Leuconostoc mesenteroides와 Lactobacillus brevis, Lactobacillus fermentum을 무주스에 starter로 0.3%(106 cfu/)첨가하여 에서 7일, 15에서 20일, 5에서 36일동안 숙성하면서 단독, 또는 혼합 배양에 의한 무주스의 가공특성을 조사하였다. 무주스를 에서 숙성할 경우 유산균수는 혼합배양이 단독배양보다 높게 계수 되었으나 낮은 온도 (15~5)에서는 접종균주에 따라 증감의 차

The starters, 0.3% of Leuconostoc mesenteroides, Lactobacillus brevis and Lactobacillus fermentum, were added in radish juice to process the radish juice by single and mixed cultures. The radish Juice was fermented for 7 days at 25, 20 days at 15, and 36 days at 5. When fermented at 25, the number of lactic acid bacteria in the juice made with mixed culture was higher than that of the single culture. But, juice fermented at low temperatures (15∼5), the addition of starters was not effective, although there were some differences by inoculation strains. Although there was a little differences by inoculation strains, the content of nonvolatile organic acid and L-ascorbic acid were found more in the juice inoculated with lactic acid bacteria than the juice not inoculated. When the single and mixed cultures at the optimal maturity were tested, the significant difference was found at 5% level except the yeasty and moldy smell and the unripe taste. According to the preference test, the mixed-cultured radish juice incubated at 25with Lactobacillus brevis and Leuconostoc mesenteroides were evaluated superior to commercial Dongchimi. As a result, taste and quality of radish juice was improved by addition of starters.
