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.

The functions of food packaging are not only prevention from physical damage and loss during carrying and transportation, but also extension of shelf-life by adding antimicrobial substrate in packaging materials. Consumption of active packaging is gradually increasing. With different dosage of potassium sorbate(P.S.), the food preservative agent, antimicrobial papers were made by internal and external application of starch. The antimicrobial action of the paper was analyzed by the halo test and the shake flask method. The mechanical properties and strength were also measured. Antimicrobial papers adding P.S. showed higher values in tensile index than adding starch. The antimicrobial paper using starch showed similar microbe decreasing rate as that using P.S. Though microbe decreasing rate was 21.9%, it showed possibility to make antimicrobial paper using food preservative.

The antimicrobial extracts of rheum palmatum and coptis chinensis root as well as grapefruit seed extract(GFSE) were applied to dipping treatment for keeping qualities of cucumbers, respectively, which were then packed in low density polyethylene(LDPE) films incorporated with 1 % antimicrobial extracts and stored $10^{\circ}C$. Dipping and packaging in the antimicrobial agents suppressed the growth of putrefactive microorgani는 and the decay ratio of cucumbers. In addition, the loss ratio of ascortic acid content and their weight was decreased during the sotrage of cucumbers. Consequently, the combined method of dippinf and packaging in antimicrobial agents turned out to be superior to dipping treatment or film-packaging in the view point of decay ratio and the keeping qualities of cucumbers.

식품의 저장성 및 안전성 향상을 목적으로 필름이나 용기형태의 항균 기능성 포장재를 개발하고자 하는 노력이 지속되고 있으며, 아울러 새로운 고분자 및 항균 소재 탐색에 대한 연구도 활발히 진행되고 있다. 이와 관련하여 기존의 합성 고분자뿐만 아니라 생고분자에 각종 항균제를 첨가 또는 혼입하여 제조한 식품 포장용 항균성 필름이 최근 들어 주목받고 있는데, 이러한 항균성 필름은 담체로 사용된 고분자는 물론 항균제의 종류, 이들의 상호작용에 따라 항균효과 및 지속기간, 필름의 물성 등이 현저하게 달라진다. 따라서 보다 효과적인 식품 포장용 항균 기능성 필름의 제조기술 개발을 위해 발표된 문헌 자료를 토대로 항균필름 제조에 사용된 고분자 소재와 항균제의 종류, 항균활성 평가방법, 제조방법에 따른 항균효과 및 필름의 물성 변화 등 항균필름의 종합적인 항균성 평가 결과를 중심으로 정리하였다.

Antimicrobial activities of the Acidic Liquid originated from Carbonized Rice Hull(ALCRH) and the paper treated with ALCRH were investigated to apply ALCRH to functional paper products as a natural antimicrobial agent. ALCRH showed antimicrobial activity for bacteria and yeast, with higher performance for bacteria than for yeast. Antimicrobial activity was not developed on paper coated with ALCRH by bar coater probably due to the evaporation of antimicrobial compounds of ALCRH from the paper surface with time. Saturation of paper with ALCRH was essential to develop antimicrobial activity on the paper. Dipping paper in ALCRH solution was recommended as one of the effective ways to make antimicrobial paper.

The management of oyster shell disposal is an ongoing challenge in the southern coast of Korea because of continuously dumping the oyster shell in environment. Oyster shell wastes could be a biocidal alternative after calcination using a heat treatment. Calcined oyster shell is normally obtained through thermally conversion of $CaCO_3$ (main component in oyster shell (96%)) into CaO. This study provides a brief overview of oyster shell disposal and its potential as an antimicrobial agent with a focus on calcination process, antimicrobial mechanisms, and packaging applications.

To develop a wrapping film, which suppresses the microbial decay through the storage and distribute of greenhouse fresh produce, the antimicrobial packaging films were made and applied to the preservation of grapes(Campbell early). For the purpose the films were made by adding 1% grapefruit seed extract(GFSE) to LDPE film(Control). Graps were separately wrapped with packaging films in the state of closely-adhered packaging as well as modified atmosphere packaging(MAP). The wrapped grapes were stored at 5$^{\circ}C$ for 65 days and then the colony count of contaminated microorganims, decay ration of grapes, the gas component within the packages and chemical qualities were investigated. The antimicrobial film packaging showed the efficient results to suppress microbial growth as compared with control. The total number of containated microorganisms were decreased gradually through all the storage period. In the closely-adhered packaging and MAP the decay ratios of grapes was 31% and 19%, indivisually. After the storage period of 65 days, the interior gas components of MAP were 4.5% of O2 and 17.6% of CO2, which were efficient for the storage of grapes. In addition, no negative effects in sweetness and acidities occurred.

풋고추를 수확하여 선도를 유지할 수 있도록 하기 위하여 천연항균소재를 이용한 항균용제와 항균포장필름에 대한 각각의 효과와 두 가지를 병행한 상승효과를 확인하기 위하여 풋고추를 항균용제에 침지 처리후 1$0^{\circ}C$에 저장하면서 품질변화를 측정하였다. 그 결과 항균용제와 항균포장필름에 대한 각각의 효과뿐만 아니라 두 가지를 병행하여 저장하는 경우 상승효과가 더욱 두드러지게 나타나는 것을 확인 할 수 있었다. 따라서 풋고추의 선도를 유지하는 데에 천연항균소재가 효과적으로 사용될 수 있는 것으로 나타났고, 이러한 용제가 실용가능성을 가질 수 있도록 다각도로 연구가 진행되어야 할 것으로 생각된다.

The botanical antimicrobial agent prepared from citrus fruits (BAAC) was prepared to provide inhibitory ability to packaging paper The BAAC diluted in 0.5% and 1% starch solution respectively was applied to packaging paper by the thin coating technique. The antimicrobial packaging paper displayed great inhibitory effect against the putrefying microbes including fungi, yeast and bacteria. Tn addition to antimicrobial activity of the packaging papers, their physical properties such as tensile strength, burst strength, tear strength and bending stiffness could be improved by simultaneous treatment with starch. Both the item packaging by tissue paper and the outer packaging by corrugated boxes, which were treated by the thin coating of BAAC and starch, exhibited great ability in preserving freshness of stored mandann oranges. The more treatment of BAAC was made in the packaging paper, the greater freshness-preserving ability was generated.
