Food UsesSodium bicarbonate was sometimes used in cooking vegetables, to make them softer, although this has gone out of fashion, as most people now prefer firmer vegetables that contain more nutrients. However, it is still used in Asian cuisine to tenderise meats.Baking soda may react with acids in food, including Vitamin C (L-Ascorbic Acid). Sodium bicarbonate is also used in breadings such as for fried foods to enhance crispness.Thermal decomposition causes sodium bicarbonate alone to act as a raising agent by releasing carbon dioxide at baking temperatures.The carbon dioxide production starts at temperatures above 80 °C. The mixture for cakes using this method can be allowed to stand before baking without any premature release of carbon dioxide.Medical usesSodium bicarbonate is used in an aqueous solution as an antacid taken orally to treat acid indigestion and heartburn.Sodium bicarbonate may also be used in an oral form to treat chronic forms of metabolic acidosis such as chronic renal failure and renal tubular acidosis.Sodium bicarbonate may also be useful in urinary alkalinization for the treatment of aspirin overdose and uric acid renal stones. It is used as the medicinal ingredient in gripe water for infants.
