The study demonstrates that plasma-modified bilayer films improved quality preservation in rainbow trout, reducing microbial counts and lipid oxidation.
Key Points
Shelf-life quality preservation was significantly better in bilayer films compared to low-density polyethylene, delaying spoilage.
Total volatile basic nitrogen in bilayer samples reached 39.22 mg N/100 g, while controls reached 68.14 mg N/100 g by Day 12.
Packaging approach involved cold plasma treatment of polylactic acid with chitosan–zein nanoparticle bilayers to enhance trout quality.
This method highlights an effective sustainable alternative to traditional fish packaging methods.
