  • Effects of vacuum packaging and modified atmosphere packaging (MAP) on shelf life of selenium-supplemented chicken meat during refrigerated storage were examined. Body weight and feed efficiency were unaffected by dietary selenium level. Dietary treatments and packaging methods had no significant effects on level of microbial growth, lightness, and metmyoglobin content. MAP decreased purge loss (10.9-34.5%) and lipid oxidation (15.2-15.9%) more efficiently than vacuum packaging. Broiler chicks supplemented with ${\alpha}$-tocopherol or ${\alpha}$-tocopherol + selenium had similar TBA values. Dietary supplementation of 4 and 8 ppm selenium reduced lipid oxidation, and this effect was less significant in MAP breast meat.

  • The microbial growth of fresh, vacuum packaged, cook-in-bag uncured beef patties was determined in two film structures, a commercial (PE/EVOH), and super barrier ($SiO_2$ coated polyester) material. Packaged samples were cooked to internal temperature of 71 and $82^{\circ}C$ for 30 minutes, and stored in temperature abused ($23{\pm}2^{\circ}C$) and refrigerated storage ($4-6^{\circ}C$). Barrier properties had a significant effect (p<0.001) on aerobic and mesophilic growth in the abused condition. Cooking temperatures had a statistically significant effect (p<0.05) on aerobic growth in the refrigerated condition. The growth of anaerobes and psychrophiles were not significantly effected by either variables. Storage times had the most significant effect (p<0.001) for all groups of microorganisms. The physical properties of the commercial film (strength, thickness, and shrinkage) were changed after exposure to thermal treatment, while the super barrier package had actually no change.

  • 닭고기를 $4^{\circ}C$에서 냉장 보관할 경우 포장방법이 닭고기의 저장성에 미치는 영향을 검토하였다. 닭고기의 저장성은 저장 중 닭고기의 표면 미생물 및 이화학적 품질을 조사함으로서 결정하였으며 사용된 닭고기는 포장하기 전에 7.5% potassium sorbate용액에 미리 침지한 후 일반포장, 진공포장, 혼합가스포장 등의 포장을 하였다. 이렇게 조사된 포장 닭고기의 저장성은 일반포장육의 경우에는 $19\pm3$일간, 진공포장육의 경우에는 $30\pm5$일간, 10% $CO_2$가스와 90% $N_2$가스 조성의 혼합가스 포장육의 경우에는 $26\pm4$일간, 20% $CO_2$ 가스와 80% $N_2$가스 조성의 혼합가스 포장육의 경우에는 $30\pm5$일간으로 나타나 진공포장육과 20% $CO_2$가스와 80% $N_2$ 가스 조성의 혼합가스 포장육의 경우가 가장 높은 저장성을 나타내었다. 그러나 진공포장의 경우에는 진공시의 압력차로 육즙이 침출 되어 포장지 내부에 고여 있는 등 혼합가스 포장에 비해 관능적으로 나빠 20% $CO_2$가스와 80% $N_2$ 가스 조성의 혼합가스 포장이 기호성과 저장성을 고려할 때 가장 바람직한 포장방법으로 평가되었다.

  • This study aimed to focus on the optimization of the external dimension sizes in the corrugated fiberboard cartons (CFCs) for exporting agricultural products. The commercial CFCs of current fresh produces such as paprika, Asian pear, melon, sweet potato, and oriental melon for export were used for this study. The guidelines of the minimum internal dimensions of the refrigerated reefer container, the dimensions of pallets, and the maximum load height of a stack were referred to KS T ISO 668, KS T 1372, and the Container Handbook by the German Insurance Association, respectively. These principles were selected as a ground rule for the external dimensions of CFCs. Package layout design programs of ArtiosCAD and Cape Pack software were used to confirm the box stacking patterns and revise the external dimension of CFCs. The final external dimensions of each CFC were revised from 5 to 30 mm compared to its original dimensions. The maximum load of each stacking box per pallet has been increased from 0.0 to 12.5% compared to its original load.

  • 블루베리 및 딸기의 품질유지를 위한 MAP의 활용 가능성을 확인하고자 비가열 병합 처리 세척과정을 거친 '엘리오트' 블루베리와 '설향' 딸기 시료를 기체투과도가 다른 polyolefin film(6,000 mL $O_2/m^2{\cdot}24hr{\cdot}atm$ at $24^{\circ}C$)과 PA/PA/PE film(60 mL $O_2/m^2{\cdot}24hr{\cdot}atm$ at $24^{\circ}C$)에 각각 포장한 후 $4^{\circ}C$에 저장하면서 품질 변화를 측정하였다. 수확 후 블루베리와 딸기에 병합 세척처리를 한 결과, 총 호기성균은 각각 2.50, 1.97 log CFU/g, 효모 및 곰팡이에서는 각각 1.95, 2.18 log CFU/g의 감균 효과를 얻어 우수한 살균 효과를 나타내었다. 또한 PA/PA/PE film 포장에 의한 낮은 기체투과도로 인한 높은 이산화탄소 농도 환경에서 미생물의 생육이 저장 중 억제되는 것을 확인하였고, 중량 감소율에 있어서도 높은 기체투과도를 갖는 polyolefin film으로 포장한 처리구보다 낮은 감소율을 보여, 소포장된 블루베리와 딸기의 경우 기체투과도가 낮은 포장재를 이용하는 것이 효율적인 것으로 나타났다. 따라서 본 연구 결과, 수확 후 블루베리 및 딸기의 적절한 기체 조성을 위한 포장재의 선택은 품질 유지 및 유통기한 증대에 도움을 줄 것으로 판단된다.

