The purpose of this study was to investigate the preferences, consumption, and eating frequencies of housewives for commercialized traditional basic side dishes. The investigators visited 18 food markets and questionnaires were distributed to 464 housewives in the Busan area. The number of basic side dishes being sold at the markets were in the order of seasoned dried radish (17 markets; mk), salted garlic stalk (15 mk), braised black soy beans (14 mk), braised peppers and dried anchovies (13 mk), and braised lotus roots (12 mk). The housewives' order of preferences was for stir-fried dried anchovies, braised peppers and dried anchovies, braised seasoned beef, salted perilla leaf, and perilla leaf kimchi equal to seasoned sea lettuce, respectively. The order for eating frequency was stir-fried dried anchovies, braised peppers and dried anchovies, salted perilla leaf, and perilla leaf kimchi, respectively. Salted perilla leaf, perilla leaf kimchi, braised crab preserved in soy sauce, salted bean leaves, seasoned dried radish, and seasoned crab were either occasionally or frequently purchased by over 40% of the women. However, the reasons they did not purchase these products included: the excess use of chemical seasonings, unsanitary, unreliable cooking process, unreliable the origin, and high price, in the respective order. If the commercialized traditional basic side dishes were improved to eliminate these problems, 52.2% of the housewives would buy the products, and 65.6% anticipated increasing their use of these products in the future.

A survey was conducted to investigate housewives' perception and consumption of Korean fermented foods marketed in Taejon. Most subjects know how to prepare Kimchi(seasoned and fermented vegetables), 65-67% can make Kochujang(fermented red pepper soybean paste), Toenjang(Korean style soysauce) and Jang-atchies(pickled basic side dishes), 56% can make Kuk-ganjang(Korean style coysauce), 45% can make Chonggukjang (fermented soybean) and 34% can make Jot-kals(salt-fermented fish products). With decreasing age(p<0.0001), not many other subjects could make other fermented foods besides Kimchi. The percentages of subjects buying fermented foods were 71.5% for Chin-ganjang(Japanese style soysauce), 51.7% Jot-kals, 27.1%Kochujang, 25.7% Chonggukjang, 20.1% Jang-atchies, 10.4% Toenjang, 5.9% Kuk-ganjang, and 3.8% Kimchi. the uounger in age, the higher the tendency to buy marketed Kimchies(p<0.05) and Kochujang(p<0.01). The resons for purchasing fermented foods were convenience (52.9%), lack of preparation knowledge(17.5%), lack of time for preparation(12.5%), and lack of space for food storage(8.2%). Subjects indicated that their reasons for mot buying were as follows : use of additives or unreliability with regard to manufacturing dates(45%), bad taste(21%), unsanitary treatment(16%) and to keep their indigenous taste(14%). They cosidered expiration dates, taste, crpteria and safety as the important standard in selecting marketed foods. Younger subjects insisted on the improvement of sanitary condition and partial change of taste to increase the consumption of fermented foods. However, older subjects thought it best to keep the taste original for more utilization of fermented foods.

A survey was conducted in 591 college students using 8 different cafeterias serving 31 meals. The information was obtained about the name and amount of dishes they consumed from the menu offered by college foodservice. Mean nutrient contents per meal in offered menu were higher than 1/3 of RDA for their age, sex in offered menu. The mean energy content was 466kcal from rice, 113kcal from soup, 141kcal from side dish and 21kcal from kimchi. When side dishes were classified by cooking methods, side dishes using grilling, frying, roasting methods had high energy content and fat percent above 200kcal, 40% per dish. By main ingredients, side dishes with animal food were higher energy than with plant food. Students consumed 94% of the energy provided in offered menu. When compared to proportion of foods consumed by sex, there was 43% of female and 22% of male consumed less than half in soup and 31% of female and 12% of male in kimchi. The most prevalent menu patterns of subjects included rice, soup, 2 side dishes, kimchi and were the same in both sexes. Mean energy intakes per meal were 989kcal for males and 842kcal for females which were enough to meet 1/3 of RDA for their age and sex. Most nutrient intake except fat and vitamin B1 were higher in set menu than in cafeteria. Nutrient adequacy ratio(NAR) were above 0.9 except calcium and vitamin A. The mean energy intake was 542kcal from rice, 70kcal from soup, 164kcal from side dish and 20kcal from kimchi. In conclusion, intake of most of the nutrients of students obtained from males in college foodservice were sufficient but calcium intake was insufficient and fat content was above 20% of energy. High fat consumption was due to side dishes from frying, grilling, roasting with animal food. To provide desirable meals in college foodservice, use of fat in cooking must be decreased.

