To investigate effective constituents of the many taste components in ordinary Korean soy sauce, we analyzed free amino acids, organic acids, free sugars and saline as taste components in ordinary Korean soy sauce, and determined sensory score of the ordinary Korean soy sauce taste with 45 persons of the trained pannels. The relationships between original data transformed with variables and sensory score of the ordinary Korean soy sauce were analyzed by stepwise multiple regression analysis. Eighty five percents of the ordinary Korean soy sauce taste is affected by twenty one kinds (Isoleucine, Leucine, Valine, NaCl, Lactic acid, Alanine, Phenylalanine, Tartaric acid, Sugar(\ulcorner), Proline, Malic acid, Glycine, Tryptophan, Arginine, Glutaric acid, Maltose, Histidine, Glucose, Fructose and Serine) of the taste components by stepwise multiple regression analysis of original data. Eighty one percents of the ordinary Korean soy sance taste is affected by sixteen kinds (Lactic acid, NaCl, Fumaric.Succinic acid, Tyrosine, Tartaric acid, Glycine, Malonic acid, Malic acid, Tryptophan, Glutaric acid, Methionine, Histidine, Cysteine, Maltose, Fructose and (Glutamic acid) of the taste components by stepwise multiple frgression analysis of original data transformed with square root. Eighty five percents of the ordinary Korean soy sauce taste is affected by nineteen kinds (Fumaric.Succinic acid, Lactic acid, Phenylalanine, NaCl, Tyrosine, Sugar(\ulcorner), Tartaric acid, Leucine, Glutaric acid, Methionine, Glycine, Tryptophan, Histidine, Proline, Cysteine, Glutamic acid, Maltose, Threonine and Oxalic acid) of the taste components by stepwise multiple regression analysis of original data transformed with logarithm.

한국 재래식 된장의 맛 성분이 어떠한 함량 조성일때 된장맛이 최적인지를 알기 위하여 맛 성분 분석 결과와 관능 검사 성적으로 주성분 분석과 단계별 중회귀 분석을 실시하고 각 성분의 맛에 대한 기여도를 산출하여 재래식 된장 맛 성분 조성의 최적화를 시도하였다. 재래식 된장의 맛 성분 조성의 최적화는 제곱근으로 처리했을때 고미성분인 leucine 14.7%, isoleucine 12.7%, methionine 5.0%, histidine 4.7%, arginine 1.1%, 지미성분인 cysteine 8.4%, aspartic acid 2.0%, glutamic acid 0.7%, 감미성분인 threonine 6.3%, ser-ine 5.6%, sucrose 4.7%, glycine 1.6%, Iysine 1.2%, fructose 0.6%, alanine 0.4%, glucose 0.3%, 산미성분인 oxalic acid 3.9%, succinic-fumaric-citric acid 3.6% 및 염미성분인 ash 0.3% 둥 19종의 성분으로 된장맛의 좋고 나쁨을 78%수준까지 설명 할 수 있었다. 재래식된장의 맛 성분 조성을 최적화하기 위한 중회귀 기법은 제곱근으로 변수 변환한 경우가 관능검사 성적을 가장 잘 설명 할 수 있었다.

Soysauce was made in the salt concentrations of 22.0% and 28.5%, and the changing aspects in nucleotides and their related compounds, free amino acids, free sugars and non-volatile amines which are related to the taste components during the fermentation process with a view to examining the taste components in the ordinary Korean soysauce were studied. And then artificial soysauce was prepared by applying the values derived from the analysis and measurement, and its sensory evaluation was performed. As the result of the sensory evaluation of artificial soysauce prepared according to the value of components analyzed from soysauce which had been fermented for fourty days in the salt concentration of 22.0%, it has been found that artificial soysauce was similar in taste to ordinary Korean soysauce. So, the following facts have been found: glutamic acid and aspartic acid have MSG-like taste, and IMP has a synergistic effect with these acids, which play great roles in ordinary Korean soysauce; both free sugars such as galactose and amino acids such as glycine, alanine and lysine have sweet taste; both amines such as tyramine and histamine, and amino acids such as valine, leucine, isoleucine, and phenylalanine have bitter taste; these components, combined with saline taste of salt and sour taste of organic acids, are assumed to form the unique taste in the ordinary Korean soysauce.

This studies was conducted to elucidate the taste components of shellfishes, producted in Korea. Four kinds of shellfishes including sea mussel, short-necked clam, corb shell and ark ahell were selected according to the higher sales order and cheaper retail price at 50 fish markets in Seoul in August 1982. The results are : Palatable taste of shellfishes should be caused by nucleotide related products, organic acids and free amino acids. Thus taste components found in four shellfishes were succinic, fumaric, and lactic acids as organic acids, glycine, alanine and glutamic acid as free amino acids.

