영어 초록

Rice has been the most important staple food in everyday meals of Korean people for thousands of years. Nowadays, it is getting increasingly used as flour ingredients in a variety of processed foods, so that it is consumed in more diversified ways. As a consequence, production volume of rice flour to manufacture rice cakes, noodles,breads, or confectioneries is recently getting increased in Korea. But there are not sufficient research outcomes to guarantee Korean consumers microbiological qualities of rice flour as well as rice. As a preliminary experiment,therefore, the microbiological profiles (aerobic mesophilic bacteria (AMB), spore-forming aerobic bacteria (SAB),lactic acid bacteria (LAB), yeasts and molds (YM), and Escherichia coli and coliforms) have been monitored for nine retailed white rice samples in this study. AMB counts ranged 10² - 10^6CFU/g for all the nine white rice samples. All the nine rice samples have SAB counts within a narrow range (1.0 × 10²- 2.5 × 10³CFU/g). LAB was detected in two white rice samples (4.0 × 10² and 3.7 × 10³ CFU/g). YM was detected in one white rice sample (2.0 × 10² CFU/g)only. E. coli was not detected from all the nine samples. Coliforms were detected in one white rice sample (4.1 × 10CFU/g) only. All the rice samples were conclusively considered to have various microorganisms, though most of them are harmless and some, such as coliforms, may be harmful.
