Seven different cultivars of Korean red pepper, Capsicum annuum L., were collected from different growing areas and analyzed for pungent principles, redness, size and weight. Length of the pod varied in the range of $7.0{\sim}9.4\;cm$ total weight, $1.2{\sim}3.1\;g$, capsaicin content, $11.5{\sim}45.0\;mg%$, dihydrocapsaicin content, $8.5{\sim}35.1mg%$, and redness (absorbance at 460 nm), $6,270{\sim}7,810$ conventional color unit. Contents of capsaicins and redness were significantly different according to the cultivars but the two components were not correlated each other. According to the growing areas, contents of capsaicins and redness were significantly different. Capsaicins content was not significantly different but redness was significantly different between sun-drying and hot air-drying of the pods.

Kochujangs (red pepper pastes) were mashed with the variation of seed content in the red pepper powder, i.e. none (plot A), 10%(B), 20%(C), 40 %(D) and 50%(E), and chemical compositions and qualities of the products were analysed and compared. Contents of amino nitrogen, reducing sugar and ethanol were high in the plot A and B, whereas lower levels were detected in the plot C, D and E. Differences in the contents of moisture, crude protein, crude fiber and sodium chloride were not significant among the plots, however, the plot D and E showed higher crude oil contents and pH as compared with the others. The plot B and A showed higher acidic protease and saccharogenic amylase activity as compared with the others. Taste, flavor and color were evaluated for the products which aged for 3 months, and better results were obtained in the plot A and B than in D and E. Especially the products of D and E were inferior in color.

Gochujang, a kind of fermented red pepper paste with soybean koji, is a traditionally using spices in Korea and is characterized by its special taste in combination with hot, sweet and salty taste, and its component are consist of protein, carbohydrates, capsanthin and capsinoids, vitamin and other minor components. We tried to develop Gochujang sauce characterized by mild hot and spicy taste, proper viscosity and its strong application to steak, fried food, pizza and others. Gochujang sauce tended to show strong red color and lightness as pH decreases and Paprica oleoresin improved a value to 12.11 and L value to 24.24 which is similar to tomato paste 1:1-1.5:1 ratio of Gochujang and tomato paste was evaluated to be acceptable in the aspect of Gochujang's characteristics.

In this research, the contents of capsaicin and dihydrocapsaicin in various species of red pepper produced in the Goesan-gun County were determined by GC-MS. Further, the contents of capsaicin and dihydrocapsaicin in powdered red pepper products with very hot, hot, normal and mild taste were analyzed to present the degree of hot taste in their products based on contents of capsaicin. The contents of capsaicin in each species of red pepper were from 25.18 mg%(Daetong) to 123.62 mg%(Cheongyang). In the powdered red pepper sold in the market, the contents (mg%) of capsaicin in very hot, hot, normal and mild taste products were 101.98, 67.63, 37.74, and 14.73, respectively. Based on this result, the classification of hot taste by contents of capsaicin was presented in the 7 grades. Namely, the products currently sold in the market were classified into very hot, hot, normal and mild taste. In this research, the degree of hot taste was classified based on contents of capsaicin into 1st grade over 120 mg%, 2nd grade in 100-120 mg%, 3rd grade in 80-100 mg%, 4th grade in 60-80 mg%, 5th grade in 40-60 mg%, 6th grade in 20-40 mg% and 7th grade below 20 mg%. Thus, it is expected that the problem which arises when preparing the products such as kimchi, gochujang and seasoning sauces by using powdered red pepper, namely, the inconsistency of hot taste can be improved and maintained.

