This study investigated the effect of Lactiplantibacillus plantarum JSA22-fermented rice drinks on dextran sodium sulfate (DSS)-induced colitis in mice. Twenty-four mice were randomly assigned; No colitis (Con), colitis with tap water (DSS-only), colitis with unfermented rice (DSS-UFR), and colitis with fermented rice (DSS-FR). After inducing colitis with 2% DSS for 5 days, they were given Tap water, UFR drink, or FR drink for an additional 6 days. The DSS-FR group had significantly lower Disease Activity Index (DAI) scores compared to the DSS-only group, but no significant difference with the DSS-UFR group. Colon length was reduced in the DSS-only group. The DSS-only group had significantly higher IL-6 mRNA levels compared to the Con group, while the DSS-FR groups showed significantly lower IL-6 mRNA levels compared to the DSS-only group. These results suggest that rice drinks fermented with Lactiplantibacillus Plantarum JSA22 ameliorate the severity of DSS-colitis, by potentially reducing proinflammatory cytokines.

본 연구는 광주 내 대형마트와 온라인 마켓에서 영유아 를 대상으로 판매하는 과자류 80건 및 음료류 40건의 식 품첨가물(타르색소, 인공감미료), 곰팡이독소 및 영양성분 (자당, 무기질)을 분석하였다. 유아용 표시 식품의 기준 및 규격이 불검출로 설정된 타르색소와 사카린나트륨은 모든 시료에서 검출되지 않았다. 과자류(기타가공품) 1건에서 인공감미료인 아세설팜 칼륨이 0.07 g/kg 검출되었으나 이 는 식품첨가물의 기준 및 규격에서 정한 허용 기준치 이 하였다. 곰팡이독소는 아플라톡신 및 오크라톡신 A는 검 출되지 않았으며, 푸모니신 B1, B2 및 제랄레논이 각각 과자류에서 14건(9.78-78.94 μg/kg), 6건(5.58-11.73 μg/kg) 및 9건(2.96-8.83 μg/kg) 검출되었다. 푸모니신에 대한 기 준·규격은 따로 설정되어 있지 않았으나 타 연구 결과와 비교했을 때 비슷한 수준이었으며, 제랄레논은 식품 일반 에 대한 공통 기준·규격 이내로 확인되었다. 자당은 과자 류에서 65건(0.02-40.94 g/내용량(g)), 음료류에서 24건(0.12- 27.60 g/내용량(g)) 검출되었으나 식품유형간 유의적인 차 이는 없었으며, 타 연구 결과와 비교했을 때 그 함량도 적 은 편이었다. 다만, 검출 시료 89건 중 1건을 제외하고는 모두 1일 영양성분 기준치를 성인 기준으로 표시하고 있 었기 때문에 제품 구입 시 영유아 기준으로 오인될 우려 가 있다. 무기질은 대부분의 시료에서 검출되었으며 과자 류 중 4건의 시료에서 내용량 당 아연 함량이 상한섭취량 (1-2세: 6 mg/일, 3-5세: 9 mg/일)을 초과하는 수준이었다. 아연 강화식품이나 보충제의 과다 섭취가 인체의 유해성 을 보인다는 다수의 보고가 있으므로 섭취시 유의할 필요 가 있다. 나트륨은 과자류 80건 중 16건이 영유아용 표시 식품의 기준을 초과하였으나 모두 품목제조보고서상 영유 아 섭취 대상 식품으로 표시하지 않아 해당 기준을 적용 할 수 없었다. 따라서 영유아용 표시 식품의 기준·규격을 설정과 함께 현재 시행되는 기준·규격이 알맞게 적용될 수 있도록 표시 기준 강화 등의 제도적 개선이 필요할 것으 로 보인다.

In conclusion, the result of this study determine the preferences and the affecting factors for the traditional Korean drinks in children of Korea, Vietnam, and China.

The purpose of this study was to investigate the intake status of energy drinks, knowledge of caffeine and the perception on intake of energy drinks by university students. We surveyed 351 university students from October 25, 2017 to January 25, 2018. The subjects (70.9%) consumed energy drinks more than once. Male students consumed energy drinks more frequently than the female ones. A huge portion (68.3%) of the subjects consumed energy drinks to recover from fatigue and reduce sleepiness. Moreover, they consumed most of the energy drinks at home and the university library. The main anticipated efficacy of energy drinks was the relieving drowsiness. Respondents (86.3%) perceived that energy drinks could be hazardous to the health of human beings. The main risks of consuming energy drinks were sleep disorders, addiction problems and heart beating. The main recognized effects of energy drinks were relieved drowsiness and decreased fatigue. The major side effects were heart beating, nausea, vomiting, heartburn and sleeping disorders. This study suggests that nutritional education is needed to confirm the recommendation of daily intake for caffeine and to raise awareness about the side effects of energy drinks.

