- Abstract
- Eoyukjang is a special Korean soy paste mixed with various meats and fishes, increasing their nutritional value andadding specific flavor, and taste. ε-poly-L-lysine mixtures (EPM) 1.48%, Lactobacillus halophilus 0.5%, and red ginsengpowder (RGP) 0.5% were added and stored at 25oC for 12 wk. The pH, viable cell count, DPPH radical scavengingactivity, viscosity, pathogenic microorganisms, and sensory evaluation were measured during the storageperiods. EPM did not influence the DPPH radical scavenging activity. However, the addition of EPM inhibited thegrowth of microorganisms and increased the shelf life. On the other hand, L. halophilus showed higher DPPH radicalscavenging activity as well as enhanced shelf life. In the case of RGP, DPPH radical scavenging activity wassimilar to that of L. halophilus, whereas the sensory scores were highly estimated. Pathogenic microorganisms, suchas Vibrio parahaemolyticus, Bacillus cereus, and Escherichia coli O157:H7, were not detected, and Eoyukjang wassafe during the 12 wk storage period.
