ABSTRACT In this study, the cellulose acetate phthalate (CAP) film loaded with tannic acid (TA) was prepared in the work using the electrospinning method. The addition of TA increased both the conductivity and the viscosity of the electrospinning solution, which resulted in a higher average fibre diameter (1.14 ± 0.30 to 1.32 ± 0.32 μm). The electrospun films exhibited antibacterial activity, with the highest inhibition zone diameter values of 8.3 mm against Escherichia coli and 8.5 mm against Staphylococcus aureus , as well as antioxidant activity with a maximum free radical scavenging rate at 41%. The combined benefits of TA‐loaded electrospun CAP film and vacuum skin packaging on the quality of minced beef were investigated. It has been found that the microbial, physical and chemical deterioration of the minced beef was effectively retarded; hence, it extended its shelf life by an extra 2 days. In conclusion, the TA‐loaded electrospun CAP film is highly effective in preserving the quality of minced beef using vacuum skin packaging.
