One of the most important the success of a food service organization. As a matter of fact, menu functions as a list of product restaurant and a communication tool that facilitates the communication between a restaurant and its customers. Accordingly, many scholars and practitioners have suggested various for menu analysis. Among others, menu analysis methods proposed by Miller, Kasavana & Smith, and Pavesic have been frequently and repeatedly published in the academic literature. However, methods common limitation utilize a two-dimensional approach quadrants. Focusing on this problematic of traditional menu analysis methods, Hayes & Huffman suggested a new menu analysis method goal value analysis. The of this study to the menu analysis technique suggested by Hayes & Huffman using goal value. In this research, the goal value analysis adopted wine restaurant.

Changes in the various quality characteristics of hamburg steak depending on the packaging methods were investigated during storage at $5{\pm}1^{\circ}C$ for up to 15 days. Three packaging treatments including vacuum packaging (VAP), air-containing packaging (AC), and oxygen scavenger packaging (OS) were applied in this experiment. The initial total aerobe bacteria counts were identical at 2.3 log CFU/g in all treatments, but the growth rate of total aerobe bacteria in the AC samples was significantly faster than the VAP and OS samples during storage. The changes in the TBA and VBN values over the storage time showed that lipid oxidation and protein spoilage developed fastest in the AC sample, followed by OS and then VAP samples. The instrumental color and texture profiles were not significantly differ between treatments during storage (p>0.05). After 12 days of storage at $5^{\circ}C$, evaluation of the samples' sensory attributes showed that the AC samples had become unmarketable with a score of less than 5.0 points for all sensory properties, whereas the VAP and OS samples were still marketable.

The objective of this study was to evaluate the combined treatment effect of gamma irradiation and rosemary extract powder on ready-to-eat hamburger steaks. After irradiation at 5, 10 and 20 k㏉, hamburger steaks manufactured with rosemary extract powder (200 and 500 ppm) were stored at 5$^{\circ}C$ for 4 months and at 3$0^{\circ}C$ for 3 weeks. Total aerobic bacteria count of the ready-to-eat hamburger steak was approximately 5 log CFU/g level. All doses of gamma irradiation were effective in reducing the population of total aerobic bacteria and coliform bacteria in hamburger steaks. In hamburger steaks irradiated at 20 k㏉, tile microbial growth was not observed during storage. The shelf-life of hamburger steaks were determined by microbiological counts of 10$^{6}$ ∼10$^{7}$ CFU/g and those of the steaks irradiated at 0, 5 and 10 k㏉ were ranged among 14, 28∼42 and 98∼112 days, respectively. The shelf-life of both irradiated hamburger steaks added with 500 ppm rosemary extract powder at 5 and 10 k㏉ was extended more 14 days than non-added sample. Results suggested that both gamma irradiation and rosemary extract powder may improve the shelf-stability of ready-to-eat ham-burger steak. However, when the storage temperature was abused (3$0^{\circ}C$), the rosemary extract powder had not sufficient effect on the shelf- stability of hamburger steaks.

Volatile compounds of kimchi-flavored steak sauce were isolated using simultaneous steam distillation and solvent extraction methods and identified by matching mass spectrum and retention index (RI) with the reference data. Twenty-three compounds including five aldehydes, four alcohols, four acids, three sulfur-containing compounds, one ketone, and six others were identified, among which the most abundant compound was eugenol. Sulfides such as dimethyl dis- and trisulfides, and acids such as acetic and dodecanoic acids showed strong effects on the kimchi flavor. Aroma extract dilution analysis with three fold dilution factor shown in over the FD value 34 identified 2-butanal, 2-pentylfuran, methyl-2-propenyl disulfide, and 2-furanmethanol. Strong good aroma was detected in the RI range between 1030 and 1357, bad aroma in RI 1561, sweety aroma in RI 2057, clover aroma of eugenol in RI 2122, and rancid flavor in RI 2251.

The purpose of this study was to suggest menu pricing strategy based on understanding about customer perceived value of products and services. The technique known as PSM (Price Sensitivity Measurement) was used for analysis of price sensitivity for 3 menu items of a family restaurant in Seoul. A questionnaire was developed through literature review and modified after pilot test. Questionnaires for the main survey were distributed to 250 customers on their visit to the restaurant, and a total of 138 questionnaires were used for analysis (55.2%). The statistical analysis of price sensitivity was conducted using PSM, and descriptive analyses were conducted using SPSS Win (12.0). The main results of this study were as follows: the price sensitivity of beef tenderloin steak was higher than two other menus and the stress range of teriyaki chicken was almost 0, that is, the price sensitivity of teriyaki chicken was very low. Present menu prices of 3 menu items were within the range of acceptable prices, but had some distances from the optimal pricing point. From the result of this study, it was concluded that price adjustment or price promotion strategy would be effective for increase in sales of beef tenderloin steak, and marketing strategies to enhance consumers' perceptions of value should be conducted for all menu items by situations. Overall, PSM technique could be a helpful tool for researchers and managers of foodservice organizations to understand how consumers' perceptions of value are affected by the interaction of price and quality.

Changes in proximate composition and protein quality were determined to find out appropriate processing conditions of the seasoned and smoked squid(Neon flying squid, Ommastrephes bartrannii). Moisture and crude protein contents were severely reduced (p<0.05), while increasing of fat and ash contents were not apparent. Seasoning and smoking contributed iii enhancing TBA value. Trypsin inhibitor(Tl) content was not increased severely after those processing steps. TI content checked in the all steps of squid processing was not correlated with the TBA value of squid in the same processing step. An improved digestibility and protein efficiency ratio(PER) were observed in the all products except with steak(mechanically soften product) in vitro enzymatic digestibilities of both raw Neon flying squid meats(mantle and arm) were significantly inferior(p<0.05) to other squid species.

Effect of slaughter age (24, 28 and 38 months of age) on beef color stability during display of m. serratus ventralis, m. psoas major, m. semitendinosus and m. longissimus thoracis from Japanese Black steers was studied. Steak samples from muscles were over-wrapped with PVC film and displayed under fluorescent lights at $4^{\circ}C$ for 12 days. Percentages of metmyoglobin of steak samples were determined at days 0, 3, 6, 9 and 12. The percentage of metmyoglobin of m. psoas major at day 3 of display in the 24 months group was lower (p<0.05) than that in the 38 months group. The percentage of metmyoglobin of m. semitendinosus at day 6 of display in the 38 months group was higher (p<0.05) than that in the other groups. The percentage of metmyoglobin of m. longissimus thoracis at day 3 of display in the 24 months group was lower (p<0.01) than that in the other groups. The percentage of metmyoglobin of m. longissimus thoracis at day 6 (p<0.01), 9 (p<0.01) and 12 (p<0.05) of display in the 38 months group were higher than those in the other groups. Crude fat concentration in m. longissimus thoracis increased (p<0.05) after 28 months of age. $\alpha$-Tocopherol concentration in m. serratus ventralis in the 38 months group was higher (p<0.001) than that in the other groups. In m. psoas major the $\alpha$-tocopherol concentration in the 38 months group was higher (p<0.05) than that in the 24 months group. The $\alpha$-tocopherol concentration in m. longissimus thoracis increased (p<0.001) with age. These results suggested that in spite of increase in both the crude fat and the $\alpha$-tocopherol concentrations in m. longissimus thoracis, the beef color stability during display became short with age.
