The purpose of this study is to find out the economic impacts of the CASSAVA project, IPM project, Post-Harvest project, and RICE project among 12 projects that are being worked on by the Asian Food & Agriculture Cooperation Initiative(AFACI) established in 2009. Reliable data such as FAO STAT etc. was utilized for the analysis on the economic impacts of each project and the data of an investigation on principal investigators of the nation who participate in each project was used for the analysis of the additional necessary information. According to the economic impacts analysis result, the economic impacts will occur and can be measured as an economic costs as follows: a total of $1,187,404 in Thailand for the next 19 years through the CASSAVA project, $2,358,299 in Indonesia for the next 18 years through the Post-Harvest project, $62,451,317 in Vietnam for the next 13 years through the Post- Harvest project and $60,629,555 in Nepal for the next 13 years through the RICE project. The AFACI project is a small project that annually supports each country that participates each project with approximately $ 10,000. Despite the small-scale project, the estimated result of economic impacts showed that great economic impacts occurred for its scale of the support. Thus, it is deemed that a search for ongoing methods that contribute to the role expansion of Korea and the agricultural development of the recipient country will be needed through the expansion and complementation of a low-cost and high efficiency Official Development Assistance(ODA) such as the AFACI project.

In this study, we compared diet related attributes such as food taste preference, food consumption frequency and nutrition intake between elderly residents in their 80’s of areas in Jeollanam-do that are well known for longevity and those of a part of Seoul. Structured in-depth interviews were conducted by trained interviewers on 125 consented subjects (67 Jeonnam and 58 Seoul). Differences of groups were tested using Chi-square tests for nominal or ordinal data and t-tests and ANOVA tests for ratio data. The elderly from Jeonnam tended to sleep longer, express emotion more freely, and interact with others more often than those from Seoul. The elderly tended to prefer sweet or salty tastes, which might be highly related to serious health problems. The most frequently consumed foods were napa cabbage kimchi (2.19 times/day) and multigrain rice (1.99 times/day). Elderly from Jeonnam tended to consume garlic, milk, beans and roasted barley/corn teas less often; whereas, they consumed porridge, dried radish greens, potato, fermented fish, dried fish, pork rib, pork belly, soybean paste soup, soybean paste/Ssamjang, other kimchis, pickled vegetables, snacks, cookies, and green/black teas more often than elderly residents from Seoul. Differences in nutrition intake between the regions were greater than differences between the perceived levels of household economic status. NAR and INQ for folate were lower among elderly from Jeonnam than those from Seoul, while those for protein, vitamin C, niacin, vitamin B6 were higher. The study results indicated that elderly from Jeonnam engaged in a more diverse diet than the elderly from Seoul.

This study was analyzed to provide fundamental data of food safety education way on the recognition, knowledge and purchase attitude of GMO foods. Data was collected from 270 University students in the Gyeong-gi region through a self-administered questionnaire. According to the results of the reliability and factor analysis, the knowledge and purchase attitude of GMO foods showed 0.742 and 0.832 in Cronbach alpha coefficient, 0.791 and 0.831 in KMO. There were significant differences in the recognition and intake possibility and purchase will, safety and absorption to a GMO foods between the specialty person and non-specialist (p<0.05). By the kind of GMO foods it appeared highly by the order corn (70.0%), tomato (67.5%), beans (63.3%) and potato (51.3%). There were significant differences in the general knowledge of GMO foods (p<0.05), whereas no significant differences in question ‘There were no genes in ordinary beans’ by a presence of a specialty (p>0.05). After the purchase attitude difference to the GMO foods was analyzed by a presence of a specialty, I appeared most highly in the question to which I say ‘I think a GMO foods is ethical.’ by a negative question and ‘I think a GMO foods is mass-produced, and it's possible to make a food problem decrease.’ by an affirmative question. Therefore, the purchase attitude of GMO foods showed a significant differences of University students according to their major (p<0.05). Based on this study, it is considered that provision of detailed and continuous education must be accomplished by raising the recognition of GMO foods and its acceptance level, allowing a proper understanding of GMO foods to be conveyed and assisting subjects from receiving the information they desire effectively by various education mediums.

This research study aimed to examine the seriousness related to sodium over intakes that is becoming a global issue, evaluate how the recognition of sodium-reduced products and its acceptance can influence the intention of purchasing sodium-reduced products, and generate basic data for establishment of marketing strategy of campaigns such as reducing sodium intake and commercialization of sodium-reduced products. According to the results of the research, the acceptance of sodium-reduced products significantly influenced the purchasing intention of sodium-reduced products, while the attitude towards sodium and recognition of sodium did not significantly influence the purchasing intention of sodium-reduced products. Extension of these research findings to ordinary people and the analysis of main causes that affect the recognition of sodium-reduced products and purchasing intention provide a solid basis for efficient sodium-reduction publicity and development of directions for campaigns.

