Agar-based composite films were prepared with variety of food processing and agricultural processing waste materials in order to screen natural lingo-cellulosic resources for the value-added utilization of the under-utilized materials. The effect of these waste materials (10 wt% based on agar) on mechanical properties, moisture content (MC), water vapor permeability (WVP), water absorption behavior of biocomposite films were investigated. Biocomposite films prepared with various fibers resulted in significant increase or decrease in color and percent transmittance. The MC, WVP, and surface hydrophobicity of biocomposite films increased significantly by incorporation of fibers, while the water uptake ratio and solubility of the film decreased. SEM images of biocomposite film showed better adhesion between the fiber and agar polymer. Among the tested cellulosic waste materials, rice wine waste, onion and garlic fibers were promising for the value-added utilization as a reinforcing material for the preparation of biocomposite food packaging films.

플라스틱 포장재의 주요 기능은 식품을 수송, 보관과정에서 안전하게 보존하는 것이다. 식품과 플라스틱 포장재간의 반응은 식품의 품질과 안전성 문제에 있어서 상당한 이슈가 되고 있는데 이는 주로 플라스틱에 남아있는 잔류용제, 단량체, 첨가물 등이 식품으로 전이되는 문제들이다. 플라스틱 포장재에 항산화제를 첨가하는 것은 필름의 열화는 물론 포장된 식품, 특히 유지가 많은 제품의 산화를 막을 수 있다. 현재 BHT와 같은 항산화제를 플라스틱 포장재에 적용하는 것이 상업화되어 제품의 유통기간을 연장시키는 방법으로 사용되고 있다. Alpha tocopherol은 가장 중요한 자유기 제거제의 하나로 생물 시스템에는 잘 알려져 있는데 이것을 포장재에 사용함으로써 생산자와 소비자 모두 매우 긍정적인 반응을 보이고 있다. Alpha tocopherol은 폴리올레핀계 레진에 적용되어 BHT를 대체하고 있다. 이 연구는 포장재와 제품간의 증발-흡착 메카니즘을 이용한 항산화제의 효과와 그 적용, 그리고 이러한 메카니즘을 예측할 수 있는 분석기법을 설명하였다.

식품포장의 발전은 식품 제조 및 식품 공급을 안전하게 유지하는 데 매우 중요한 역할을 한다. 식품포장은 식품의 보관, 취급, 운송 및 보존을 용이하게 하며 음식물 쓰레기를 최소화하는데도 기여하고 있다. 반면에 식품포장재는 생산량이 많고 사용 시간이 짧고 폐기물 관리 및 쓰레기와 관련된 환경문제 발생을 가속시키고 있으므로, 포장 기술은 식품 보호와 에너지 및 재료 비용, 환경사회적 의식 고양, 그리고 오염물질 및 도시고형폐기물 처리에 대한 엄격한 규제 등의 문제와 균형을 이루며 발전되어야 한다. 자원의 절약과 재활용을 통해 지속가능성을 추구하며 폐기물 생성 및 탄소배출을 줄이는 순환경제(Circular Economy)가 이미 도입되었다. 자원고갈과 환경오염을 최대한으로 줄이는 친환경 경제시스템을 활성화하여 감량, 재사용, 재활용, 재설계로 순환경제의 목표를 실천하면 식품포장이 환경에 미치는 영향도 줄일 수 있을 것이다. 이 고찰에서는, 재활용이 현재 포장 폐기물을 관리하는 중요한 수단으로 여겨지기 때문에 재활용 식품포장의 안전성 측면에 중점을 두어 설명하였다. 재활용은 잠재적으로 위험한 화학물질이 포장재에서 또는 식품으로 이행된 후의 그 수준을 증가시킬 수 있으므로 재활용 포장재의 안전성을 평가하는 것은 매우 중요하다. 플라스틱, 종이 및 판지, 알루미늄, 강철 및 다중재료 다층 포장 등 다양한 식품포장 재료가 일반적으로 사용되나 여기서는 가장 사용 비중이 크고 사용 후 문제가 심각하게 증가되고 있는 플라스틱 식품포장재의 재활용 안전성에 대해서만 고찰하였다.

The term 'antimicrobial' packaging encompasses any packaging technique(s) used to control microbial growth in the food product. These include packaging materials and edible films and coatings that contain antimicrobial agents, and also techniques that modify the atmosphere within the package. In recent years, antimicrobial packaging has attracted much attention from the food industry because of the increase in consumer demand for minimally processed, preservative-free products. Reflecting this demand, the preservative agents must be applied to packaging in such a way that only low levels of preservatives come into contact with the food. The film or coating technique is considered to be more effective, although more complicated to apply. New antimicrobial packaging materials are being developed continually. Many of them exploit natural agents, to control common food-borne microorganisms. Current trends suggest that in due course, packaging will generally incorporate antimicrobial agents and the sealing systems will continue to improve. The focus of packaging in the past has been on the appearance, size and integrity of the package. A greater emphasis on safety features associated with the addition of antimicrobial agents is perhaps the next area for development in packaging technology.

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.

Corrugated board provides packaging for most diverse industries with a share of over 50%, due to the numerous advantages they offer a good protection of the products. In other hand corrugated board fails in environmental conditions, indicating that relative humidity or temperature is higher. These effects directly damage the product packaged. To overcome on this problem recently corrugated boards produced with functional material, "functional corrugated boards," have become more available in the current market. A number of commercialized forms of functional material are coated or composited products with inorganic materials, for example "Nano clay" as representative. However, although the use of functional materials is increasing in corrugated boards, the several concerns such as over cost, environmental friendly materials, recycling, and toxicity affect consumer perceptions and acceptance. In the past, number of researcher focused on process of box compression and the utility of box compression testing etc., best of our knowledge there is no review paper which focus on the functional corrugated boards used in food packaging applications. This paper aims to review the availability of functional corrugated boards in the current market, past research studies on functional material and present the current status of functional corrugated boards in leading countries.

The effects of packaging materials, Ny/PE, PET/PE/Al, PET/PE/LDPE/CPP, and PET/Al/Ny/CPP, and packaging methods, atmospheric and vacuum packaging on physicochemical properties of onion Kimchi and rosemary-onion Kimchi were investigated. The maximun swelling days of packaging materials were increased more in rosemary-onion Kimchi than in onion kimchi, and they were in the order of PET/Al/Ny/CPP, PET/PE/Al, PET/PE/LDPE/CPP, and Ny/PE. The pH and reducing sugar contents of onion Kimchi and rosemary-onion Kimchi were decreased during storage. and those of lion Kimchi and rosemary-onion Kimchi packaged in PET/Al/Ny/CPP were higher than those in different packaging materials. Titratible acidity and vitamin C content of rosemary-onion Kimchi were lower than those of onion Kimchi, but there were no differences in the L and b values between two groups.
