The aim of this study was to develop rice cookies based on 'Goami 2' rice, and made with sesame (white and black) and perilla seeds. Furthermore, we studied the physicochemical and sensory characteristics of the cookies as well as the alternative effects of the sesames or perilla seeds for butter, where we substituted the sesames or perilla for 30% of the total butter. The pH values of the cookie doughs made with the sesames or perilla seeds were significantly different (p<0.001), whereas the spread factors of the doughs were not significantly different. The Hunter color L-, a-, and b- values were significantly different for the cookies made with the added sesames or perilla seeds (p<0.001). The brittleness of the Goami 2 rice cookies (control) was significantly higher than that of the cookies made with the sesames or perilla (p<0.001). In a descriptive analysis performed by 8 trained panelists, the following sensory characteristics: yellow, black, sweet taste, nutty taste, nutty odor, oily flavor, and off flavor, were significantly different among the cookie samples. In a consumer test by 50 women students, the Goami 2 rice cookies were preferred in the following order: Goami 2 rice cookies with no additions > black sesame cookies > white sesame cookies > perilla cookies. In conclusion, some physicochemical and sensory characteristics of the cookies were different, in relation to being made with or without the sesame or perilla seeds. However, because of the small difference in acceptance among the cookies, the sesame and perilla rice cookies show strong potentials for consumer acceptance. Moreover, the black sesame cookies were more acceptable in terms of butter substitution for the cookie preparation.

Doenjang made with various concentrations of salt solution such as 13, 14, 15, 16, 17, and 18% for making low-salt Doenjang. Physicochemical and sensory characteristics of Doenjang made with various concentrations of salt solution were analyzed. As a result, salt contents of Doenjang made with various concentrations of salt solution were 6.09~13.47%. Amino-type nitrogen showed a higher value when prepared with lower salt solution. The pH value increased with lower concentration of salt solution, whereas total acidity decreased with lower concentration of salt solution. The pH values and total acidity of Doenjang made with more than 16% salt solution were not statistically different. The reducing sugar content ranged from 1.39~6.30 mg/g, and higher salt content was associated with higher reducing sugar content. In the sensory descriptive analysis, Doenjang had the most salty taste at a salt concentration of 18%, whereas Doenjang at concentrations of 15%, 16%, and 17% did not show any statistical differences. In the consumer acceptance test, Doenjang made with 17% and 18% salt solution showed the highest score, followed by Doenjang made with 15% and 16% salt solution. In conclusion, the salty taste of Doenjang made with 16% salt solution might be used to make low-salt Doenjang. However, consumer acceptance of these Doenjangs was lower than that of Doenjang made with 17% and 18% salt solution.

Sensory comparison of the flavor of ginseng teas prepared from concentrated white or red ginseng extract was investigated by multipl comparison test and quantitative descriptive analysis (QDA) on 12 selected descriptions. The white ginseng tea revealed higher intensities in odor and taste than those of red ginseng tea, particularly on earthy and sweet odor and bitter and astringent taste. Increase in sample temperature from $2^{\circ}C$ to $80^{\circ}C$ caused a general increase in aroma and bitter taste. When sucrose added into 3% ginseng tea solution, all of the taste descriptions, most significantly on bitterness and astringency, scored lower except sweetness while the aroma was affected a little.

We sought to extend the shelf-life of Alaska pollack Theragra chalcogramma sikhae while maintaining quality. We compared the chemical, microbiological, and organoleptic characteristics of sikhae prepared under four different conditions. Control fish were fermented at ambient temperature ($21{\pm}2^{\circ}C$); other samples were stored at $5^{\circ}C$ after fermentation at ambient temperature for 36 h (A1), 60 h (A2), and 84 h (A3). Volatile basic nitrogen and amino-nitrogen levels, and total acidity increased with fermentation time in all samples, but the pH fell, attaining a relatively lower level in the control than in other samples. Over 90% of all viable cells were lactic acid-producing bacteria; this proportion did not change significantly during fermentation. In terms of texture, only hardness was affected by fermentation. The hardness of the control fell more rapidly than did that of the other samples. In terms of sensory evaluation (the acceptance test and quantitative descriptive analysis [QDA]), A2 was superior to other samples after fermentation for different times; A2 maintained limited salability (6 points on the relevant index) for up to 17 days of storage.