This study examined the intake status of energy drinks and related factors among university students in Yeungnam region, Korea. A total of 456 students participated in the study by a self-administered questionnaire. About 26% of the respondents never took energy drinks, whereas about 30% took them previously, but do not take them now. Almost 45% answered that they have taken them up to now. The reasons for first intake of energy drinks were ‘necessity for myself’ followed by ‘curiosity’, ‘recommendation of friends’, and ‘seeing advertisement’, and Chi-square test showed that there was a significant difference according to dwelling status. About half of the respondents took them since high school, and the main reason for energy drink intake was ‘to stay awake’. About 45% of the respondents indicated that they increased study hours after taking energy drinks, whereas almost 40% answered that they had little effect on them. Over half of the respondents experienced side effects after energy drink intake. About one-fifth of the respondents mixed the energy drinks with alcoholic beverages to make them taste better. In addition, in the result for the multinomial logistic regression analysis, gender, grade, dwelling status, smoking status, alcohol drinking status, perception of effect of energy drinks on health, and perception of benefit level of caffeine were the predictors for the respondents who never took energy drinks in comparison with the respondents who have taken them up to now. On the other hand, for the respondents who took them previously but do not take them now compared with those of having taken them up to now, the predictors were dwelling status and smoking status. These results imply that dietary education from childhood regarding knowledge and side effects of energy drinks should be offered.

The purpose of this study was to investigate the intake of energy drinks and awareness of caffeine among middle school students. The subject was 313 middle school in Incheon area. The questionnaire respondents are consisted of 133 male students and 180 female students. The recognition result that allowed multiple responses to energy drink types was recognized by hot six at 28.9%, followed by red bull 24.3%, monster energy 13.8%, wolf energy 8.0% and taurine soda 6.9%, respectively. There was a significant difference in the experience of energy drink intake, intake reason, intake time and place (p<0.05), but there was no significant difference in intake frequency and place (p>0.05). There were significant differences in experience and frequency of energy drink intake (p<0.05), but there was no significant difference in intake reason, choice criteria, intake time and place (p>0.05). The result of the perception of energy drinks according to gender was 2.25 points for male students and 2.61 points for female students in the question 'caffeine is also present in tea, green tea, cola and chocolate'. There was a significant difference between male and female students (p<0.05). As a result of the recogniton of energy drinks, "the appropriate amount of caffeine is cleared and the concentration improves." When asked, "low body weight is 2.24 points, normal 2.27 points, overweight 1.89 points, obesity 2.46 points (p<0.05). There was a statistically significant difference in body mass index (BMI) between the two groups (1.95 for low body weight, 2.10 for normal body weight, 1.62 for overweight and 2.43 for obesity). Regression analysis showed that R2=0.007 and F=2.798, respectively. Significant differences were found at the significance level of p<0.05. Energy drink consumption expenditure(β= 0.121, p<0.05), sleep time(β=0.130, p<0.05), and caffeine perception(β=－0.162, p<0.05) were significant determinants of energy drinks intake.

에너지 음료는 카페인을 주성분으로 타우린, 비타민 같은 다른 energy-enhancing 성분을 함유하고 있다. 미국과 유럽에서는 글루쿠로노락톤이 에너지 음료에 첨가될수 있으나, 국내에서 의약품으로는 허가되어 있다. 따라서 식품 첨가물로는 그 사용이 금지 되어 있어, 지속적으로 수입 및 유통 음료에서 시험검사를 하여 규제하고 있다. 현재 분석법으로 사용하는 LC-PDA 법은 복잡한 유도체화 과 정을 거치고, 음료 중에 당류들이 위양성 결과를 나타내 기도 한다. 이런 기존 방법의 단점을 개선하기 위해 HILICESI- MS/MS (hydrophilic interaction liquid chromatography coupled to electrospray ionization tandem mass spectrometry) 를 이용한 분석법을 개발하고, 선택성, 직선성, 검출한계, 정량한계, 정밀도, 정확성, 재현성에 대하여 분석법 유효성 검증을 수행했고, AOAC, EURACHEM 가이드라인에 부합되는 결과를 얻었다.

목 적: 고카페인 에너지음료가 시기능에 미치는 영향을 알아보고자 하였다. 방 법: 고카페인 에너지음료의 주요 소비층인 대학생 30명을 대상으로 굴절이상도, 동공크기, 눈물막 파괴 시간, 순목횟수, 폭주근점, 조절력, 근거리 조절 용이성, 근거리 융합성 이향 용이성을 측정하고 분석하였다. 결 과: 고카페인 에너지음료 섭취 후 굴절이상도, 순목횟수, 폭주근점은 거의 변화가 없었으며 동공크기 는 약간 커지는 경향을 보였고, 조절력은 섭취 60분 후에는 최대 증가를 나타냈고 섭취 90분 후에는 복귀되 는 시점으로 나타났다. 눈물막 파괴시간, 폭주근점, 근거리 조절 용이성, 근거리 융합성 이향 용이성은 섭취 전과 비슷한 양상으로 나타났다. 결 론: 고카페인 에너지음료의 섭취가 시기능에 영향을 미칠 수 있으므로, 지나친 섭취는 지양해야 할 것이다.

