다양한 분야에서 시도된 문화 교류 중, 가장 성공적인 혼합은 바로 음식문화의 결합으로 동서양의 맛을 혼합한 Fusion 음식이라고 할 수 있다. Fusion 음식은 세계적인 추세를 보더라도 국내에서 잠시 유행하다가 사라져버릴 장르의 요리는 결코 아니며, 오히려 더욱 다양한 형태의 Fusion 음식을 표방하는 레스토랑들이 생겨날 것이다. Fusion음식이 국적 없는 음식으로서 전통의 맛을 죽인다는 비판도 있지만, 올바른 Fusion 음식은 그저 무국적 음식이 아니라 오히려 전통의 맛을 이어가면서 발전시키는 다음 단계로 보는 것이 정확 할 것이다. Fusion 음식은 결국 여러 나라의 식문화를 합친 결과로, 각 나라의 기본적인 식문화에 바탕을 둔 조리기법이다. 다시 말해서 Fusion 음식의 뿌리는 수백 수 천년을 거슬러 올라가 각 나라의 전통음식이라고 할 수 있으며 오히려 동.서양의 기본적인 조리기법을 완벽하게 숙달해야만 성공적인 Fusion 음식을 구연할수 있는 것이다. 국내에는 이러한 기본적인 원칙이 무시된 채 급하게 도입되면서 현재 다소 침체된 느낌이지만 이 같은 단계를 통하여 발전될 것이고, 이러한 바람직한 경쟁과 연구를 통해 선진국에 비해 현실적으로 현저하게 뒤떨어져 있는 한국의 식문화 수준도 높아질 것이다. 그러나 아무리 새로운 음식과 재료가 쏟아져 들어온다 하더라도 그것을 주체적으로 소화해낼 수 있는 문화적 잠재력이 없다면 "Fusion" 이 라는 것도 단지 한때 흘러가는 하나의 유행일 수밖에 없다. 따라서 한국적인 Fusion 요리의 개발을 통하여 외국인들에게 거부감 없이 쉽게 한국의 맛을 전하고 한국음식의 세계화를 보다 효과적으로 이룰 수 있어야 할 것이다. 특히 된장, 고추장, 김치 등 발효음식의 특성을 살린 Fusion 음식을 개발해 한식의 세계 상품화를 시도해야할 시점이다.

Kochujang was prepared by replacement of rice (25%, control) with pumpkin or purple sweet potato by 0. 5, 10, and 15% (total addition ratio of rice and sweet potato=25% of sample). Effects of the addition of sweet potato on physiochemical properties of fermented Kochujang were investigated. Viable cells of yeast decreased in the sweet potato-added Kochujang at the later stage of fermentation, while there was no significant difference in the number of bacteria among the test groups. As the addition ratio sweet potato increased, ${\alpha}$-amylase activity increased while protease activity decreased. Hunter L, a, and b values of Kochujang prepared with purple sweet potato were lower than those with pumpkin sweet potato. Changes in ${\Delta}E$ value was greater in Kochujang prepared with pumpkin sweet potato than that with purple sweet potato. Oxidation-reduction potential and water activity were higher in sweet potato-Kochujang than control, but reducing sugar content was higher in control. Alcohol and amino-type nitrogen contents were higher in Kochujang prepared with pumpkin sweet potato than that with purple sweet potato, but it was not significant. Overall sensory acceptability was highest in Kochujang prepared with 10% of purple sweet potato while that with 15% pumpkin sweet potato was the least preferred.

This study is a continuous work for the standardization of children's kimchi preparation. In order to find out the proper red pepper powder for children's kimchi, four kinds of red pepper powder(A, B, C, D) sold in Kyungsang province were used as samples. The proximate composition, color value, capsaicinoids concentration and sugar content in four kinds of the red pepper powder were determined, and sensory evaluation of kimchi Prepared with those was carried out for different fermentation times. Moisture contents of red pepper powder A, B, C and D were in the range of 11.59~13.48%. Lipid and ash contents of samples were in the range of 7.59~8.39% and 4.34~7.45%, respectively. In comparision of color values measured by a Hunter colorimeter, red pepper powder A showed the highest value for a and b values. Also A showed the brightest color as measured in ASTA color and L value. Capsaicin concentration of D and dihydrocapsaicin concentration of C were found to be the highest among the sanlples. The capsaicin equivalent was in tile order of D>C>A>B. The content of total sugar was in the order of B>A>D>C. In the sensory evaluation of children's kimchi prepared with four kinds of red pepper powder, the color and total acceptability of kimchi prepared with A were found to be the best. The results of sensory evaluation between kimchi prepared with A and school supplied kimchi showed that the former was better. And the composition of A red pepper powder was as follows: capsaicin equivalent 24.l5mg%, total sugar content 15.79% and ASTA color value 178.2.