Traditionally, food and medicines are considered as having common roots. That is, their energies share the same source (藥食同源), which has created a unique food culture, and nurtured a unique academic area of dietary medicine (藥膳食料 學). This study aimed to develop a desirable dietary life-style based on the oriental dietary medicine theorem originated from the schema of four qi as well as five flavors of foods (四氣五味), originated from the yin-yang and five phase theory based on a clear understanding of a modern point of view, and experimental analysis of nutrients and dietary effects of clear heat effect materials. This study can promote more healthy life-styles and prevent adult diseases by following oriental dietary medicine theory. We should develop a Yack-sun theory and dietary culture that is suitable for physical and genetic health.

To investigate the preference of food of the elderly for developing processed elderly food, this study was conducted from February 2014 to March 2014 by questionnaire including dietary behaviors, food preference, and frequency of food intake to 119 elderly (49 males and 70 female) who were more than 65 years old and living in Jeonju. Most subjects ate three meals regularly and most of the subjects’ favorite meal time was lunch. The duration time of one meal was 20 min (48.74%). The most preferred taste was delicate and sweet. The subject preferred cooked rice with multi-grains, kalguksu (hot noodle), and abalone porridge to other staple foods. Almost 50% of the subjects liked soybean paste soup and stew, and the ratio of elderly who liked Chinese cabbage kimchi was 72.3%. Preference for panfried foods leaned toward pan fried fish fillet and mung bean pancake. Most subjects preferred plant foods like vegetables, lettuce, and seaweeds. The elderly in Jeonju liked roasted pork, grilled yellow croaker, and stir-fried octopus. Cooked and seasoned vegetables (namul) were the most preferred type by the elderly. Preferences for dishes and food materials were not affected by sex and ages. Most subjects preferred eating out with Korean food. Preference for eating food was selected in grilled beef ribs, a pork cutlet, sushi·broiled eels, and Chinese noodles. Western Japanese and Chinese food were preferred by an elderly subject, who was male and who liked Japanese food more than female.

The purpose of this study was to examine the difference in nutritional knowledge and food preferences according to foodrelated lifestyle among 400 married women. Using the K-average clustering method, food-related lifestyles of subjects were categorized into three clusters: rational and diversity-oriented group, convenience-oriented group, and health-oriented group. The nutritional knowledge level and food preferences among three clusters were compared to each other using ANOVA test. The findings were summarized as follows: For the nutritional knowledge level, health-oriented group showed the highest mean score, whereas the lowest score was detected in the convenience-oriented group. The convenienceoriented group showed higher preferences for fish, meat, eggs, fruits, milk/dairy products, seaweed, grains, etc. among natural food than the other groups. Meanwhile, the rational and diversity-oriented group preferred legumes, and green vegetables, whereas the health-oriented group showed preferences for other vegetables. However, the convenience-oriented group reported more preferences for breads, noodles, pancakes, fried/stir-fried food, and processed food such as sausage, ham, and fast food, This study found that nutritional knowledge level and food preferences were significantly different according to food-related lifestyles of married women living in Seoul and Gyonggie areas. Thus, it is suggested that nutritional education targeting married women needs to be carefully designed by considering their food-related lifestyle.

가열하지 않은 간편섭취 농산물의 섭취를 통한 세균 감염의 가능성을 줄이고자, 가정에서 쉽게 구할 수 있고 잔류에 대한 염려가 없는 천연 항균성 식품을 이용하여 세척할 경우, 물 세척에 비해 세균의 감소효과가 있는지 확인하고자 하였다. 여러 가지 항균성 식품성분 중 마늘의 allicin, 생강의 gingerol, 녹차의 catechin, 계피의 cinnamic aldehyde, 고추냉이의 allyl isothiocyanate의 단계별 희석액으로 세척한 후, 단순 물 세척의 세척효과와 비교한 결과, 단순 물 세척에 비하여 세균 감소의 효과가 큰 것으로 통계적으로 확인되었다. 간편섭취 농산물에서 검출된 Bacillus cereus 오염의 유래 및 연관성을 확인하고자 유전적 상관성을 분석해 본 결과 유사도가 매우 높은 균주들이 많이 검출되었다. 이 사실을 통해 간편섭취 농산물의 생산, 가공, 포장, 유통 등의 과정에서 공통적인 요인에 의한 지속적인 오염의 가능성 및 소비자의 감염 가능성을 파악할수 있었으며, 감염을 예방하기 위한 사전적이고 체계적인 관리가 필요함을 확인하였다.