This study was conducted to determine the content of inorganic metals in soft drinks distributed locally in markets. 6 trace metals (Fe, Ca, Zn, Na, Mg, and K) were detected in 16 kinds of drinks, 80 samples. The average concentration of inorganic metals in vegetable drinks was relatively higher than that of mixed drinks or carbonated drinks. The concentration of calcium, which is advisable inorganic metals for the growth of skeleton and the prevention of osteoporosis, hypertension, was very high and needed to be careful for the consumer who is suffer with lithiasis. Although carbonated drinks are very popular with the children and adolescence owing to the unbalance of the intake of Ca and P, habitual drinking could cause obstruction in skeletal growth and metabolism of Fe, Cu, and Zn. So, it is suggested that more practical study is needed for the intake of inorganic metals.

Analytical method for synephrine and octopamine in citrus fruits, drinks containing citrus fruit, and human urine was developed using gas chromatography / mass spectrometry(GC/MS). Silylation with MSTFA, acetylation with MBTFA, and trimethylailylation with MSTFA followed by tritluoroacetylation with MBTFA were compared. The selective derivatization of aynephrine and octopamine was optimized with two derivatizing reagents ; MSTFA and MBTFA. The ion at mlz 267 was monitored to characterize the benzyl group of the both compounds. Synephrine was detected in the concentrations of 0.46-1.88 ug/g for citrus fruits and 1.2-8.1 ug/ml for drinks. The urinary excretion data of aynephrine showed the highest concentration at the period of 8-20 hours after drinking orange juices and total amounts of its urinary excretion calculated as a parent compound was 11-14% of a dose during 48 hours. Octopamine was not detected in citrus fruits, drinks, and human urine.

Purpose – This paper explores the contribution lean makes to service levels by addressing lean thinking application in logistics process improvement within a MNC soft drinks manufacturer situated in the United Arab Emirates, and identifies the most significant sources of wastes and their interdependence and highlights key attributes of successful lean implementation. Research design, data, and methodology - This case study examines key logistics employees’ perceptions on lean methodology. Results - The results highlight the most significant types of wastes in logistical processes and illustrates ways to eliminate wastes and streamline process flow. The importance of the human role within lean methodology is also identified. Findings suggest that managers should follow both a micro and macro approach when implementing lean practices, as focusing on one waste often leads to ignoring the significance of other wastes. Conclusions - This study highlights the importance of implementing lean at both micro and macro levels and shows how staff involvement increases the efficacy of lean thinking. It offers guidance towards the efficiency of creating value stream mapping processes in situ, which considers different wastes and their interdependence. Managers with limited resources are encouraged to implement lean methodology taking cognizance of these factors.

The aim of this study was to evaluate the efficacy of red ginseng drinks as school meal drinks for 456 middle and high school students in Cheongdo-gun, North Gyeongsang Province. In preliminary studies, we focused on saponin with an efficacy of Rg 1 and Rg 2 in prepared red ginseng drinks. The health benefits and sensory characteristics were also investigated. For the frequency analysis, the satisfaction of the drinks as beverages serving as a school meal was relatively low, and the demand for fruit drinks was high. The result of sensory evaluations indicated a positive response of > 50.0% for the container packaging and design, daily intake, and tastes. Regarding the correlation analysis on red ginseng drinks, there were significant differences (p < 0.01) in the response to packaging (a daily intake) and design. In addition, health and learning benefits showed a very high correlation at the p < 0.01 significance level.

The effect of irradiation of heat treatment either alone or in combination on the shelf-life of mixed mountain edible herb drinks (MMEHD) was investigated during storage. The MMEHD made from fresh Spuriopinella bracycarpar, Ligularia fischeri and Aster scaber was gamma -irradiated at doses of 0.1 kGy to 1 kGy. Microbial population, color change, vitamin C content, and sensory quality were evaluated during storage at 4, 25 and 35oC. Heated MMEHD induced the growth of total counts, mold and yeast as compared to the non-heated MMEHD. While some reduction in the microbial growth was observed in 1kGy-irradiated groups of both with or without heating. In both groups, L and b values decreased, but a value increased during storage. Also, heating drinks showed increased L and b values and reduced a value, compared to the non-heating drinks. Non-heated drinks showed 82% loss of vitamin C, whereas 25% loss of vitamin C was occurred in the irradiated drinks during storage at 4oC for 4days. In the meanwhile, non-irradiated heating drinks showed 99% loss of vitamin C, but irradiated heating drinks showed 58-65% reduction of vitamin C. Non-irradiated drinks without heating showed more bright color than irradiated ones, but irradiated drinks showed more enhanced brightness during storage. Also, irradiated drinks showed better falvor, sensory quality, and overall acceptability than non-irradiated drinks.
