This study was performed to investigate anti-oxidant of red pepper and Zanthoxylum schinifolium ethanol extract, main ingredient of mara source. Anti-obesity effects of red pepper and Zanthoxylum schinifolium ethanol extract were investigated with mice fed high fat diet for 8 weeks. Sixty mice were classified to 6 groups of ND (normal diet), HFD (high fat diet), RP (high fat diet+red pepper (0.1 g/60 kg)), CP (high fat diet+Chinese pepper (0.1 g/60 kg)), RCP (high fat diet+red pepper : Chinese pepper=1:1 (0.1 g/60 kg)), HCA (high fat diet+HCA (0.1 g/60 kg)) experiments. This research showed that final weight, weight gain, food efficiency ratio, and river weight were decreased by the addition of red pepper and Zanthoxylum schinifolium ethanol extract comparing to those of HFD group. The plasma triglyceride and LDL cholesterol concentration of red pepper ethanol extract and Zanthoxylum schinifolium ethanol extract group was lower than that of high fat diet group. HDL-cholesterol concentration of red pepper ethanol extract and Zanthoxylum schinifolium ethanol extract group was higher than those of high fat diet group. These results suggested that red pepper and Zanthoxylum schinifolium ethanol extract might be useful for obesity control and good source of functional materials.

수경재배 인삼으로 제조한 식초가 고지방 식이를 섭취한 마우스의 체중 및 지질대사에 미치는 영향

오영주(Young-Joo Oh),권승혁(Seung-Hyuk Kwon),최금부(Kum Boo Choi),김태석(Tae-Seok Kim),여익현(Ik-Hyun Yeo) 한국식품과학회 2014 한국식품과학회지 Vol.46 No.6

본 연구에서는 수경재배 인삼의 전초를 이용하여 식초를 제조하여 진세노사이드의 패턴 및 함량 변화를 확인하고자 하였으며, 고지방 식이로 유도된 비만 쥐에 수경재배 인삼 식초를 투여하여 체중, 체지방 및 지질대사를 분석함으로써 항비만 식품으로서 가능성을 확인하고자 하였다. 실험 결과 수경재배 인삼으로 식초제조 시 산도는 5.60±0.24%이었으며, 초산 발효 과정에서 진세노사이드 Re가 감소하고 진세노사이드 Rg2가 약 4배 수준 증가하는 것으로 확인되었다. 수경재배 인삼 식초의 항비만 효과를 확인하기 위해 4주령 C57BL/6J mice에 고지방 식이를 투여하면서 수경재배 인삼 식초 및 녹차추출물을 8주간 투여하였다. 실험식이 종료 후 체중 변화를 비교한 결과 수경재배 인삼초투여군(HGV) 및 녹차추출물투여군(GT)은 고지방식이군(HFD)과 비교하여 유의적인 체중감소효과가 관찰되었다. 체성분 분석결과 복부지방 및 피하지방의 함량이 낮은 것을 확인할 수 있었으며, 개복 후 복부 주위의 지방을 적출하여 무게 측정 시 고지방식이군(HFD)과 비교하여 수경재배 인삼초투여군(HGT) 및 녹차추출물 투여군(GT)은 각각 85.5, 83.3% 낮아진 것으로 확인되었다. 혈중 지질프로파일 분석 결과 수경재배 인삼초투여군(HGV) 및 녹차추출물투여군(GT)은 중성지방, 총콜레스테롤, LDL 콜레스테롤이 고지방식이군(HFD)과 비교하여 유의적으로 낮아졌으며, HDL 콜레스테롤이 증가된 것으로 확인되었다. 고지방 식이에 의한 간 독성을 관찰하기 위해 AST 및 ALT 효소 활성을 측정하였으며, 수경재배 인삼초투여군(HGV)은 고지방식이군(HFD)과 비교하여 각각 67.3, 75.1%, 녹차추출물투여군(GT)은 각각 68.4, 75.1% 감소 효과가 관찰되었다. 이와 같은 결과를 통해 수경재배 인삼으로 식초 제조 시 흡수율이 우수한 proginseonside Rg2의 함량이 증가되어 생리활성 강화 효과를 기대할 수 있으며, 체지방 축적을 억제하고 혈청 지질 조성을 개선시킴으로써 항비만 식품소재로 가치가 있을 것으로 생각된다. The aim of this study was to develop hydroponic-cultured ginseng vinegar (HGV) containing ginsenoside Rg2 in order to its anti-obesity and anti-hyperlipidemic effects in C57BL/6J mice. HGV was prepared by two-stage fermentation. The ginsenoside Rg2 contained in acetic acid-fermented HGV increased by 4.0 times compared to that in pre-fermented HGV. To measure the anti-obesity effect of HGV, thirty two mice were randomly divided into four groups: normal diet group (ND), high-fat diet group (HFD), high-fat diet-supplemented with HGV group (HGV), and high-fat dietsupplemented with green tea extract group (GT). Body weight, fat weight, and liver weight decreased in the HGV group. The HGV group also showed lower plasma levels of low-density lipoprotein (LDL)-cholesterol and triglycerides, and higher levels of high-density lipoprotein (HDL)-cholesterol compared to the corresponding levels in the HFD group. Furthermore, there were significant decreases in plasma aspartase aminotransferase (AST) and alanine aminotransferase (ALT) levels in the HGV group compared to the corresponding levels in the HFD group. These results suggest that HGV can be used as an anti-obesity therapeutic agent or functional ingredient.

