Lightly toss slices with 1 tsp lemon juice per banana or a pinch of ascorbic acid. This step locks in brightness without adding noticeable flavor.
4. Flash-Freeze
Arrange slices in a single layer on a parchment-lined baking sheet—do not let them touch. Freeze for 1–2 hours, or until solid. This prevents clumping during long-term storage.
5. Vacuum Seal
Transfer frozen slices into vacuum bags. Seal tightly using a vacuum sealer.