A part of Aspergillus oryzae koji was replaced with Bacillus sp. koji to improve the quality of kochujang, and the resulting effects on enzyme activities, microbial characteristics, and physicochemical properties were investigated during fermentation. The activity of amylase was higher in the kochujang prepared with Asp. oryzae koji. The activity of protease increased as the ratio of Bacillus. sp. koji increased. Viable cell counts of yeast and bacteria of the kochujang increased with increasing ratio of Bacillus sp. koji. The Hunter a-values of the Bacillus sp. koji kochujang were higher, and the degree of increase in the total color difference $({\Delta}\;E)$ was lower in the Bacillus sp. koji group. Consistency and water activity of the kochujang prepared with Bacillus sp. koji was higher, and the pH and titratable acidity of the kochujang also changed slightly. As the ratio of Asp. oryzae koji increased, sugar content decreased. However, the ethanol content of the kochujang did not significantly change. Amino nitrogen content of the kochujang increased, while ammonia nitrogen content decreased as the ratio of Bacillus sp. koji increased. After 12 weeks of fermentation, the result of sensory evaluation showed that C kochujang (75% of Asp. oryzae koji replaced by Bacillus sp.) was more acceptable (p<0.05) than the other groups in taste, color, flavor, and overall acceptability.

Gochujang sauces were prepared with 5, 10, 15, and 20% concentrated pomegranate juice(CPGJ) and analyzed with the control for quality characteristics such as proximate composition, viscosity, pH, acidity, $^{\circ}Brix$, $^{\circ}Brix$/acidity ratio, color, and sensory qualities in order to determine the optimal ratio of CPGJ in the formulation. Moisture content, crude ash, viscosity, pH, Brix/acidity decreased, while acidity, Brix increased with increasing CPGJ content. In terms of color, lightness and yellowness decreased as CPGJ content increased however, the control group had significantly(p<0.05) higher redness than the CPGJ samples. For the sensory evaluation, color was not significantly(p>0.05) different among the samples. As the CPGJ content increased, flavor, viscosity, and overall acceptability decreased, whereas sourness, acrid taste, bitterness, astringency, and off-flavor increased. In conclusion, the results indicate that the addition of 10% CPGJ to Gochujang sauce is optimal, and provides good physiological properties as well as reasonably high overall acceptability.

Taste components of traditional kochujang from 55 households were investigated. The major free sugars in traditional kochujang (fermented hot pepper-soybean paste) were glucose $(8.21{\pm}5.62%)$ and maltose $(6.95{\pm}7.27%)$ and the minors were fructose $(1.88{\pm}1.27%)$ and sucrose $(1.05{\pm}1.21%)$. Succinic $(901.83{\pm}826.23\;mg%)$, citric $(484.16{\pm}242.89\;mg%)$ and lactic $(381.63{\pm}367.88\;mg%)$ acids in traditional kochujang were found in large amounts and acetic, oxalic, and formic acids in smaller amounts. The traditional kochujang contained large amounts of proline $(10.66{\pm}6.27\;mg%)$, glutamic acid $(9.27{\pm}10.97\;mg%)$, aspartic acid $(9.14{\pm}5.84\;mg%)$, lysine $(6.19{\pm}6.66\;mg%)$, and serine $(5.72{\pm}3.79\;mg%)$, and the total free amino acid content was 64.35mg%. Among the nucleotides and their related compounds in traditional kochujang, CMP $(42.90{\pm}28.16\;mg%)$ were the most abundant major compounds and hypoxanthine $(6.86{\pm}3.45\;mg%)$, IMP $(5.59{\pm}5.84\;mg%)$, inosine $(4.58{\pm}6.91\;mg%)$ and GMP$(3.36{\pm}3.93\;mg%)$ were found in smaller amounts, and AMP and UMP were also found in minor.

