When used alone, sodium bicarbonate reacts to give products a biller, soapy flavor. Thus it is always combined with a leavening acid.

It is unstable to heat, neutral or alkaline pH, and can be easily leached out of foods. Thiamin is destroyed by sulfur dioxide (often used as a food preservative), potassium bromate (oxidizing agent used in bread) and by sodium bicarbonate (in chemically leavened breads).
