The purpose of this study was to develop a seasoned Hwangseoke-jeot(a kind of salted and fermented fish) with chitosan having less fishy smell and salty taste. In order to decrease the fishy smell and increase the palatable taste effectively, four types of seasoning were developed, in which minced ginger, garlic and onion were included. In order to improve the color and flavor of seasoned Hwangseoke-jeot, high-quality powdered hot red pepper was also added in all the seasonings. Seasoned Hwangseoke-jeot type 1 had the oil and roasted powder of sesame, which are known to decrease fishy smell and palatable taste, and was the basis of other seasoned Hwangseoke-jeot. Type 2 had the oil and roasted powder of perilla, which also were known to decrease fishy smell and to increase palatable taste effectively. Type 3 had roasted soybean powder and laver to increase savory and palatable taste. It was developed especially for old and young people who like savory taste. Type 4, containing citron syrup, was for the young and children. All the developed seasoned Hwangseoke-jeot samples had better red color and other sensory properies than the control (S-company's seasoned Hwangseoke-jeot), as tested by colorimetry and sensory evaluation. More than 1% (w/v) of chitosan gave an astringent taste to seasoning, so it is recommended not to exceed 1% (w/v) in the seasoning. The developed functional seasonings of jeot would be applicable to other kinds of jeot.

This study was carried out to investigate the properties of mul-kimchi made with allium victorialis. Chemical and sensory characteristics were determined during fermentation at $4^{\circ}C$ for 4 weeks. The pH decreased with an increase in total acidity. Mul-kinchi showed salinity properties ranging within $1.0{\sim}1.5%$ during fermentation. Hunter's color L, a-values were gradually decreased, but b-value was increased. In the texture, hardness and strength decreased as the aging time increased. The numbers of total- and lactic bacteria cells rapidly increased up to the second week, and this slowly increased thereafter. Sensory evaluation of mul-kinchi was favored for appearance, flavor, taste, texture and overall acceptability during the second week. Sensory properties of well ripened odor and sour taste negatively correlated with physicochemical properties of pH and hardness. Sour odor and sour taste were positively correlated with acidity and total- and lactic acid bacteria.

The evaluation of food taste is one of the important activities of human consciousness and it is practiced by sensory analysis using 5 terminal sensorial consciousness among many other functions. These consciousness activities may be conducted by 3 way branching transformation (3-WBT) logic, which choose one out of 3 options under the multi-layered consciousness decision making system. On the basis of this logic, cognitive sensory evaluation (CSE) method was developed to carry out questionnaire survey covering objective and subjective issues during consumption of food for pregnant women. The results of the CSE for several food items was presented with the Table-pattern called CSET covering consciousness factors and their effects on the food consumers.

The objective of this study was to investigate taste profiles and the correlation of Doenjang soup solution prepared with three different temperatures (5, 25, $45^{\circ}C$) and using an electronic nose (e-nose), electronic tongue (e-tongue), and descriptive analyses by trained panelists. A total of 17sensory attributes were generated from the descriptive analyses for the Doenjang soup solution. There were significant difference among the samples in the cooked soybean flavor, the cooked soybean odor, the soy sauce odor, the sweet odor, the sweet taste, and the sweet aftertaste attributes. The intensities of these sensory attributes tended to increase as the serving temperature of the Doenjang soup solution increased. There were seven volatile compounds detected by the electronic nose: ethanol, propanal, 2-methylpropanal, ethyl acetate, 3-methylbutanal, and beta-pinene. The intensities of the volatile compounds increased as the temperature of the Doenjang soup solution increased. On the other hand, the intensities of the basic tastes by the e-tongue decreased as the temperature of the Doenjang soup solution increased. In conclusion, the e-nose, e-tongue, and descriptive analysis results showed different correlations depending on the temperature of the Doenjang soup solutions.

This study was carried out to examine the sensory characteristics of Demi-glace sauce prepared by fresh basil with different amount of salt added. The evaluation of the sensory quality of Demi-glace sauce prepared by fresh basil was conducted by unexperienced and trained panel with regard to color, odor, taste, appearance, texture, viscosity, and overall acceptability while varying the quantity of salt added, the time of preparation, and the conditions of sauce offered in which each panel was supposed to evaluate both sauce itself and sauce with meat. It was found that Demi-glace sauce prepared by fresh basil with 0.3% salt added was gained the highest score from both panels in most properties and the second was the one with 0.1% salt added. In the sensory properties correlation analysis according to the time of preparation and the conditions of sauce offered, there was no significant correlation in most sensory properties for the unexperienced panel, except some significantly positive correlation between taste and overall acceptability of the sauce. Whereas there was a positive correlation in the majority of sensory properties for the trained panel regardless of the time of preparation and the conditions of sauce offered. The sauce with 0.3% salt added ranked as the best recipe by both panels among four different ratios of salt adding regardless of the time of preparation and the conditions of sauce offered. Triangle test showed that the sauce B with 0.1% salt added before the preparation was more highly appreciated in terms of taste than the sauce A with 0.1% salt added in the final step of preparation. In conclusion, it could be suggested that Demi-glace sauce prepared by fresh basil with 0.3% salt added is the best recipe for commercial products. Also, there seems to be the need of further sensory evaluation studies on the Demi-glace sauce according to the time of addition during the process of preparation.

In this study, manufactured a cream soup by varying addition of Hericium erinaceus and decided its recipe, and conducted particle size analysis, calorimetry, sensory test for investigating physicochemical characteristics and quality characteristics (salinity, sugar content, color value, pH, viscosity), antioxidant activities of soup, and mechanical sensory test for objectivity. This study found that moisture content in Hericium erinaceus powder was 6.16%, crude protein 26.87%, crude fat 4.62% and crude ash was 10.75% respectively. No significant differences were found in salinity, sugar content, pH according to addition of Hericium erinaceus. As for color value of cream soup manufactured by adding Hericium erinaceus, L value decreased with increase in addition of Hericium erinaceus, whereas a value and b value increased. The more the addition of Hericium erinaceus, the higher the viscosity, which increases concentration of soup. As result of analysis on antioxidant activities of Hericium erinaceus cream soup, antioxidant activities increased with increase in addition of Hericium erinaceus. Particle size analysis showed results similar to that of viscometry, which means that the smaller the particle size, the higher the viscosity, whereas viscosity lowered vice versa. Calorie of cream soup showed no significant difference notwithstanding the amount of addition. As a result of sensory test, S5 with 5% of Hericium erinaceus powder was highest rated in color, flavor, taste, umami taste and overall preference. As a result of mechanical sensory test, umami taste increased with increase in addition of Hericium erinaceus powder, whereas bitterness taste lowered significantly (p<0.05) with addition of Hericium erinaceus. As for salty taste, both control group and experimental group that added Hericium erinaceus powder showed no significant difference. Accordingly, experimental group with 5% of Hericium erinaceus powder was proved to be the most desirable.
