본 연구에서는 새싹종자 소독처리 여부에 따른 재배기간별 미생물 오염도 수준을 파악하고, 종자소독이 발아율에 미치는 영향을 분석하였다. 수입산 새싹종자 알팔파(alfalfa), 브로콜리(broccoli), 클로버(clover), 적양배추(red cabbage), 적무(red radish) 5종에 대하여 소독제 처리 여부에 따른 발아율과 재배기간별 미생물 분석을 실시하였다. 소독제 종류에 관계없이 새싹종자(알팔파, 클로버, 적무)는 48시간 후 90

This study investigated the microbial safeties and germination rates of five domestic sprout species(alfalfa, broccoli, clover, red cabbage, and red radish) grown from disinfected seeds. The 48 h germination rates of all seeds were over 90%, regardless of treatment. Seed total plate count(TPC) and coliform levels were reduced significantly(p for 15 min, following FDA recommendations. However, after germination, all sprouts regardless of treatment exhibited bacterial counts of . Listeria monocytogenes was detected at on germinated non-disinfected clover seeds at days 1, 2, and 5. In conclusion, although sprout germination from disinfected seeds potentially permits the growth of sprouts with lower pathogen counts, there were no significant differences in TPC or coliform levels between sprouts grown from disinfected seeds and control sprouts. Further work is needed to improve the microbial safety of cultivated sprouts and to find optimal conditions for seed germination.
