How long do bouillon and dry soup mixes last?

FoodKeeper gives bouillon and dry soup mixes 1 year unopened, as a guide to quality. Once opened, that's 1 year in the pantry.

How to store it

Keep them sealed and away from steam: don't store them right beside the stove, because they take in moisture.

Keep it cool and dry. USDA says temperatures below 85°F are best, and to avoid anywhere above or beside the stove, under the sink, or in a damp garage or basement. Reseal opened packs, or decant them into something airtight.

What to look for

Cubes that crumble or darken have lost quality. Throw out anything damp or moldy.

USDA says spoiled food develops an off odor, flavor or texture, and that if it has, you shouldn't eat it.

Worth knowing

They have the same time opened as unopened in FoodKeeper: a year each. Foil-wrapped cubes in an opened box are protected, but loose powders aren't.

How it works

FoodKeeper is USDA's food storage database. Its figures are guides to quality for food stored at cool room temperature, not safety cut-offs, and we show them as USDA gives them. FoodKeeper counts this from the date of purchase. Opened times start when you open the pack.

Where FoodKeeper gives no figure, we say so instead of guessing. The date printed on a package is the manufacturer's, and it's about quality except on infant formula.
