BACKGROUND/OBJECTIVES: The commercial foodservice industry in Korea has shown rapid growth recently. This study examined Korean adults' consumption of commercially-prepared meals based on where the food was prepared. SUBJECTS/METHODS: Data from a 24-hour dietary recall of the 2001 and 2011 Korea National Health and Nutrition Examination Surveys were analyzed. A total of 10,539 subjects (n = 6,152 in 2001; n = 4,387 in 2011) aged 19-64 years were included for analysis. Commercially-prepared meals were classified into four food source groups based on where the food was prepared: Korean restaurants, Chinese/Western/Japanese restaurants, fast-food restaurants, and retail stores. Subjects' energy intake, including the amount and proportion of calories, was examined for each food source. The analysis was also conducted by gender for age-stratified groups: 19-29, 30-49, and 50-64 years old. RESULTS: Korean adults' energy intake from commercially-prepared meals increased in the amount of calories (551 kcal to 635 kcal, P < 0.01), but not in the proportion of daily calories (27% to 28%) from 2001 to 2011. The most frequent food source of commercially-prepared meals was Korean restaurants in both years. The amount and proportion of calories from retail stores increased from 83 kcal to 143 kcal (P < 0.001) and from 4% to 7% (P < 0.001), respectively, during the same period. Males aged 30-49 years (34%) and females aged 19-29 years (35%) consumed the highest proportion of daily calories from commercially-prepared meals in 2011. CONCLUSIONS: Korean adults consumed about one-fourth of their energy intake from commercially-prepared meals. In particular, males aged 30-49 years and females aged 19-29 years consumed more than one-third of their energy intake from commercially-prepared meals. Korean restaurants played a significant role in Korean adults' energy intake. Retail stores increased influence on Korean adults' energy intake. These results could be useful for developing health promotion policies and programs.

In accordance with changes in life style, people's desire to eat out is getting changed in their preferring factors from whether they can buy food they want to eat fast and easily to mood of the dining space, content and quality of service, hygiene condition of restaurant, quiet location and surrounding circumstance, and discount coupon and price destruction. In addition, consumers who begin to recognize the seriousness of environmental pollution prefer health-oriented food. On the other hand, excessive presence of competitors, growing personnel expense, increasing expenditure in accordance with swelling price of rent and material expenditure, increase of tax burden, decrease of income because of credit card service charge and high expected level by consumers make it difficult for restaurant's owners to manage restaurant business. Therefore, this study purposes to establish development of menu from the consumer's and the supplier's point of view and propose how to develop menu aiming at convenience, health and diversity.

The coffee industry has grown very fast ever since international coffee brands were launched in the 1990's. Recently, consumers have begun to focus on coffee produced ethically. This phenomenon is due to ethical-consumption consciousness, which consists of three factors, emotional value, social value and function value. Most studies on this topic have focused on consumers who purchase fair-trade coffee. Thus, this study is novel in its focus on baristas who sell fairtrade coffee in their shops as well as differences from former studies. The three factors of ethical-consumption consciousness of baristas affected the sale of fair-trade coffee, except for the function value. Therefore, the sale of fair-trade coffee could be influenced by ethical-consumption consciousness of baristas. This study shows that education of baristas can promote the sale of fair-trade coffee. However, there are limitations as it only researched coffee brands ranked in the top 5, so further studies will be required in the future.

Human melanocortin-4 receptor (hMC4R) among MC-Rs, expressed in the brain, is in charge of the control on energy homeostasis and food intake. The structure and function of human MC4R have been studied to understand their essential function and roles. To investigate the structure and function, it is necessary to prepare sufficient amounts of proteins. However, their expression and purification is demanding and time-consuming due to their innate insoluble and toxic properties. The heterozygous mutations of hMC4R, exchange of Asp 90 to Asn located in second transmembrane, cause severe obesity in human. To obtain purified hMC4R wt-TM2 for structural studies, it was first over-expressed and purified by fast protein liquid chromatography (FPLC) and then solution NMR studies were performed to get high-resolution spectra. In here, we established optimized purification scheme to get more purified target peptide.

This study was designed to determine the usability of lemon fiber (LF-2%, 4%, 6%) and carrot fiber (CF-2%, 4%, 6%) to produce lowfat beef hamburgers. To that end, a certain amount of fat was replaced with each fiber. The proximate composition, pH value, cholesterol content, cooking characteristics, color, texture profile, and sensory properties of low-fat beef hamburgers were investigated. LF increased moisture content and cooking yield due to its better water binding properties, while CF caused higher fat and cholesterol contents owing to its higher fat absorption capacity (p<0.05). LF resulted in a lighter, redder, and more yellow color (p<0.05). Hardness, gumminess, springiness, and chewiness parameters decreased when the usage level of both fibers increased (p<0.05). However, more tender, gummy, springy, and smoother hamburgers were produced by the addition of CF in comparison with LF (p<0.05). Moreover, hamburgers including CF were rated with higher sensory scores (p<0.05). In conclusion, LF demonstrated better technological results in terms of cooking yield, shrinkage, moisture retention, and fat retention. However it is suggested that CF produces better low-fat hamburgers since up to 2% CF presented sensory and textural properties similar to those of regular hamburgers.