  • The objective of this study was to investigate comparison of physicochemical, microbiological, and sensory characteristics of Hanwoo eye of round by various packaging methods [wrapped packaging (WP), modified atmosphere packaging (MAP), vacuum packaging (VP) with three different vacuum films, and vacuum skin packaging (VSP)] at a small scale. Packaged Hanwoo beef samples were stored in refrigerated conditions ($4{\pm}1^{\circ}C$) for 28 days. Packaged beef was sampled on days 0, 7, 14, 21, and 28. Physicochemical [pH, surface color, thiobarbituric acid reactive substances (TBARS), and volatile basic nitrogen (VBN) values], microbiological, and sensory analysis of packaged beef samples were performed. VP and VSP samples showed low TBARS and VBN values, and pH and surface color did not change substantially during the 28-day period. For VSP, total viable bacteria, psychrotrophic bacteria, lactic acid bacteria, and coliform counts were lower than those for other packaging systems. Salmonella spp. and Escherichia coli O157:H7 were not detected in any packaged beef samples. A sensory analysis showed that the scores for appearance, flavor, color, and overall acceptability did not change significantly until day 7. In total, VSP was effective with respect to significantly higher $a^*$ values, physicochemical stability, and microbial safety in Hanwoo packaging (p<0.05).

  • 가열조리 냉동된 닭 가슴살 patty와 nugget을 계육가공공장으로부터 얻어서 진공과 비진공으로 포장한 뒤 $2-4^{\circ}C$로 냉장저장하였다. 이 제품의 품질을 28일간 4일 간격으로 측정하였다. 진공포장방법으로는 냉장저장된 제품의 미생물 총균수는 줄이지 못하였으며 비진공 포장된 제품의 총곰팡이 수는 실험기간 동안 증가한 반면 진공포장된 제품은 log값 3.5부터 정체기에 들어갔다. 진공포장은 TBA값의 증가를 막지 못했으며 유지방산 값은 실험기간 동안 낮은 일정한 값을 보였다. 진공 및 비진공포장 방법 그 어느 경우에도 제품색깔은 현저하게 변했다.

  • 진공포장, 'rub', 저장온도와 첨가물에 따른 marinated 닭 drummettes의 품질변화를 조사했다. Drummettes의 초기 미생물 수에 따라 제품 품질수명은 영향을 받았다. 내부온도가 $93.3^{\circ}C$로 조리된 제품은 $82.2^{\circ}C$로 조리된 제품보다 품질수명이 길었다. 하지만 marinated 과정중 'rub'가 이용된 경우 위와 같은 장점은 나타나지 않았다. 냉장저장($3{\pm}1^{\circ}C$$7{\pm}1^{\circ}C$)중 진공과 비진공 포장된 제품의 미생물 총균수는 현저한 차이가 없었다(P>0.05). Marinated 용액에 솔빈산(0.5%)이나 안식향산 나트륨(0.5%)을 첨가하여 제품 품질수명은 연장 되었으며 아질산 나트륨 50ppm을 첨가하여 좀더 연장 되었다. 진공포장과 marinated 용액에 솔빈산이나 안식향산 나트륨을 첨가하여 제품의 TBA값 증가를 둔화시켰다.

  • The effect of modified atmosphere packaging (MAP; 30% $CO_2$+70% $N_2$ or 100% $N_2$) and an additive mixture (500 ppm rosemary extract, 3,000 ppm sodium acetate and 1,500 ppm calcium lactate) on the quality of pre-cooked hamburger patties during storage at $5^{\circ}C$ for 14 d was evaluated. The addition of the additive mixture reduced aerobic and anaerobic bacteria counts in both 30% $CO_2$-MAP (30% $CO_2$+70% $N_2$) and 100% $N_2$-MAP (p<0.05). The 30% $CO_2$-MAP was more effective to suppress the microbial growth than 100% $N_2$-MAP, moreover the 30% $CO_2$-MAP combined with additive mixture resulted in the lowest bacterial counts. The hamburger patties with additive mixture showed lower CIE $L^*$ and CIE $a^*$, and higher CIE $b^*$ than those with no additive mixture. The 30% $CO_2$-MAP tended to decrease the TBARS during storage regardless of the addition of additives. The use of 30% $CO_2$-MAP in combination with additives mixture was effective for maintaining the quality and extending the shelf-life of pre-cooked hamburger patties.
