- Abstract
In order to improve the antibacterial efficiency of food packaging system, the volatile carvacrol essential oil was loaded into halloysite nanotubes by the vacuum negative pressure method to obtain the carvacrol-halloysite nanotube compounds. FTIR, TEM,TGA,UV Spectrophotometer and DSC were used to analyze the composition, microstructure, loading ratio and thermal stability of the compounds. At the same time, the antibacterial properties of the compounds were studied by agar plate counting method. The results show that the highest loading ratio of carvacrol is 20%;the zein film containing a mass ratio of 8% CA-HNTs has obvious antibacterial efficacy against Escherichia coli and Staphylococcus aureus, and the maximum inhibition efficiency is 85% for Escherichia coli and 59% for Staphylococcus aureus; The prepared CA-HNTs have a significant increase in thermal stability and certain slow release. The CA release ratio is only 33.8% at 40 ℃ after 25 days of storage. The shelf life of food can be greatly extended when the CA-HNTs obtained are applied in the food packaging materials.
