초록
카라기난 기반 복합필름은 세 가지 다른 아연 염(zinc acetate, zinc chloride 및 zinc nitrate) 원료를 사용하여 합성한 ZnONPs를 카라기난에 첨가하여 solvent casting 방법으로 제작되었다. SEM 결과에 따르면, 사용된 아연 염의 종류에 따라 ZnONPs의 크기와 모양에 차이가 나타났지만, 모든 ZnONPs가 카라기난 복합필름 내에서 균일하게 분산되어 있는 것을 확인할 수 있었다. 카라기난 기반 복합필름(Car-ZnONPs)의 두께는 아연 염의 종류와 관계없이 순수 카라기난 필름에 비해 증가하였다. 파단 연신율(EB)은 증가하였고, 인장강도(TS)는 유의적으로 감소하였으며, 탄성 계수(EM)는 유의적 차이를 나타내지 않았다. 이를 통해 복합필름의 기계적 특성인 TS와 EB는 첨가된 나노입자의 크기와 첨가량에 영향을 받는다는 것을 확인하였다. 또한, 모든 종류의 Car-ZnONPs 복합필름은 E. coli O157:H7 및 L. monocytogenes에 대해 강한 항균 활성을 나타냈으며, 특히 zinc chloride로 합성된 Car−ZnONPsZC 필름이 가장 우수한 항균 성능을 나타냈다. 이는 zinc chloride에서 합성된 나노입자가 다른 아연 염에 비해 더 많은 아연 이온을 방출하기 때문으로 판단된다. 아연 염의 종류가 ZnONPs의 항균 능력에 영향을 미치며, 이러한 영향은 염의 종류에 따라 변화하는 ZnONPs의 크기, 형태 및 아연 이온 방출 정도에서 기인한다. 평가된 복합필름 중 Car- ZnONPsZC가 가장 높은 자외선 차단 특성을 보였으며, 파단 연신율도 순수 카라기난 필름에 비해 유의미하게 증가하여, 포장된 식품의 안전성을 유지하고 유통기한을 연장하는 데 활성 포장 필름으로 사용될 수 있을 것으로 기대된다.
Abstract
In this study, zinc oxide nanoparticles (ZnONPs) were synthesized using three distinct zinc salts: zinc acetate, zinc chloride, and zinc nitrate. These ZnONPs were subsequently utilized in the fabrication of carrageenan-ZnONPs (Car-ZnONPs) composite films. The study assessed influence of the various ZnONPs on the morphological, water vapor barrier, color, optical, and antimicrobial properties of the Car-ZnONPs composite films. The surface morphology and UV-blocking attributes of the composite films were affected by the type of ZnONPs used, but their surface color, transparency, and chemical structure remained unaltered. The composite film's thickness and elongation at break (EB) significantly increased, while the tensile strength significantly decreased. In contrast, film’s elastic modulus (EM) and water vapor permeability coefficient (WVP) showed no significant difference. All the composite films with added ZnONPs demonstrated potent antibacterial activity against Escherichia coli O157:H7 and Listeria monocytogenes. Among the carrageenan-based composite films, Car-ZnONPsZC showed the highest antibacterial and UV-blocking properties, and its elongation at break was significantly higher than that of the pure carrageenan films. This suggests that ZnONPs composite films have the potential to be used as an active packaging film, preserve the safety of the packaged food and extend shelf life.
