Effects of Takju(Korean turbid rice wine) lees on noodle investigated by substituting Takju lees water extract powder for each 2% and 4% wheat flour in sample II and III, respectively. The lightness(L) of uncooked noodles was decreased, whereas that of cooked noodles was increased with increasing amount of extract added. Redness(a) and difference of total color(${\Delta}$E) were significantly increased according to the amount of extract added in uncooked and cooked noodles. Yellowness(b) of the noodles containing 2% Takju lees water extract powder was exhibited lowest values in uncooked and cooked noodles. In cooking property of noodles, turbidity of soup decreased in proportion to amount of extract added, 2% and 4% in sample II and III, respectively whereas the weight and volume of noodles were not significant than those of control. Tension of cooked noodle was highest in sample II and lowest in sample III. Texture profile analysis of cooked noodle showed an significant increase of hardness in addition of Takju lees water extract powder but not significant different in springiness, chewiness, adhesiveness. Cohesiveness was significantly lowest in sample II. The sensory evaluation showed that significant difference between noodles with 2% addition groups and control was not recognized but was recognized 4%. Therefore, based on cooking properties and sensory evaluation, Takiu lees water extract powder up to 4% could be substituted for wheat flour.

Physicochemical and sensory characteristics of Yukwa(fried rice cookie) made by different processing condition were investigated to estabilish the optimum expansion of Yukwa. The expansion rate and crispness of Yukwa prepared by soaking waxy rice for 24 hours was satisfactory . Addition of 15% soy slurry gave better effect on increasing the expantion rate, crispiness and sensory preference than no addition of soy slurry . Yeast, Soju(distilled liquor) , Mackeali(rice wine, turbid) and Chunju(rice wine, clear) as expansion reagent were added to Yukwa prepration . Yeast and Mackeali among tested expansion reagent showed better expansion rate and lower hardness meausred by texturometer than Chunju. Yukwa added chungju showed more fine structure and lower expantion rate than others. Microwave puffed Yukwa was less expansion rate, but same level of crispiness and hardness compared with oil puffed. And no difference in sensory characteristics such as degree of crispiness and stickiness of microwave puffed and oil puffed.

This study was performed to determine the effect of Takju(Korean turbid rice wine) lees on the serum glucose level in streptozotocin-induced diabetic rats. 24 Sprague-Dawley male rats were divided into three groups: normal control(NC), diabetic control(DC) and diabetic rats(DS) were fed on experimental diet and water ad libitum for 4 weeks. DS diet was containing 20% Takju lees. Body weight gain and food Efficiency Ratio(FER) were significantly lower in DC and DS than NC. DS tended to have higher weight, weight gain and FEF than DC nevertheless food intake. Therefore Takju lees could possibly complement casein as a protein source. Gastrointestianl transit time in DS significantly decreased than NC while not significantly than DC. Serum lipid profiles and AST. ALT and amylase were not significantly different between diabetic DC and DS. Blood glucose was measured at fasting state and 30, 60, 90 and 120 minute by oral glucose tolerance test, DS tended to lower the mean(${\pm}$ SE) incremental blood glucose concentrations than DC and was significantly low at 120 min. But incremental AUG(area under the curve) of postprandial glucose response was not significantly different. In conclusion, in spite of high contents of carbohydrate Takju lees perhaps have a benefit effect on the diabetes.

Taurine contents in alcoholic and non alcoholic beverages, milk and milk products, sugars and condiments were determined for 83 food items commonly used by Koreans. Taurine concentrations of food samples were analyzed by using an automated amino acid analyzer(Biochrom 20, Pharmacia LKB) based on ion exchange chromatography. Taurine was not detected in most carbonated beverages, but found in a variety of fruit and vegetable beverages(canned) in the range of 0.13 ~1.43mg taurine/ 100g wt, and in instant coffee or tea beverages(canned) in the range of 0.10~0.41mg taurine/100g wt. The traditional Korean turbid rice wine(takju) sample contained the highest level of taurine (2.29mg/100g wt) among alcoholic beverages tested, which was followed by wine(0.59~0.88mg tau rine/100g wt) and beer(0.53~0.73mg taurine/100g wt). Ordinary milk samples contained 1.05~1.40 mg taurine/100g wt, and a variety of taurine supplemented infant formulas manufactured by Korean companies included 17.3~25.4mg taurine/100g wt. Taurine was not detected in most sugars and sweetners except a couple of chocolate samples(2.13~2.18mg taurine/100g wt). Exceptionally high level of taurine was found in a curry powder sample(16.9mg taurine/100g wt), while the rest of commonly used condiments contained less than 2.90mg taurine/100g wt.