Quality characteristics of 3 kinds of kochujang were investigated during 6 months of fermentation in order to improve the quality of industrial kochujang to that of traditional one. Three different kinds of kochujang were prepared using Aspergillus oryzae, Aspergillus oryzae plus Bacillus licheniformis and Aspergillus oryzae, Bacillus licheniformis plus Saccharomyces rouxii. Kochujang prepared with all three microorganisms contained lesser amounts of free sugar than the other preparations and glucose was the most abundant free sugar found. Ethanol was the most abundant amount among alcohols in kochujang. Kochujang prepared with A. oryzae, B. licheniformis plus S. rouxii has more amino nitrogen content than that prepared with A. oryzae only. Capsaicin contents of kochujang decreased slightly in all three kochujang, but there was no significant differences. The results of sensory evaluation showed statistically significant difference among three samples and panel members preferred the taste and flavor of kochujang prepared with all three microorganisms to those of the other samples.

최근 여러 연구보고에 의하면 capsaicin은 항암, 진통 효과 등을 갖고 있는 것으로 알려져 있으며, 음식에 독특한 색, 맛, 향기를 제공하고 강한 항산화 작용으로 유지의 산패를 억제하는 역할을 하고 있다. 따라서 본 연구는 capsaicin을 고추씨기름을 이용하여 축산식품 조리 시에 첨가될 것을 기대하여 그 함량을 조사하였다. 연구의 결과 농협, (주)오뚜기, (주)사임당의 고추씨 기름이 수안보에서 구입한 고추씨기름보다 capsaicin의 함량이 적은 것으로 나타났다. 농협, (주)오뚜기, (주)사임당의 고추씨기름은 정제와 탈취공정을 거치면서 capsaicin의 함량이 줄어든 것으로 사료되어 정제와 탈취공정 시에 capsaicin의 함량이 줄어들지 않게 하는 방안의 모색이 필요하다.

The competitions were made between two kinds of Kochujang, one is the native fermented Kochujang which is fermented at 20$\pm$2$^{\circ}C$, and the other is quick fermented Kochujang which is maintained at 35$\pm$2$^{\circ}C$ for 30 days. The results were showed that the general compositions, amino acid, nitrogen and flavor of quick fermented Kochujang were superior to the native fermented Kochujang.

To improve a low-salted yacon pickle, the change of quality characteristics during the storage of yacon pickles were investigated at $18^{\circ}C$ for 50 days using two-way ANOVA. One factor that was added was the leaf-mustard and pepper (A), the other was storage time (B). The leaf-mustard and pepper were added to increase the yacon pickle's taste, flavor, and properties. The sugar content, total acidity and salinity were significant for factor A and B. With the interaction effect of the two factors, yacon pickles increased as storage time increased. The L value was not significant for factor A but significant for factor B. The a and b values were significant for the two factors. All Hunter's color value had the interaction effect. The shearing force was not significant for each factor, and yacon pickles did not show a softening effect. In the results of the sensory evaluation, color, taste, and overall preference were significant for factor A and B, yet the flavor was only significant for factor B. The texture was not significant at all. In the overall preference, yacon pickles were higher at 30 and 40 days and also, had the interaction effect. Yacon pickles were not above the 3.0% of salinity.

The contents of capsaicinoids, free sugars and organic acids of 10 Korean varieties of red pepper power were measured and the sensory properties of their water extracts were compared in order to investigate the influence of the composition of taste components on sensory acceptability of Korean red pepper. The composition of taste components in red pepper powder varied widely depending on the varieties; total capsaicinoid content varied from 0.029 to 0.296%, free sugar $8.45{\sim}15.21%$ and organic acid $4.58{\sim}17.54%$. Capsaicinoid contents, especially dihydrocapsaicin content, were highly correlated with the pungent taste of the water extract of red pepper powder (r=0.870), but did not show significant relationship to the overall sensory acceptability. The sensory overall acceptability was highly influenced by the contents of total sugar (r=+0.815), reducing sugar (r=+0.805), glucose (r=+0.814) and fructose (r=+0.787). Multiple regression with total sugar $(X_1)$, total capsaicin $(X_2)$ and total organic acid contents $(X_3)$ increased the correlation coefficient for sensory acceptability(Y) to R=0.9008. From the result, a regression equation of $Y=0.9808X_1-10.7526X_2-0.1664X_3-4.1147$ was obtained.
