Are your baking soda and baking powder aluminum free?

Bob's Red Mill packages baking soda mined from the earth. Like most products that we sell, our baking soda is minimally processed and a product of nature with nothing added and nothing taken out. There may be naturally occurring traces of aluminum in our baking soda. While the amount of aluminum in our baking soda (if any) is minimal, we feel omitting the term "aluminum free" from our packaging will avoid any confusion with our customers.
