Rice flour typically lasts for 4-6 months in the summer if stored properly in a cool, dry place. High humidity and temperatures can significantly reduce its shelf life.
Rice flour, like other flours, is susceptible to spoilage due to its starch and oil content. In the summer months, increased heat and humidity create an ideal environment for mold growth and insect infestation, which can drastically shorten its shelf life. The oils in the rice flour can also turn rancid more quickly in warmer temperatures. To maximize the shelf life of your rice flour during the summer:
Store in an airtight container: Transfer the rice flour from its original packaging to an airtight container as soon as you open it. This will help prevent moisture absorption.
Keep it in a cool, dry place: The pantry is often the best place, but if your pantry gets very warm, consider storing it in the refrigerator or freezer. The refrigerator can extend the shelf life to 6-8 months, and the freezer can extend it to a year or more.
Check for signs of spoilage: Before using rice flour, always check for any signs of spoilage, such as a musty odor, discoloration, or the presence of insects. If you notice any of these signs, discard the flour immediately.
To further protect your rice flour, consider adding a bay leaf to the storage container. Bay leaves are a natural insect repellent and can help prevent infestations, especially during the warmer months.
