본 연구는 건조 오미자 추출액을 이용하여 오미자 식초를 발효하였다. 산패한 오미자 와인에서 식초산균 OV1과 OV2를 분리하고 분리균의 식초산 생성능력을 비교하였다. 분리균 OV1은 알코올농도 8%까지 발효 가능하였으며, 알코올 농도 6%의 오미자 와인으로부터 산도 5.21%의 식초를 발효하였다. 발효 오미자 식초는 시판 중인 타 식초에 비하여 관능성이 보다 우수한 것으로 평가되었다. 오미자 와인 및 식초의 항균력을 paper disc법으로 검정한 결과 식초는 4종의 검정균(B. subtilis, S. aureus, E. coli 및 P. fluorescens)에 대하여 직경 9.5~17.00 mm의 clear zone을 형성한 반면에 오미자 와인은 S. aureus와 P. fluorescens에 대해서만 clear zone을 생성하였고 clear zone의 직경 또한 9.5 mm 이하로 추출물과 비슷하였다. 오미자 와인 및 오미자 식초의 DPPH free radical 소거능은 오미자 와인(80배수)이 70.25%로 발효 전 추출액에 비하여 약 1.6배 증가하였으나 오미자 식초는 추출액과 비슷한 수준이었으며, 아질산염 소거능 또한 와인에서 높고 식초에서 낮아지는 경향을 나타내었다. 이상의 결과로부터 보당한 건조 오미자 추출액을 사용하여 기호성과 기능성을 갖춘 고품질의 식초를 제조할 수 있는 것으로 판단된다.

홍삼 특유의 prosapogenin 성분을 극대화 시키기 위해 홍삼의 증숙, 건조 및 추출 공정을 최적화하여 식초에 첨가할 홍삼 농축액을 제조하였다. 농축액을 0-1%의 범위로 첨가한 홍삼 발효 쌀 식초의 경우 정치 배양 20일차에 초산발효가 종료 되었으며 홍삼 농축액의 함유량이 높을수록 pH 감소속도가 늦고 감소량 또한 control에 비해 적음을 확인 할 수 있었다. 산도의 경우 농축액 농도 별 초산 생성 속도에는 차이는 있으나 농축액 함유량이 산도 변화 량에 큰 영향을 미치지 않았다. 1%의 홍삼 농축액을 후 첨가한 식초의 경우 71.75 mg/g의 조사포닌 함량을 가진 반면에 0-1% 범위의 농축액을 주모에 첨가하여 초산 발효를 동시에 진행한 경우 발효 진행 중 상당한 조사포닌 손실이 있음을 확인하였다. 이 두 식초를 가지고 관능검사를 진행한 결과 향기, 맛 및 전체적인 평가에서 농축액과 초산발효를 동시에 진행시킨 홍삼발효식초가 더 좋은 선호도를 나타내었다.

자연발효식초로부터 acetic acid 생성능이 우수한 10종의 균주를 분리한 후 에탄올 저항성과 아황산 저항성을 평가하였고, 16S rRNA 염기서열을 분석하여 균주를 동정한 다음 명명하였다. 분리 동정된 10종의 균주 중 식품원료 사용 가능 균주인 Acetobacter pasteurianus는 8종으로 확인되었다. A. pasteurianus 8종 중 에탄올 저항성이 우수한 JAC002, JAC005, JAC008의 세 균주를 이용하여 막걸리 종초를 제조하였다. 진탕배양($30^{\circ}C$, 120 rpm) 조건에서 20일 동안 발효시키면서 막걸리 종초의 이화학적 특성, 유리당과 유기산의 변화, 유해균에 대한 항균 활성을 측정하였다. 선발 균주 중 A. pasteurianus JAC002 균주는 발효 20일 경과 후 총산도 4.21%, acetic acid 함량 3,791.77 mg%, 에탄올 소모량 2,931.78 mg%로 대조구나 다른 초산균에 비해 에탄올의 acetic acid 전환능이 우수하였다. 식품유해 지표균인 Staphylococcus aureus(KACC1927)와 Escherichia coli(KACC 10115)에 대한 항균 활성은 A. pasteurianus JAC002 균주가 접종된 막걸리 종초의 발효기간이 20일까지 경과했을 때 acetic acid 농도의 증가와 더불어 유의적으로 증가하는 것으로 확인되었다. 특히 A. pasteurianus JAC002 균주를 막걸리 종초 제조를 위한 종균으로 사용하였을 때 acetic acid 생성능이 우수하여 우점화가 유리하며 에탄올로부터 acetic acid로의 전환율이 높은 것으로 확인되었다. 따라서 이 막걸리 종초를 사용하여 다양한 원료의 식초를 제조한다면 식초의 풍미를 유지하면서 기능성을 증대시킬 것으로 기대된다.

Eumsikjeoljo (integrity with food) originally came from the Andong district, where the Goseong Yi clan inherited a cookbook from their ancestor Lee Jeong-Rong (1798~1871). The cookbook was written in an antiquated style and is estimated to have been written around the year 1865. Details of the era and authorship are seldom available for the extant ancient cookbooks. The authors of these books and the period during which these books were precisely written were studied through the Eumsikjeoljo which is a repository of 46 cooking disciplines. Of these 10 deal with the practice of traditional Korean crispy snack making, 4 with rice cake making, 3 of the yeonbyeong kind, 19 examples of Korean side dish making, 6 recipes of the kimchi variety, 2 examples of paste-based recipes, and 2 instances of instructions on how to make vinegar-based extracts. Also, in Eumsikjeoljo, there are descriptions of 29 different ways to brew rice wine. Of these, Danyang wine among the Leehwa wines and 13 others account for over 44% of the content. Leeyang wine and Sogok wine are represented by 10 different varieties and constitute around 34% of the entries. Samyang wine and Baek-il wine, along with 6 others, constitute 21% of the entries. The secret recipes of the Goseong Yi clan in the Andong district were recorded so that they could be transferred to the descendants of the clan. An inspection of the recipes and wine brewing techniques recorded in Eumsikjeoljo provides a clearer picture of the mid-1800s Andong noble family's traditional food habits and simultaneously sheds light on the late Joseon dynasty's food culture.

