Due to the rise of customer's alertness about fresh foods to health, in the past few years, the consumption of fresh food has increased sturdily. The use of gas scavengers is the most appropriate packaging technologies for fresh, fresh-cut produces and in ready to eat products. The gas absorber/scavenger has ability to protect or stabilize the wanted properties and shelf life of food. The success of gas absorbers in food depends on many parameters such as types of foods, storage temperature, relative humidity, initial gas concentration, and the characteristics of package materials. In this review article, we focus on the most recent research trends in gas scavenging systems used in food packaging, future trends. Intense research from industry and engineers remains important to the development of gas scavenging package that fulfill consumer requirements, enhance product quality, and offer environmentally friendly design and cost-effective application.

사회경제의 부단한 진보와 발전에 따라 상품 포장의 중요성은 나날이 현저해지고 있으며, 그것은 이미 사업자와 소비자 사이의 중요한 의사소통 형식이 되어, 사업자 간의 중요한 경쟁 수단이 되었다. 이 논문의 연구범위는: 우선 문헌 조사를 통해 포장설계의 기능과 소비자의 구매 태도를 분석하고 일반 초콜릿 포장과 여행기념품 초콜릿 포장을 대상으로 이름, 색상, 로고, 일러스트 등을 분석·연구했다. 연구방법은: 설문 조사를 통해 패키지 디자인에 대한 소비자의 구매 태도 및 개인의 가치 구현에 따라 소비자의 구매 여력과 패키지 디자인이 구매 조건에 미치는 영향과 연구를 심층적으로 살펴봤다. 본 연구의 결과, 첫째, 일반 초콜릿 포장과 여행기념품 초콜릿 포장부터 소비자 소비 현상까지 보면 일반 초콜릿이 더 선호된다. 둘째, 소비자가 제품을 구매할 때 초콜릿의 맛은 제품 패키지 디자인보다 중요한 속성이다. 셋째, 각 제품군에서 소비자들은 초콜릿 제품을 살 때 자신의 지향적인 가치를 중시한다. 넷째, 패키지 디자인과 맛이라는 두 가지 중요한 속성 아래 일반 초콜릿은 여행기념품 초콜릿보다 구매 의도가 높다.

The regulations for migration amounts in USA, EU and Korea are investigated to compare the actual overall and specific migration date from plastic food packaging materials. Among the packaging materials regulated in above countries, printing ink solvents on packaging materials is used very widely and sometimes cause off-flavor in the food by migration of residual solvents. Even though migration of the residual solvents dose not generally cause safety problems in the contained food, it certainly can generate off-flavor and finally deteriorate quality of the finished product. Therefore regulation and development of analytical method for amount of residual ink solvents are very important issue in food industry. The headspace analytical method and tenax method for residual ink solvent on food packaging materials were evaluated from the accuracy, precise, swiftness and convenience of viewpoint. Headspace analytical method was selected and recommended for using in food industry field.

This caused business drop longrightarrow Thermal simulation of some SIP product is essential in the beginning stage of SIP business planning (or design) stage. (i.e., DRAM embedded SIP) .When SIP is developed using discrete packages, the I/O driver Capa. of each device may be so high for SIP. Since I/O driver capa. was optimized to discrete package and set board environment, this resulted in severe noise problem in SIP. longrightarrow In this case, the electrical performance of product (including PKG) should have been considered (simulated) in the beginning stage of business planning (or design).

Objectives : The purpose of this report was to provide the information packaging of herbal medicines by analyzing papers. We investigated the packaging materials, packaging methods and expiration date of herbal medicines by analyzing papers of the Korea, Japan and China. Methods : We survey herbal medicine-related law and crude drug monograph of compendium in each three country, we purchased herbal medicine of the Korea, Japan and China in the market and verify the expressed-item in packing paper. In case of Japan, we examine packaging materials, packaging methods, and expiration date of herbal medicine in pharmaceutical company. Results : The pharmaceutical company in japan used the methods of nitrogen gas pouring, vacuum packing for the herbal medicine packaging. The expiration date of the herbal products in Japan is generally 3 to 5 year after packaging. And packaging materials were aluminium and polyethylene. In Korea, pharmaceutical company used airtight packing for the herbal medicine packaging and expiration date of the herbal product were generally 3 year after packaging. Packaging materials were polyethylene, nylon or polyethylene-nylon mixed materials. In China, pharmaceutical company also used airtight packing for the herbal medicine packaging, and the expiration date were generally 5 year after packaging. Packaging materials were polyethylene, wrapping paper-used parcel or tea leaves filter paper. Conclusion : This results can present the basic data for expiration date and preservation methods of the herbal roots in Korea.

The purpose of this study was to develop hand creams among the types of cosmetics based on domestic pumpkins grown in Yangju. Pumpkins are mostly used for cooking, but because they contain a large amount of vitamin A, they can also be used as raw materials for cosmetics to prevent skin aging. The final design was researched and developed through a graphic expression of pumpkin characteristics, a design process, and a survey on preference for differentiated packaging design. The survey targets women in their 20s and 30s who directly purchase cosmetics, and an analysis of consumers' preference for brand product decisions showed that simple and modern designs suitable for cosmetics images topped the list. In addition, it showed a positive image of cosmetics development using local agricultural products and high brand value. We present the possibility that domestic pumpkin raw materials can be applied to cosmetics and aim to develop excellent cosmetics brands through consumer preference surveys.

The purpose of this study was to assess the qualities of cook/chilled soy sauce-glazed soybean curd with various packaging conditions as a trial to develop health-oriented convenience foods. The effects of three packaging methods, linear low density-polyethylene (LLD-PE), top sealing, and modified atmosphere packaging(MAP) on the shelf-life of HACCP-based cook/chilled soy sauce-glazed soybean curd were evaluated during 20 days of chilled storage in terms of time-temperature, microbiological (total aerobic plate count, psychrotrophic plate count, coliform, and fecal coliform count), chemical(pH and peroxide value(POV)), and sensory evaluation. The results of microbiological and chemical analyses were within the limits of the microbial and chemical standards for all phases after cooking. No significant differences were detected in microbial counts of the samples for all three packaging methods. However, sensory evaluation indicated that the top sealing and MAP methods showed a longer shelf-life than LLD-PE packaging. Recommended shelf-life of the product was 12 days for LLD-PE packaging, and 16 days for both top sealing and MAP. In conclusion, MAP was considered as the most effective packaging method for assuring microbial and sensory quality of this cook/chilled product.

It is very difficult to export the fresh agricultural products to long distant countries such as America and EU without any damage. Fresh exporting products would be met very hazardous environments such as hot and cold weather, heavy trembles with rolling and pitching. Therefore, care should be taken on tight fastening the products inside the container and keeping the designated temperature and relative humidity. The physical strength of outer box should be applied differently because each agricultural product has its own character for packaging. There have been many agricultural products researches for export packaging to the U.S.A. so far. However they have never got desirable results which enough to apply it in real. The main purpose of this research is to develop optimum compressive strength of corrugated fiber board box which would be used to American export packaging of fresh agricultural products such as perilla leaves, green red pepper and spinach.
