Does baking soda or baking powder take gas out of beans?

Yes it does! I soak the beans for at least 6 hours, then boil them for a few minutes. Just boiling will cause the beans to release gas too. Yet, to get rid of all the gas, remove the beans from heat and add a few tablespoons of baking soda in the boiled beans. You will see a green liquid come from the beans, which THAT is the gas. Drain the liquid from the beans, rinse the beans and then cook the beans. You don't have to worry about anyone totting while eating your beans meals with using the baking soda.
