  • This study was conducted to investigate effect of mungbean sprout and soybean sprout against the growth of spoilage microorganism (Bacillus subtilis, Bacillus cereus, Pseudomonas fluorescens, and Listeria monocytogenes). After blanching at different conditions, the viable cells of the spoilage microorganisms were increased with storage time, but the viable cells were almost same after treating with either mungbean sprout or soybean sprout. The viable cell population in minimal broth treated with filtrate of mungbean sprout was higher than that of soybean sprout after 24 hr. However, the growth of spoilage microorganism in filtrate of mungbean sprout and soybean sprout was depending upon strain type. During incubation for 72 hr at $25^{\circ}C$, the color change of mungbean sprout was appeared moderately, but in soybean sprout it was appeared clearly at 24 hr. These results indicate that the effect of mungbean sprout and soybean sprout against growth of spoilage microorganism was not different.
