This study was conducted to evaluating the antioxidative activities of waffle by natural antioxidants combination (tocopherol, rosemary extract and tea polyphenol) and packaging. Waffle stored at $25^{\circ}C$ and 35$^{\circ}C$ for 70 days were evaluated for acid value, peroxide value and Q$_{10}$ value. Tocopherol, either alone or with rosemary and tea polyphenol, was highly effective in inhibiting lipid oxidation of waffle at $25^{\circ}C$ and 35$^{\circ}C$. Especially among them, rosemary extract exhibited the best synergistic effect, as determined by peroxide value measurement. Waffle was then packaged under the following packing materials (OPP/DL/VMCPP, PET/DL/VMCCP). As the temperature condition, the modified atmosphere decrease in waffle package and increase peroxide value. This result indicated that the PET package was more effective in reducing oxidation than the OPP package.

Quality change of Kimchi packaged with Ny/PE, Ny/CPP (PPtray+Ny/CPP cover), Cryovac BK-1, BK-4, and PET/Al/PE film was observed during storage at $5^{\circ}C$ (97%RH) and $20^{\circ}C$ (76%RH). To evaluate quality change of Kimchi, gas composition of package, pH, acidity, color, growth of lactic acid bacteria, and sensory score were measured periodically. Regarding to gas composition of package, Kimchi packaged with PET/Al/PE showed higher oxygen concentration at the beginning of storage than the others; carbon dioxide concentration was almost 100% at the end of storage. Carbon dioxide concentration of Kimchi packaged with Cryovac BK-1 and BK-4 which has higher gas permeability than the others, was increased to a maximum and then decreased due to permeation of gas during storage; oxygen concentration was increased. Unlike Kimchi packaged with Ny/PE, Ny/CPP, and PET/Al/PE, package swelling was not observed in Kimchi packaged with Cryovac BK-1 and BK-4 during storage. Although pH change was not significant depending on the packaging material, Kimchi packaged with Cryovac BK-1 and BK-4 showed lower pH value and higher acidity than those of the others. Color change of Kimchi was different depending on the packaging material during storage. Difference of the growth of lactic acid bacteria and sensory evaluation were not significant among Kimchi packaged with different packaging material during storage at either temperature. In conclusion, the effect of packaging materials on the quality change of Kimchi was not significant; however, to prevent from swelling of packaged Kimchi which is one of the most serious problem during storage and distribution, might be avoided by using relatively high $CO_2$ permeable film than high gas barrier film.

This paper concerns the freshness of rice depending on packing materials using MANOVA. Freshness of rice is measured in terms of moisture content and rice flavor. Ordinary paper and charcoal-coated paper are compared as packing materials. Storing places are considered as a block. The bivariate observations of moisture content and the rice flavor are compared using MANOVA for a completely randomized block design. It is observed that there is a significant difference between ordinary paper and charcoal-coated paper. Therefore we apply ANOVA for moisture content and rice flavor, respectively. Significant differences are observed for the moisture content but not for the rice flavor.

환경부(장관 윤성규)가 지난해 11월 23일에 시행된 '자원의 절약과 재활용촉진에 관한 법률'에 따라 '포장재 재질 구조개선 등에 관한 기준'과 '재활용 의무이행 인증절차 및 인증표시 등에 관한 고시'를 제정하여 7월 30일부터 시행한다고 밝혔다. 환경부는 이번 고시 제정을 계기로 설계 생산단계부터 재활용 용이성을 고려함으로써 재활용비용을 절감하고 고부가가치 재활용제품을 생산하는 한편, 우수기업에 대한 혜택을 제공하여 생산-재활용이 촉진되는 선순환구조를 기대하고 있다. 본 고에서는 관련 법안의 내용에 대해 살펴보도록 한다.
