1. Foul or rancid odor: Fresh oatmeal should have a mild, pleasant aroma. If it smells off (you will definitely be able to tell) or has a sour odor, it may have gone bad. 2. Unusual appearance: Inspect the oatmeal for mold, discoloration, or the presence of any foreign objects. If you spot anything unusual, it's better to err on the side of caution. 3. Strange texture: Oatmeal should have a smooth and uniform texture. If it feels gritty, clumpy, or slimy, it may have deteriorated.
To maximize the shelf life of oatmeal, it is important to store it correctly. Follow these storage guidelines: Keep it sealed: Once opened, transfer the oatmeal to an airtight container or resealable bag to protect it from moisture and contaminants. Store in a cool, dry place: Choose a storage location away from heat and humidity. A pantry or kitchen cupboard is usually a suitable option. Avoid exposure to sunlight: Sunlight can degrade the quality of oatmeal. Keep it away from direct sunlight or store it in an opaque container.
