How Long Do Mung Bean Sprouts Last?
How to identify fresh mung bean sprouts and avoid spoilage.
Mung bean sprouts last about 3–5 days in the refrigerator when kept dry.
Mung bean sprouts are a staple in many cuisines, prized for their crunchy texture and earthy flavor. Because they have high moisture content and a porous structure, they can become slimy or develop mold quickly if not stored correctly. To maximize their shelf-life, keep them in the refrigerator in an airtight container or a breathable bag, ensuring they stay as dry as possible. When they begin to lose their snap or show signs of moisture buildup, it is time to evaluate their safety for your next meal.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long do mung bean sprouts last in the refrigerator?
Mung bean sprouts stay fresh for 3–5 days in the refrigerator if kept dry. Avoiding excess moisture is key to preventing spoilage.
Can I wash mung bean sprouts before storing them?
It is best to wash sprouts immediately before use. Storing them after washing adds surface moisture, which accelerates sliminess and mold growth.
Why do my sprouts get slimy so quickly?
Their porous structure and high water content make them highly susceptible to bacterial growth if they sit in excess moisture or warmth.
Can I freeze mung bean sprouts?
You can freeze them, but the texture will become mushy upon thawing. They are best used in cooked dishes rather than raw applications if frozen.
Is it safe to eat raw mung bean sprouts?
Sprouts can harbor bacteria due to their warm, humid growing conditions. Always wash them thoroughly and consider cooking them to reduce safety risks.
Keep those sprouts dry and chilly! If they start to slide off your spatula or smell funky, it's time to say goodbye.
