Homemade applesauce can be frozen for up to a year, while commercially made applesauce maintains the best quality when frozen for up to two months. Keep both types of applesauce in a freezer that maintains a temperature of 0 F to prevent the growth of bacteria.
Cool homemade applesauce thoroughly in the refrigerator before freezing, and pack it in freezer-safe bags or containers, leaving 1 inch of space free to allow it to expand. Transfer store-bought applesauce to airtight, freezer-safe bags or containers before freezing. Use freezer labels and a permanent marker to add the expiration date to the container.