Changes in quality characteristics of gochujang prepared with different ingredients (white rice, barley, sorghum and millet, bamboo salt) and meju starters were studied. The gochujang samples were fermented for 6 weeks at $40^{\circ}C$ and analyzed for changes in their physicochemical properties and sensory characteristics. Eight different gochujang samples were prepared: WR-SS-AB, WR-SS-ABL, WR-BS-AB, WR-BS-ABL, MG-SS-AB, MG-SS-ABL, MG-BS-AB, MG-BS-ABL (WR: white rice, MG: mixed grains, SS: solar salt, BS: bamboo salt, AB: Aspergillus oryzae/Bacillus subtilis starter meju, ABL: Aspergillus oryzae/Bacillus subtilis/Lactobacillus plantarum starter meju). There were significant differences between experimental groups in terms of moisture content, pH, acidity, and color value. All gochujang samples showed increased moisture contents and pH as well as increased acidity and amino-type nitrogen during fermentation. MG-BS-ABL showed the highest contents of amino-type nitrogen and free amino acids after 6 weeks of fermentation compared with other experiment groups. In addition, MG-BS-ABL showed the highest sensory analysis score, including appearance, flavor, taste, and overall acceptability after the fermentation of samples. Based on the results, MG-BS-ABL exhibited similar quality characteristics as general gochujang but showed the highest sensory scores and contents of amino-type nitrogen and free amino acids. These results might be due to the high protein contents of mixed grains and high mineral contents of bamboo salt and fermented products from mixed probiotic starters.

Physicochemical characteristics of kochujang prepared with meju, koji and mixture of meju and koji were analyzed during fermentation in order to improve quality of traditional sikhe kochujang. Amino nitrogen content, an index of kochujang quality, was remarkably higher in kochujang prepared with p-2 koji, p-1 koji, mixture of p-2 koji and meju. Titratible acidity of kochujang slightly increased and pH of kochujang increased until 40 days of fermentation and then decreased there after. Citric acid was found as a major organic acid followed in decreasing order by malic, oxalic, succinic, acetic and lactic acids. As a free sugar, maltose, glucose and fructose were detected. Free sugar content was higher in kochujang prepared with p-1 koji than the others. The major free amino acids were aspartic acid, glutamic acid, alanine, phenylalanine and arginine, and total free amino acid content was higher in kochujang prepared with koji, and mixture of meju and koji than the one with traditional meju only. In sensory evaluation, all tested groups did not show a significant difference. This result indicates that addition of koji to sikhe kochujang influences on taste components like free sugars and free amino acids, but decisively not on the sensory properties.

In order to improve qualities of traditional kochujang, pear juice was added to kochujang, and the physicoche-mical and microbial characteristics of pear-added kochujang were investigated for 2 months of fermentation at 30$^{\circ}C$. Moisture contents of pear-added kochujangs increased except of 9$\%$ pear-added kochujang and crude protein contents of them decreased as the fermentation proceeded. Total sugar contents of pear-added kochujangs did not change during the fermentation period, and reducing sugar contents of them increased remarkably from early stage of fermentation. The pH of pear-added kochujangs decreased and titratable acidity of them increased during fermentation. Amino-nitrogen contents of pear-added kochujangs increased remarkable after 45 days of fermentation. Viable cells counts of yeasts in pear-added kochujangs increased to 2.2$\∼$2.9$\times$$10^{3}$CFU/g, and bacterial cell counts were in relatively constant range of 2.1$\∼$2.9$\times$$10^{7}$CFU/g at the late stage of fermentation. Color of pear-added kochujangs had no difference and 'a' value decreased slightly during fermentation. The result of sensory evaluation showed that 6$\%$ pear added kochujang were more acceptable than others.

This experiment was attempted to investigate a cause of the scion death in green pepper grafting system. A tobamovirus particle examined in the rootstock of the sample but not in the scion showing necrosis. The virus isolated from the rootstock was identified as Pepper mild mottle virus (PMMoV), pepper tobamovirus pathotype P1.2. (PMMoV-2), by nucleotide sequence analysis and host plant reaction. The virus isolate infected systematically in 6 commercial rootstock varieties using for green pepper grafting seedling production. Green pepper varieties 'Long green mart' and 'Daechan' represented resistance to the virus showing local lesions only on the inoculated leaves and 'Manitda' was systematically infected. In the experiment with grafting 'Long green mart' or 'Daechan' onto the those rootstocks, the upper leaves of the scions first showed vein necrosis and wilt symptoms 7 days after inoculation with PMMoV-2 on the cotyledon of the rootstock, following to the scion stem necrosis and then only the scion death. The virus was detected in the rootstock but not in the scion. However, 'Manitda' of susceptible variety in the grafting system showed mottle symptom on the leaves of the scion but not necrosis on the plant. PMMoV-3 isolate, pepper tobamovirus pathotype P1.2.3, did not cause the scion death in the grafting system. All of the varieties were susceptible to PMMoV-3. These results suggest that the scion death is caused by infecting with pepper tobamovirus pathotype P1.2. in the green pepper grafting system combined with the susceptible rootstock and the resistance scion to the virus pathotype.
