The quality characteristics of rice wine seed mash and rice wine made with different lactic acid concentrations were investigated. The pH decreased along with the lactic acid concentration. The total titratable acid content of the rice wine seed mash was lowest when 0.5% lactic acid was added, and the ethanol contents of the mash samples were not significant. The results of the measurement of the microorganism number, C (cell numbers of the total bacteria and the lactic acid bacteria), decreased along with the lactic acid concentrations of the mash samples. The yeast cell numbers of the rice wine seed mash samples according to the lactic acid concentrations were high (0.5, 0.3, 1.0, control, and 0.7%, respectively). The pH and total titratable acid levels of rice wine according to the lactic acid concentration were stable during fermentation, according to the increase in the amount of lactic acid. The organic acids in the rice wines were highest in the lactic acid. The rice wines to which lactic acid had been added had lower acetic acid contents than the control. Also, the acetic acid contents decreased along with the lactic acid concentrations, except in the rice wine treated with 1.0% lactic acid. The ethanol contents of the tested rice wines were not significant. All in all, in the sensory evaluation, the rice wines treated with 0.5 and 0.7% lactic acid scored higher than the other treatments.

Generation of biogenic amines (BAs) and physiological activities of Makgeolli, Korean rice wine, were investigated during fermentation under different temperatures (20, 25, and $30^{\circ}C$) and time (3, 5, and 7 days). The pH was 3.96~4.36 during fermentation and the acidity increased proportionally with temperature and time. Alcohol and total phenolic contents peaked on day 5 at 25 by 9.0~9.8% and $3.01{\pm}0.07mg/g$, respectively. The organic acid mostly produced was lactic acid, which increased gradually with temperature and time. Formation of biogenic amines comprised of tryptamine and putrescine was observed during fermentation: 6.91, 11.70, and 15.63 mg/mL of tyramine on day 7 at 20, 25, and $30^{\circ}C$, respectively. Antioxidant activities from DPPH and FRAP assay were high in the order of $25^{\circ}C$>$20^{\circ}C$>$30^{\circ}C$ while that from ABTS assay was high regardless of temperature. Processed at 1 mg/mL and $30^{\circ}C$, the inhibitory effect on ${\alpha}$-amylase was $67.99{\pm}0.11$, $73.64{\pm}0.43$, and $75.51{\pm}0.26%$ on days 3, 5, and 7, respectively, which increased proportionally with temperature and time. Inhibitory activity on lipid accumulation in 3T3-L1 adipocytes was the highest in Makgeolli fermented on day 5 at $25^{\circ}C$. This study shows that fermentation at $25^{\circ}C$ for 5 days yields Makgeolli of the best quality with high bioactivities but no biogenic amines.

The purpose of this study was to investigate the perceptions and preferences held by the general public concerning jeungpyun. Self-administered questionnaires were collected from 484 residents in Daegu and Gyeongbuk. The questionnaires contained questions on the recognition of jeungpyun, purchasing, frequency, purchasing factor, and preferences for and purchasing of jeungpyun containing different kinds of makgeoilli. According to the survey, females were higher than males (31.4%) by 69.7%, and that for ages 20~30' was the highest. Most of them were students (39.7%), and 81.7% of them had an income of under 4,000,000 won per month. The results of the eating frequency rate showed that over half of the people had jeungpyun once a month, and the recognition of jeungpyun for females (3.63) was higher than that for males (3.09). The respondents who joyed eating jeungpyun mentioned 'good taste and texture' as the top reason for eating jeungpyun, and 'different food and bad flavor' was mentioned as the reason for disliking it. As a result, popularization of jeungpyun was based on two factors: 1) fundamental factor and 2) external factor, and both significantly influence the preference for and purchasing of jeungpyun,-. Therefore, future studies should be conducted to improve preference for jeungpyun as a functional food. The results of preference and purchasing show that jeungpyun prepared with rice, rubus coreanum miquel, black bean, grape and green mume makgeoilli.

A general screening test for the expression of antioxidative activity was performed on over 36 cultures belong to yeast isolated from soy sauce, Makkuli, and molasses. Antioxidative activities of yeasts were examined by measuring oxidation such as peroxide value and thiobarbituric acid value in fish oil. Of these cultures, Saccharomyces cerevisiae IFO 2114 were found to have strong antioxidative activity. Saccharomyces rouxii and Torulopsis etchellsii isolated from soy sauce showed the strongest antioxidative activity among yeasts. Pichia ohmerii isolated from Makkuli showed the strongest antioxidative activity and Candida versatilis isolated from molasses showed also relative strong antioxidative activity.

자판기를 단기적인 홍보 마케팅에 활용하는 사례들이 늘고 있다. 과거에는 사람이 자판기 안에 들어가 상품을 내주는 '인간자판기' 식의 활용이 붐을 이루었었다. 주로 미인이 자판기 안에 들어가 브랜드가 감성적으로 어필하는 효과를 안겨 주었다. 그러나 이런 홍보 마케팅은 여러 곳에서 되풀이함으로 인해 참신성이 떨어져 최근에는 시큰둥해졌다. '보다 기발하고 자극적인 방법이 무엇일까?' 다음으로 등장하게 된 게 자판기의 의외성을 부각시키는 컨셉이다. 고객이 예상했던 뻔한 내용상품이 아니라 놀랄만한 상품과 서비스, 재미를 제공한다. 일례로 코카콜라의 홍보 마케팅에서는 꽃다발을 내주기도 하고, 막걸리 업체 배다리의 전시회 홍보 마케팅에서는 투출구에서 사람 손이 나와 막걸리를 따라주기도 하고 선물도 건넨다. 최근 매일유업에서 '우유속에'라는 유제품 출시를 기념하여 펼쳐진 '해피 프레젠트 (Happy Present) 캠페인'도 이 범주에 속한다. 말 그대로 자판기가 다양한 선물을 하는 컨셉이다. 기존 유사 홍보마케팅과 차별성이 있다면 고객이 미션을 수행해야 선물이 주어지는 참여형 프로그램이라는 점이다. 의외성에 대한 기대와 재미를 결합한 절묘한 홍보 마케팅이다. 저렴한 비용에 효과는 만점인 자판기 홍보 마케팅의 장점을 여실히 느끼게 한다. '우유속에' 자판기 홍보 마케팅에는 어떠한 기발함이 숨어있을까?

The presence of bacterial strains showing antagonistic activity to common pathogens found in a variety of fermented foods in Korea was explored. A bacterium inhibiting the growth of pathogens such as Aspergillus terreus (KCTC6178), A. flavus (KCTC6984), Staphylococcus aureus (KCCM12214), Escherichia coli O157:H7 (KCCM40406), Bacillus cereus (KCTC1012), Cryptococcus neoformans (ATCC208821), Salmonella typhimurium (ATCC19430), and Listeria monocytogenes (KCTC3569) was isolated from Makgeolli, a Korean traditional rice wine. The strain showing high antipathogenic activity was identified as B. amyloliquefaciens based on the nucleotide sequence of the 16S ribosomal RNA gene. Compared with B. amyloliquefaciens KCTC1660, whose genome has been sequenced, the isolate exhibited significantly low activities of starch-degrading enzymes and high resistance to high temperature and low pH.
