Flour Additives 554<br />

NAME: Sodium hydrogen carbonate<br />

CATEGORY: Flour additive<br />

FOOD USE: Baked goods/ Baking powder<br />

SYNONYMS: Sodium bicarbonate/ Bicarbonate of soda/ Baking soda/ E500<br />

FORMULA: Na HC O3<br />

MOLECULAR MASS: 84.01<br />

PROPERTIES AND APPEARANCE: White crystalline powder<br />

MELTING RANGE IN °C: Decomposes at 50<br />

DENSITY AT 20°C (AND OTHER 2.22<br />

TEMPERATURES) IN g/ml:<br />

PURITY %: >99<br />

WATER CONTENT MAXIMUM IN %: 0.25<br />

HEAVY METAL CONTENT MAXIMUM IN 5<br />

ppm:<br />

ARSENIC CONTENT MAXIMUM IN ppm: 2<br />

SOLUBILITY % AT VARIOUS TEMPERATURE/pH COMBINATIONS:<br />

in water: @ 20°C 9.5%<br />

FUNCTION IN FOODS: Raising agent; alkali. On reaction with an acid, sodium bicarbonate releases carbon dioxide gas. This<br />

reaction provides the basis for chemical leavening systems. The carbon dioxide produced aerates the<br />

dough or batter during mixing and baking, thereby giving the product an enhanced volume and a<br />

lighter texture<br />

ALTERNATIVES: Ammonium hydrogen carbonate (for biscuits); potassium hydrogen carbonate (for biscuits)
