Rancid oil makes stale almonds taste bad. Spoiled almonds are not poisonous, but fats are no longer beneficial. It's possible that rancid fats may contribute to chronic health problems if consumed frequently. Yes, almonds spoil when stored for too long or under suboptimal conditions.
Almonds are most likely to spoil if stored improperly. Inadequate storage conditions include exposure to heat, light and oxygen. Under such circumstances, almonds will produce oil that will spoil them. Almonds have natural antioxidants that promote a long lifespan.
In fact, they can retain their properties longer than many other nuts and can be transferred from one year to the next while maintaining certain safeguards and controlled conditions. To extend the shelf life of roasted products, packaging is crucial. Do raw almonds expire? They become rancid, change color, become moldy, or dry out. This is a clear indication that they have expired and should be discarded.
Or it reduces oxidation and eliminates any odors, which almonds easily absorb due to their high fat content. Since shelled almonds have their natural covering, you can store them in your pantry for 6 months without spoiling them. Keep almonds in the original container if they are thick and strong enough to block moisture and prevent almonds from picking up unwanted odors. And when it comes to almond snacks, it's much better to check the label than to rely on that estimate.
Depending on how quickly you eat them, it's quite possible that you'll find almonds that are past their prime, but haven't yet developed any rancid or strange taste due to oxidation. If you store almonds under the right conditions, you can eat them for months after the expiration date. The self-oxidants in almonds oxidize these fats when they are exposed to moisture, light, heat or oxygen. On the other hand, raw almonds, especially those that have undergone some type of reduction in size, have a reduced lifespan due to increased humidity and surface area.
When you notice that almonds change color, smell sour, or taste bitter before their expiration date, it doesn't make them good. The University of California says you can store them for about a year, while the California Almond Board reports that it's approaching two years. Shelled almonds are exposed to moisture, oxygen and heat, meaning they will last less than four months. So if you've ever stored almonds in warm temperatures for a couple of months and they've gone rancid, consider moving them to a cooler place, such as the fridge.
Not only are almonds a great and filling snack, but they're packed with health benefits in a small, compact size. While you'll most likely buy shelled almonds, you might be wondering if there's a difference between skinless and shelled almonds. Because they expose less surface area to the atmosphere, whole nuts last longer than sliced or sliced almonds.
