Osmosis is the movement of water across a semipermeable membrane, like a cell membrane. Salting removes the water, so living things (like bacteria and fungus) cannot  grow.]]> 2021-08-30 16:07:14 UTC https://padlet.com/ashleydgruber1/tgulq33yl0apgyxp/wish/1704860849 Methods of food preservation: benjaminho4 https://padlet.com/ashleydgruber1/tgulq33yl0apgyxp/wish/1705163157 Canning has a sealed "environment" so it kills everything inside

it slows down the activity of disease causing bacteria's
oxygen causes fats to oxidize or become rancid, turns food colors that don't look appetizing. enzymes that ripen fruits on trees and vegetables on stalks or vines continue to ripen them after you pick them.]]> 2021-08-30 18:40:31 UTC https://padlet.com/ashleydgruber1/tgulq33yl0apgyxp/wish/1705171811 freezing ashleydgruber1 https://padlet.com/ashleydgruber1/tgulq33yl0apgyxp/wish/1713473387 2021-09-02 18:35:05 UTC https://padlet.com/ashleydgruber1/tgulq33yl0apgyxp/wish/1713473387 ashleydgruber1 https://padlet.com/ashleydgruber1/tgulq33yl0apgyxp/wish/1713477687 2021-09-02 18:37:15 UTC https://padlet.com/ashleydgruber1/tgulq33yl0apgyxp/wish/1713477687
