The objective of this study was to investigate the sensory quality characteristics of coffee under various processing and roasting conditions of green beans. Colombia green bean samples were obtained from three processing methods: natural, pulped-natural, and washed methods. The green beans were roasted differently according to Agtron number: light (Agrton #65), medium (Agtron #55), and dark (Agtron #45). Moisture content, density, color value, pH, and total dissolved solid contents (TDS) were measured, and quantitative descriptive analysis (QDA) with 23 sensory attributes was performed for nine coffee samples. Hunter L values were significantly elevated with the degree of processing but reduced with roasting intensity. The pH values of the nine coffee samples were 5.6~6.2 and significantly increased with intensity of roasting. TDS decreased with an increase in processing and increased with roasting intensity. QDA results show that smoky aroma and nutty and chocolate flavor significantly increased while fruit and floral aroma decreased with intensity of processing. The attributes of brownness, oily surface, smoky aroma, bitter and burnt flavor, and greasy and heavy mouthfeel significantly increased while fruity and floral aroma, black tea, sour and umami flavor, pureness, and softness decreased as roasting intensity increased. Principle component analysis showed the overall significant relationships between 23 sensory attributes and nine coffee samples under different processing and roasting conditions.

This study aimed to estimate daily intake of anthocyanins and to identify major sources of anthocyanins in current Korean dietary patterns in order to implement dietary recommendations for the improvement of Korean health. Sixteen foods were selected based on the availability of food intake and reliable anthocyanin content. Food intake data from the Korea National Health and Nutrition Examination Survey 2014 and anthocyanin content data from earlier investigations were used to calculate the consumption of anthocyanins. Anthocyanin contents of 16 foods varied significantly and exhibited a range of 0~4,009 mg/100 g of fresh weight. Daily intake of anthocyanins was estimated to be 3.3 mg to 95.5 mg in Koreans. Of the 16 foods studied, the source contributing most to anthocyanin intake in the Korean population was plums (35.1%), followed by black beans (17.1%) and grapes (15.2%). These results indicate that major foods contributing to anthocyanin consumption in the Korean dietary pattern are fruits and grains.

We attempted to develop a seafood menu by applying the most preferred recipes to the most disliked seafood menus in order to improve elementary schoolers' seafood menu preferences and consumption levels. A survey was conducted on the attitudes of 106 fifth graders about nine cooking methods and 37 school seafood menus served in the past 2 years. The deep-frying method was the most preferred by both boys and girls. The next preferred methods by boys were grilling and batter-frying while those by girls were stir-frying and batter-frying. The most disliked menus were cold jellyfish salad, mussel soup, dried-pollack soup, and sea-snail salad in that order. Mussel soup, dried-pollack soup, and seasnails salad ranked as the least preferred menu as well. Finally, standardized recipes for mussel croquette, dried-pollack Gangjeong, and batter-fried seasnails were developed. Consumption ratios of mussel croquette (85.94%), dried-pollack Gangjeong (79.55%), and batter-fried seasnails (75.5%) were significantly improved compared to the original menu (p<0.001). For mussel croquette, satisfaction scores for serving size, appearance, flavor, texture, and taste were significantly higher, and intakes of protein, phosphorus, iron, potassium, vitamin A, vitamin B1, vitamin B2, niacin, and vitamin C were significantly improved, as compared with mussel soup (p<0.001). Dried-pollack Gangjeong, texture and taste scores were significantly improved compared to dried-pollack soup. For batter-fried seasnails, protein, phosphorus, and iron intake levels and taste score were significantly improved compared to seasnail salad. Findings of the study suggest that a combination of disliked seafood ingredients and preferred recipes may be helpful in improving elementary school foodservice by increasing menu preference and consumption ratio.

