Should plant-based milk be refrigerated after opening?

Question

Do you need to refrigerate your plant-based milks after opening? Learn the proper storage guidelines to ensure they stay safe to drink.

Answer 1

Yes, plant-based milk should be refrigerated after opening, just like dairy milk, to prevent spoilage and maintain its quality.

Detailed Explanation:

Plant-based milks, such as almond milk, soy milk, oat milk, and coconut milk, are susceptible to bacterial growth once the container is opened and exposed to air. Refrigeration slows down this process significantly. The cool temperature inhibits the proliferation of microorganisms that can cause the milk to sour, develop off-flavors, or become unsafe to consume. Most plant-based milk cartons will have instructions to refrigerate after opening, and it's crucial to follow these guidelines. Typically, opened plant-based milk will stay fresh in the refrigerator for about 7-10 days, but it's always best to check for any signs of spoilage before consuming. These signs include a sour smell, changes in texture (like thickening or curdling), or any unusual appearance.

Pro Tip:

To maximize the shelf life of your plant-based milk after opening, store it in the coldest part of your refrigerator, typically the back of the bottom shelf, rather than in the door where temperatures fluctuate more.
