Purpose: The central composition design was used to optimize the mixture conditions of black garlic extract. Methods: The response surface methodology (RSM) was carried out from concentration of black garlic extract ($X_1$) and the amount of the black garlic extract ($X_2$) as independent variables, and salts ($Y_1$), reducing sugars ($Y_2$), the content of total phenolic compounds ($Y_3$) and ABTS radical scavenging activity ($Y_4$) as dependent variables. We confirmed the conditions that salinity was minimized and reducing sugar, total phenolic compounds and ABTS radical scavenging activity had maximum values through the response surface analysis. Results: All results had saddle points in originally set up conditions hence, ridge analysis was carried out for narrowing the experimental area. The minimum salt concentration was 16.03% at black garlic extract concentration of $14.84^{\circ}brix$ and contents of 9.26%. Reducing sugar content had maximum of value 7.30 g/mL at $24.58^{\circ}brix$ and contents of 8.08%. Total phenolic compounds contents and ABTS radical scavenging activity had maximum values at black garlic extract concentration of 20.33 and $25.02^{\circ}brix$. The results indicate that addition of black garlic extract contributed to increased reducing sugar, phenolic compounds contents and antioxidant activity of the soy sauce, but the salt concentration was not significantly affected. Conclusion: Based on the results of RSM, the optimum ranges of addition conditions for lowering the salt concentration and, increasing the sensory and functional ability of soy sauce were as follows: black garlic extract concentration of $15-25^{\circ}brix$ and content of 7.8-9.3%.

세포의 이동은 많은 생리적 반응뿐만 아니라 암 세포 침윤과 전이에 중요한 역할을 수행한다. 본 연구에서는 마늘이 암세포의 이동에 미치는 영향을 확인하기 위해, 표준 마늘과 흑마늘을 준비하고 이들을 각각 물을 이용하여 추출하거나 건조하여 추출한 추출물 4 종류를 이용하여 항침윤성과 항전이성에 대해 조사하였다. 실험결과, 암세포의 이동은 건조 후 헥산으로 추출한 분획에 암세포의 이동 억제 활성이 관찰되었다. 이 분획을 박막 크로마토그래피를 이용하여 분리정제하였으며, 이를 inhibitor of cancer metastasis from garlic #27 (ICMG-27)이라 명명하였다. ICMG-27 (6 ${\mu}g/ml$)을 세포에 처리하였을 때, IGF-1에 의한 OVCAR-3와 NIH-3T3 세포의 이동을 억제함을 확인하였다. 그러나 ICMG-27은 mouse embryonic fibroblast (MEF) 세포에서 IGF-1에 의한 이동에는 영향을 주지 않았다. 이러한 ICMG-27은 OVCA-3, SKOV-3와 MDA-MB-231 세포와 같은 암세포에서 모두 IGF-1에 의한 이동을 억제함을 관찰하였다. 마지막으로 세포이동을 일으키는 인자에 따른 ICMG-27의 영향을 확인한 것으로, IGF-1, lysophosphatidic acid (LPA), sphingosine-1-phosphate (S1P), leukotriene B4 (LTB4) 그리고, angiotensinII (AngII)에 의한 OVCAR-3 세포의 이동을 모두 억제하였다. 이러한 결과를 바탕으로, ICMG-27은 암세포의 이동을 유도하는 많은 인자들에 의한 필수적인 단계를 차단함으로써, 암세포의 이동을 억제하는 것을 확인 할 수 있었으며, ICMG-27에 의한 암세포의 항 침윤 메커니즘의 규명은 암환자의 치료에 기초적인 발판을 제공할 것입니다.

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.

The principal objective of this study was to develop a processed food using aged garlic. Pound cake samples were prepared with semi-solid aged garlic at levels of 0, 5, 10 and 15% ($25^{\circ}C$, 7 days). The pH of the batter prepared with the aged garlic ranged between 6.79 and 7.01 and the control pH was 7.21. The specific loaf volume of the pound cake prepared with the addition of 5~15% aged garlic decreased, from 2.78 to 2.51 cm3/g. The baking loss rate of the pound cake prepared with 0~15% added aged garlic also decreased by 6.91~6.42%. The lightness, redness, and yellowness values of the pound cake decreased with increases in the percentage of aged garlic. The adhesiveness, gumminess, and chewiness of the samples did not differ significantly with differing amounts of added aged garlic. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, however, was improved significantly via the addition of aged garlic. In the sensory evaluations, the pound cake prepared with 10% added aged garlic received higher acceptance scores for the properties of smell, taste, softness, moistness, adhesiveness and overall acceptability. Consequently, the optimal quality achieved in this set of experiments was with a pound cake to which 10% aged garlic had been added.

In this study, we aimed to develop functional vinegar with different levels of black garlic through two stages of fermentation. Black garlic vinegars were prepared from black garlic and water (w/w) mixed with 1:2 (BG3), 1:5 (BG6), 1:9 (BG9) and 1:11 (BG12), and adding the sugar by adjusting the soluble solids content to $14^{\circ}Brix$. The alcohol content of black garlic vinegar was 5.2-5.5% after 7 days of alcohol fermentation at $25^{\circ}C$. Acetic acid fermented was at $30^{\circ}C$ for 25 days and samples were taken at 3, 6, 9, 12, 15, 20 and 25 days. The pH of black garlic vinegar was not significantly different among the samples, but acidity was increased during fermentation. Total polyphenol contents showed irregular changes with the fermentation periods and were higher by black garlic content. At 25 days fermentation, total polyphenol contents were 18.96-56.56 mg/100 mL. Acetic acid content of black garlic vinegars was higher than other organic acids. S-allyl cysteine (SAC) contents of BG3 and BG6 were 13.03-14.54 and 1.69-2.20 mg/L, respectively. However SAC was not detected in BG9 and BG12. In 25 days fermented black garlic vinegar, the major mineral was K with a content ratio of 61-68% of total minerals. The DPPH and ABTS radical scavenging activity of 25 days fermented black garlic vinegar were stronger at higher black garlic content.

