저온유통이 불가피하면서도 저장 가능 기간이 짧은 두부, 어묵 및 막걸리의 보존성 향상을 위하여 이들의 부패에 관여하는 균을 순수분리, 이들 균주틀 대상으로 각종 식용 식물의 에탄올 및 물 추출물의 향균 효과를 비교하였다. 두부와 막걸리 변질 관여균 모두에 황백 에탄올 추출물이 확실한 향균 효과틀 보였고 어묵의 경우는 황백, 정향, 오배자, 리기다, 백급 및 적작약 에탄을 추출물이 대상 균주 모두에 뚜렷한 항균성을 보였으며 에탄올 추출물이 물 추출물보다 높은 향균성을 나라내었다. 어묵 변질 관여균 모두는 황백 에란올 추출물의 첨가 농도에 따라 중식 저해를 받았으며 2000 ppm에서는 확실한 중식 저지 현상을 보였고 백급 에탄올 추출물은 한 균주에 대해서만 효과가 뚜렸하였다. 막걸리 변질 관여균은 황백 에탄을 추출물 1000 ppm 이상을 첨가시 2균주에서 뚜렷한 중식 억제 현상을 보였다.

This study was carried out to standardize the recipe of Gaeseong-Juak. The formation and quality of the Juak were investigated under different treatment conditions. 1. The high ratio of medium flour(20%) in the flour mixture resulted in poor swelling. 2. The flour mixture with 10% strong flour showed higher volume of Gaeseong-Juak compared with the 10% mixture of medium flour, but the score of sensory evaluation was low. 3. The addition of Makkoli in the dough did not give significant difference in the formation of Juak, but the sensory score was low. 4. The deep-frying temperature in the range of 150$\^{C}$ to 170$\^{C}$ allowed the greatest swelling of Gaeseong-Juak, but the highest quality score was obtained at 160$\^{C}$ treatment. Overall, the best preparation condition of Gaeseong-Juak was that the mixture of waxy rice flour with 10% medium flour was kneaded with Makkoli and fried at 160$\^{C}$.

Anaerobic fermentation using Clostridium butyricum NCIB 9576, and photo-fermentation using Rhodopseudomonas sphaeroides E15-1 were studied for the production of hydrogen from Makkoli, fruits (orange & apple, watermelon & melon) and Tofu wastewaters. From the Makkoli wastewater, which contained $0.94g/{\ell}$ sugars and $2.74g/{\ell}$ soluble starch, approximately $49mM\;H_2/{\ell}$ wastewater was produced during the initial 18h of the anaerobic fermentation with pH control between 6.5-7.0. Several organic acids such as butyric acid, acetic acid, propionic acid, lactic acid and ethanol were also produced. From Watemlelon and melon wastewater, which contained $43g/{\ell}$ sugars, generated about approximately $71mM\;H_2/{\ell}$ wastewater was produced during the initial 24 h of the anaerobic fermentation. Tofu wastewater, pH 6.5, containing $12.6g/{\ell}$ soluble starch and $0.74g/{\ell}$ sugars, generated about $30mM\;H_2/{\ell}$ wastewater, along with some organic acids, during the initial 24 h of anaerobic fermentation. Makkoli and Tofu wastewaters as substrates for the photo-fermentation by Rhodopseudomonas sphaeroides E15-1 produced approximately 37.9 and $22.2{\mu}M\;H_2/m{\ell}$ wastewaters, respectively for 9 days of incubation under the average of 9,000-10,000 lux illumination at the surface of reactor using tungsten halogen lamps. Orange and apple wastewater, which contained 93.4 g/l, produced approximately $13.1{\mu}M\;H_2/m{\ell}$ wastewater only for 2 days of photo-fermentation and the growth of Rhodopseudomonas sphaeroides E15-1 and hydrogen production were stopped.

The purpose of this study was to assess the consumption patterns of Makoli and to provide age-specific suggestions to increase the popularity of newly developed products. The subjects of the study were 373 men and 329 women, and information was obtained by self-administered questionnaire in December of 2010. One major finding of the study was that regardless of gender, consumption of Makoli was correlated to age: older respondents drank more Makoli. Those in their thirties and older, especially women, drank Makoli at home with family. The reasons given for liking or disliking Makoli differed among age groups, but were the same between genders. More subjects in their twenties liked Makoli because of its distinctive taste, while more in their forties liked it for its cultural value. Subjects in their thirties disliked it because it caused headaches, while more in their forties complained of burping. Both genders in their twenties suggested that TV and internet advertisements may be the best strategy to increase the popularity of newly developed Makoli products, and women in their forties suggested promoting Makoli's health benefits. The low calorie content of new Makoli products appealed to women of all age groups and men in their twenties and thirties. Women in their forties were also attracted by Makoli's possible effect to alleviate constipation.

유과제조에 좋은 특성을 갖는 일반계 찹쌀(품종： 신선)을 이용하여, 유과의 기업적 생산에 필요한 유과의 제조조건 및 팽화기작 추적 시험을 실시하였다. 유과 반데기 제조를 위한 증자시간은 증기가열로 5, 10, 15, 30, 45, 60분 처리에서 15분이 가장 적당하였고. 반죽의 수분함량은 48, 51, 53%를 시험한 결과, 48% 수준에서 조직이 가장 치밀하였다. 꽈리치는 시간은 1, 3, 4분간에 유의적인 차이가 없이 품질이 우수하나. 전혀 꽈리치기를 하지 않은 처리구는 조직의 치밀성이 낮고, 경도가 아주 유약하였다. 습식 및 건식제 분등 제분방법별 고온처리에 의한 공정단순화 시도에서 습식제분이 건식제분보다 팽화율이 높았으나, 고온처리 시간이 길어질수록 팽화율이 낮아졌고, 환원당량도 증가하여 전분의 분해가 이루어짐을 알 수 있었고. 이들이 유과의 팽화에 부정적인 영향을 주었으나. 각종 두류를 첨가한 결과 단백질 함량이 높아짐에 따라 유과특성이 개선되었다. 반데기는 장기저장시 RM에 따라 흡습정도가 달라졌고, 저장기간에 따라 팽화후 유과 바탕의 품질은 열화 되었다. 유과제조시 주류로서 막걸리, 소주, 청주를 각각 다른 양 첨가하여 품질을 비교한 결과, 첨가량이 중량비로 15%에서 30%로 증가함에 따라서 팽화율 및 조직특성이 다소 향상되었다.