본 연구에서는 한식당에 대한 외국인 고객의 가격민감성을 측정하였으며, 그 결과 한식당 유형별로 가격민감성이 다르게 측정되어 가격이 각 외식업체의 제품과 서비스의 품질과 가치를 특징짓는 것으로 나타났다. 이에 따라 소비자의 서로 다른 요구에 의해 준거 가격이 복잡해지며, 소비자의 구매 목적에 따라서도 영향을 미치는 것을 알 수 있었다. 특히, 외국인 국적별로 가격민감성을 비교한 결과, 각 세분 시장별로 가격민감성에 차이를 나타냈는데, 전반적으로 일본인이 다른 세분시장에 비해 가격에 민감한 경향을 보이는 것으로 측정되었다. 이러한 가격민감성측정 모델은 다른 타겟 시장의 민감성과 각각의 수용가격범위를 측정할 수 있으므로, 외식업체 운영자들은 어떤 시장이 얼마의 최소한의 가격으로 구매 행동을 하지 않으며, 어떤 시장에 그 가격에 맞는 가치를 제공하도록 노력을 기울일 것인지 파악해야 한다. 또한 가격과 품질사이의 단순한 상관관계에 의해서만 소비자들의 행동을 설명하기 엔 너무 많은 변수들과 상황이 존재하고 있다. 따라서 구매 동기,사회적 환경 등의 요인, 시간제한, 계절적 효과, 물리적 환경, 구매 주체, 분위기 등의 상황적 변수들이 가격 민감 행동과 상호 작용 가능한 잠재적 요인들이므로 가격민감성과의 상관관계 분석도 가능할 것이다. 그러나 가격은 동질적인 제품 또는 동질적인 상황에서 소비되는 제품과 서비스에 대해서는 그 중요성이 떨어지고, 브랜드가 품질의 지각과 가치의 지각, 그리고 구매의도에도 긍정적인 영향을 미치게 되므로 외식기업들은 궁극적으로 이러한 순간에 다른 브랜드와 차별화 될 수 있는 한식 브랜드 요인들을 강조하여 경쟁적인 이익과 이윤을 증가시켜야 함을 잊지 말아야 할 것이다. 이와 함께 소비자의 기호와 욕구를 충족시킬 수 있는 가격과 가치 부여만이 고객 만족과 재 방문, 나아가 충성 고객을 이끌 수 있으며, 외식기업의 이를 활용한 가격전략 수립이 우선되어야 한다.

Brazil is considered as a great broiler feet exporter, especially for the Chinese trade. Contact lesions at the tibiotarsal region are responsible for economic losses and there is no model for its classification, thereby this study presents a fast and practical grade system to be used in the poultry industry and proposes these lesion characterizations into three different grades. For this, correlation was made between macroscopic, histological findings and microbiological quantification (Escherichia coli, Staphylococcus spp., Streptococcus spp. and sulphite-reducing clostridia) from contact lesions in the tibiotarsal region of 112 broiler carcasses, divided in four groups (n=28), accordingly to the lesion's intensity. There were no significant differences in microbiological quantification among the groups (p>0.05) except for the grade 3 group, as grade 1 and 2 lesions were in the early stages and histopathological changes such as ulceration were not observed. In grade 3 lesion group, it was observed bacterial cocci grume and ulceration at the articular region and significantly higher microbiological count (p<0.05) for E. coli and Staphylococcus spp. In conclusion, the visual standard proposed in this work, correlated and confirmed by the histopathologic, and microbiologic characterization, allows to precise and fast ascertainment of the contact lesion grade in the tibiotarsal regions of broiler carcasses. Moreover, it should be highlighted that grades 1 and 2 alterations are not caused by an inflammatory process caused by pathogenic agents and should not be considered a public health risk.

Food adulteration is a serious consumer fraud and a matter of concern to food processors and regulatory agencies. A range of analytical methods have been investigated to facilitate the detection of adulterated or mis-labelled foods & food ingredients but most of these require sophisticated equipment, highly-qualified staff and are time-consuming. Regulatory authorities and the food industry require a screening technique which will facilitate fast and relatively inexpensive monitoring of food products with a high level of accuracy. Near infrared spectroscopy has been investigated for its potential in a number of authenticity issues including meat speciation (McElhinney, Downey & Fearn (1999) JNIRS, 7(3), 145-154; Downey, McElhinney & Fearn (2000). Appl. Spectrosc. 54(6), 894-899). This report describes further analysis of these spectral sets using a hierarchical approach and binary decisions solved using logistic regression. The sample set comprised 230 homogenized meat samples i. e. chicken (55), turkey (54), pork (55), beef (32) and lamb (34) purchased locally as whole cuts of meat over a 10-12 week period. NIR reflectance spectra were recorded over the wavelength range 400-2498nm at 2nm intervals on a NIR Systems 6500 scanning monochromator. The problem was defined as a series of binary decisions i. e. is the meat red or white\ulcorner is the red meat beef or lamb\ulcorner, is the white meat pork or poultry\ulcorner etc. Each of these decisions was made using an individual binary logistic model based on scores derived from principal component or partial least squares (PLS1 and PLS2) analysis. The results obtained were equal to or better than previous reports using factorial discriminant analysis, K-nearest neighbours and PLS2 regression. This new approach using a combination of exploratory and logistic analyses also appears to have advantages of transparency and the use of inherent structure in the spectral data. Additionally, it allows for the use of different data transforms and multivariate regression techniques at each decision step.
