  1. 1Step 1

    Cool quickly: shallow containers, into the fridge or freezer within 2 hours.

  2. 2Step 2

    Portion into freezer bags or airtight tubs, leave headspace for liquids, and label with the date.

  3. 3Step 3

    Thaw in the fridge and reheat to 165°F (74°C) until steaming.

Reheating

How to reheat mung bean sprouts safely

1

Reheat to 74°C (165°F)

Check the thickest part with a food thermometer; it should be steaming hot all the way through.

2

Only once

Reheat just the portion you will eat. Each cool-and-reheat cycle gives bacteria another chance.

3

Cover and stir

In the microwave, cover the dish and stir halfway so there are no cold spots.

4

From the freezer

Thaw in the fridge first, or reheat straight from frozen and allow extra time.

The 2-hour rule

Mung bean sprouts left out overnight

Mung bean sprouts left at room temperature for more than 2 hours (1 hour above 90°F / 32°C) should be thrown away. Bacteria multiply fastest between 40°F and 140°F, and reheating does not remove every toxin they make.

Best-by and use-by dates on mung bean sprouts

Best-by and sell-by

FoodKeeper gives unopened mung bean sprouts 4–6 weeks in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.

Past the date

For perishable mung bean sprouts, the storage clock matters more than the label: if it has been in the fridge longer than 4–6 weeks, discard it even before the printed date.
