I have to take air from jar of dehyrated fruit

I would put the fruit in a Ziploc bag, partial seal it leaving a small opening for a straw. Insert straw and suck out the air. Quickly remove straw and close the bag completely.

In order to vacuum seal in jar, you will either need a container that has an air valve that can hook up to a vacuum pump; a vacuum chamber; or FoodSaver jar sealer.

What do you mean?
Create a vacuum? If Yes, why?
If other, What?
