How to Store Arrowroot Powder for Maximum Freshness
Keep your arrowroot powder dry and stable in the pantry.
Arrowroot powder lasts 4–5 years when stored in a cool, dry pantry.
Arrowroot powder is a versatile gluten-free thickening agent derived from the arrowroot and other tropical tubers. Because it is a shelf-stable starch, it behaves similarly to other flours or starches like tapioca or cornstarch. To maintain its quality, it must be kept away from moisture and strong odors. When stored correctly in an airtight container within a pantry, it retains its texture and thickening properties for several years. If exposed to humidity, the powder may clump or develop mold, which is why proper sealing is essential for long-term storage.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