We evaluated the antioxidant properties of adzuki beans and the quality characteristics of sediment using various cultivation methods. There were significant differences in total polyphenol and flavonoid contents in beans grown using different methods of cultivation (p<0.05). Also, DPPH and ABTS radical-scavenging activities were significantly different depending on cultivation method (p<0.05). The sediment yield before drying of Chungju-pat, Hongeon, and Arari was 296.64~339.01, 271.36~282.24, and 268.21~292.32%, respectively, and the sediment yield after drying was 71.68~85.41, 77.90~85.19, and 74.15~78.65%, respectively. The L-value of Chungju-pat and Arari sediments revealed a significant difference given different cultivation methods (p<0.05), but Hongeon sediment did not show a significant difference. There was a significant difference in the a- and b-value of adzuki bean sediments cultivated using different methods (p<0.05). The particle size of Chungju-pat, Hongeon, and Arari sediments was 66.21~98.80, 61.62~97.07, and 82.96~106.71 μm, respectively, and all were significantly different depending on cultivation method (p<0.05). There were also significant differences in the water absorption index, water solubility index, and swelling power when different cultivation methods were used (p<0.05).

This study aimed to evaluate the efficacy of the antioxidative and antidiabetic activities of the flowers, leaves, and roots of the Jerusalem artichoke (Helianthus tuberosus L.). The total polyphenol and flavonoid contents of the leaves were higher than those of the flowers and roots. However, the DPPH radical-scavenging and hydroxyl radical-scavenging activities of the flowers were higher than those of the leaves and roots. The nitrite-scavenging ability under acidic conditions was high in Jerusalem artichoke flower extracts. The α-glucosidase inhibitory activity and α-amylase inhibitory activity of a methanol extract of Jerusalem artichoke roots were about 60% (5 mg/mL concentration). Based on these experiments, it can be concluded that the flowers leaves, and roots of the Jerusalem artichoke can be used as natural preservatives. Therefore, they can be developed as functional foods, to take advantage of their antioxidant activity and abundant polyphenols. This study suggests that the whole Jerusalem artichoke, including roots, leaves, and flowers, is useful as a functional, nutritious food product.

In this study, we investigated protection motivation and behavioral intention to prevent serious illnesses related to excessive sodium intake among the university students in Gyeongnam and Busan. Within the protection motivation theory (PMT) framework, a survey questionnaire was developed to measure participants’ perceptions on the severity of and the vulnerability to the threat of serious diseases due to the high sodium intake as well as the effectiveness of preventive measures (response efficacy), and the ability to perform them (self-efficacy) along with their willingness to follow recommendations (behavioral intention). Data was collected in June 2015. Study participants were divided into either low (n=117) or high (n=177) sodium intake behavior groups based on their current behaviors. Exploratory factor analysis was performed to measure construct validity and Cronbach’s alpha was calculated to check reliability of measurement items. The high sodium intake behavior group perceived higher vulnerability than the low sodium intake behavior group among four PMT factors. Differences of the other three factors were not significant between the two groups. The results of hierarchical regression analysis indicated that self-efficacy and response efficacy affected behavioral intention of high sodium intake behavior among students. Hence, development of strategies to increase self-efficacy and response efficacy are strongly recommended.

The purpose of this study was to analyze the food-related lifestyle choices of female baby boomers and to investigate variables regarding home meal replacement (HMR) buying behaviors and future needs. This study was conducted on 358 female baby boomers 53 years of age living in Gyeonggi and near Seoul. Out of 420 distributed questionnaires, 358 were returned and used for analysis (response rate: 85.2%). As a result of cluster analysis, three groups were identified based on the food-related lifestyles : a value-seeking group, a convenience-seeking group, and a health-seeking group. Among the three groups, there were significant differences in two socio-demographic characteristics, education level (p<0.05) and regular exercise (p<0.01), and in several health- and food-related habits, type of breakfast (p<0.01), type of dinner (p<0.05), dinner details (p<0.05), frequency of eating out (p<0.05), and eating habits score (p<0.01). The health-seeking group was significantly more likely to purchase ready to cook (RTC) items (59.1%) than were the other groups (p<0.001). However, the ratio of HMR purchasing for the purpose of meal replacement (p<0.05) and an HMR purchasing frequency of more than twice a week (p<0.001) were significantly lower in the health-seeking group. Reasons for selecting HMR showed a similar tendency among groups in taste (26.2%), convenience (18.7%), price (16.9%), safety (15.3%) and type of food (14.3%). However, the satisfaction scores for hygiene and safety reported by the health-seeking group were significantly lower than those reported by the other groups. More than two-thirds of all respondents were willing to purchase HMR in the future, though there were significant differences according to group: convenience-seeking group, 73.1%, health-seeking group, 70.1%, and value-seeking group, 65.7% (p<0.05). Our results suggest that the number of baby boomers purchasing HMR products will continue to grow and baby boomers will want HMR products to be more healthy (52.0%), safe (28.5%) and delicious (13.4%). An emphasis on taste was high in the convenience-seeking group, whereas an emphasis on health was high in the health-seeking and value-seeking groups. In conclusion, this study shows various food-related lifestyles amongst female baby boomers and illustrates the need to develop HMR marketing strategies targeted to these different lifestyles.

