막걸리는 탁주이지만, 탁주가 모두 막걸리인 것은 아니다. 우리는 막걸리와 탁주를 뒤섞어서 사용한다. 탁주는 그 색깔을 보아 회주(灰酒), 백주(白酒)라고도 했고, 그 형상을 보아 재주(滓酒)라고도 했다. 막걸리는 옛 문헌에서는 막걸리 요, 또는 탁료라는 표현을 많이 썼다. 한자로 막걸리(莫乞里) 또는 탁백이(濁白伊)라고 쓰기도 했는데, 이는 차음해서 표현한 것이다.

We examined biogenic amine (BA) production as well as the diversity of bacterial flora in 11 types of commercial makgeolli stored at 4 and $20^{\circ}C$. Moreover, we studied the BA-producing activity of three L. plantarum strains isolated from makgeolli. At $20^{\circ}C$, the BA content was highly increased and the denatured DNA bands were more variable in non-sterilized makgeolli compared to sterilized makgeolli. The major BAs produced in commercial makgeolli were histamine and putrescine. Histamine, tyramine, putrescine, and cadaverine were produced in excess by inoculation of the three L. plantarum isolates to makgeolli stored at $20^{\circ}C$ for 21 days. These results suggest that some L. plantarum strains in makgeolli can produce different types of BAs, depending on the extent of degradation of makgeolli.

This study was conducted to investigate the effect of Makgeolli (MG) and Makgeolli GiGemi (MGG) on blood flow, serum lipid improvement in vivo, and inhibition of angiotensin converting enzyme (ACE) in vitro. The activities of serum AST and ALT were increased by ovariectomy. Serum AST levels were decreased to $77.71{\pm}13.97$ and $74.57{\pm}14.90\;unit/ml$ in the OVX-MG50 and OVX-MGG50 groups compared to the OVX-control group ($91.14{\pm}12.02\;unit/ml$). Serum ALT levels were decreased to $34.00{\pm}8.41$ and $30.43{\pm}3.60\;unit/ml$ in OVX-MG50 and OVX-MGG50 groups compared to the OVX-control group ($37.14{\pm}5.40\;unit/ml$). Serum total cholesterol and triglyceride contents decreased in the sham group compared with OVX-control group by ovariectomy. Six weeks feeding of MG and MGG resulted in a decrease to $116.14{\pm}36.02$ and $109.14{\pm}11.55\;mg/dl$ compared to the OVX-control group ($120.43{\pm}8.36\;mg/dl$) in serum total cholesterol, and triglyceride levels were decreased to $52.43{\pm}12.41$ and $47.29{\pm}12.08\;mg/dl$ in the OVX-MG50 and OVX-MGG50 groups compared to the OVX-control group ($58.57{\pm}5.47\;mg/dl$). The level of HDL-cholesterol in the OVX-control group was significantly reduced to $51.29{\pm}20.49\;mg/dl$ compared to the sham group ($72.29{\pm}10.29\;mg/dl$), but it was increased to $70.71{\pm}19.53$ and $62.00{\pm}20.20\;mg/dl$ with MG and MGG supplementation. Furthermore, the effect of the MG group was higher than the MGG group. Microscopic observation showed that whole blood passed smoothly through the micro channels in the MG and MGG supplemented groups. The platelet aggregation ability of the groups treated with MG and MGG was less than that of the OVX-control group. In vitro assay, the angiotensin converting enzyme (ACE) activity was significantly inhibited by MG and MGG (82.6% and 68.9% inhibition at 0.4 g/ml). These results suggest that the beneficial effects of MG and MGG may be used to improve on the lipid metabolic syndrome of menopausal women. In addition, MG and MGG might improve blood homeostasis mediated activities via antiplatelets and MG and MGG may be used as antihypertensive functional foods and nutraceuticals.

This study aimed to characterize and compare makgeolli (a Korean rice wine) made using different raw materials. Five cultivars of rice and wheat flour were used as starch materials for makgeolli and assessed for their moisture, crude lipid, crude protein, and crude dietary fiber content. Overall, wheat flour was higher in crude lipid and crude protein and lower in moisture than rice. Makgeolli characteristics were assessed for pH, total acids, organic acids, free sugars, color and appearance. We found no significant differences in pH and total acids between makgeolli made from rice and wheat flour. In addition, the major free sugar in the makgeolli made from rice and wheat flour was glucose, although the content of total free sugars was lower in the wheat flour makgeolli (67.75 mg/mL) than the rice makgeolli (76.41~84.53 mg/mL). In terms of organic acids content, the total organic acid content was highest in the wheat flour makgeolli, while the major organic acids of the makgeolli made from rice and wheat flour were lactic acid and succinic acid, respectively. There were no significant differences in color values among rice makgeolli, but the rice makgeolli was higher in sensory scores (indicating preference) than the wheat flour makgeolli. As the degree of milling increased, moisture, crude lipid, and crude protein in the rice decreased. Acetic acid in the makgeolli also decreased, while there were no significant differences in pH, total acids, free sugars, color values, and sensory scores (except fruitiness). Traditional nuruk (TN) and cultured nuruk (CN) were compared as fermentation starters. Nuruk is a Korean traditional starter for fermentation of makgeolli and a raw material for makgeolli making. The pH in the makgoelli made with TN and CN were 4.29~4.65 and 4.02~4.23, respectively. Total organic acid content was higher in the TN makgeolli (3.5~6.3 mg/mL) compared to the CN makgeolli (2.3~4.3 mg/mL). The content of free sugars in the makgeolli made with CN was higher (59.44~73.34 mg/mL) than that with TN (56.45~59.75 mg/mL). The Hunter color test showed that makgeolli made with TN was lighter and higher in red and yellow color compared to CN. Overall sensory acceptability was higher in the CN makgeolli compared to the TN makgeolli.

