Fish preservation

Fish preservation involves techniques to prevent spoilage and extend freshness after catching or processing. Common methods include refrigeration and freezing, which slow bacterial growth. Salting and drying remove moisture that bacteria need to thrive, while canning and smoking also inhibit spoilage. Chemical preservatives like sodium benzoate may be used in some cases. Proper handling, cleanliness, and maintaining cold temperatures are essential to ensure fish remains safe and edible for longer periods. These methods help reduce waste, maintain quality, and ensure fish is safe for consumption.
