Prepare NatureSeal browning inhibiting solution according to package directions by mixing one packet with 8 ounces of cold water. Transfer liquid into a flat 9×9 baking dish or smaller baking pan.

Remove apples from the dish, transfer into a zip bag or storage container, and repeat the process with remaining apples.