유과 품질향상을 위한 몇 가지 첨가물의 효과와 공정개선을 위한 수침시간 단축 및 쌀가루에 의한 유과제조 시험을 수행하였다. 불린 콩을 첨가(3%, w/w)한 유과는 팽화도가 높았고 물리적 조직특성도 우수하였으며 관능검사 결과도 이들 경향과 일치하였으나 baking powder, 변형녹말과 막걸리, 소주, 청주 등 주류는 첨가효과가 인정되지 않았다. 그러나 주류는 유과의 외형적인 조직이 치밀해지는 경향을 보였다. 쌀전분의 호화근접 온도인 $60^{\circ}C$의 고온수침에서 3시간 정도면 충분한 수화가 이루어져 저온 장시간($12{\sim}14$시간) 수침한 경우와 차이가 없었으며 고온수침시간의 연장(12시간)에서는 품질개선 효과가 인정되기 않았다. 그리고 건식제분한 쌀가루로 유과를 만드는 경우 100mesh가 팽화도 및 경도에서 우수하였으나 습식제분보다 품질이 떨어져 제분방법과 제분기의 별도연구가 필요하였다.

유럽에서 지리적 표시제도는 약 100여 년 전부터 도입되었던 것과는 달리 우리나라에서의 지리적 표시제도는 보편적이지 않은 개념이다. 최근 들어서야 지리적 표시제도에 대한 연구가 진행되고 있으나, 국내 도입이나 활성화 방안에 대한 학술적 논의는 부족한 실정이다. 지리적 표시제도는 지역 활성화, 소비자보호, 경제효율성 측면에서 장점이 있다. 더욱이 우리나라의 농수산물이 유럽에 비해 지리적표시를 통해 보호해야할만한 가치가 부족한 것도 아니다. 이에 지리적 표시제도 선진국들의 사례를 면밀히 검토하여 우리나라에도 지리적 표시제도를 정착시켜야 필요가 있다. 본 연구에서는 지리적 표시제도의 현황과 해외의 전통술 보호를 위한 지리적 표시제도 활용 정책에 대해 살펴본다. 프랑스는 와인, 일본은 사케, 독일은 맥주와 같이 한 나라를 대표하는 술이 세계적으로 사랑을 받고 있는 것처럼 우리나라의 막걸리 또한 지리적 표시제도를 활용하여 막걸리산업의 성장을 이룰 수 있는 방안을 제시하고자 한다.

This study was conducted to investigate the effects of Takju lees hot water extracts on the blood pressure in spontaneously hypertension rats (SHR). Twenty eight male SHR were grouped by their blood pressure and fed a control diet or experimental diets containing 1% (G1), 2% (G2), or 4% (G4) Takju lees extracts for 4 weeks. Food intake was not significantly different among the groups. However, body weight gain was significantly lower in groups fed the Takju lees extract than the control group. The systolic blood pressure was significantly lower in the Takju lees extract containing groups (especially in G4 group) than the control groups. In addition, mean blood pressure {(systolic+dyastolic)/2} decreased with an increase in the amount of Takju lees extract in the diet and feeding period. Takju lees extract decreased angiotensin I converting enzyme (ACE) activity in a dose-dependent manner. These results suggest that the Takju lees extract exert an antihypertensive effect by decreasing ACE activity.

We investigated the effect of Takju lees extract on blood glucose levels in the db/db mice (a murine model of type 2 diabetes mellitus). We fed 40 male db/db mice a control diet (G0, AIN93G) and experimental diets containing 1% (G1), 2% (G2), or 4% (G4) Takju lees extract for 4 weeks. We found no difference in food intake and body weight gain among the animal groups. In the G1 and G2 groups, plasma glucose levels decreased significantly between Days 10 and 21 compared with the G0 group. However, we found no difference in plasma glucose levels between groups G4 and G0. The change in insulin concentrations was not significant among these animal groups, and we found no significant difference in glucose transporter 4 (GLUT4) expression in the soleus muscle. These results suggest that the Takju lees extract has a beneficial effect in animals with type 2 diabetes.

Takju lees extract is expected to be a promising material for functional food. This study was conducted in order to assess the glycemic index (GI) of Takju lees extract and its effects in an oral glucose tolerance test (OGTT). The GI for Takju lees extract was evaluated with 10 healthy young adults (Male 5, Female 5). OGTT was conducted in 20 male db/db mice, fed on a diet containing 2% Takju lees extract for 4 weeks. Those animals were subjected to OGTT after one oral administration of Takju lees extract at 2 g/kg BW. The GI of the Takju lees extract was measured at 97.97. The effects of the Takju lees extract on the oral glucose tolerance test in db/db mice evidenced no differences as compared to the control group. In conclusion, Takju lees extract is a high GI material, and it has no effect on blood glucose levels in a type II diabetic animal model. Further studies will be required to confirm its anti-diabetic effects.
