Can you refreeze partially thawed uncooked abalone?

It is generally not advisable to refreeze any food item, including partially thawed uncooked abalone, once it has been thawed as the freezing and thawing process can lead to changes in the texture and quality of the food. This is because ice crystals form during freezing, which can damage the product's structure and lead to a loss of nutrients.

Additionally, refreezing thawed food can also increase the risk of bacterial growth, as bacteria may have multiplied during the initial thawing process. Therefore, it is generally recommended to cook partially thawed or previously frozen seafood such as abalone immediately upon thawing and avoid refreezing it.