High intakes of sodium may increase the risk of hypertension or cardiovascular diseases. According to the 2010 Korea National Health and Nutrition Survey, the average intake of sodium was 4,878 mg/day with salt, kimchi, soy sauce, fermented soybean paste and Ramyeon being the five main sources of sodium. In order to identify solutions to reduce the intake of sodium, we investigated the intake patterns and eating behaviors of Ramyeon among 347 college students (male 146, female 201) using survey questionnaires. The average age of study subjects was 23.7 years for males and 20.5 years for females. The average Body Mass Index (kg/m2) was 21.9 for males and 20.1 for females. The average frequency of Ramyeon intake was 2.0 times/week. The main reason for eating Ramyeon was convenience (56%), followed by good taste (27%), low price (11%) and other reasons (9%). The criteria for choosing Ramyeon were taste (72%), convenience (14%), price (7%), nutrition (1%), and the other factors (2%). Males` average intake of Ramyeon soup (61%) was higher than that of the females (36%). The estimated intake of Ramyeon soup by survey showed a positive correlation with the measured intake of Ramyeon soup. Sodium contents of Ramyeon were measured separately for the noodles and the soup, which were 1,185 mg/serving and 1,148 mg/serving each. Therefore, the amount of sodium intake can be reduced if students eat less Ramyeon soup. Also, we observed that dietary behaviors and soup intakes of Ramyeon between the sexes were different. Appropriate nutritional education for proper eating habits may help decrease the intake of sodium. (Korean J Community Nutr 18(4) : 365~371, 2013)

Ethylene is Known to have properties such as retardation of longitudinal growth and leaf expansion, increase in stem thickness, and stimulation of overall growth. This experiment was conducted to provide the background for application of beneficial properties of ethylene to bean sprouts production. Samples were put on the treatment for 4 days total and alt the parameter were measured at 5th day of the experiment. The results are as follows : Mean body length from upper part was decreased 2.2cm, but middle part and lower part were rather increased 1.5cm and 0.2cm, respectively, compared with the mean values of controls. Mean difference in stem thickness for upper, middle, and lower part of the stem were 0.5mm, 0.4mm, and 0.2mm respectively. Especially, it is a great way to change shape of the bean sprout in desired way without using any chemicals, such as pesticides or growth stimulation reagent.

The results clearly stated that the growth and duality of bean sprouts were influenced in great extents by water spraying method employed. When fresh water was used, water supply through the bottom caused rapid increase in internal temperature ( $gt; 26℃ after 48 hours) and carbon dioxide (CO₂ level (9-10% before water spraying, measured on 15-35cm from bottom of the vessels), which resulted in obstruction of respiration and accumulation of organic compounds in stem of the sprouts. These became main reason of the unpleasant order and freshness problem of the sprouts upon completion of the growth. On the other hand, when water supply from the top (through the multiple holed container at the top of the vessel) was employed. the growth and yield of the sprouts were much unproved due to the lowering of internal temperature ( $lt; 23℃ after 48 hours) and increase in release of CO₂ gas (7-8% before water spaying). The results of the experiments showed that water spray method is one of the key factors for the growth of the bean sprouts. It was concluded thai the employment of the method which filling up vessel with water at one time through the multiple holed water container attached on the top, instead of existing going and returning shower method, possibly avoid the decomposition, overgrowth and browning of the bean sprouts 6y decrease in internal temperature and improvement of CO₂ release.