The Gwugonsiuebang is a book of Korean woman's life in the Yi dynasty which published I 1653 by Mme. Jang. I have studied the food habits of the Yi dynasty that wrote in Gwugonsiueband as following. The staple foods are Guksu (wheat vemicell as like western noodles) 5, Mandu (bun stuffed with seasoned meat and vegetables) 6 kinds in this book. the side dishes are Guk (soup) 8, J'm (steamed meat or fish) 6, chae6, Nooruemi 5, Hyae (sliced raw fish) 3, Jockpyun (jellied beef soup) 3, Jockgall (salted sea food) 2, Jock (skewer or broach) 2, jihee 2, Sun (Steaming of stuffed vegetable) 1, Bockuem (saute) 1, Jon (pan fried fish) 1, Gui (meat or fish grilled with seasoning) 1, and the other 13 kinds. The desserts are D,ock (Korean rice cake) 11, jabgwa 8, Beverages 5 kinds and Jungwa 1 kind. The alcohol and fruits wine are 51 kinds. The alcohol and fruits wine are 51 kinds. The seasonings are Soybean sauce, oil, Sesamol oil, pepper, Ginger, Garlic, Vinegar, Wine, Salt, Bean paste etc. Raw materials of Guksu, Mandu, D'ock, Jabgwa, Beverage, Wine, vinegar are all carbohydrates. It shows that a tendency of Korean people too much take a carbohydrates. Now and then, there are no special difference of winter over pass for vegetables, fruits, dried beef, dried fish and salt fishes. In yi dynasty, there are 62 kinds of table ware and cooking kitchen utensils, but many of them come to uselessness. 19 kinds of measuring unit are very non-scientific because that is not by weight but by bulk or volume. There are many food making terms which are 198 kinds of prepared cooking term, 11 kinds of cutting term and 20 kinds of boiling term. And 10 kinds of expression of taste can see this book.

A new strain of acidophilic, acetogenic bacterium, Acetobacter sp. strain HA was isolated by selective enrichment from the traditionally fermented rice wine vinegar in Korea. It was a gram-negative, non-motile short rod and oxidized acetate and lactate. The optimal temperature and pH for growth were $28^{\circ}C$ and 4.0, respectively. The strain HA differed from other Acetobacter species by growing well on methanol, xylitol, inositol, dulcitol, D-xylose, L-arabinose, and D-mannose as sole sources of carbon and energy. The isolated strain HA did not produce $\gamma$-pyrones from glucose and did not produce ketone bodies from glycerol. The quinone system used in this study was an ubiquinone-9 isoprene unit. The guanine-plus-cytosine content of the DNA was 50.7 mol%, and the major cellular fatty acids were $C_{18:1} and C_{16:0}$.

Two strains were isolated from the vinegar of Korean traditional fermented rice wine and the vine gar of fermented persimmon, respectively. These strains, designated as KM and BPV, were identified as the genus Acetobacter with respect to morphological, physiological, and biochemical characteristics. The Isolates oxidized ethanol to acetate and over-oxidized acetate or lactate to CO2 and H2O. They were positive in catalase test, while being negative in oxidase, gelatin liquefaction, VP test, H2O production and indole formation tests. No ${\gamma}$-pyrones ware produced from glucose and fructose. KM was tolerant of 11% ethanol while BPV was relatively sensitive to ethanol at a higher concentration than 5%. The guanine-plus-cytosine contents of the DNA of KM and BPV strains were 53.8 and 56.6 mol%, respectively. The cellular fatty acid compositions contained in these isolates were saturated straightchain C14:0 and C16:0,, and unsaturated straight-chain C18:1. Major ubiquinone system of KM was Q-9, but that of BPV was Q-10. In morphophysiological and biochemical aspects, KM strain was similar to Acetobacter pasteurianus. However, BPV strain was different from other Acetobacter type strains.

Elephant garlic (Allium ampeloprasum var. ampeloprasum), which belongs to the Alliaceae family along with onion and garlic, has a flavor and shape similar to those of normal garlic but is not true garlic. Additionally, its properties are largely unknown, and its processing and product development have not been reported. In this study, we focused on using elephant garlic to produce a new type of vinegar, for which the market is rapidly growing because of its health benefits. First, we evaluated the effects of elephant garlic addition on acetic acid fermentation of rice wine by Acetobacter pasteurianus. In contrast to normal garlic, for which 2% (w/v) addition completely halted fermentation, addition of elephant garlic enabled slow but successful fermentation of ethanol to acetic acid. Metabolite analysis suggested that sulfur-containing volatile compounds were less abundant in elephant garlic than in normal garlic; these volatile compounds may be responsible for inhibiting acetic acid fermentation. After acetic acid fermentation, vinegar with elephant garlic did not have any sulfur-containing volatile compounds, which could positively contribute to the vinegar flavor. Moreover, the amino acid profile of the vinegar suggested that nutritional and sensory properties were more enhanced following addition of elephant garlic. Thus, elephant garlic may have applications in the development of a new vinegar product with improved flavor and quality and potential health benefits.
