  • 우유와 쏘세지 등 몇가지 동물성 식품의 보존에 미치는 오골계 난백 lysozyme의 효과를 검토하기 위하여 이들을 0.05% lysozyme 으로 처리한 후 $20^{\circ}C$, $30^{\circ}C$$37^{\circ}C$에 저장하면서 경시적으로 이들의 pH와 휘발성 염기질소 함량 및 생균수의 변화를 조사 하였다. 생우유를 lysozyme 으로 처리하여 $20^{\circ}C$에서 48시간 저장 하였을 때 휘발성 염기질소 함량이 63mg%로 제일 낮아 보존효과가 있었고 $30^{\circ}C$에서는 lysozyme 과 glycine의 혼용처리시 그 보존효과가 상승하였다. 또한 시판우유와 어묵에서도 lysozyme처리에 의한 보존효과가 있었으며 특히 솔빈산을 첨가하지 않은 쏘세지에 lysozyme 을 처리하여 $5^{\circ}C$에 저장 하였을 때 휘발성 염기질소 함량이 약 150 mg%로 비교적 낮았다.

  • This study aims to investigate the food preservation methods adopted by the Joseon Dynasty, which existed before the 17th century. A total of 232 food preservation methods were discovered in 25 books, and could be classified by their targeted food types: vegetables (84), sea foods (60), meats (41), fruits (37), and others (10). Depending on the preservation method applied, they are classified as food drying, soaking, mud cellar preservation, and other preservation. Food drying is further classified into 8 sub-types: drying, sun-drying, shadow-drying, wind-drying, dry heat, combined drying, smoking, and others. Soaking could be sub-divided into using salt, ash, dry sand, bran, fermented paste, wet distillers grains, oil, and others. Mud cellar preservation is sub-classified into installing shelf inside the mud cellar, making the mud cellar for food preservation, and making hole or underground tunnel for food preservation. Other food preservation methods include minimizing moisture loss by applying beeswax on a section of the vegetable stem, and cutting the vegetables or fruits with their branches and leaves for food preservation.

  • This study was conducted to approach the Korean new food words for the years 1994-2005 from the stance of food ethics. The new food words were categorized into food industry, foodstuffs, cooking, various foods, processed foods, distribution, and consumer health. The principles of food ethics applied to new food words include a respect for life, justice, environmental preservation, priority of safety, and dynamic equilibrium. Seventy percent of new food words were ethically neutral, while 30% had significant ethical meaning. There were more words with a negative ethical meaning than with a positive one. All of the principles, except respect for life, could be successfully applied to new food words. Dynamic equilibrium was the most appropriate principle for the new food words, followed by a priority for safety, justice, and environmental preservation. The results of this study implied that moderation and balance is required in our modern dietary life.

  • The purpose of this study was to reveal consumer attitudes about package colors of Korean traditional floods. The housewives preferred pale purple blue for soy sediment, red purple for soy soup, yellow for vinegar, red for power sediment. For the background color of each package, consumers tended to like similar color with color of the content, but did not show any bias for the lesser color of it. The statistically significant correlations between populational difference and package colors were not found.

  • The ultra-high pressure technology fur the preservation of foods is under intense research to evaluate its potential as an alternative or complementary process to traditional methods of food preservation. Traditional processing methods usually need a large amount of energy, may cause unwanted reactions in the food, leading to cooked flavor and loss of vitamins, etc. The application of ultra-high hydrostatic pressure for food processing consists of subjecting the food to pressures in the range of 100-1000 ㎫. The ultra-high pressure inactivates the microorganisms and some enzymes, promotes the germination of spores and extends the shelf-life of the foods. This new technology follows the “minimal processing” concept minimizing the quality degradation, saving the vitamins, essential nutrients and flavors as well as utilizing less energy. We joined the research team at our University involved in the mentioned technology using an ultra-high pressure equipment, recording of the near infrared spectra and signal response of a chemosensor array (electronic nose) of their meat (beef and pork), vegetable and fruit samples exposed to different pressure. The results of our investigations achieved by evaluating the measured data using PCA and PQS methods will be presented.

  • 지난 30년 동안 빠른 경제발전에 따른 가정 생활의 서구화의 경향으로 한국의 기업들은 제품을 디자인하는데 있어서 현재 소비자(생활자)들이 무엇을 요구하고 있는지 파악하는데 어려움을 주고 있다. 본 연구에서는 도구환경이라는 접근방법을 통하여 이 문제에 대한 디자인 해결방안을 찾고자 하였다. 도구환경이란 제품환경의 확대된 개념으로 깁슨(Gibson, J. J.)의 개념을 인용한다면 인간 행위 목적을 달성하기 위한 모든 수단으로서 물질적인 것과 공간적인 것을 포함하고 있다. 이 접근 방법의 논리와 구조에 관하여는 디자인 방법론과 역사학, 사회심리학, 인간행동과학 등의 제 분야에 기초를 두고 논하였다. 특히 우리 나라의 식품의 보존저장을 위한 도구환경에 대해 선사시대이후 현재에 이르기까지 변화를 고찰한 후 미래의 도구환경을 예측하였다.

  • The traditional ritual foods of Korea have developed with for many years, and differ by locality, family customs and religious characteristics. In an efforts to establish the database on that addresses the difficult issue of a classification system for traditional Korean foods, we have conducted a survey of a traditional Korean ritual foods. In the database, typical 10 rites are represented, covering birth to death, these are birth, the hundredth day after birth, the first birthday, the commemoration of finishing books(graduation), the coming of age ceremony, marriage, the birthday feast for an old man, the 60th wedding anniversary, the funeral, and the memorial service. For each rite, the appropriate traditional Korean foods are classified into 6 categories-main dishes, side dishes, tteok lyou, hangwa lyou, eumchung lyou and the others. Some of these have varied considerably with the passage of time, and some have since disappeared. This database provides a basis for generational transmission, preservation and development of traditional Korean ritual foods as one of the components traditional Korean culture.

  • Ginseng, one of the important economic crops, is processed into medicine, teas, beverages and even foods. Drying is the most important and burdensome work in the processing of ginseng, so development of ginseng dryer is needed for efficient drying and good quality of ginseng. Investigation of drying model is essential for development of ginseng dryer. Drying models for peeled ginseng were investigated to determine dominant drying factors and fitted with five selected drying models and an empirical model. Thompson and the empirical model showed best fit with the experimental data. Pother experiment is necessary to prove the superiority of the empirical models.

  • Purpose: Cold storage is the most popular method used to preserve highly perishable foods such as beef and fish. However, at refrigeration temperatures, the shelf life of these foods is limited, and spoilage leads to massive food waste. Moreover, freezing significantly affects the food's properties. Ice crystallization and growth during freezing can cause irreversible textural damage to foods through volumetric expansion, moisture migration induced by osmotic pressure gradients, and concentration of solutes,which can lead to protein denaturation. Methods: Although freezing can preserve perishable foods for months, these disruptive changes decrease the consumer's perception of the food's quality. Therefore, the development and testing of new and improved cold storage technologies is a worthwhile pursuit. Results: The process of maintaining a food product in an unfrozen state below its equilibrium freezing temperature is known as supercooling. As supercooling has been shown to offer a considerable improvement over refrigeration for extending a perishable product's shelf life, implementation of supercooling in households and commercial refrigeration units would help diminish food waste. Conclusions: A commercially viable supercooling unit for all perishable food items is currently being developed and fabricated. Buildup of this technology will provide a meaningful improvement in the cold storage of perishable foods, and will have a significant impact on the refrigeration market as a whole.
