Expiration & Storage Tips
When does margarine expire?
Margarine, when unopened, can last anywhere from 8-10 months past the printed date on the package. Once you've opened it, you should use it within a month for the best quality, although it will likely still be safe to consume for another 2-3 months if stored correctly. If you choose to freeze margarine, it can last about a year. But remember, the texture may change after being frozen, making it less satisfactory for spreading. In terms of homemade margarine, it typically lasts for 1-2 weeks in the refrigerator. Always remember to check for signs of spoilage before using it.
How do you tell if margarine is bad?
Margarine that's gone bad usually develops a strong, unpleasant odor and may also develop mold. Margarine that's old or has been improperly stored may exhibit changes in color, becoming pale or developing dark spots. The texture may also change, becoming lumpy, grainy, or oily. If you notice any of these signs, it's best to discard the margarine.
Tips for storing margarine to extend shelf life
• Keep margarine in its original packaging or a tightly sealed container to protect it from odors and contamination.
• Store margarine in the refrigerator, away from the door where temperature fluctuations are common.
• Use a clean knife each time when scooping margarine to prevent the introduction of bacteria.
• If you need to freeze margarine for extended storage, wrap it in a freezer-safe bag or wrap to protect against freezer burn and keep it separate from other frozen foods.
• When using frozen margarine, defrost it overnight in the refrigerator before trying to spread it.