본 연구는 streptozotocin(STZ)으로 당뇨를 유발시킨 Sprague-Dawley계 수컷 흰쥐에게 4주간 삼채(Allium hookeri; AH) 뿌리를 식이에 보충한 정상대조군 normal-control(N-control)과 STZ-control, STZ-AH 5%와 STZ-AH 10% 첨가군을 당뇨실험군으로 하여 삼채의 잠재적인 항산화 식재료로써의 활용성을 확인하였다. 해당식이를 4주간 공급한 후, 간과 근육의 글리코겐, 간의 단백질과 MDA, 간의 세포질에서 XOD, GST, SOD, CAT, GR 및 GPX의 항산화효소 함량을 분석하여 다음과 같은 결과를 얻었다. 간의 글리코겐 함량은 N-control에 비해 STZ-control에서 유의적으로 낮았고, 당뇨실험군에서는 STZ-AH 5%에서 STZ-control보다 유의적으로 높은 함량 차이를 보였다. 근육의 글리코겐 함량은 N-control에 비해 STZ-control에서 유의적으로 낮았고, STZ-control에 비해 STZ-AH 5%와 STZ-AH 10%에서 유의적으로 높은 차이었다. 간의 단백질 함량은 N-control과 STZ-control에서는 유의적인 차이를 보이지 않았으나, STZ-control보다 STZ-AH 첨가군 모두에서 유의적으로 높았다. 간의 MDA 함량은 N-control보다 STZ-control에서 유의적으로 높은 함량이었고, STZ-control보다 STZ-AH 첨가군 모두에서 낮은 함량이었다. 간의 세포질에서 측정한 XOD 함량은 N-control과 STZ-control은 유의적인 차이를 보였고, 당뇨실험군에서는 STZ-control보다 STZ-AH 5%와 STZ-AH 10% 첨가군 모두에서 유의적으로 낮은 함량 차이를 보였다. GST 함량은 N-control에 비해 STZ-control에서는 유의적으로 낮았고, STZ-control 보다 STZ-AH 5%와 STZ-AH 10% 첨가군 모두에서 유의적으로 높은 함량이었다. SOD는 N-control과 STZ-control에서 유의적인 함량 차이를 보였으나, 당뇨실험군 간에는 STZ-control과 유의성을 보이지 않았다. CAT는 N-control과 STZ-control에서 유의적인 차이는 아니었으나, STZ-control과 비교하여 STZ-AH 10%에서 유의적으로 높은 함량 차이를 보였다. GR과 GPX 함량에서는 유의적인 차이를 보이지 않았다. 이상의 연구결과, 삼채뿌리 분말을 식이로 첨가하였을 때 당뇨시 간과 근육의 글리코겐과 간의 단백질 함량이 높아졌고, MDA 함량은 낮아졌다. 효소 함량은 XOD에서 낮아졌고, CAT와 GST에서 높아지는 경향이었다. 삼채는 STZ에 의한 포도당의 과부하에 의해 증가된 과산화물의 생성억제와 조직 내 세포의 산화적 스트레스 감소작용으로 생체내 항산화 방어력을 증가시킬 수 있으며, 당뇨 예방 및 치료를 위한 식사요법에 이용 가능한 식품으로 사료된다.

This study was carried out to compare the relationship between biochemical indices and bone mineral density (BMD) in 50 pre-menopausal and 50 post-menopausal women. The subjects were divided into normal and risk groups according to their bone status, as determined by T-scores of the lumbar spine and femur. The average T-score of the lumbar spine was higher (p<0.05) in pre-menopausal women ($0.42{\pm}0.18$) than post-menopausal women ($-0.08{\pm}0.21$). Serum levels of HDL-cholesterol, P, and Fe were significantly higher in the risk group than the normal group in pre-menopausal women (p<0.05). Serum levels of total protein, globulin, alkaline phosphatase (ALP), and osteocalcin were lower in the risk group than the normal group, whereas the level of estrogen was higher in the normal group than the risk group in post-menopausal women (p<0.05). In pre-menopausal women, P was positively correlated with Ca (p<0.01), and ALP was positively correlated with osteocalcin (p<0.01) and parathyroid hormone (PTH) (p<0.05). Further, insulin-like growth factor-I (IGF-I) was negatively correlated with the vitamin $25(OH)D_3$ and vitamin K (p<0.05). In post- menopausal women, the Ca was positively correlated with vitamin $25(OH)D_3$ (p<0.05) and vitamin K (p<0.01), and P was positively correlated with vitamin K (p<0.01), Ca (p<0.01), and IGF-I (p<0.05) and negatively correlated with PTH (p<0.05). IGF-I was negatively correlated with PTH (p<0.01) and estrogen (p<0.05), and ALP was positively correlated with osteocalcin (p<0.01) and negatively correlated with vitamin K and estrogen (p<0.05). In pre-menopausal women, the lumbar spine BMD was positively correlated with vitamin K level (p<0.01) and negatively correlated with P level (p<0.05). In post-menopausal women, the femur BMD was positively correlated with estrogen level and negatively correlated with PTH leves (p<0.05). These results suggest that vitamin K and P levels are associated with bone health in pre-menopausal women, and estrogen and PTH levels are associated with bone health in post-menopausal women.