To enhance the physiological activities and reduce the off-flavor of garlic in kimchi, we manufactured kimchi seasoning replaced with 25~75% black garlic, we evaluated microbiological, physico-chemical and sensory evaluation. The changes of total aerobic and lactic acid bacteria were similar between the control and the kimchi seasoning replaced with black garlic during storage periods. The lightness of the kimchi seasoning replaced with black garlic was lower than that of the control and decrease of lightness was proportional to the concentration of black garlic. The redness and yellowness of the kimchi seasoning replaced with black garlic were decreased to the concentration of added black garlic and changes of the redness in all the samples were slightly increased during storage periods. But the yellowness did not change during storage periods. The changes of pH and acidity did not differ between the control and the samples of replaced with black garlic during storage periods. The sensory parameters including taste and flavor did not differ among treatments during storage periods. But color and overall acceptance of the control and sample replaced with 25% black garlic were higher than those of the samples replaced with 50 and 75% black garlic.

When garlic is aged for a certain period of time while maintaining proper humidity, it causes a browning reaction by its own ingredients and enzymes. In this study, the physicochemical properties were analyzed by varying the temperature conditions for aging garlic. It was found that about 20% of the weight of garlic was reduced through the aging process. During the aging process, both samples showed the highest water content on the 10th day of aging, and the water content of the two samples was similar after the aging was completed. In the analysis of total sugar content change, AG1 (22.0±0.7 vs 21.4±0.6) showed a significantly higher sugar content on the 10th day of aging, but showed a tendency to gradually decrease thereafter, whereas AG2 showed a steady increase in sugar content during the aging process (18.7 < 21.4 < 21.7 < 22.3 < 23.7). The pH change that occurred during the aging process showed the most pH change on the 10th day. In AG1, the pH gradually decreased as the aging period increased, whereas in AG2, the pH increased significantly after the 10th day. In the analysis of browning, AG1 increased sharply on the 10th day and maintained the state, and AG2 showed a significant increase in browning according to the aging process. In conclusion, based on the results of this study, if various ripening temperature conditions are set, it is judged that it will play a positive role in improving the productivity of black garlic.

붕장어와 식물류 혼합물(흑마늘, 흑삼, 흑대추)을 함께 추출함으로써 붕장어 특유의 비린내가 제거되어 맛과 향이 개선되고 피로회복 및 체력강화 기능성이 강화된 붕장어 복합조성물을 제조하였으며 그 활성을 검증하고자 흰쥐를 트레이드밀 운동 부하와 함께 5brix의 붕장어추출물(EE), 붕장어와 식물류 복합조성물 0.35 ml/100g/rat b.w. (EIM-1) 및 0.7 ml/100g/rat b.w. (EIM-2)를 투여하여 체내 지질 성분 및 항산화 효소 활성을 분석하였다. 식이효율은 정상군에 비해 EE군이 다소 낮았으나 대조군과 EIM-1 및 EIM-2군과는 유의차가 없었다. 간장의 지질함량은 정상군보다 실험군이 유의적으로 낮았고 EIM-1군이 가장 낮았다. 혈청 지질함량은 함량은 EMI-2군이 가장 낮았고 실험군은 정상군과 유의차가 없었다. 혈청 총콜레스테롤 함량은 정상군보다 실험군이 유의적으로 낮았는데 복합조성물을 투여한 EIM-2군이 가장 낮았다. HDL-콜레스테롤 함량은 트레이드밀 운동과 붕장어 및 붕장어 복합조성물을 투여함으로써 유의적으로 증가하여 정상군에 비해 EIM-1은 2.0배 및 EIM-2는 2.3배가 증가하였다. 간 글리코겐 함량은 운동을 실시한 실험군이 정상군에 비해 유의적으로 낮았으며 대조군에 비해 복합조성물을 투여한 군이 유의적으로 높았다. 간장 및 혈청의 TBARS 함량은 정상군에 비해 대조군에서 유의적으로 증가하였으나 EE군 및 EIM-1~2군은 대조군보다 낮았다. GOT 및 GPT 활성도 복합조성물을 급이함으로써 운동대조군에 비해 유의적으로 감소되었다. 붕장어 및 붕장어 복합조성물 투여에 따른 간조직에서 catalase 활성은 실험군간에 유의차가 없었으며 SOD 및 GSH-px 활성은 복합조성물 투여에 따라 대조군에 비해 유의적으로 증가하였다. 운동스트레스를 부과한 흰쥐에 붕장어와 복합조성물의 투여는 체내 콜레스테롤 함량 및 지질함량을 낮추고 항산화효소 활성을 증가시킴으로서 산화적 스트레스에 대한 생체 보호가 가능할 것으로 판단된다.