고추 자원을 최대 활용하고, 농가의 수익을 올리기 위하여, 청고춧가루로 김치를 제조한 후 홍고춧가루와 김치와 pH, 총산도, 생균수, 젖산균수 및 관능 등을 비교 검토하였다. 청고추 김치와 홍고추 김치의 pH 및 총산도의 변화 양상은 거의 같은 것으로 나타났다. 또한 두 김치의 적숙기 초기에서 말기까지, 생균수와 젖산균수에 있어서도 거의 같은 양상을 보였다. 그리고 관능은 청고추 김치가 홍고추 김치에 비해 전반적으로 아주 낮은 값을 보였는데, 이는 김치의 붉은 색에 대한 기본 관념 때문인 것으로 사료된다.

Plant pathogenic RNA viruses are present in a variety of plant-based foods. When ingested by humans, these viruses can survive the passage through the digestive tract, and are frequently detected in human feces. Kimchi is a traditional fermented Korean food made from cabbage or vegetables, with a variety of other plant-based ingredients, including ground red pepper and garlic paste. We analyzed microbial metatranscriptome data from kimchi at five fermentation stages to identify plant RNA virus-derived sequences. We successfully identified a substantial amount of plant RNA virus sequences, especially during the early stages of fermentation: 23.47% and 16.45% of total clean reads on days 7 and 13, respectively. The most abundant plant RNA virus sequences were from pepper mild mottle virus, a major pathogen of red peppers; this constituted 95% of the total RNA virus sequences identified throughout the fermentation period. We observed distinct sequencing read-depth distributions for plant RNA virus genomes, possibly implying intrinsic and/or technical biases during the metatranscriptome generation procedure. We also identified RNA virus sequences in publicly available microbial metatranscriptome data sets. We propose that metatranscriptome data may serve as a valuable resource for RNA virus detection, and a systematic screening of the ingredients may help prevent the use of virus-infected low-quality materials for food production.

Today, energy bars are consumed not only as snacks but also as meal replacement foods. Convenience and nutritional supplementation are the main factors accounting for the increasing use of energy bars. Two hundred Chinese customers who attended the China Fisheries & Seafood Exposition in China, and had no inhibitions about consuming cereal bars were selected. The questionnaire was composed of CATA choices that selected both the reasons for liking and disliking four different types of cereal bars, namely topokki flavor (hot pepper paste), seaweed flavor, kimchi flavor, and ginseng flavor cereal bars with 10% of dried anchovy content produced by BadaOne Co. (Seoul, Korea). The purpose of the study was to investigate Chinese consumer's attitudes and acceptance of different flavored cereal bars containing protein and calciumrich anchovy. For the selected Chinese customers, the acceptance score for the seaweed flavor was the highest, followed by topokki, red ginseng, and kimchi. The acceptance for the topokki flavor was higher than for seaweed for the attributes of color except for general acceptance, flavor, aroma, and texture. The results of the survey showed that the acceptance of kimchi was the lowest, contrary to earlier predictions. The results of the Check All That Apply (CATA) analysis showed that the reasons for liking the seaweed & anchovy flavor were the most diverse, and there was no reason chosen for disliking this flavor. The reasons for liking this flavor were listed as sweet flavor, healthy, seafood flavor, malty flavor, texture, new/unique, and umami. In the case of topokki and kimchi, the reason for disliking the flavor was umami, and in the case of red ginseng, the ginseng flavor was the reason for both likes and dislikes. CA analysis showed that both the flavor and emotional factors were positive for seaweed & anchovy and topokki, but negative for red ginseng. As a result, seaweed & anchovy flavor, which is familiar to the Chinese people, should be the first cereal bar considered for a launch.

