In order to study the natural preservation of food, sixteen kinds of medicinal plants were extracted by 80% methanol and then antimicrobial activity of the extracts was investigated against various kinds of microorganisms. The extracts of medicinal plants showed good effects of antimicrobial activity against bacteria except Bacillus cereus, Escherichia coli O-157. Especially, the extracts of Artemisia annua, Aster scaber, Solidago virganrea shower good inhibitory effects on the growth of bacteria to the cooling preservation foods, and Artemisia annua was decreased of the TMA(Trimethylamine) test. the result thus indicate that Artemisia annua, Aster scaber, Solidago fischeri extract inhibitory effects on cooling preservation foods, so that it may be potential as a natural preservatives.

Traditional cuisine reflects cooking traditions shaped by political, economic, social, cultural, and environmental conditions characterized by authenticity and uniqueness. Traditional food is not only a part of our cultural heritage but also a knowledge resource. Application of food science and technology in Korean traditional foods was reviewed from six points of view, including food preservation, fermentation, changes in food materials, utilization of food functionality, and packaging and development of cooking appliances. Books from disparate times were chosen in order to cover a wide range of materials from the past to the present. Food preservation and fermentation techniques were applied to various food materials. Combination of science and skills contributes to the accessibility of diverse food materials and better quality foods. Koreans use assorted and resilient plants, which have an abundance of functional substances such as food materials. Among cooking appliances, microwave oven and refrigerator are the most innovative products with huge influences on food eating patterns as well as lifestyle. Packaging effectively reduces post-harvest preservation losses, and better packaging has technical improvements for storage and distribution. Kimchi was chosen as an example in order to study technology from the past to the present. Availability of Kimchi cabbage, enrichment of functional ingredients, identification of useful microbial species, standardization of recipe for commercialization, prevention of texture softening, introduction of salted Kimchi cabbage and Kimchi refrigerators, and packaging were reviewed. The future of traditional foods in the market will be competitive. First, traditional foods market should be maintained to protect the diversity of food materials. Secondly, tailored foods for individuals should be considered using foods with functional properties. Information on health benefits would provide insights into health and traditional food products. Third, speedy transfer of new technology to the traditional food industry is needed to ensure food quality production and new opportunities in the market. Fourth, safety of traditional foods should be ensured without sacrificing the essential characteristics of culturally important foods. Improvement of logistics, distribution, and facility should be carried out. As demand for convenience foods increases, traditional foods should be developed into products.

The effects of microwave treatment on the perservation of foods, such as a seaweed soup and sea stoned radish shreds, were studied. Microwave treatment of microbial cell suspensions revealed that viable cells decreased dramatically when heated to 6$0^{\circ}C$. However, it was unlikely that microwave treatment to 60 is enough to decrease the viable cell counts efficiently in a seaweed soup and radish shreds. It was thought that microwave heating to at least 7$0^{\circ}C$ as a final temperature was an important factor to reduce microbial cell counts in foods. When foods were heated to 7$0^{\circ}C$ with a repetitive 15 sec "on" followed by 30 sec "off", no big differences were observed in viable counts during storage at 2$0^{\circ}C$ for 3 days, as compared to those treated with a full power. The microwave treatment with three stages was designed to solve problems associated with variations depending on food volumes and difficulties of heat diffusion in a solid food to be irradiated with a microwave oven. The three stage method was found to have a similar efficiency in the reduction of viable cell counts in foods to microwave treatment at a full power and to conventional methods, such as water bath heating or boiling for 3 min with a gas range.in with a gas range.

포장식품의 유통기한 표시기법에 대한 대구ㆍ경북지역 소비자 222명의 심리를 설문조사 방법을 통하여 분석한 결과 소비자들은 포장식품의 유통기한 표시가 매우 중요한 정보라고 생각하고 있었으나 불분명한 유통기한 표시에 매우 혼란스러워 하고 있었다. 유통기한의 중요성에 대한 인식은 식품의 부패성향이 클수록 높았다. 유통기한이 지난 제품에 대해 대부분의 소비자들이 식용을 꺼리고 있었으며 역시 부패성향이 클수록 높았다. 소비자들이 가장 선호하는 표시기법은 선도유지기한 또는 유효기한이었고 포장일자가 가장 낮았다. 인구통계학적 상관관계를 조사한 결과 나이가 어리고 여성의 경우 유통기한이 제품선택에 있어서 보다 중요한 요소로 작용하였다.

This study intended to find out what the male and female university students in Kyung-book area think about Korean traditional foods, how much they use them, and how their life styles affect their estimates on traditional foods. They evaluated the aspects of traditional foods highly in the order of nutrition(6.07), taste(5.96), appearance(5.40), color(5.33), preservation after cooking(4.82), cost(4.63), and cooking method(4.43). Female students had higher estimates on traditional foods than male students. There was no significant difference in the evaluation between the students raised in rural and urban areas if they had the same educational level. Regardless of gender, Kimchi was most preferred followed by boiled rice, pot stew, grilled fish, and beef out of 25 traditional foods. In the correlation among the evaluation factors and uses of traditional foods, those with high evaluation on traditional foods(r=0.282, p<0.01) and the families with higher income(r=0.316, p<0.01) made more use of traditional foods. For the life style, leisure-valuing type was the greatest part(39.4%) in male students and altruistic type(31.9%) in female students. The altruistic type comprised of the greatest part(34.8%) among the students raised in urban areas and the leisure-valuing type(40.0%) among those raised in rural areas. The altruistic type students put high values on taste, nutrition, appearance, color, and preservation after cooking of the traditional foods. The egocentric type gave high values on cost and cooking method. However, there were no significant differences among the types in every item. The altruistic type put the highest and the leisure-valuing type put the lowest value on traditional foods, respectively, however, it was not significantly different. The individuality-centered type made the most use of traditional foods, whereas the leisure-valuing type made the least(p<0.05).
