Transfer Behavior of Clove Oil/β-Cyclodextrin Inclusion Complex in Antibacterial Film Based on PVA
The antifungal PVA film was fabricated by addition of the clove oil/β-cyclodextrin (β-CD) inclusion complex into PVA. The migration of clove oil in different food simulation solution (A: 10% ethanol water. B: 50% ethanol water. C: 60% glycerin-water mixture. D: n-hexane) were evaluated by using solution food simulation and then treated with linear regression analysis. The diffusion coefficient was cultivated out by Matlab software. The migration of clove oil which was embedded by β-CD in PVA film was influenced by the quality of food simulation solution to a great degree and the relation among the migration rate was A>B>D>C. The film structure was loosed and the migration gallery was increased by adding clove oil/β-cyclodextrin inclusion complex. The migration amount in simulations was positively correlated with time and diffusion coefficient.This kind antibacterial film can be used in low water activity food system and kept long-term antibacterial action.
