Food materials for kimchi manufacturing were treated by ozone or gamme irradiation to reduce the number of contaminated microorganisms before the manufacturing of kimchi. Counts of total aerobic bacteria, yeast and mold were 10∨6~10∨ 7 and 10³~10⁴CFU/g in the food materials, respectively, in a dose-dependent manner. In comparison, gamma irradiatio was superior to ozone treatment. Especially, irradiation of 5 kGy fully eliminated the yeast and mold attached in the food materials for kimchi manufacturing.
