In order to study the quarantine and sanitization methods for dried red pepper, comparative effects of commercial fumigation (methyl bromide/MeBr, phosphine gas/PH3 and gamma irradiation (5, 10 kGy) were investigated in terms of its physicochemical properties. There were no noticeable chances in pH and soluble solids among the untreated control, irradiated and fumigated samples soon after treatments, but some decrease was found in stored samples (especially soluble solid in fumigated samples) for 8 months under room temperature. Total sugar content was influenced by storage time rather than both treatments. Immediately after treatments, reducing sugar content was significantly reduced in the samples including pericarp when exposed to fumigants (p〈0.05), while an apparent decrease was observed in the stored samples including seeds with negligible differences among treatment groups. The electron donating ability (EDA) of the extracts was high in the order of pericarp, whole pepper, powdered pepper and seeds, which was reduced during storage for 8 months particularly in the samples containing seeds. The EDA of irradiated samples during storage was equal to that of the control sample, whereas that of fumigated samples was relatively low (p〈0.05).

This study was carried on the quality characteristics of cake prepared with Co(com oil) containing MCT(medium chain triglycerides), which is used as a fat substitute. In tile cake prepared with MCT-CO containing 10~30% MCT, the appearance and the degree of gelatinization were similar to those of cake prepared with NS-CO(non-substituted corn ell) Cake batter prepared with MCT-CO showed higher specific gravity and consistency than those of cake prepared with NS-CO and increased by increasing MCT contents. The baking loss of cake prepared with MCT-CO was more than that of cake prepared with NS-CO and increased by increasing MCT contents as well. The rheological properties of cake represented significant different by MCT substitution ratio(p〈0.05). Gumminess, hardness and chewiness of cake prepared with MCT-CO containing 20~30% MCT were about 2 times higher than those of cake prepared with NS-CO, while springiness and cohesiveness showed similar pattern between the cake prepared with MCT-CO or NS-CO. In sensory evaluation, appearance. color and flavor of cake prepared with CO substituted by MCT up to 100% were better assessed and the taste was better in range of 30% MCT-CO but the texture was less accepted than that of cake prepared with NS-CO.
시중에 유통되고 있는 조미 오징어(PVC film, 0.6 mm)의 감마선 조사와 저장 중(15±1℃, 6개월) 품질변화를 살펴보았다. 시료의 미생물 농도는 1.6×105CFU/g, 효모 및 곰팡이 104~105CFU/g. 대장균군은 음성으로 각각 나타났으나, 3kGy의 감마선 조사는 저장 6개월까지도 검출한계 이하의 감균효과를 보였다. 시료의 pH와 수분함량은 감마선 조사에 의해 영향을 받지 않았으나 저장 중 수분한량은 감소되었다. 시료의 색도(Hunter b). 지용성 및 수용성 색소와 지방질의 품질을 나타내는 TBA가는 3kGy 이상의 감마선 조사에 의해 증가하였으나 저장기간의 영향이 더 큰 것으로 확인되었다. 시료의 VBN 및 TMA 함량은 감마선 조사 시 비조사구와 유사하거나 낮은 값을 보였으며, 저장 중에는 전반적으로 증가하는 경향이나 감마선 조사구는 미생물 농도의 감소로 대조구보다 유의적으로 낮은 값을 나타내었다.
This study was conducted to identify the factors that correlated with food consumption frequency and perceptions of attributes for food selection. The purpose of this study was to improve menu's quality which is related to the food consumption frequency. Taste health and cost perceptions were chosen as the main factors of foods selection from the former related researches. There were differences in foods perception and consumption patterns according to gender. For both of female and male consumers, taste perceptions were highly correlated with consumption of most of foods. Finally, some recommendations which should be considered to correct or improve the quality of menu.