The purpose of this study is to investigate the patterns of Korean traditional food use in the households of middle aged women living in Kyunggido and Incheon area Four hundred eighty seven housewives whose children were in middle school answered the questionnaire about Korean traditional food use patterns in ordinary days, national festive days and in private celebration or memorial days. Most households have used Korean traditional table setting called Bansang as daily meals(96.7%) and have used home-made Kimchi(97.3%). However, the use of home-made Jang such as soy sauce, soybean paste and red pepper soybean paste was not very high(64.3%). Most households have celebrated New Years day(99.6%) with Ddukguk and Manduguk, Chusuk(95.1%) with Songpyun, and fruits, Full-Moon day(95.1%) with Ogokbap, Namul and Brum. Dongji was celebrated with Patjug by 73.3% of households. However, Samjitnal and Danho were celebrated with Whajeon and Ssukjulpyun by only 18.9% and 43.8% of the households respectively. The households using Korean traditional food to celebrate the birthday, the 1st birthday of child, the wedding or to memorize the passing day of ancestors were 96.0%, 80.7%, 81.3% and 86.7% respectively. Compared to households of urban and nuclear family, households of rural and extended family tended to use significantly more Korean traditional foods in many occasions and showed significantly higher rate of using home-made Kimchi and Jang.

Red pepper have affected traditional cuisines through various ways since they were first introduced in Korea over 400 years. But we on easily determine that red pepper powder and red pepper paste were not used daily dishes until 1940 as we look into traditional cookbooks. Chinese pepper and black pepper were used for hot spices before red pepper was introduced in Korea. It is estimated that red pepper was introduced during the last of 1500s the Japanese invasion of Chosun dynasty, but it was first used to make Sunchang red pepper paste in $\boxDr$Sumunsasul(수문사설)$\boxUl$(1740), and to make Kimchi in $\boxDr$Jeungbo Sanlimkungje(증보 산림경제)$\boxUl$(1766), and it became a general spice for vegetables in the middle of the 1800s. Pepper is mostly used to make Kochujang(red pepper paste), Kimchi, Jutkal(salted flesh) and Jangaji(salited very.) etc as fermentable cuisines. The attribute of using pepper was developed fur fermentable spices, and to give spicy flavor to cuisines. The types of peppers using traditional cuisines are various such as unripened pepper, red pepper, red pepper powder, red pepper paste, and pepper leaves. Traditional dishes with vegetables mostly use red peppers. Fish dishes(soup, stew, bracing, roasting, steaming) also use red peppers. Soup '||'&'||' stew with meat item partly use red pepper but steaming, roasting dishes with meat item not use pepper. roasted pork, pork ribs, steamed chicken of spicy meat cuisines in the 1930s did not use pepper. Kochujangbokkum(고추장볶음) is one of the oldest cuisines for using red pepper paste in the 1800s. Sliced red peppers and red pepper powder are mostly used for garnishing of cuisines.

초고압 공정(HPP)은 비가열 공정 중 하나로 식품 중의 세균 증식을 억제하는 방법으로 근래 들어 산업적으로 각광받고 있다. 현재 우유의 살균은 대부분 가열살균법에 의존하고 있으나, 가열살균은 우유의 영양소 및 이화학적 특성을 변화시키는 단점이 있다. 따라서 본 연구에서는 초고압 처리가 우유의 미생물학적 및 이화학적 특성에 미치는 영향을 알아보았다. 우유를 $15^{\circ}C$에서 600 MPa의 압력조건으로 3분간 처리했을 시 일반세균 및 유산균의 수는 2-3 Log CFU/ml 수준으로 감소하였으며, 대장균군은 HPP 처리 후 $4^{\circ}C$에서 15일 저장 기간 중에 검출되지 않았다. HPP 처리에 따른 유단백의 변성을 알아보고자 유단백의 전기영동 패턴을 분석한 결과, HPP 처리 우유가 가열살균 우유에 비하여 단백질 변성도가 낮게 나타났다. 또한 HPP 처리 우유의 경우 비타민 및 무기질의 함량 변화는 상대적으로 낮았으나, protease, lipase 및 alkaline phsophatase와 같은 우유 효소는 불활성화 시키는 특징을 나타내었다. 이러한 결과는 HPP가 우유의 영양소 파괴 및 이화학적 특성을 변화시키지 않으면서 우유의 미생물 제어에 사용될 수 있음을 제시한다.
