본 연구를 통해서 부추와 마늘의 생즙과 가루의 항균활성은 농도의존적으로 증가되어짐을 확인할 수 있었고, 그람음성균인 Escherichia coli, Salmonella enteritidis 보다 그람양성균인 Staphylococcus aureus 에 대한 항균력이 높음을 알 수 있었다. 부추는 생즙에 비해 가루의 항균활성이 떨어졌고, 마늘은 생즙과 가루의 활성이 유사하게 분석됨으로써, 냉동건조 후에도 항균활성이 유지됨을 확인할 수 있었다. 부추와 마늘간의 항균활성을 비교해보면, 생즙과 가루 형태에서 모두 부추보다 마늘의 항균활성이 높게 나타났다. 부추와 마늘 모두 항균활성 온도가 높을수록, 가열 시간이 길어질수록 저하되었고, 마늘가루가 부추가루보다 약한 열 안정성을 보였다. 또한 부추와 마늘 모두 pH에 따른 항균성의 변화는 일정하게 유지되어 pH 변화에 대해서는 비교적 안정한 것으로 나타났다. 부추와 마늘생즙, 부추와 마늘가루의 혼합 비율에 따른 항균성의 변화는 마늘비율의 증가에 따른 효과가 나타날 뿐, 시료간 혼합에 따른 상승효과는 나타나지 않았다. 또한 부추와 마늘가루는 복합균주에서 각각의 균주에 대해여 항균활성을 나타내었으며, 이는 단일균주에 나타난 항균활성과 유사한 것으로 나타났다.

Commonly used spices in Korean cooking (red pepper powder, garlic, ginger) were evaluated for anti-obesity properties and effects on triglyceride (TG) and cholesterol in blood and adipose tissues in rats fed a high fat (20%) diet. SD rats were raised for four weeks on either a normal diet (ND, based on the AIN-93M diet), high fat diet (HFD, supplemented with 16% lard oil in the ND), or diets containing 5% red pepper powder (RPP), garlic or ginger. These spices significantly decreased weight gain compared to HFD, but garlic and ginger showed a greater effect on reducing weight gain than RPP. The weights of liver and epididymal and perirenal fat pads in garlic and ginger diet groups were lower than those of the HFD groups (p < 0.05). The garlic and ginger also decreased triglyceride and cholesterol contents in liver and epididymal and perirenal fat pad, reversing the higher levels seen in HFD. RPP, garlic and ginger supplemented diets were effective in lowering serum triglyceride and cholesterol levels (p< 0.05). These results indicated that garlic and ginger more effectively suppressed the effects of HFD on body fat gain and lipid values of adipose tissues and serum than RPP.

본 연구에서는 동맥경화의 원인으로 알려진 사람 low density lipoprotein (LDL)에 대한 garlic oil의 산화억제 효과에 대하여 실험하였다. Garlic oil을 HPLC로 분석한 결과 diallyl disulfide, diallyltrisulfide, diallyltetrasulfide and diallyl pentasulfide 등의 유황화합물이 많이 들어 있었다. 사람 LDL을 $Cu^{2+}$ 및 macrophages 유도 oxidized LDL로 산화시킬 때 garlic oil을 20~60${\mu}g$/mL 범위에서 첨가하며 실험하였을 때 용량 의존형으로 억제되었고, garlic oil을 60 ${\mu}g$/mL 첨가하였을 때 LDL의 산화가 거의 억제되었으며, 산화 LDL의 전기영동에 의한 이동거리도 60 ${\mu}g$/mL 농도에서 거의 억제되었다. 그리고 garlic oil은 동맥의 내피세포에서도 용량 의존형으로 억제효과를 나타내었다. 또한 garlic oil은 tocopherol, ascorbic acid 보다 약간 높은 억제효과를 나타내었다. 이상의 결과에 따르면 garlic oil은 macrophage 및 내피세포에서 LDL의 항산화 효과가 있어 LDL의 산화 억제효과가 있는 것으로 나타났다.

This study was conducted to evaluate the functionality of fermented black garlic extracts under various conditions. Black garlic powder was prepared by aging for 0~72 hours at 80℃ depending on relative humidity (RH). It showed the highest antioxidant effects among the samples; the total antioxidant activity of black garlic powders at RH 75%, 84%, and 90% for 72 hours was increased 31.9 times, 28.2 times, and 22.6 times compared with that of the fresh garlic powder, respectively. Also, the alliin content was gradually decreased. S-ally-L-cysteine and S-ethyl-cysteine levels were increased; the highest values were 495.9 ㎍/g and 1,769.7 ㎍/g after aging for 72 hours at RH 75%. Aspartate transaminase (AST) and alanine transaminase (ALT) levels were increased following high fat diet feeding, but the rise was obviously reduced by administration of black garlic extract. The total cholesterol, LDL/VLDL-cholesterol, and triglyceride contents in serum were significantly lower in methionine and choline deficient (MCD) diet treatment groups than in the positive control group. The concentration was increased following the intake of black garlic and fermented black garlic extracts. Therefore, black garlic extracts could be an ideal material as a dietary supplement in healthy functional foods to improve the effects on fatty liver.

