4. Vacuum Seal the Bag
Follow the instructions for your vacuum sealer to remove air and seal the package securely. Ensure that the seal is tight, with no air pockets left inside.
5. Store Properly
Place the vacuum-sealed bags in a cool, dark place. Label each bag with the date of sealing and the type of oatmeal to keep track of their age.
Signs of Spoilage: How to Tell if Your Oatmeal is Bad
Even vacuum-sealed oatmeal can spoil if not stored properly. Knowing what to look for can help you avoid eating spoiled food.
1. Smell Test
If the oatmeal emits a musty or rancid smell, it’s a strong indication that it has spoiled. Fresh oatmeal should have a mild, nutty aroma.
2. Visual Inspection
Examine the vacuum-sealed bag for any signs of moisture, mold, or changes in color. If you see condensation inside the bag or any unusual discoloration, it’s best to discard it.