The purpose of this study was to determine the best cooking condition for salted-dried flathead by sensory evaluation. Raw flathead and 3 different kinds of salted(2%, 4%, 6%)-dried flathead were cooked by various methods such as steaming, boiling, baking and different cooking times(5, 10, and 15min). The results of this study were as follows: 1. In steamed samples, the meaty flavor was significantly related with brown color, cooled level, and softness at 5% level. 2. In boiled samples, meaty flavor was significantly related with cooked level, moistness, and fishy odor at 5% level. 3. For broiled samples, meaty flavor was significantly related with fishy odor, meaty aroma, and bitter taste at 1% level. 4. The best cooking conditions determined by a quantitative descriptive analysis(QDA) were steaming 6% salted-dried samples for 5min, and boiling or broiling 6% salted-dried samples for 10min. The most favored cooking method was broiling. 5. In comparison of the samples by QDA, 2% salted-dried samples cooked 15 min gave better scores in the order of boiled > overall score > steamed > broiled, 4% samples cooked 5min were boiled > steamed > overall score > broiled, and 6% samples showed similar scores among all conditions. The 6% samples cooked for 5min gave high scores in 7 terms of QDA in steaming, and 6% samples cooked for 10min for boiled and baked.

The chemical components of chlorella powder and quality characteristics (texture, color and sensory evaluation etc.) of white bread added with chlorella powder in order to use as a new functional food material of chlorella powder were examined. The proximate composition was composed of crude protein 61.45%, crude fiber 13.47%, nitrogen free extract 13.15%, ash 6.35%, moisture 3.27% and crude fat 2.31%, respectively. The component of major minerals were P (1,478.94 mg%), K (250.54 mg%), Ca (147.24 mg%) and Na (107.26 mg%) and free sugar was composed of maltose 0.12%, glucose 0.09% and fructose 0.08%. The major amino acids of chlorella powder were glutamic acid(4,009.20 mg%), aspartic acid(3,017.72 mg%), proline(3,055.24 mg%), methionine(3,001.52 mg%) and histidine(2,951.06 mg%). The major fatty acids in chlorella powder were composed of linoleic acid and the amounts of those showed 34.27%. The volume tended to increase according to the addition of chlorella powder. Substituting chlorella powder with flour also resulted in decreased lightness, redness and yellowness of the white bread crust The color of white bread crust became darker as the amount of chlorella powder increased. The texture characteristics of white bread containing chlorella powder was no significant difference. The result of sensory evaluation by QDA (quantitative descriptive analysis) showed that overall acceptability of white broads containing 0.2% chlorella powder were higher than that of control without chlorella powder.

This study investigated the relative sweetness of various sweeteners (tagatose, xylose, erythritol, sucralose, and enzyme treated stevia) in milk and instant coffee systems. Additionally, the effects of interactions with other ingredients on the sensory characteristics of milk and coffee were explored. In the case of a banana-flavored milk system, sucrose was added to a concentration of 5%, and the five types of sweetener were added to a concentration of equal sweetness to a 5% concentration of sucrose. For coffee systems, 5.9% sucrose level and sweeteners' concentration equivalent to this level was added. A generic descriptive analysis was performed using ten trained panelists. The results showed that the relative sweetness of all the sweeteners was identical to that identified in the aqueous system, except for stevia in the milk system and in the coffee system with added vegetable cream. For the black coffee system, the relative sweetness decreased for tagatose, erythritol and for stevia. Fat and vegetable cream significantly affected the sensory qualities of milk and coffee, respectively.

This study investigated the quality characteristics of sponge cakes with addition of paprika powders prepared from different cultivars. Powders from the special cultivar(FDFP: freeze dried fiesta paprika powder) and the fiesta cultivar(FDFP: freeze dried fiesta paprika powder) were used. The specific gravities, viscosities, heights, specific volumes, colors, textures and sensory evaluations of cake dough containing 2, 4 and 6%(all w/w) paprika powders were measured. Specific gravity and viscosity tended to increase on addition of paprika powder. Cake height and specific volume tended to decrease on addition of paprika powder. Substitution of paprika powder for flour also resulted in decreased yellowness and lightness, and increased redness, of the cake crust. The hardness of cakes containing paprika powders was higher than that of control cakes without paprika powders. Thecolor of the cake crust became darker as the amount of paprika powder increased. The results of sensory evaluation by quantitative descriptive analysis showed that the overall acceptability of sponge cakes containing 4% paprika powder, from either cultivar, was higher than that of control cakes without paprika powder.
