The chemical composition of essential oils obtained from aerial parts in spearmint, apple mint and chocolate mint, was investigated by gas chromatography/mass spectrometry analyses. (-)-Carvone (33.0%) was quantitatively major compound in spearmint, followed by R-(+)-limonene (11.7%) and ${\beta}$-phellandrene (9.7%); (-)-carvone (37.4%) and germacrene D (11.9%) in apple mint; and (-)-menthol (34.3%), p-menthone (18.4%) and menthofuran (9.8%) in chocolate mint. Hierarchical cluster analysis and principle components analysis showed the clear difference in chemical composition of the three mint oils.

The purpose of this study was to investigate the effects of oriental medicinal plant extracts added to chocolates on the moisture content, color, radical scavenging activity and sensory characteristics. The oriental medicinal plant extracts were added at a weight percentage of 0, 4 and 8%. As the ratio of the extracts in the chocolates increased, the moisture content, color, and radical scavenging activity increased. In sensory evaluation, significant differences (p<0.05) were shown in taste, bitterness, and overall acceptability depending on the addition of oriental medicinal plant extracts but there were no significant differences in chocolate aroma and texture.

This study was conducted to investigate the general utilization and preference for the western desserts from confectioneries and hotels by the female university students in Seoul and Kyunggi area. The most high frequency of utilizing western desserts from confectioneries was 1∼3 times a month. Five items of confectionary dessert (chocolate, jelly, candy, cookie and ice cream) were preferred by house-dwellers and non-food science majors. And the families with higher income favoured chocolate and pie. The purchasing frequency of western desserts from confectionery was far more frequent in jelly and candy(1∼3 times a week) compared with chocolate, pies and cookies(1∼3 times a month) and sherbet and ice cream(1∼4 times a year). Hotel was used less frequently for purchasing western desserts. Cake was recognized well as a western dessert by the house-dwellers, and ice cream was recognized better by the apartment-dwellers (p＜0.05). And the respondents with food science major had a wider preference for cake, pudding and ice cream(p<0.05).

Development of chocolate products to improve the quality and functional properties with Bifidobacterium-fermented isoflavone powder (BFIP) was attempted. Effects of BFIP on sensory value, isoflavone contents, and microbiological characteristics of chocolate products during storage at room temperature $(24{\pm}0.5^{\circ})$ for 90 day were studied. Five different BFIP concentrations of 0, 1, 2, 3, and 4% (w/w) were added and blended into the chocolate products. Results of sensory evaluation showed that the scores for softness and bitter taste decreased as the BFIP contents increased. In sweet and sour taste, the highest score was shown at 1% BFIP treatment. In overall acceptability, 1% treatment was the most favored, followed by 2% treatment. Contents of isoflavone in chocolate products were stably maintained during 90 storage days. The viable cell numbers of Bifidobacterium remained relatively stable until 70 day, followed by a slow decrease thereafter in all treatments.

The flavor of food is not decided by only the sense of taste. Flavor is a complex ,ionization involving taste and aroma. It is also affected by the appearance, color and shape and touch or texture of food. Although our all senses are crucial factors in recognizing the sense of food, the sense of vision, especially colors, is a more crucial aspect. Because when consumers contact food, first of all, they see and recognize the color of the food and associate the flavor of the food as the colors of the food. This study focuses on the ways for applying colors to food so that consumers can associate the flavor of food efficiently. This study conducts a case study using web survey about the association of flavor by chocolate's colors. The result of the case study shows crucial factors influencing the association of food and color palettes according to sorts and degrees of chocolate's taste.

The rheological properties of sugar and cocoa particle suspensions in cocoa butter under molten condition were analyzed with Haake rotationary viscometer. Both suspensions had yield value and showed rheopexy at low shear rate and thixotropy at high shear rate. Flow behaviors of the suspensions were analyzed with modified Casson model. Casson viscosity and yield value increased with increasing the concentration of sugar and cocoa particles. There was an obvious dependence of the Casson viscosity and yield value on the particle size distributions that was represented by the Sauter mean diameter of the particles. Casson viscosity and yield value of cocoa butter-sugar suspension increased with increasing the fineness of sugar particle crystal. With increasing the fineness of cocoa particle a decreasing Casson viscosity of cocoa butter-cocoa particle suspension was achieved, but the yield value did not change significantly with cocoa particle size. Therefore, it was predicted that the best rheological properties of chocolate could be obtained with the combination of coarse ground sugar $(d=36.30{\mu}m)$ and fine ground cocoa particle $(d=14.81{\mu}m)$ within the studied range.
