To examine enzymatic browning of apple wine, changes of active bands of polyphenol oxidase (EC 1.10.3.1) as well as polyphenol substances related to browning of apple wine were investigated during wine brewing. The decrease of total phenol was remarkably inhibited by the addition of sodium metabisulfite. In the meantime, auto-oxidation of catechol in a model system increased proportionally as the reaction pH and temperature increased. Catechol oxidation, however, was not detected at $4^{\circ}C$ below pH 5.0. Polyacrylamidegel electrophoretic patterns showed that the apple (Jonathan) indicated 4 bands with polyphenol oxidase activity, designated a, b, c and d whose Rm were 0.21, 0.30, 0.41 and 0.51, respectively. Among these, 2 bands, a and c remained until 5th day fermentation and only c band after 6th day fermentation. After pasteurization of apple wine at $60^{\circ}C$ for 30min, c band also remained.

Objective : The purpose of this study is not only to examine the negative functions of alcohol, but also to examine the positive functions and look at it with a balanced perspective. Methods : We investigated the number of times the word "酒"(alcohol) appears in 《Hwangjenaegyeong》 and 《Gyeongakjeonseo》. The meaning of alcohol was divided into seven categories. The number of positive and negative functions of alcohol was counted and the ratio was calculated. Results : 1. In the 《Hwangjenaegyeong》, the word alcohol appears 23 times, of which 9 times has positive functions, 10 times has negative functions, and the remaining 4 times does not correspond anywhere. The ratio of positive functions is 39.13% and negative functions 43.48%. 2. In the 《Gyeongakjeonseo》, the word alcohol appears 1,487 times, of which 1,140 times (76.66%) has positive functions, and 327 times (21.99%) has negative functions. Conclusions : 1. In 《Hwangjenaegyeong》, the number of comments about positive and negative functions of alcohol is similar. 2. 《Gyeongakjeonseo》 has commented a lot about the positive functions of alcohol. However, it has more mentions to negative functions of alcohol except for those related to herbs and prescriptions (48 to 64 chapter). 3. It is somewhat unreasonable to judge the emphasis on the positive and negative function of alcohol according to the number of references to alcohol in oriental medicine classics. But in these books, we can find a balanced approach between the two sides, not a one-sided biased view. 4. From a curative point of view, it is desirable to know and to use the positive and negative functions of alcohol, and drink alcohol as appropriate control.

Extensive selection works on wild yeasts of fruits were carried cut to obtain strains which are applicable to apple wine making. Among the total number of 1,358 yeast strains which were isolated from various fruit samples collected from the vicinity of Daejeon and other regions cf Korea, the strains SH-49, SH-129 and SH-338 were found to be useful. Then experiments on their morphological and physiological characteristics, and on the aspects of practical use in apple wine making were proceeded. The results obtained were as follows: 1. The strains SH-49 and SH-129, particularly SH-49, were appeared to have good fermentation ability, tolerance to sulfur dioxide and to produce fine quality of apple wine. 2. Apple wines made by using the strain, SH-49 and SH-129 contained less amount of total acids than those by other strains. 3. Apple wines of SH-49 and SH-129 were clarified rapidly during the primary fermentation period, and their absorbancy at 430 nm after 45 days of storage were approximately half of others. 4. Apple wine of SH-338 contained higher amount of residual sugar and its quality was superior to others. It is considered that this strain could be used in the production of apple wine of a characteristic quality. 5. The strains SH-49 and SH-338 were identified as a Saccharomyces cerevisiae according to Taxanomic Study of Yeasts by Lodder, however, classification of SH-129 was suspended for further study.

Baikhaju, Nockpaju, Dongdongju and Chungmyungju of the traditional Yakjus - the native alcoholic beverage of Korea - with the different fermentation methods were brewed and the volatile odor components were analized by gas chromatography methods of headspace gas. The general constituent content in them was different a little, and formaldehyde, acetone, acetaldehyde, ethylacetate, ethylalcohol, n-propanol, iso-butanol, iso-amylalcohol, diacetyl and dimethyl sulfide were separated and quantified into the volatile aroma components. The contents of acetaldehyde, ethylacetate and n-propanol were $17{\sim}73ppm$, and iso-amylalcohol were $418{\sim}925ppm$. The contents of formaldehyde and acetone were $0{\sim}2.15ppm$, and that of diacetyl and dimethyl sulfide were $0.032{\sim}1.012ppm$, and $5{\sim}65ppb$.

