The effects of fatty acids with different chain lengths (10–18 carbons) and degrees of unsaturation (0–2) on the moisture content, water solubility, water vapor permeability (WVP), light transmission, thickness, in vitro digestion and release properties of potato starch-fatty acid films (PS-FA films) were studied, and the PS-FA films were used for packing chicken meat. Results showed that PS-FA films had lower moisture content, water solubility, WVP, light transmission, and vitamin C release values and higher IR spectra ratio R1047/1022, slow...
