This study was carried out in order to analyzed the changes in nitrogen containing taste compounds of three different types of traditional Korean soy sauce with varing ripening period, and to investigates correlation between sensory characteristics and taste compounds contents via contents assay and sensory evaluation of soy sauce samples. Total nitrogen, ammonia type nitrogen and amino type nitrogen contents showed the highest value in Kyupjang. 17 kinds of free amino acid was detected in Chungjangs and 16 kinds of free amino acid was detected in Kyupjang. Nucleotides and their related compounds detected were hypoxanthin, xanthin, IMP, AMP, Inosine, ADP. Free amino acid and nucleotides and their related compounds contents were highest in Kyupjang. Nitrogen related compounds content of high concentration soy sauce ripened over 150 days increased similarly with Kyupjang. In the sensory evaluation of soy sauce taste, Chungjang samples acquired the highest score in the offensive taste test while Kyupjang marked highest score for sweet taste, nutty taste, taste preference. High concentration soy sauce ripend over 150 days yielded the result similar to that of Kyupjang. Sweet taste showed positive correlation with nitrogen compounds. The materials that showed positive correlation with nutty and traditional soy sauce taste and taste preference were nitrogen compound, IMP, AMP. Except for tryptophan, all free amino acid showed positive correlation with nutty and traditional soy sauce taste. Particulary, taste preference correlated to lysine, aspartic acid and glutamic acid.

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.

This study was carried out in order to analyze the changes in nitrogen containing taste compounds of traditional Korean soy sauce with varying Meju concentrations (Meju-water ratios of 1:4 and 1.3:4) and ripening periods (up to 2 years), and to investigate correlation between sensory characteristics and taste compound contents via contents assay and sensory evaluation of soy sauce samples. Nitrogen compound contents were higher in 1.3:4 than in 1:4 for all nitrogen compounds. Free amino acid contents were highest in soy sauce ripened for 210 days. Among amino acids, glutamic acid was highest concentration. Nucleotides and their related compound contents did not vary with concentrations and were highest in the sample ripened for 210 days. In direct sensory evaluation of soy sauce, overall taste preference showed positive correlation to sweet taste. Likewise, overall taste preference showed positive correlation to umami, nutty, sweet taste in the sensory evaluation of seaweed soup seasoned with soy sauce. Sensory evaluation score was higher in 1.3:4 than in 1:4. According to the correlation assay of taste compound contents and sensory evaluations, nitrogen compounds (such as amino type nitrogen), amino acids (such as glutamic acid, aspartic acid, and lysine, and etc.), nucleotides (such as AMP, IMP, and etc) had significant influence on the sensory characteristics of soy sauce, and therefore we can conclude that these compounds affect the taste and quality of soy sauce.

This study was conducted to investigate the changes in organoleptic characteristics by adding different amounts of red pepper powder, salt-fermented anchovy extracts to kimchi. The salt enhanced sourness and pungency up to 2% but suppressed sourness, pungency, sweetness and umami taste by salt of more than 2%. Red pepper powder proportionally enhanced sourness up to 3% but suppressed saltiness, sweetness and umami taste. Salt-fermented anchovy extracts enhanced saltiness and sweetness together with enhancement of umami taste, but suppressed pungency and sourness. As the result of one-way analysis of correlation with the above tastes of spices and kimchi, saltiness of NaCl had a significantly negative correlation with pungency, sourness, sweetness and umami taste, as -0.9857, -0.9878, -0.9847, -0.9076, respectively, and pungency of red pepper with sourness, sweetness, saltiness and umami taste, as -0.8353, -0.9316, -0.9020, -0.9901, respectively. This indicated that increase of pungency and saltiness of kimchi suppressed a overall taste of kimchi. In addition, umami taste had a significantly negative correlation with only pungency as -0.9823 and a significantly positive correlation with sweetness and saltiness, showing a different tendency with pungency and saltiness.

Objectives: This study evaluated the correlation between taste function and spleen qi deficiency in patients with burning mouth syndrome (BMS) and compared subgroups of BMS (i.e., dysgeusia and non-dysgeusia subgroups). Methods: This study included 60 participants categorized into two groups: a BMS group and healthy control (HC) group. Taste threshold was measured within six levels using solutions of four basic taste qualities. Subjects' Oral Health Impact Profiles (OHIPs-14) and Spleen qi Deficiency Questionnaire (SQDQ) scores were analyzed. Results: Taste thresholds for sweet (sucrose) and salty (NaCl) tastes were significantly lower in the BMS group than in the HC group, but sour (citric acid) and bitter (quinine HCl) tastes showed no significant differences between groups. In the dysgeusia and non-dysgeusia subgroups, no significant differences in the four basic taste thresholds were found. SQDQ scores were significantly higher in the BMS group compared to the HC and in the dysgeusia group compared to the non-dysgeusia group. OHIPs-14 and SQDQ scores for the BMS group were significantly and positively correlated. Conclusions: Spleen qi deficiency is related to taste function and can be used to treat BMS patients with taste dysfunction.

