Defrosting of Frozen Food
Partially thawed or defrosted foods should be used as soon as
possible. Cold air preserves the food but it does not destroy
microorganisms which rapidly activate themselves after defrosting and
make foods perishable.
Partial defrosting reduces the nutritional value of foods, especially of
fruits, vegetables and ready-made meals.
