Pro Tips:
1. Oats can technically last forever if stored properly. Due to their low moisture content and natural antioxidants, oats have an impressive shelf life, often lasting years without going bad.
2. Rolled oats have a higher chance of going rancid compared to steel-cut oats. This is because the outer layer, which is removed during the rolling process, contains healthy oils that can eventually turn stale.
3. Although oats don’t spoil easily, they can absorb odors from their surroundings. If stored near strong-smelling foods like spices or onions, oats may develop an unappealing taste or aroma over time.
4. If you accidentally purchased rancid oats, don’t throw them away just yet! You can repurpose them as a natural exfoliating scrub for your skin. By combining oats with honey or yogurt, you can create a rejuvenating face mask or body scrub.
5. Contrary to popular belief, oats don’t need to be refrigerated or frozen to maintain freshness. Rather, it’s best to store them in an airtight container in a cool, dry place like a pantry or cupboard.
