Can you keep refreezing milk?

Yes, you can refreeze thawed milk under specific conditions.

Refreezing Thawed Milk: What You Need to Know

According to the CDC, refreezing thawed milk is permissible if the milk still contains ice crystals. This indicates that the milk has not completely thawed and is still at a safe temperature for refreezing.

Here's a breakdown:

  • When it's okay to refreeze:
    • If you can still see ice crystals in the milk, it's generally safe to refreeze.
    • This means the milk hasn't fully thawed and the temperature hasn't risen into the danger zone for bacterial growth.
  • What to do if there are no ice crystals:
    • If the milk has completely thawed (no visible ice crystals), the safest practice is not to refreeze it.
    • Instead, use the thawed milk within a couple of days and follow normal milk storage guidelines.

Practical Steps for Refreezing Milk

If you do refreeze milk, here are some tips to ensure quality:

  • Strain ice crystals: If you have any concerns about refreezing, you can strain the ice crystals.
  • Use promptly: Once the milk is thawed after the second freezing, use it as quickly as possible.
  • Monitor quality: Pay attention to the milk's appearance, smell, and taste. If you notice any changes, discard it.

Why Refreezing Can Affect Milk

While refreezing is possible in certain cases, be aware it may affect milk's texture and quality:

  • Texture changes: Refreezing can cause the milk to become slightly grainy or separated.
  • Quality reduction: Repeated thawing and refreezing can degrade the quality of the milk proteins and fats.

Safe Milk Storage Guidelines

Here are a few reminders for storing milk:

  • Keep refrigerated: Keep milk refrigerated at or below 40°F (4°C)
  • Use within date: Consume milk by the "use by" or expiration date.
