Can vegetables be raw (cold) packed?
Home-canned foods keep their quality longer when air is removed from food before the jar is sealed. Hot packing is the best way to remove air. It also "shrinks" food so more will fit into the jar, keeps food from floating, increases vacuum in sealed jars and improves shelf life. Color and flavor of hot packed foods is superior to raw packed foods. It is safe, however, to raw pack some vegetables if safe processing directions are used. See GH 1454 "Preserve Your Garden Delights" for directions.
