Preparation of Polyvinyl Alcohol/Silver Nanoparticles Film and Its Application in Fresh Noodles Leaf Preservation
摘要
Abstract
In this study,polyvinyl alcohol(PVA)and distilled water were used as raw materials,glycerol was used as plasticizer.The PVA/AgNPs composite films with different proportions of silver nanoparticles(0%,1%,2%and 4%)were prepared by solution casting method.The mechanical properties,barrier property and antibacterial property of the films were characterized.The suitable film was applied to the fresh-keeping of fresh noodles leaf,and its effect on the quality of fresh noodles leaf was studied.The results showed that 4%PVA/AgNPs films had better mechanical properties,barrier properties and antibacterial properties.The diameter of the inhibitory circle against Staphylococcus aureus reached 11.67±0.29 mm.PVA/AgNPs film with 4%nano-silver content was selected to preserve fresh noodles leaf and determine the quality changes of fresh noodles leaf during the storage period at 4℃.The preservation results showed that 4%PVA/AgNPs film could significantly delayed the growth of total colony counts,maintained the color,pH and acidity of the fresh noodles leaf during the storage period.Furthermore,4%PVA/AgNPs film significantly reduced the cooking loss,improved the quality and the migration of the silver in the fresh noodles leaf,which the national standards.The above study showed that PVA/AgNPs film had the excellent antibacterial effect,and effectively maintained the quality of fresh noodle leaf and prolong the storage time,which can provide a new method for the packaging of noodle products.关键词
