Evidence Details
Additional source evidence: source values include 10:0, 9:1, 8:2, 7:3, 6:4.
for 0, 10, 20, 30, and 40 min (frequency: 40 kHz, power: 50 W)
AgNPs powders were added to 5 mL of absolute ethanol and ultrasonically dispersed using a XH-2008D ultrasonic instrument
The results showed that the SA: AgNPs ratio of 7:3 and the ultrasonic time for 30 min have the best comprehensive performance
the antibacterial activity of Escherichia coli (92.01%) was higher than that of Staphylococcus aureus (91.26%)
SA/AgNPs/APP films showed the lowest water vapor permeability value of 0.75 × 10−11 g/m·s·Pa
with tensile strength (TS) and elongation at break (E) at 23.94 MPa and 29.18%, respectively
this composite film can prolong the shelf life of strawberries for about 8 days at 4 °C
its antioxidant activity can reach 98.39%