The purpose of this study was to offer primary information for development of Makgeolli adapted to the tastes of Chinese and marketing strategies for promoting consumption of Makgeolli in the Chinese market. This study was intended to investigate the Makgeolli drinking behavior through a survey and the sensory properties and preference of fresh and sterilized Makgeolli through sensory evaluation focusing on the Chinese students in Korea, becoming potential consumers of Makgeolli. The survey was conducted from October 9th to October 30th, 2013, and then 117 copies were adopted for the analyses. The results are as follows. 71.8% of the subjects liked Makgeolli, 56.4% drank 5-6 times a week, and 25.7% drank more than 2 bottles at a time. 61.5% of the subjects had purchasing experience. The routes of collecting information about Makgeolli were acquaintances(66.7%) and media sources(28.2%). In the sensory evaluation, sterilized Makgeolli(BS) that has a fresh odor, sweet and sour taste, cooling sensation, and good aftertaste got the best score in the overall acceptability, and fresh Makgeolli(KD) that has a strong nuruk odor, turbidity, bitter taste, and heavy mouthfeel got the lowest score in the overall acceptability. These results show that sweet, fresh, and refreshing Makgeolli suits Chinese's taste and word of mouth marketing through the expansion of tasting events would promote Makgeolli consumption in the Chinese market.

The optimum conditions for manufacturing pomegranate makgeolli, cloudy Korean rice wine, treated with different levels of pomegranate (Punica granatum L.) juice concentrate were investigated. The pH, titratable acidity, amino acid content, soluble solid content, and alcohol content were measured, and the sensory properties of the makgeolli were evaluated. The pH, titratable acidity, soluble solid content and alcohol content of pomegranate makgeolli increased as the addition level of pomegranate juice concentrate increased. The amino acid content of makgeolli significantly decreased with increasing addition level of pomegranate juice concentrate. In the sensory evaluation, makgeolli with 3% pomegranate juice concentrate added during one-step-brewing had the most preferable flavor, sweetness, bitterness and overall acceptance among all samples. In conclusion, the addition of 3% pomegranate juice concentrate during one-step-brewing for makgeolli would be the best conditions for manufacturing pomegranate makgeolli.

The objective of this study was to manufacture three kinds of domestic sweet potato Makgeolli using a mixture design and an optimization technique. The effects of four different manufacture methods, such as simultaneous saccharification and fermentation (SSF) with or without malt and separate hydrolysis and fermentation (SHF) with or without malt were determined. The SSF methods of Makgeolli produced higher alcohol content than that of SHF methods. The sensory score was not influenced by different making methods. Fourteen experimental points were selected, and rice (10~50%), sweet potato (10~50%) and water (40~60%) were chosen as independent variables. The measured responses were sensory preference, total polyphenol content, and DPPH radical scavenging activities. The ratio of the optimum sweet potato Makgeolli mixture formulation was developed as 15.11 (rice): 44.89 (sweet potato): 40 (water) using the optimization technique. The desirability of the optimum mixture formulation was 0.839. Yellow sweet potato Makgeolli using the optimum mixture formulation produced higher soluble sugar content compared to others. Regular sweet potato Makgeolli produced higher pH. The purple sweet potato Makgeolli's total polyphenol content and DPPH radical scavenging activity were measured to be the highest at $771.91{\pm}1.42mg\;GAE/{\ell}$, $131.55{\pm}4.03%$.

In this study, the quality characteristics of Jeung-pyun with different amounts of Makgeolli (50, 100, 150, and 200 mL) were investigated, and standardization of the Jeung-pyun production process is suggested. Higher Makgeolli contents resulted in an increase in Jeung-pyun qualities such as the b value, air cell size, springiness, and cohesiveness, whereas Jeung-pyun characteristics such as the L values, pH, number of air cells, hardness, and gumminess significantly decreased. The specific volume was highest following method M-150, and the expansion rate was lowest following method M-200. Altering the Makgeolli content did not significantly differ in moisture content and b values. In the sensory evaluation results, the M-150 method produced the highest-ranking results for all tested items (i.e., overall acceptability, appearance, flavor, taste, and texture). Therefore, this study suggests that Jueng-pyun produced with the M-150 mixing ratio has excellent quality and sensory characteristics. Furthermore, the results of this study can be used as preliminary data for the standardization of Jueng-pyun production.