This study investigated the status of Korean food consumption and the need for home meal replacement of Korean food for Chinese and Japanese in order to export Korean food to China and Japan. In total, 78.2% of Chinese and 33.0% of Japanese showed significant differences in their experiences of visiting Korea. The most common place to consume Korean food was a Korean restaurant for Chinese (55.8%), whereas Japanese (44.9%) consumed Korean food at Korean restaurants in Japan. In the purchasing experience of Korean home meal replacement, 59.2% of Chinese and 40.5% of Japanese responded that they had 'purchase experience', and the reason for purchasing was 'delicious' (32.5%) for Chinese and 'convenience' (34.8 %) for Japanese. The place to purchase Korean home meal replacement was large marts in both countries. Most Chinese (92.2%) and Japanese (62.1%) respondents said they were willing to buy Korean home meal replacement. Both Chinese (54.8 %) and Japanese (48.0%) said that 'taste' was the most important factor to consider when developing Korean home meal replacement. The favorite tastes were 'spicy' (35.3%) for Chinese and 'savory' (38.8%) for Japanese. For the taste of Korean home meal replacement, Chinese answered that the product should be developed by maintaining 'Korean traditional taste as it is' (57.7%), whereas Japanese responded 'change according to the taste of Japanese' (65.2%). For the preferred packaging form of home meal replacement, Chinese preferred 'vacuum' package while the Japanese preferred 'frozen'. The results of this study can be used as basic data for domestic food companies to establish marketing strategies to enter the Chinese and Japanese home meal replacement markets.

The purpose of this study was to analyze the effect of consumers' perceived brand benefits toward brand coffee shops on continuous purchase intentions as well as the mediating effect of brand trust. The survey was conducted on coffee consumers aged 20~40 years living in Seoul and who visited brand coffee shops exposed as product placement (PPL) in TV dramas. Out of 400 questionnaires distributed to consumers, 381 questionnaires (95.3%) were analyzed. Consumers were more interested in places (60.1%) than the products (39.9%) of the coffee shops exposed as PPL. Over half (54.6%) of the respondents showed a positive attitude towards coffee shop PPLs. All three brand benefits perceived by consumers (functional, symbolic, and empirical) had significant positive effects on brand trust and continuous purchase intention. In particular, symbolic benefit has the greatest impact on continuous purchase intention towards the brand. Brand trust had a mediating effect between perceived brand benefits and continuous purchase intentions. Therefore, it is necessary to focus on enhancing the perceived symbolic benefit of the brand to effectively maintain customer relationships. The results suggest that when planning positioning concepts, considering the importance of brand benefits is the best way to increase the competitiveness of coffee shop brands.

Adenophora triphylla var. japonica extract has been reported to have estrogenic activity and beneficial effects in postmenopausal women requiring estrogen replacement therapy. This study investigated the effects of A. triphylla extract on cognitive function in ovariectomized mice. Water extracts from A. triphylla were administrated to ovariectomized mice fed a high fat diet for 6 weeks. The step through latency time in the passive avoidance test was shortened in ovariectomized mice as compared with sham-operated mice. However, administration of A. triphylla extracts had a tendency to prolong the latency time in ovariectomized mice. Moreover, A. triphylla supplementation caused a significant decrease in mean escape latency in the water maze test. These results indicate that A. triphylla could be used to improve estrogen deficiency-related learning and memory impairments in postmenopausal women.

The purpose of this study was to investigate the levels of risk perception characteristics for food risk elements using a psychometric paradigm from 298 university students in Yeungnam region, Korea, by a self-administered questionnaire. The respondents showed the highest level of risk concern about radioactive contaminated foods and the lowest level about GM (genetically modified) foods. In the risk perception characteristics for food risk elements, they perceived radioactive contaminated foods as a catastrophic, worried, new, and uncontrollable risk. In addition, they regarded food additives and foodborne illness as a chronic, controllable, old, and scientifically and individually known risk. According to the results of the factor analysis for risk perception characteristics, dread and unknown were categorized. In the risk perception map, mad cow disease, heavy metal contaminated foods, and radioactive contaminated foods were considered as a dreaded and unknown risk, whereas pesticide residues and GM foods were perceived as a less dreaded and unknown risk. Additionally, food additives and foodborne illness were regarded as a less dreaded and known risk and endocrine disruptors and avian influenza as a dreaded and known risk. These results imply that risk perception characteristics of consumers should be considered to establish strategies for risk communication in food science.

