Here are the key points about packaging in food preservation:
- Packaging protects food from physical, chemical, and biological spoilage and deterioration. It protects from damage, contamination, insects, microorganisms, air, light, etc.
- There are different packaging materials for fish products including flexible/soft packaging (hard plastics, foils, retortable pouches, cling wrap), and rigid packaging (metal cans, glass containers).
- Packaging extends the shelf-life of foods like fish. Vacuum packaging prevents oxidation and allows dried fish to last up to a year.
- Packaging provides information to consumers through labeling and promotes the marketability of the product. It makes handling and storage more convenient
