Just to back up what Jason said I had freezer S7 15&18 in soak since 2019, bulk pots I top up my hook baits from every now and then. I had 1 pot in the bait soak, perfectly fine, the other in the liquid food, again perfectly fine but the baits did swell a little in the food, I don't see that as a problem, might be for some.
I have thrown these now and started afresh for bulk but my hookbait tubs still have them in and they still catch very well.
