When it comes to the rate of spoilage, seafood sets itself apart from meat found on land.

Water Content:

Seafood has a higher water content compared to land-based meat, making it a conducive environment for bacteria to thrive.

Lack of Collagen:

With lower levels of collagen, seafood offers less resistance to bacteria, allowing them to penetrate the flesh more easily.

Polyunsaturated Fats:

Seafood, particularly fish, contains high levels of polyunsaturated fats, such as omega-3 fatty acids.

While beneficial to health, these fats oxidize more readily, contributing to quicker spoilage.

Cold Water Enzymes:

Seafood from cold water environments possesses enzymes adapted to cold temperatures, causing it to spoil faster when stored at regular refrigerator temperatures.

Enzymatic Breakdown and Rotting:

Enzymes that break down fish meat are not as effectively slowed down by refrigeration as enzymes in meat from land animals.

Refrigeration and Packaging:

While proper refrigeration and packaging can mitigate spoilage, seafood's unique composition requires additional care to maintain freshness.

Seafood's faster spoilage compared to meat from animals on land is attributed to its higher water content, lower collagen levels, higher polyunsaturated fat content, enzymes adapted to cold water, and refrigeration challenges.

Understanding these factors can help consumers and food providers take the necessary precautions to ensure the freshness and safety of seafood offerings.
