Seafoods containing many ice crystals should be cooked immediately. Freezer burn is dehydration or drying that occurs on the surface of a product if it is improperly wrapped. The food is of such poor quality, we do not recommend eating it. To prevent freezer burn, the package must be sealed airtight in moisture vapor proof containers or wrap. Freezing does not improve the quality of the product.
Frozen food is only as good as the quality of the fresh food.
So, select only high quality products at optimum maturity and freshness. When thawed, surviving microorganisms can grow again. Add only the amount of food that will freeze in 24 hours, usually about two or three pounds of food per cubic foot of freezer space. Overloading the freezer slows down the freezing rate resulting in foods of lower quality. The higher the temperature, the faster the quality and nutrient levels will drop.
