Effect of Antibacterial Paper on Toast Preservation

Abstract:

The effect of antibacterial paper on toast preservation was studied. A paper-plastic composite material obtained via the combination of antibacterial paper and PP film was used to package the toast to investigate its difference of the texture, color difference, water activity, total number of colonies and enthalpy value comparing with the toast packed only in PP film or unpacked. The toast packed in paper-plastic composite material showed slower deterioration of texture and color difference, reduction of water activity, effective suppression of total colony number increase and suspension of enthalpy raise. This paper-plastic composite material can avoid direct addition of preservatives to food, effectively prolonging the shelf life of toast.
