In this study, the preparation characteristics of cream cheese added mousse cake which can easily be accessible among the mousse cakes, have drawn a lot of attention from the modern people, However, there have been a lack of studies that focused on the manufacturing of the mousse cake with a various added proportion rates of main ingredients, fresh cream in mousse cake by 0%, 25%, 35%, 45%, and 55%. While the sugar concentration has increased, except for the control group, there is no significant difference. In case of chromaticity, it has shown high level at L values. In addition, values have shown bigger values as increasing the added amount, and b values have shown smaller values as increasing the added amount. For moisture content, it has shown as steadily increasing by heightening the added amount of cream cheese. For texture, CM3 added by 35% in all the items, except for hardness, has shown the best result and CM3 added by all 35% in all the items, has also been evaluated as highest. Based on all the results, it can be concluded that the addition of cream cheese by 35% to fresh cream is most appropriate, on manufacturing the cream cheese mousse cake.

Salmonella spp. are frequently associated with food and are among the most important foodborne pathogens. The recent Salmonella out breaks in Korea was associated with chocolate mousse cakes served with school meals during September 2018. The objective of this research was to compare the 3M Molecular Detection Assay 2 - Salmonella and the Korean Standard Method of Salmonella in artificially inoculated mousse (chocolate and cheese) and tiramisu cakes. Mousse (chocolate and cheese) and tiramisu cakes were artificially inoculated with S. Typhimurium. Twenty five gram of sample was enriched with 225 mL buffered peptone water for incubation at $37^{\circ}C$ for 24 h. After enrichment, the cultures were analyzed by using the 3M Molecular Detection Assay 2 - Salmonella and the Korean Standard Method. Most of the inoculated samples showed similar results except the chocolate mousse cakes, in which real-time PCR was unable to detect S. Typhimurium even after $10^4CFU/25g$ of inoculation. However, S. Typhimurium inoculated at a concentration of $10^0CFU/25g$ was detected by using 3M Molecular Detection Assay 2 - Salmonella. In chocolate mousse, detection of S. Typhimurium using real-time PCR was partially successful when dark chocolate was added at less than 15%. Negative results in real-time PCR and 3M Molecular Detection Assay 2 - Salmonella were confirmed by gel electrophoresis. The data indicated that dark chocolate could inhibit amplification of the target gene in the PCR reactions. In conclusion, the 3M Molecular Detection Assay 2 - Salmonella was better than the Korean Standard Method (real-time PCR) for the detection of S. Typhimurium in chocolate mousse cakes and chocolate mousse.