This study provides preliminary data to help organize improvements in analyzing the importance and performance of sanitation management items and the management of foodservice facilities in Community Child Centers in Daegu and Gyeongbuk Area. Questionnaires were distributed to 173 participants in sanitation and safety education at the center from April~June 2013 and 121 questionnaires were used as analysis data to investigate the management of foodservice facility at Community Children Centers in Daegu Gyeongbuk area. Most of the Community Child Centers are privately owned, and 62.0% had 20 to 29 children. Only 6.6% and 50.4% of the centers had nutritionists or cooks, respectively, due to budget deficits, and the foodservices were run by employees holding other positions. An investigation of sanitation management found that 84.3% of employees had a regular health inspection with significant differences between Daegu and Gyeongbuk (p<0.05). Most of the sanitation education was necessary, and the contents of sanitation education were applied to the fields in 66.1% of facilities. The reasons why the contents of them were not used in the fields included, the shortage of facilities and devices at 20.7%, which was the most common explanation. The separation separated of contaminated and non-contaminated areas were observed in 45.5% of facilities (p<0.01), separated sinks for pre-processing and cooking were found in 50.4%, and a show significant higher rate was noted in Daegu than in Gyeongbuk (p<0.05). An interior wall and, floor tile installation were observed 43.8% of facilities and a significantly higher rate was noted in Daegu than in Gyeongbuk (p<0.05). 30.9% of centers in Daegu and 11.3% of centers in Gyeongbuk area were equipped with a hot holding table(p<0.05). Overall, there is a need for education of foodservice to managers because most facilities do not have dietitians. In addition, facilities and equipment should be supplied continuously to foodservice facilities in community child centers.

사회관계망서비스는 많은 분야에서 활용이 되고 있으며, 특히 식품접객업소를 이용한 소비자들이 맛이나 품질, 위생상태에 대한 평가를 사회관계망서비스에 많이 남기고, 이를 바탕으로 다른 소비자들이 이용할 식품접객업소를 선택하는 경향이 뚜렷해지고 있다. 하지만, 이러한 사회관계망서비스상의 식품접객업소에 대한 소비자의 평가와 실질적인 위생상태의 연관성에 대한 평가는 아직 이루어지지 않았다. 따라서, 본 연구는 사회관계망서비스 상의 식품접객업소에 대한 평가와 실제 식품접객업소의 음식 위생 상태와의 연관성을 규명하기 위하여 수행되었다. 국내 대표 포털사이트를 이용하여 식품접객업소를 선정하였으며, 동일 업종에 따라 대중의 평가가 좋은 업소 6곳과 좋지 않은 업소 6곳을 최종 선정하였다. 각 업소에서 제공하는 주 요리 및 반찬에 대한 일반 세균수 및 위생지표세균(대장균군, 대장균)에 대한 오염도 조사를 실시하였다. 일반세균의 검출률과 세균수는 소비자 평가에 따른 차이가 없었다. 하지만, 대장균군의 경우, 소비자 평가가 좋은 업소에서 평균 2.3 log CFU/g(검출률 62.5%), 평가가 좋지 않은 업소에서 평균 3.2 log CFU/g(검출률 70.8%)으로 나타나, 평가가 나쁜 업소에서 오염도가 높은 것을 알 수 있었다. 대장균의 경우도 평가가 나쁜 업소들이 검출률(25%)과 평균 세균수(0.8 log CFU/g)가 평가가 좋은 업소들(검출률: 8.3%, 평균 세균수: 0.5 log CFU/g)보다 높게 나타났다. 종합적으로, 본 연구를 통해 사회관계망서비스 상의 소비자 평가와 식품접객업소의 위생상태가 연관성이 있음을 알 수 있으므로, 이러한 결과를 바탕으로 국내 식품접객업소의 위생상태 점검 및 관리 시 사회관계망서비스 상의 소비자 평가 자료를 활용한다면 좀 더 효율적으로 위생상태 점검 및 관리가 이루어질 수 있을 것으로 판단된다.

The objective of this study was to analyze the relationship between blood pressure and serum mineral concentration in hypertension patients subjected to dehydration. The data were collected and analyzed for 7,109 patients who visited a hospital for their health checkup from 2011 till 2015. Respondents were classified into four groups depending upon their state of hypertension and dehydration: control group (no hypertension and no dehydrated), dehydrated group, hypertension group, and dehydrated with hypertension group. Hypertension group was found to have higher levels of serum sodium, calcium, and uric acid than the normal group, whereas the dehydrated group was found to have higher levels of serum sodium and potassium than the normal group. In effect, no significant correlation was directly observed between the hypertension group and dehydration group. However, there were significant negative correlations between dehydration of the old-aged group and their serum mineral concentrations, which are reportedly related to hypertension. Thus, dehydration prevention measures in the elderly over 65 could mitigate hypertension problems.
