Baking Soda question

[cookiejar]

Okay, I'm willing to look like an idiot to ask this question. I highlighed the info about baking soda and my question is: is this true? indefinite?

 

Baking Soda

 

This gritty powder is sodium bicarbonate also called sodium acid bicarbonate (NaHCO3), a mild alkali. It is used in baking to leaven bread and does so in the same manner as baking powder. When combined with an acid ingredient, the bicarbonate reacts to give off carbon dioxide bubbles which causes the baked good to rise. If kept well sealed in an air- and moisture-proof container its storage life is indefinite. If kept in the cardboard box it usually comes in, it will keep for about eighteen months. Do keep in mind that baking soda is a wonderful odor absorber. If you don't want your baked goods tasting of whatever smells it absorbed then keeping it in an airtight container is an excellent idea.

You may want to submit the question to Arm & Hammer to see what they say. I've found this same statement on a couple other sites. On the Joy of Baking site and the Recipes4Us site both say the same thing.

Yes, but it's tricky. Since it does absorb moisture & odours, be careful. I keep mine in a glass jar for baking.

It's true if you keep it stored correctly like the others said.
