Question which preserves food longer, zip lock or aluminum foil?
Answer Hi Gerardo,
It depends -- if they both are wrapped tightly so no air can get to the food -- they are both effective. Many people actually use both to ensure several layers between the food and the freezer air.
Heavy duty aluminum foil can be used as a freezer wrap. Because it can be torn or punctured easily it is wise to use an overwrap. Light weight (household) aluminum foil is not satisfactory for home freezing.
Good freezing materials include rigid containers made of aluminum, glass, plastic, tin or heavily waxed cardboard; bags and sheets of moisture-vapor resistant wraps; and laminated papers made specially for freezing.
Hope this helps. If you have additional questions, please let me know.
