Storing almond flour properly is essential to maintain its freshness and prevent it from going rancid. Here's how to store almond flour and information on its shelf life: Transfer the almond flour to an airtight container or a resealable bag and seal well to prevent air and moisture from getting in. Label the container with the date you opened the almond flour, so you can keep track of its freshness. Store it in a cool, dry place, away from direct sunlight, heat, near the stove, oven or humidity. While it's not required, storing almond flour in the refrigerator or freezer can help extend its shelf life. The shelf life of almond flour depends on several factors, including how it's stored and the quality of the almond flour. When stored in a cool, dry place at room temperature, almond flour can typically last fresh for up to 6 months. If stored in the refrigerator, it can last longer, typically up to 1 year. It's important to note that almond flour is susceptible to absorbing odors and moisture, so it's essential to keep it well-sealed and protected. If you want to store almond flour for an extended period, you can freeze it. Properly sealed almond flour can last in the freezer for up to 2 years. Freezing can help maintain the flour's quality, but ensure it's in an airtight container to prevent freezer burn. If you notice any signs of spoilage, such as a rancid smell or an unusual color, it's best to discard it and obtain a fresh batch.
