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. Spoiled almonds won't hurt you if you've only eaten a small amount.
But if consumed regularly, rancid fat can cause health problems, some of which can be chronic. If you love almonds, you may have noticed that sometimes a package that has been in storage for a while doesn't taste very good. By now you know that storing almonds properly is important to prolong their lifespan. Maintaining almond quality during long-term storage under ambient conditions is a challenge in emerging export markets, such as China, which may have highly variable temperatures and relative humidities, depending on season and region.
This is especially true if you keep almonds in your pantry near a packet of grains or other seeds that insects love, such as weevils. Shelled almond kernels will probably be fine even if you leave them unprotected in the fridge for a couple of months. That means the refrigerator or freezer are the two best places to store that leftover package of almonds. So, if you take out a pack of almonds and see mold on the seeds, that's a sure indicator that the nuts have gone rancid or rancid.
Almonds are known to absorb the aromas and flavors of other foods; you don't want your package to smell or taste like garlic. Store the almonds in an airtight container in the refrigerator or freezer if you want them to keep the best quality for more than a year. When preparing this nut milk, remember that homemade almond milk only lasts a couple of days, so don't overdo it. The typical scenario is for those almonds to go rancid, meaning they look and (often) smell good, but they taste strong and bitter.
As you can see, and as is the case with other nuts, the colder the storage location, the longer the almonds will last. After reading the previous section, you already know that almonds usually maintain a reasonably good quality for much longer than the printed date suggests. Because of these interactions, almond shelf life guidelines should specify the product and storage conditions. There are many factors that come into play when it comes to the lifespan of almonds, including the type of seeds (raw or processed) and how they are stored (whether a package is opened or not).
