  • This research was conducted to predict taste of barley kanjang using multiple regression analysis between taste components and sensory score. In the analysis of single correlation, the correlation coefficient of proline, alanine, Methionine, lysine, histidine, lavulinic acid, ${\alpha}$-ketogutaric acid was significant in 5% level. On the other hand, the taste of barley kanjang was not significantly effected by threonine, serine, cystein, phenylalanine, succinic acid, arabinose, xylose, and sucrose. It was impossible to measure taste of kanjang with barley bran to use simple correlation analysis. The 93% of barley kanjang taste was predicted using multiple regression analysis with taste components and sensory evaluation scores.

  • We investigated main effective taste components and optimization of taste component composition in traditional Korean soybean paste. In optimization of taste components the original data with 19 kinds of taste components which is consisted of bitter taste transformed with square root could explain the taste up to 78% (contributing proportion of leucine was 14.7%, isoleucine 12.7%, methionine 5.0%, higtidine 4.7% and arginine 1.1%), palatable taste (cysteine 8.4%, aspartic acid 2.0% and glutamic acid 0.7%), sweet taste (threonine 6.3%, serine 5.6%, sucrose 4.7%, glycine 1.6%, lysine 1.2%, fructose 0.6%, alanine 0.4% and glucose 0.3%), sour taste (oxalic acid 3.9% and succinic-fumaric-citric acid 3.6%) and saline taste (ash 0. 3%). In order to optimize the taste of traditional soybean paste, the constitution of taste components was analysed by multiple regression between the original data transformed with square root sensory scores of the soybean paste. This way explained the sensory evaluation best score.

  • The sensory characteristics of nine commercially distilled soju samples were determined by sensory descriptive analysis. Eight aroma attributes, as well as four flavor/taste attributes, and six mouth-feel related attributes were evaluated by 9 judges. The descriptive data set was initially analyzed for a significant overall product effect by employing a three-way mixed model analysis of variance (judges, samples, and replications) as well as two-way interactions, with judges treated as random. In addition, correlations between mean attribute ratings were calculated, and a principal component analysis (PCA) of the mean attribute ratings employing the covariance matrix was conducted. Based on the PCA, distilled soju samples were primarily separated along the first principal component, which accounted for 66% of the total variance between the samples, with high intensities of 'alcohol taste' and 'alcohol aroma' versus 'yeast aroma'. The second principal component accounted for 14% of the total variance. Soju containing high alcohol showed stronger intensities of 'bitterness', 'alcohol taste', 'alcohol aroma', as well as all mouth-feel attributes.

  • The sensory characteristics of cream soup containing 0, 25, 50, 75 and 100% rice flour were investigated in order to develop a new processed food using rice. The Hunter L(lightness) value increased with the amount of rice flour, while the a(redness) value and b(yellowness) value decreased, significantly. The viscosity of rice cream soup significantly decreased with the increasing amount of rice flour. Based on the sensory evaluation, the cream soup samples with larger rice flour component showed a higher clean taste score, while those with the least rice flour resulted in higher darkness, viscosity, greasy taste, md softness. The overall acceptance was the highest in the cream soup with 75% and 100% rice flour. In terms of the color and viscosity, good correlations were observed between the sensory evaluation and the objective analysis. The overall acceptance showed a significant positive correlation with a clean taste, while there was a negative correlation with a greasy taste and the viscosity measured by a viscometer.

  • The spice combinations for substitute of salty taste were developed for reducing sodium intakes in home cooking. The seventeen materials, which have been known as remedy effects for hypertension, were collected and blended based on descriptive sensory evaluation and principal component analysis. Four types of spice combinations such as nutty, umami and salty, hot and sour, and multi attribute were developed as substitutes of salty taste. The developed spice combinations were applied to mackerel meat instead of salt. Consumer acceptance of mackerel meat with spice combinations was analyzed using hedonic nine point scale by 54 panelists. As the sensory evaluation results, the consumer acceptance value of the spice combinations for substitute of salty taste with hot and sour attribute was the highest value as 6.4, whereas that of the salt was 3.1. Also, the fish and rancid flavor were the lower values in the salt free spice blends than those of salt. The spice combinations for substitute of salty taste 5% and NaCl 1%, as a control, were spread on mackerel meat and incubated at $30^{\circ}C$ for 0, 24, and 48 hours. The TBA values of the spice combinations for substitute of salty taste were shown as a half and/or one third values of salt. As the result, the spice combinations for substitute of salty taste with reducing undesirable flavor could be used in home cooking instead of salt.

