vacuuming in a jar will keep them from getting crushed.

i have both size attachments for vacuuming jars with a foodsaver.
i dont really use them, but i have and it works.
it is fun opening a jar and getting that nice whooosh of air entering.

The purpose is to remove the oxygen present in the air to prevent interaction/degradation.

sure the seals work well, but they hold that oxygen in unless you suck it out first.