Acorn wine was manufactured experimentally with koji inoculated the strain producing acorn tannin hydrolyzing enzyme in order to apply fungal tannase to food processing. Starch value of several Korean acorns was found to be 72.84 and the acorns were worthy of use as a carbohydrate food. Mixed koji was prepared by combination of rice and acorn powder at a ratio of 50to 50 and inoculation of Aspergillus oryzae producing amylase and Aspergillus sp. AN-11 producing tannase into the mixture in order to hydrolyze efficiently acorn tannin inhibiting alcohol fermentation in the medium, and then the mixed koji was used as a suitable koji to manufacture acorn wine. Acorn wine brewed with medium of the acorn powder treated with water and cooked and the mixed koji prepared was superior about two times to that brewed with medium of untreated acorn powder and general koji with respect to the rate of alcohol production and sugar fermentation during the 1st and 2nd brewing.

우리 민족(民族)의 희노애락(喜怒哀樂)과 함께 흘러온 민속주(民俗酒)는 우리의 문화(文化)와 더불어 발전(發展)되어 왔었다. 그러나 일본(日本)의 지배(支配)를 받게된 이후(以後)에는 대부분의 민속주(民俗酒)는 밀주(密酒)로 규정(規定)되어 주조(酒造)가 금지되어 왔으며 해방후(解放後)에도 한국정부(韓國政府)의 양곡정책(糧穀政策)으로 인하여 특히 1961년(年) 이후(以後)에는 쌀을 사용하는 민속주(民俗酒)는 강력(强力)하게 금지(禁止)되었고 민속주(民俗酒)에 관(關)한 문화(文化)는 거의 자취를 감추게 되어 왔었다. 그런데 다행(多幸)히도 1985년(年)에 문공부(文公部)에서 민속주(民俗酒)의 주조(酒造) 기술(技術)을 가진 많은 기능인(機能人)을 문화재보호(文化財保護)의 차원(次元)에서 발굴(發掘)하였고 그 기능(機能)을 보존(保存) 계승(繼承)하도록 노력하였다. 따라서 정부(政府)에서는 1988년(年) 9월(月) 전통(傳統)과 기술(技術)이 인정(認定)되는 24종(種)이 민속주(民俗酒)를 민간인(民間人)에게 주조(酒造)할 수 있도록 예비(豫備) 가능(可能)한 바 있었다. 그 24종(種)의 민속주(民俗酒) 중(中)에서 한산(韓山) 소곡주(素穀酒), 경주(慶州) 법주(法酒), 천(川) 박시주(朴?酒), 안동(安東) 소주(燒酒), 이리 이강주(梨薑酒)에 관(關)하여 그 유래(由來), 특징(特徵), 전승(傳承)의 근원, 제조현황(製造現況) 그리고 전래(傳來)된 일화(逸話) 등을 조사(調査) 수록(收錄)하였다.

술! 우리 주변에서 쉽게 접할 수 있는 술. 이 술이라는 말에는 어떤 뜻이 내포되어 있을까? 현재 우리가 사용하고 있는 술이라는 말은 본래 '수불'이라고 불렸다고 한다. 물과 불! 우리 선조들은 술을 빚는 과정에서 효모가 생성하는 이산화탄소에 의해 술덧(술밑) 표면에 거품이 생기는 현상을 보고는 물에 불이 붙어서 부글부글 끓어오르는 것으로 생각하고 '수불'이라고 표현한 것 같다. 어찌 보면 비약적인 해석일 수 있으나 우리 선조들이 말 속에 과학 현상을 잘 표현한 것이라 할 수도 있다. 술의 한자어인 주(酒)는 물 수(水)자와 본래 술을 뜻하는 유(酉)자가 합쳐진 것으로 '물이 익은 것' 이라는 뜻이 내포되어 술이 만들어지는 현상을 표현한 것이라면, 술이라는 말은 효모에 의해 술이 만들어지는 과정의 일부를 과학적으로 표현한 말이라고 할 수 있다. 또 이 말 속에는 끓는다는 뜻의 라틴어 'ferverve'에서 유래된 'fermentation', 즉 발효의 의미도 포함되어 있다. 이러한 뜻을 내포하고 있는 술에 대해 우리나라 주세법에서는 알코올 도수 1% 이상의 음용 가능한 것이라고 정의하고 있으나, 각각의 개인이 내리는 술에 대한 정의는 천차만별일 것이다.

Film-formation, which often occurs during storage of apple wine, owing to contamination by film-forming yeasts, results in inferior products. Therefore, for the purpose of preventing this occurrence, we isolated and identified yeast strain. Among the total number of 45 yeast strains which were isolated from contaminated apple wine in winery, the strains FY-4 and FY-5 were found to be useful. The strain FY-5, which greatly formed film on apple wine, was identified as Hansenula beijerinckii or similar strain according to taxonomic characteristics.
