Tag: How to store almonds

According to the Almond Board of California, raw almonds can have a shelf life of up to two years when stored properly under controlled conditions. However, the actual answer to how long can you keep almonds in the pantry is often much shorter, depending on factors like processing, packaging, and the specific storage environment. Heat, light, and air are the primary culprits that cause almonds to go rancid prematurely.

Over 50% of the fat in almonds is monounsaturated, a delicate healthy oil susceptible to degradation. This high fat content is the primary reason why almonds need to be refrigerated, as the cooler temperatures significantly slow the oxidation process that causes rancidity. While supermarket nuts sit on shelves for extended periods, they are typically vacuum-sealed or treated, and once opened, they are at risk of spoiling quickly if not properly stored at home.

Almonds can stay fresh for up to two years when stored correctly. However, improper storage can lead to rancidity. Protecting almonds from heat, light, air, and moisture is key to preserving their quality.
