복숭아 통조림을 시중에서 수거하여 부패현상을 검사한 결과 pH가 비교적 낮은 깐포도 통조림은 52개의 팽창관중 6개가 또 pH가 비교적 높은 복숭아 통조림은 23개 중 19개가 미생물에 의해 부패되었음을 알았다. 깐포도 통조림의 주요 부패 미생물은 Saccharomyces cerevisiae였고, 복숭아 통조림의 주요 부패 미생물은 S. cerevisiae 및 Torulopsis stellata로 밝혀졌다. 기타 Lactobacillus 및 Leuconostoc속의 젖산균도 흔히 발견되었으며, 포자형성세균으로는 Bacillus licheniformis가 한 개의 통조림에서 발견되었다.