시금장의 품질표준화를 위하여 시금장의 제조방법을 조사하고, 시금장의 각종 맛성분과 관능검사 점수사이의 관계를 통계적으로 분석하여 시금장의 맛에 영향을 미치는 성분을 밝히고자 하였다. 시금장의 제조방법은 훈연과정을 거치는 것이 매우 특징적이었다. 시금장의 맛성분 중 아미노산의 함량은 proline>valine>glutamic acid>alanine의 순으로 높았다. 유기산은 acetic acid와 propionic acid만이 검출되었다. 유리당은 glucose>maltose>fructose>inositol>mannitol의 순으로 많은 함량을 보였다. 각 성분의 함량과 관능검사 점수 사이의 단일상관은 전체적으로 낮아 시금장의 맛을 한개의 성분만으로 설명할 수 없었다. 가장 상관이 높은 성분은 inositol과 fructose였다. 단계적 중회귀분석을 행한 결과 절대치와 상대치의 대수변환에서 각각 17와 16개의 성분으로 시금장 맛의 90%를 설명할 수 있었다.

This study was conducted to evaluate the prediction of sensory attributes of tobacco smoke by the use of volatile oil components of tobacco. For analytical and sensory evaluations, twelve aging tobaccos (i.e., 3 crop years; 1998, 1999, 2000, and 4 stalk positions) were prepared in flue-cured and burley tobaccos. 61 volatile oil components and 5 sensory attributes such as irritation, impact, after taste, bitter and green were investigated. Irritation of flue-cured tobacco, and irritation and impact of burley tobacco were significantly increased with the ascending stalk position, whereas after taste of burley tobacco was significantly decreased. Significantly positive correlations among irritation, impact, and bitter were observed in flue-cured tobacco. A significantly positive correlation between irritation and bitter was observed, significantly negative correlations between after taste and irritation and between after taste and impact were observed in burley tobacco. Except for green of burley tobacco, all probabilities of multiple linear regression equations between volatile oil components of tobacco and sensory attributes of tobacco smoke were significant(P$\leq$0.05). This study suggests that the multiple linear regression equations may be useful to predict the sensory attributes of tobacco smoke with a few selected volatile oil components of tobacco.

This study investigated conditions necessary for factory production of traditional Korean soy sauce flavors, using Bacillus licheniformis SSA3-2M1. We determined whether the flavors were good or bad by comparing sensory evaluation values and the contents of the main taste components of traditional Korean soy sauce with those of the manufactured soy sauce. The soy broth was cultured by Bacillus licheniformis SSA3-2M1. By providing from 1/3 vvm to 2/3 vvm of air, and a culturing time of 412 hours at 30$^{\circ}C$, we produced the taste of traditional Korean soy sauce; moreover its PH was in the PH range of traditioal Korean soy sauce. The distributions of the main taste components and the amino acids, free sugars, and organic acids in the manufactured soy sauce were similar to tradituioal Korean soy sauce.

본 연구에서는 맛성분과 관능검사자료를 중회귀 분석하여 보리간장 맛을 평가하였다. 단순상관에서는 proline, alanine, methionine, lysine, histidine, lavulinic acid, ${\alpha}$-ketogutaric acid 및 citric acid와 관능검사 점수사이의 상관계수가 유의성이 높은 것으로 나타났으며, threonine, serine, cystein, phenylalanine, succinic acid, arabinose, xylose 및 sucrose 둥의 성분은 관능검사 점수에 거의 상관이 없는 것으로 나타났다. 하지만 단순상관분석으로는 보리간장 맛의 품질을 측정하는 것이 불가능하였다. 중회귀 분석을 실시한 결과 결정계수가 0.93 이상을 나타내어 맛성분 함량과 중회귀식을 이용하여 보리간장 맛의 93%를 추정하는 것이 가능하였다.

In order to investigate fermenting conditions and the microorganisms necessary for factory production of traditional Korean soy sauce, we manufactured soy sauce made by Bacillus species SSA3-2M1 and fused ST723-F31 with aeration (1/30 vvm, 113 vvm and 2/3 vvm) at $30^{\circ}C$ for 40 days. This method was chosen to investigate the changes of dissolved oxygen, pH, cell number, flavor and the taste components during fermentation. When air was supplied (2/3 vvm) to the fermentor during fermentation, the flavor of the soy sauce and the composition of taste components (free amino acids, free sugars and organic acids) were similar to that of traditional Korean soy sauce after 22 days. The results of our experiments indicates that the mass production of traditional Korean soy sauce is possible using Bacillus species SSA3-2M1 and fused ST723-F31 given sufficient aeration.
