Curious why your ground cinnamon has become clumpy? Learn how moisture absorption is the main reason and how to properly store it.
1 Answer
Ground cinnamon clumps over time due to its hygroscopic nature, meaning it readily absorbs moisture from the air, causing the particles to stick together. This clumping is exacerbated by the presence of natural oils in cinnamon.
Detailed Explanation:
Ground cinnamon is derived from the inner bark of cinnamon trees. This bark contains natural oils and compounds that are responsible for cinnamon's distinctive aroma and flavor. These oils, combined with cinnamon's hygroscopic properties, contribute to clumping. When exposed to air, ground cinnamon absorbs moisture. This moisture dissolves some of the soluble compounds on the surface of the cinnamon particles. As the moisture evaporates, these dissolved compounds act like a glue, binding the particles together and forming clumps. The higher the humidity, the faster and more pronounced the clumping will be. Furthermore, the natural oils present in cinnamon can also become sticky over time, further contributing to the clumping effect. The finer the grind of the cinnamon, the more surface area is exposed, making it even more susceptible to moisture absorption and clumping.
Pro Tip:
To prevent cinnamon from clumping, store it in an airtight container in a cool, dry place away from humidity and direct sunlight. Adding a few grains of uncooked rice to the container can also help absorb excess moisture.
