Unopened in fridge1-3 days
Signs of Spoilage
Slimy texture, strong musty or sour odor, discolored (yellowing or dark spots), mushy appearance.
How to Check
Visually inspect for any darkening, yellowing, or translucent, wet spots. Gently touch to check for sliminess. A fresh, mild, earthy scent is normal; any strong, unpleasant smell indicates spoilage. NEVER taste-test for spoilage.
Storage Tips
Bean sprouts are highly perishable and prone to bacterial growth. Use them as quickly as possible after purchase. Do not wash until immediately before use to prevent premature spoilage.
Opened in fridge1-2 days
Signs of Spoilage
Accelerated sliminess, strong off-odor, browning or yellowing, wilting.
How to Check
Check for sliminess, especially on the cut ends. Sniff for any sour or strong, unpleasant smell. Visually inspect for any dullness, yellowing, or dark spots. They should be crisp and white/pale yellow. If they look or smell off, discard them.
Storage Tips
Transfer opened sprouts to an airtight container lined with a paper towel to absorb excess moisture. Some suggest submerging in cold water and changing daily, but this can also introduce contamination if not done hygienically. It's best to use them the same day or the next.
Cooked leftovers in fridge3-4 days
Signs of Spoilage
Mold growth, sour or unpleasant odor, unusually mushy texture, discoloration (darker than when cooked).
How to Check
Visually check for any fuzzy mold. Smell for a sour, rancid, or 'off' aroma. The texture might become excessively soft or watery. If in doubt, throw it out.
Storage Tips
Cool cooked dishes rapidly (within 2 hours) and store in an airtight container. Reheat thoroughly to an internal temperature of 165°F (74°C). Do not reheat multiple times.
Freezer (blanched)1-2 months
Signs of Spoilage
Severe freezer burn (dry, discolored spots), strong 'freezer' odor, mushy and watery texture upon thawing, loss of flavor.
How to Check
Visually inspect for excessive ice crystals or dry, white patches (freezer burn). Upon thawing, they will be very soft and watery. If they have an off-odor after thawing, discard them.
Storage Tips
To freeze: Blanch sprouts for 1-2 minutes in boiling water, then immediately plunge into ice water. Drain very well, pat dry, and freeze in a single layer on a baking sheet before transferring to airtight freezer bags or containers. Label with the date. Do not thaw and refreeze.
