Vacuum cooling were carried out for freshness keeping of shiitake mushroom. Shiitake mushroom was cooled within 30 minutes from $20.5^{\circ}C$ to $0.5^{\circ}C$ by vacuum cooling, and then temperature drop of $6.6^{\circ}C$ per weight loss of 1% was taken place during precooling. Weight loss, surface discoloration and softening were reduced by precooling. Judging from organoleptic properties such as cap opening, discoloration, texture and off-flavor, shelf-life of precooled mushroom was lengthed by 20% than that of non-treated mushrooms. Considering effect of packing material on freshness of shiitake mushroom after precooling, weight retention, hardness and organoleptic properties of mushroom packed with PVC wrap were superior to those packed in carton box.

Supercritical carbon dioxide ($SCO_2$) extraction was investigated as a method for protein-sourcing material from squid viscera. To find the optimum conditions, the extraction of squid viscera using $SCO_2$ was performed under the conditions of temperature range from 35 to $45^{\circ}C$ and constant pressure 25 MPa using Hewlett-Packard 7680T. Also from result of SDS-PAGE, the protein denaturation was minimized when using $SCO_2$ extraction. And the major amino acids in the squid viscera were glutamic acid, aspartic acid, lysine, leucine, arginine, alanine, glycine, isoleucine, and valine. The main fatty acids from squid viscera were myristic acid, palmitic acid, stearic acid, heneicosanoic acid, palmitoleic acid, elaidic acid, oleic acid, eicosenoic acid, EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid).

This study was designed to establish Korean food culture by considering traditional fruit preserve. A historical approach of traditional fruit preserve were reviewed by the cooking book published from 1670 to 1988 in Korea. The results obtained from this study are as follows. Cooking method of fruit preserve was firstly published to Omshikdimibang in 1670 and published moderate cooking book in 1988 but fruit preserve has not been cooked yet. Cooking method of fruit juice and starch had been started in Samkuk dynasty and was completed in Lee Dynasty. Compared with the western fruit jelly, mung bean starch was used as a gel forming material in Korean traditional fruit preserve while gelatin was used as a gelling agent in western fruit jelly. Western fruit jelly was succeed in innovation, but traditional fruit jelly was failed to innovation.

This is a summary of a comparative study of the national policies to foster the agri-food industry implemented by the leading countries of the industry before and after the COVID-19-induced global economic crisis. By comparing the policies of each country, we discovered that key leading countries of the agri-food industry had given up or suspended one-on-one, face-to-face support programs that they had maintained for years, and have started providing financial assistance to companies or self-employed people in relative industries. Korea should implement such decisive policies for the Korean agri-food industry to tackle this unprecedented economic shrink and maintain the competitiveness of the industry. Considering the scale and speed of the spreading of the pandemic, the new policies should be implemented swiftly and boldly. This study can be used as a base material for developing new policies to minimize damage to the agri-food industry and national economy caused by COVID-19.

The objective of this study is to show how much it could impact improvement expectation by adopting E-procurement system. Based on literature review, the following hypotheses were proposed: H1; The level of perception for adopting E-procurement system will be different by hotel's grade, the number of hotel rooms, types of Management, the number of employees. H2; Perception for adopting E-procurement system will influence improvement expectation of food material purchasing, beverage material purchasing, Room guest supplies & cleaning supplies, general material purchasing. H2-1, H2-2, H2-3, H2-4; Perception for adopting E-procurement system will differently influence improvement expectation of food material purchasing, beverage material purchasing, Room guest supplies & cleaning supplies, general material purchasing by job level and job performance. As a result, perception for adopting E-procurement system is in proportion to improvement expectation of purchasing and hypotheses related with job level and job performance which are moderating variables were accepted partially.

Food is one of the essential elements of the tourist experiences. The study aims to segment food tourists for benefit sought. This study attempted to segment tourists who had experienced local food at tourist destinations by their benefit sought to meet local food. A self-administered survey was obtained from 498 visitors in the study areas. Results from the factor analysis show that the most explained variances of benefit sought were food taste (17.2%) and refresh (12.9%). Five distinct segments were identified based on the benefits; family seeker (17.6%), passive seeker (15.1%), want-it-all seeker (23.1%), raw material seeker (31.8%), gastronomic seeker (12.4%). In addition, a significant difference in the characteristics of tourists who had tasted local food at tourist destinations was observed in terms of occupation, income, education, expenditure for food, and tour distance. Implications are discussed relative to marketing strategies.

The issue of food security will become one of the most widely concerned area of public policy in North East Asia coming 21st century. Although those countries such as China, Japan, South and North Koreas and Mongolia places emphasis on the need to have stable and reliable capacity for food production, it will be highly possible for these regions to experience the shortage of food supply due to growing population, expanding urbanization and rapid industrialization within next decade. Since world food markets are characterized as unstable structure and dominated by large multinational firms, their reliances on importing staple food may create the aggravation of food shortage problem in emergency situations. One possible proposal for solving food security in north-east region might be movements toward multilateral food supply assurance agreements as a component of trade negotiations among these countries. As measures for cooperation for securing food supply in these regions, following principles would be suggested; 1) encouraging agricultural cooperation based on private business, 2) exchange of technical and human resources rather than material support, 3) developing mutual concern and benefits, 4) managing joint buffer stock for staple food.

School food service must be operated as the part of the education. But it seems that it is not to be considered as an important educational field from the perspective of educational administration. This study was conducted to suggest the effective plan to improve the quality of the school food service system. Questionaries were distributed to 51 administrators and 85 dieticians of primary schools in Incheon area from Aug 7th to Aug 31st 2000. Drawbacks of school food service system cited from the survey results were insufficient support from the authorities both in policy and in budget and shortage of specialists for food service administration. Both dieticians and administrators acknowledged that available facilities required for the school food service were insufficient. 85.9% of dietition and 51.0% of administrators thought dietition of school food service to be suitable for nutrition education. For effective nutrition education, they suggest to have teachers taking in charge of nutrition education, to have teaching system related with school food service and to develope visual auditorial teaching material. For improvement of the quality of school food service, it is necessary to acquire sufficient budget and political support from the government and to have specialists for food service administration. And regulations promoting dieticians to be teachers of nutrition education is required to be introduced in the near future.