The purpose of this study was to investigate three different perceptions based on major 23 part planning attributes. These party planning attributes were categorized using exploratory factor analysis. Three groups of respondents were identified based on the sample data; the first group is a group of people experienced parties before, the second group is a group of people intended to attend parties in near future, and the third group is a group of people who want to be a party planner. Respondents participated in this study express their own perceptions on party-planning attributes. The study shows that the perceptions of respondents were significantly different from each other. Particularly, prospective party planners emphasize on artistic attributes, such as harmony between dishes and foods or between the party concept and foods. However, party attendees more importantly considered other attributes, including the event suitable to the party type, places held a party. The research suggests that understanding party attendees' perception will provide useful information to develop party events that can reflect customers' desires.
The purpose of this study is to highlight the importance of relationship marketing which has been developed as an alternative way of handling marketing in family restaurants. This study focused on the consumers' behavior - mainly their switching behavior and loyalty toward relationship marketing activities exercised by from family restaurants. 269 usable questionnaires were collected from customers patronizing three family style restaurants in Seoul. Several statistical methods were used including descriptive analysis, reliability test, covariance analysis, confirmatory factor analysis, and covariance structural analysis. The result drawn from empirical test proved that relationship marketing activities actually are the significant determinants of relationship quality and thus to the customers' behaviors toward the restaurants they patronize. Managerial implications can be drawn from the result findings that restaurant companies can identify the activities of relationship marketing to continue the long-term relationship with their customers. Also restaurant companies can use the activities of relationship marketing as differentiating strategies, and allocate their resources into the activities of relationship marketing.
This study examined dietary culture in Korea regarding collectivism through literature review. Based on the evidence from the origin of lineage and traditional customs, the Koreans' traditional collectivity appeared to have been grounded upon the northen nomadic culture emphasizing sentimental collectivity and harmonized with the characteristics of southern agrarian society related to mutual support and sociability. The inseparable relationship between collectivity and food was well revealed in the occasions such as rice-planting, kimchi and jang makings in which pooled labor was common as well as the gathering of mutual aid association. In these occasions, foods were offered and shared among members. Food sharing was a main activity and almost play a central role regarding the promotion of friendly relations among each other. In sacrificial memorials, food sharing was extended not only to the live persons but also to the passing spirits. Collectivity was also disclosed in the eating or table manners of Koreans. Koreans quite literally share food at every meal since the side dishes placed centrally on the table. The taste of Korean foods is completed inside the mouth by mixing foods with various combination, which let people create their own choice of taste. Therefore, the collectivity manners at the table appeared to be harmonized with individual freedom of creating his/her own taste of foods. The collectivity is still a very important concept in modem Korean dietary culture, as reflected by an increase of restaurants sewed shared dishes.

This study aims at providing useful information to establish subdivided marketing direction by deriving factors of significant extent and practicable extent of buffet users toward menu quality among super deluxe hotels in Gyeongju, and furthermore aims at presenting implications for efficient management result and sales increase of buffet in the future. The result of positive analysis is as follows. Firstly, in result of analyzing difference between importance and performance of hotel buffet in Gyungju area, importance is much higher than performance. Secondly, respondents consider that the most important menu of hotel buffet is main dish such as hot food and instant food rather than menu such as beverage, soup and salad. When it comes to attribute of menu quality, it appeared that respondents put highly significant extent on sanitariness of food, freshness of food, flavor of food, and seasonality and variety of menu. Thirdly, oriental instant food is included in the second quadrant of IPA regarding buffet menu which should be intensively managed. And three attributes such as temperature of food, time of changing food, and creativity of menu are included in the second quadrant of IPA graph by attribute of hotel buffet's menu quality. Lastly, in IPA graph by hotel, the following menus of each hotel need to be intensively managed: Oriental instant food of A hotel, Western cold food of B hotel, Oriental instant food, Western instant food, and Oriental dessert of C hotel, and Western porridge soup, Oriental instant food, and Western instant food of E hotel. The aforementioned menus should be improved.
