In order to develop new types of product which can offer a sanitary and preservative duality, and convenience to consumers in marketing and cooking particularly in urban area, two processing methods of ready-to-cook food materials with dark fleshed fishes like sardine and mackerel were investigated. A method applied, in this work, is processing of ready-to-cook sardine meat "surimi" in which sardine meat is treated with alkaline solution to stabilize myofibrillar proteins, washed thoroughly with water to remove soluble components, and added with a proper amount of polyphosphate and sorbitol to enforce the functional property of meat such as water holding capasity, elasticity, and gel strength. The textural properties of fish meat paste made from the "surimi" meat were greatly dependent upon the stability of myofibrillar proteins and the elimination of water soluble components. The salt soluble proteins of sardine meat were so unstable in post-mortem stage that the gel forming ability was lost within 3 days at $5^{\circ}C$ storage and 2 to 3 weeks even at $-20^{\circ}C$ although the freshness was well kept for a week at $5^{\circ}C$ and several months of storage at $-20^{\circ}C$. A proper way of treatment to keep the proteins stable was that fish meat must be washed with $0.4\%$ sodium bicarbonate solution followed by 3 to 4 times washing with water. This resulted in removal of $80\%$ water soluble proteins and 50 to $60\%$ lipids. The addition of polyphosphate and sorbitol affected the stability of proteins during the storage of "surimi" meat. When phosphate and sorbitol were added in the ratio of $0.3\%:\;0.3\%,\;0.6\%:\;3\%,\;0.6\%:\;6\%,\;0:\,0.3\%\;and\;0.3\%:\;0$, the gel forming ability terminated in 35 days, 21 days, 14 days, 14 days, and 14 days of storage at $-30^{\circ}C$, respectively, while that of the control was 7 days. And it was also noteworthy that at least 8.0 mg/g of salt soluble protein nitrogen content was required for gel formation.

In 2007, due to the outcome of the Korea-U.S. FTA negotiations, the opportunities for American beef greatly increased and a serious change in the domestic dining market is expected. The market currently faces issues such as the settlement of the beef origin declaration policy and the fulfillment of customer needs on domestic and imported beef. The following are the summary of the results of the aforementioned research and analysis. First, the consumer awareness level of origin declarations was comparatively low. Second, the reason behind the propensity for imported beef was the comparatively cheaper price despite the lower taste quality, and it was determined that there is a high level of distrust on domestic beef sold in general restaurants. Third, domestic beef showed a high valuation in taste, safety and freshness, while imported beef showed results which were below average. Concluding from the above research results, a dining environment should be created where consumers can trust what they eat through settlement of an origin declaration policy, and more efforts should be put into fulfilling consumer needs for both domestic and imported beef.

Trimethylamine (TMA) is an organic amine gas that serves as a key indicator for evaluating the freshness of seafood. We synthesized a highly sensitive trimethylamine (TMA) sensor based on porous indium oxide (In₂O₃) nanoparticles (NPs) loaded with CuO in the range of 6.7 to 28.4 at.%. CuO was loaded by hydrazine reduction onto as prepared In₂O₃ NPs using the microwave irradiation method. Crystal structures, morphologies, and chemical composition of CuO/In₂O₃ nanostructures (NSs) were characterized by X-ray diffraction, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and inductively coupled plasma mass spectrometry. The response of the 23.8 at.% CuO/In₂O₃ to 2.5 ppm TMA at 325℃ was 5.7, which was 2.8 times higher than that of porous In₂O₃ NPs. The high sensitivity and selective detection of TMA were attributed to electronic interactions between CuO and In₂O₃ and the high catalytic activity of CuO to TMA. Altogether, this CuO/In₂O₃ sensor could be used in the future to detect low concentrations of TMA, thereby aiding in the storage and distribution of marine food resources.

This study was carried out to investigate the flavor changes of Lentinus edodes at different storage temperatures, time and natural additives using an electronic nose with six metal oxide sensors. To preserve good quality of modified atmosphere packaged Lentinus edodes, Four natural additives(Artemisia princeps, Artemisia capillaries, green tea, and activated charcoal) were used. The mushrooms were packaged in polyethylene films with each treatment and were stored at 5, 10 and $20^{\circ}C$. Increase in storage temperature and storage time decreased the ratio of resistance in the electronic nose as well as first principal component scores. In addition, indicating quality of mushroom reduced at high temperature and long storage time. The results of the electronic nose and the principal component analysis(PCA) in the mushrooms with Artemisia princeps and Artemisia capillaries that were stored at $5^{\circ}C$, and green tea and activated charcoal which were stored at $10^{\circ}C$ showed the good effects to maintain the freshness along with reducing off-flavor. However, there were no differences between control and treatment groups at $20^{\circ}C$.

The purpose of this research was to evaluate the quality of take-out services at restaurants in Chungbuk Province. A questionnaire survey by 450 customers who had experience in take-out service at the restaurants was conducted and 378 completed questionnaires were available for statistical evaluation. Statistical analyses were made of raw data by SAS V8.2. The scale for analyzing the importance and performance of the service quality was composed of 5-point Likert scales. The main results of this study are as follow: The quality attributes of take-out service were rearranged into four factors in terms of food, sanitation, access and service. The importance score was higher than performance score. IPA showed that 'freshness of food material', 'cleanliness and hygiene in food', 'sanitation of facilities', 'neatness of employees' and 'price in food' was included in 'focus here' area. There was significantly positive correlation between factors such as food, sanitation, access, service and overall customer satisfaction (p<.001); between factors and repurchasing intentions (p<.001); and between customer satisfaction and repurchasing intentions (p<.001). According to multiple regression analysis, 26.27% of the variance in respondents' overall satisfaction score and 9.21% of the variance in respondents' repurchasing intention score could be explained by factors such as food, sanitation, access and service.