The objective of this study was to increase starch extraction efficiency from domestic potato by five kinds of foodgrade cellulases (mixture of β-glucanases, pectinase, cellulase, hemicelullase, and β-glucosdiase). Cellulase-treated potato had a maximum of 40% higher starch extraction yield than non-enzyme treated potato. It turned out that the shape and structure of cellulose-treated and nonenzyme-treated potatoes were the same. The average particle size of cellulose-treated potato starch was smaller than non-enzyme treated potato. Interestingly, the small starch granular (<10 μm particle) was shown in extracted starch from cellulose-treated potato. Rapid viscosity analysis showed that starch from cellulase treated potato had lower pasting temperature than starch from nonenzyme-treated potato. The range of the gelatinization temperature (49-62oC) of starches from cellulose-treated potato was broader than that of starches from nonenzyme-treated potato. Therefore, the results of this study confirm that cellulase plays an important role in the extraction of starch from the potato and physicochemical characteristics of potato starch.

Propolis possesses antimicrobial, anti-inflammatory, anaesthetic and immunostimulating activities. The aim of this study was to evaluated chemical composition and in vitro anti-Helicobacter pylori activity of eight propolis ethanolic extracts form different region in Korea. The chemical composition of eight Korean propolis was investicated by absorption spectrophotomety and UHPLC. Total penolic and total flavonoids content ranged between 21±1.5 and 31±1.8 gallic acid g/100 g and 7.2±0.9 and 24.4±1.9 quercetin g/100 g, respectively. The p-coumaric acid as standard components content ranged between 0.29±0.00 and 2.34±0.02 mg/g using UHPLC. Cinnamic acid content between 0.43±0.00 and 1.33±0.01 mg/g. 80% ethanolic extract of propolis against H. pylori was evaluated by using the disc diffusion method. Ethanol was used as a control. Mean diameters of H. pylori growth inhibition using 10 μg/mL, 50 μg/mL or 100 μg/mL ethanol propolis per disc were 0, ranging from 0.9 to 2.1 mm and from 1.9 to 3.5 mm, respectively. In conclusion, variation in the chemical composition of Korean propolis were mainly due to the difference in the preferred regional plants visited by honeybees. Also Korean propolis possesses considerable antibacterial activity against H. pylori. There was not confirmed a correlation between the chemical composion contens and anti-H. pylori effect. The potential of propolis in the prevention or treatment of H. pylori infection is worth further extensive evaluation.

Deseeded jujubes are commonly consumed as snacks. This study was conducted to develop a seed-removing machine for jujubes that relieves hard work in manual seed removal. The seed-removing machine consists of a jujube supplying unit, a punching unit, and a discharging unit. To test the performance of the machine, shape characteristics, seed removing rate, sarcocarp cracking rate, and flesh hardness were analyzed throughout the jujube storage period. The machine showed good seed removing and sarcocarp cracking rates at room temperature and cold temperature storage on days 2, 15, and 50. Seed removing rates were 80% at day 15 and 96% at day 50. The sarcocarp cracking rates were 33% for day 15 and 30% for day 50. Hardness started to decrease from day 8 to day 70 at both room temperature and cold temperature storage. The working capacity of the machine was 900 fruits/h. The results showed that the jujube seed removing machine is useful for reducing the labor requirements of postharvest jujube processing.

