Salmon Muscle Adherence to Polymer Coatings and Determination of Antibiotic Residues by Reversed-Phase High-Performance Liquid Chromatography Coupled to Selected Reaction Monitoring Mass Spectrometry, Atomic Force Microscopy, and Fourier Transform Infrared Spectroscopy

Figure 2

(a) The highest localized salmon adhesion occurred in samples stored for 16 months. It is possible to observe several zones of adhesion displayed in grey color of varied intensities. The white surfaces showed no evidence of changes on the PET coating (×10). The lines and numbers correspond to points of spectroscopy analyses [17]; (b) PET polymer surface with small residues (grey) of salmon muscle that remained attached after the application of urea solution (×10) [17]; (c) muscle morphology with peptide multilayers on PET surface with manufacturing defects (SEM); (d) muscle residues strongly adhered to the pore edge of the polymer coating posturea treatment (SEM).