마늘과 대두배아의 발효물을 반응시켜 allithiamine의 함량이 기존의 마늘에 비해 6배 증가한 바이오갈릭을 제조하였다. 바이오갈릭이 고지방 식이에 의해 유발되는 과체중 및 고지혈증에 미치는 영향을 조사하기 위하여 고지방에 1%의 바이오 갈릭이 포함된 식이를 제조하고 이를 흰쥐에 8주간 공급하였다. 바이오갈릭은 흰쥐의 식이 섭취량에는 영향을 끼치지 않았으나 체중의 증가 정도를 유의적으로 억제하였다. 또한 혈중 총콜레스테롤 및 중성지방의 수준을 저하시켰으며, HDL-콜레스테롤의 수준을 증가시키는 효과를 나타내었다. 이와 같이 바이오갈릭에는 동맥경화지수를 감소시키는 생리활성이 있는 것을 알 수 있었으며 향후 혈행개선 효과를 갖는 건강 지향적 식품소재로서의 사용에 대한 가능성이 있음을 확인할 수 있었다.

Anticarcinogenic effects of garlic juice were studied in hamsters exposed to 9,10-dimethyl-1, 2-benzan-thracene in their buccal pouches. The distribution of nodule quantity and size was recorded among different groups of hamster. The results show that nodule formation was suppressed in hamsters which were fed with garlic juice compared to hamsters which were not. The average nodule volume was 81.10㎣ for hamsters fed with 3% garlic juice and 181.26㎣ for hamsters without garlic in their diet after 90 days of treatment.

The purpose of this study was to investigate the effects of garlic, soy protein and taurine on blood lipid profiles in postmenopausal hyperlipidemic model rats. Seventy-two female Sprague-Dawley rats weighing 200g were fed a commercial diet for one week. All rats were ovariectomized and then were randomly assigned to eight groups (high fat diet group; HFD group, 2% garlic powder group; GP group, taurine group; TR group, soy protein group; SP group, 2% garlic powder ＋ taurine group; GP＋TR group, 2% garlic powder+ soy protein group; GP＋SP group, taurine＋soy protein group; TR＋SP group, 2% garlic powder＋taurine＋soy protein group; GP＋TR＋SP group).(omitted)

The objectives of this study were to identify the pickled garlic's attributes and verify the structural relationships among the attributes, customer satisfaction, and intention of repurchase. In order to achieve the purpose of this study, literature review and empirical study were used. As the results of this research are as follows. A majority of respondents answered that they preferred pickled garlic with soy sauce. And they were down on the lack of variety in pickled garlic products and garlic recipes. The nutrition facts and the value of producer of pickled garlic were verified to examine the effects on consumer satisfaction and intention of repurchase.

Garlic is an important condimental vegetable which has many minerals and numerous organic sulfur compounds. Owing to these components, garlic has many medicinal properties and physiological activities on human health. It can lower sect lipid levels and reduce the severity of cholesterol-induced atherosclerosis. And it appeals to protect against mutagenic and carcinogenic effects. Today's our eating habit is concentrated on the physiological function in floods rather than their taste or mutagenic. To improve garlic's value as a flood or a vegetable, further scientific researches about its volatile and nonvolatile sulfur compounds through the biochemical approach are needed. In addition to that, both areas that the development of garlic-processed goods and utilization of garlic as materials for medicine must be actively studied.

Effects of various concentrations of garlic powder and garlic extract in the diets on growth, serum chemistry and immune response of olive flounder were determined. Thirty-five juvenile fish averaging 5.1 g were randomly distributed into 21 of 180 L flow-through tanks. Seven experimental diets with various concentrations of garlic powder (GP) and garlic extract (GE) were prepared in triplicate: GP-0 without garlic supplementation, GP-0.5, GP-1, GP-2, GP-3 and GP-5 diets containing garlic powder at the concentrations of 0.5, 1, 2, 3 and 5%, respectively at the expense of wheat flour and finally, GE-0.4 diet containing 0.4% garlic extract were prepared. At the end of the 8-week feeding trial, serum chemistry of fish was measured. In addition, twenty fish from each tank were artificially infected with E. tarda for the following 96 h to monitor cumulative mortality. Weight gain of fish fed GP-0 diet was higher than that of fish fed GP-1, GP-2, GP-3 and GP-5 diets. No difference in serum criteria (total protein, glucose, glutamate oxaloacetate transaminase, cholesterol and triglyceride levels) of olive flounder was found among the experimental diets except for glutamate pyruvate transaminase. Lysozyme activity of fish fed GP-0, GP-1, GP-3 and GE-0.4 diets was higher than that of fish fed GP-5 diet. The highest cumulative mortality was 93.3% in fish fed GP-0 diet at 96 h after E. tarda infection, followed by GP-3, GP-1, GP-5, GP-2, GP-0.5 and GE-0.4 diets. In considering these results, dietary inclusion of garlic powder and garlic extract has no distinctive positive effect on improvement in growth, serum chemistry and immune response of olive flounder in this experimental conditions, therefore, its application should be carefully considered.
