Apple options appear in several formats, including puffed snacks, freeze-dried apple pieces, pureed applesauce pouches (squeezable), and sauce/puree pouches.
Many products are shelf-stable until opened, come in squeezable or resealable-cap pouches, and are marketed as convenient for lunch boxes, backpacks, and travel.
At least one baby snack is labeled Stage 3 and for babies 8 months and older; the packaging also references self-feeding milestones appropriate for that stage.
Several product descriptions note resealable caps and advise refrigerating after opening and serving within 24 hours.
Freeze-drying is used for the sliced apple snack; it’s described as freeze-dried pieces sold in a resealable pouch.
Depending on the pouch, one provides either 1/3 cup (noted as about 16.5% of the USDA 2-cup daily recommendation) or 1/4 cup (noted as about 12.5% of that recommendation).