The literature suggested that a small reduction in overall blood pressure can have a large effect on overall prevalence of hypertension, and therefore, the affect of taste preferences of the population on salt intake should be considered for long-term blood pressure intervention programs. The purpose of this study is to investigate the influence of salt taste preference and salt taste sensitivity on salt intake behavior as risk factors for high blood pressure. We collected information on blood pressure, diet and lifestyle behaviors, salt taste preference and salt taste sensitivity from 540 respondents from Suseo-dong, Seoul. Salt taste sensitivity was assessed by administering a 1% NaCl solution to the subject's tongue and measuring the perceived intensity on 10 level scale. Salt intake behavior was classified into 3 categories: frequency of high-sodium foods, practice of salt-reducing behavior and frequency of vegetable and fruit intake. Salt taste preference showed a significant relation to the subjects' blood pressure, i.e. subjects with a higher salt preference had higher blood pressure. Salt taste sensitivity did not show a significant relation to blood pressure. However, there was a positive correlation between salt taste preference and salt taste sensitivity. Among the 3 indicators used to measure salt intake behavior, the practice of salt-reducing behavior remained significantly correlated to blood pressure. Moreover, salt-reducing behavior and salt taste preference showed a significant correlation, i.e. people who do not like salty foods tend to practice more salt-reducing behavior, leading to reduced levels in blood pressure. In a population, a small reduction in overall blood pressure can have large effects in overall prevalence of hypertension, in contrast to clinical studies where achievement of an individual's normal blood pressure is emphasized. Therefore, taste preference of the population should be considered for long-term blood pressure intervention programs.

To obtain a clear understanding of the degree of effect by the food color in diet habits, this study was a survey of the taste for food color. In this study, the term of investigation was tow months(May and Jun. 1992), the object was 10's∼50's women, and the sampling of them at random contain 100 person, respectively. The data-treatment was determinded by frequency, percentage, SD, Chi-square, Spearman's rank order correlation coefficient, Correlation, F-test as measured by SAS program for PC and statistical figures were obtained by GDAS. The results were as follows; 1. Food color in diet habits. : The relationship of food color with appetite by age group was showed to affect all age groups having more then 90%. The concern for food color by age group showed the lowst teenage having 56.7%, showing more then 70% except teenage. When chosen food, The most important characteristics of food was not age group but taste. In the correlation between characteristics, The correlation between color and form, taste and nutrition was showed affirmative. The difference test for the taste of food color and general color was shown, and the level of significance was chosen at 95%. 2. In the correlation between food color and the sense of emotion, The food color of depression and solitude was purple, the color of sadness and crying was white. But in case of only solitude, A statistical significance was shown. 3. In the investigation of taste for food color, the mean of taste degree was high in red, orange, yellow, yellowish green, green, white and low in blue, black. Their statistical significance was shown between colors but, was not shown between age groups. 4. In the relation of food color and associated with food, the colors of associated with food shown a vast difference with natural food color were blue(85.5%), purple(80.0%), pink(41.7%) and yellow(40.0%) but, A red color was not shown the error rate of associated with food color at all. Almost all kinds of associated with food were fruits and vegetables.

The purpose of this study was to compare regional differences in salty taste assessments, nutrition knowledge, dietary attitudes and dietary behaviors associated with high-salt diets in four national regions in Korea (Region 1: Seoul, Sokcho, Region 2: Buyeo, Jecheon, Gong Ju, Region 3: Daegu, Gyeongsan, Region 4: Jeon Ju). Subjects were 860 persons who participated in sodium reduction campaign. The result of the salty taste assessment by region was not significantly different. The nutrition knowledge score of subjects in Region 1 was the highest. Dietary attitude scores that showed preference for high-salt diets of Region 2 and Region 4 subjects were higher than those of Regions 1 and 3 subjects (p < 0.001). Dietary behavior scores were not significantly different among regions. The correlation between sodium intake and salty taste assessment was significant (p < 0.01). Older subjects who had high blood pressure levels and lower nutrition knowledge were more likely to have high sodium intakes. Even though the salty taste assessment and dietary behavior scores by region were not significantly different, the salty taste assessment scores had a significant negative correlation with nutrition knowledge and had a significant positive correlation with dietary attitude and dietary behavior in terms of preference for high-salt diets. Therefore, nationwide education regarding salt intake reduction and health and a campaign to encourage favorable attitudes and behavioral changes regarding consumption of a no-salt / low-salt diet is needed.
