Why moisture content doesn't tell you how a dehydrated vegetable will cook

Two dehydrated vegetables can carry the same moisture percentage on the spec sheet and still behave nothing alike in a pot of boiling water. The number that actually predicts kitchen performance sits one line further down.

Why a retort pouch doesn't need a fridge or a preservative