  • As a part of basic investigation for utilization of canned food processing by-products, a food components of the canned oyster processing waste water such as boiled and released water(BRW), wash water(WW) were investigated and compared with hot-water extracts from oyster. From the results of measuring heavy metal conte수, viable cells and coliform group, the canned oyster processing waste waters might not invoke health risk in using food resource. The contents of taste compounds (free amino acids, ATP related compounds, TMA (O) and total creatinine) of BRW and WW accounted for about 254% and 95%, respectively, in comparison with those of control (hot-water extract from oyster). The BRW showed a very high content of salt in comparing to the WW and control. In descending order, the values of whiteness index was WW, control and BRW. Sensory scores for color, oyster flavor intensity and saline taste were not significantly different between WW and control. But, BRW had the highest score in oyster flavor intensity, while had the lowest score in color and saline taste. But, the color and saline taste of BRW might be able to control by some pretreatment (concentration and drying in mild condition, desalination and recipe control etc). These results indicated that BRW and WW generated from various step during canned oyster processing could be a potential food resource by controlling of saline taste and color intensity.

  • This study was aimed to optimize the required condition for recovering the low soluble taste component obtained from sea tangle extract using ultrafiltration, and to investigate effects of membrane type, temperature, transmembrane pressure and flow rate respectively. We also compared relationship between the profile of permeate flux and the recovery yield of taste component under the selected optimal condition using ultrafiltration and diafiltration. Hydrophobic GR 51 PP membrane kept higher average permeate flux than hydrophilic FS membrane, and average permeate flux also had increasing tendency in relation to rising flow rate but it showed limit value of 3.7 l/min. Average permeate flux decreased as transmembrane pressure increased but it showed little change with rising temperature. Investigation upon average permeate flux, total dissolved solid and recovery yield of taste components using ultrafiltration and diafiltration resulted in relatively higher recovery yield in ultrafiltration. Compared ultrafiltration and diafiltration, average permeate flux was lower in ultrafiltration.

  • In this paper, we propose a tongue diagnosis system for determining the presence of specific taste crack area as a first step in the digital tongue diagnosis system that anyone can use easily without special equipment and expensive digital tongue diagnosis equipment. Training DB was developed by the Haar-like feature, Adaboost learning on the basis of 261 pictures which was collected in Oriental medicine. Tongue candidate regions were detected from the input image by the learning results and calculated the average value of the HUE component to separate only the tongue area in the detected candidate regions. A tongue area is separated through the Connected Component Labeling from the contour of tongue detected. The palate regions were divided by the relative width and height of the tongue regions separated. Image on the taste area is converted to gray image and binarized with each of the average brightness values. A crack in the presence or absence was determined via Connected Component Labeling with binary images.

  • Sensory evaluations of synthetic extracts prepared on the analytical data in the previous papers (Yang and Lee, 1979, 1930-a, 1980-b, 1982) were undertaken to determine the origin of the taste of wild common carp, Cyprinus carpio, and Korean snakehead: Channa argus. Taste panel assessments of synthetic extracts prepared with each extractive component omitted were carried out by a triangle difference test, and changes in taste profile were assessed. The synthetic extracts, prepared with about 40 pure chemicals based on the analytical data from the species satisfactorily revealed the natural taste of the original extracts except slight difference in meaty taste and mildness. From the results of omission test the major components which contribute to produce the taste of the species were assessed as follows: glycine, glutamic acid, arginine, lysine, threonine, alanine, IMP, inosine, hypoxanthine, glucose, succinic acid, $Na^{+},\;Cl^{-}\;and\;PO_{4}^{3-}$ in common carp: glycine, alanine, glutamic acid, IMP, Na+ and $PO_{4}^{3-}$ in Korean snakehead.