In this study, the texture, nucleotide-related compounds, and sensory characteristics of dry-aged beef, made from third quality grade Hanwoo beef (Korean native cattle), were investigated according to aging periods. Loin cuts obtained from three different Hanwoos were dry-aged under the specific conditions (controlled temperatures, humidity, and air flow) during 0-7 weeks. With increasing aging periods, textures were significantly decreased after 5 weeks (hardness: from 13,264±2,033 to 7,112±1,743 g; chewiness: from 4,107±1,467 to 2,334±780) and four sensory characteristics were significantly increased after 3 weeks (texture: from 2.2±1.0 to 6.2±1.1; flavor: from 3.9±0.7 to 6.2±1.5; whole preference: from 2.5±0.8 to 6.3±1.3; purchase intention: from 3.7±1.4 to 6.0±1.5) except for color (p<0.05). On the other hand, the concentrations of IMP which is related to the umami flavor of beef were significantly decreased with increasing aging periods (from 40.44±5.97 at 0-week to 7.44±2.43 μg/ mg at 7-week) (p<0.05). These results obtained in this study could provide an useful data base for the quality control of dry-aging.

Black tomato (Lycopersicum esculentum) is known to have more β-carotene, lycopene, and vitamin C than general redcolored tomatoes. In this study, we evaluated the quality properties, antioxidant activities and sensory characteristics of black tomato cookies. Cookies were prepared by replacing 0, 1, 3, 5, and 7% of flour with black tomato powder. Density of black tomato cookies tended to be decreased between control (1.20) and 3% added groups (1.12). pH value was decreased from control (6.66) to 7% added group (5.16). Spread factor and loss rate were increased with increasing amounts of black tomato powder. Hardness was gradually increased from 107.77 g/cm2 in control to 170.50 g/cm2 in 7% added group. Color measurement indicated that L-value (brightness) was highest in control (70.46) and lowest in 7% added group (45.23); whereas, a-value (redness) increased while b-value (yellowness) tended to decrease with increasing amounts of black tomato powder. Total polyphenol contents and DPPH radical scavenging activities were directly proportional to the amount of black tomato powder. Consumer preference scores in color and flavor of black tomato powder added group were higher than those of control. Characteristic strength test was not significantly different among the groups. Overall, the results indicated that adding 5% black tomato powder is desirable for making black tomato cookies.

The overconsumption of dietary salt is recognized to play a negative effect on human health such as increasing blood pressure. The purpose of this study is to investigate the effect of hydrolyzed anchovy products (HAP) on the salty taste of dried noodle. The physicochemical properties and sensory test of dried noodle were determined at different concentrations of HAP. The lightness of the noodle samples was decreased with increasing levels of HAP whereas their redness and yellowness were increased. There were no significant changes in hardness and texture properties by HAP concentration, compared to those of the control. From the sensory evaluation, the 25% and 50% HAP samples showed a high score on saltiness, preferredness, and overall taste acceptability. Consequently, the HAP could be utilized in dried noodles or cooked noodles as a salt enhancer without significantly altering the charateristics of noodles.

Celastrol은 미역줄나무의 뿌리에서 얻은 추출물로 오래전부터 관절염 및 자가면역 같은 염증반응 질병들을 치료하기 위하여 쓰여져 왔다. 이외에도 많은 연구들에서 celastrol이 신경보호, 항산화 및 알츠하이머 치료에 사용될 수 있으며 특히, 암 치료에 효과적이라고 밝혀 졌다(Table 1). 따라서 많은 연구자들이 생리학적, 생화학적 및 면역학적 관점에서 celastrol의 항암효과를 규명하고자 노력을 기울이고 있으며, 다양한 관점에서 신호전달체계를 조절한다는 사실을 밝혀냈다(Fig. 1). 특히, celastrol은 NF-κB 를 억제함으로서 암의 발달 및 전이를 저해함을 물론, 암의 치료에 동반되는 면역 반응을 조절 할 수 있다(Fig. 2). 또한 세포사멸과 관계된 유전자들을 활성화 시키고, 항세포사멸 유전자들을 억제시킴으로서 세포 주기를 조절한다. 유전자 조절 외에도 heat shock protein과 같은 단백질의 변조와 자가소화작용(autophagy)를 유도한다. 이처럼 celastrol의 다양한 효과는 암의 성공적 치료에 한발 더 가까워지게 만든다. 이외에도 celastrol의 항 비만 효과가 알려지면서 향후 비만 및 비만과 연계된 암 환자들이 가질 수 있는 부작용, 오남용 및 비용절감 측면에서 좋은 결과를 나타낼 것이라 예상 된다. Celastrol의 다양한 기작이 밝혀짐에도 불구 하고 직접적인 결합 부위에 대한 연구 결과는 아직 없으며, 임상적용 하기에 앞서 다양한 동물모델 in vivo 실험이 필요하다. 또한 임상치료 시도에 있어 안전성을 확보 하기 위해서는 celastrol의 단기간 및 장기간의 효과에 대한 깊은 연구가 요구된다.
