Polycaprolactone/polyvinyl pyrrolidone nanofibers developed by solution blow spinning for encapsulation of chlorogenic acid

Abstract Study on the application of nanofibers in food active packaging has been a research hotspot recent years. In this work, solution blow spinning (SBS) was applied to rapidly fabricate polycaprolactone (PCL), polyvinyl pyrrolidone (PVP), and PCL/PVP nanofibrous films encapsulate chlorogenic acid (CGA). All showed uniform smooth nanofibers, Fourier transform infrared spectroscopy X-ray diffraction proved success mixed PCL PVP. With increase PVP content, thermal stability improved. The (weight ratio 4:1) film possessed better mechanical properties than because stronger fiber–fiber interactions. addition endowed hydrophobic surfaces films, had water vapor barrier ability. (4:1) exhibited best long-term continuous release CGA during 72 h. no inhibition against Staphylococcus aureus Escherichia coli due low encapsulation efficiency, but good antimicrobial activity. above results suggested that developed by SBS possess promising prospects packaging.
