Yes, you can freeze JUST Egg egg substitute. We regularly freeze unopened bottles of JUST Egg. We freeze the bottles for up to a month. To unthaw we let the bottles sit in the refrigerator overnight; up to 2 days to unthaw.  The texture is a little lumpy after defrosting but just shake vigorously to reconstitute. You may need to shake the bottle if you see any separation. *Please note JUST Egg doesn’t recommend freezing.
