Quick bread leavening agents include a weak base, such as baking soda (sodium bicarbonate) plus a weak acid, such as cream of tartar, lemon juice, or cultured buttermilk, to create an acid–base reaction that releases carbon dioxide. (Quick bread leavened specifically with baking soda is often called "soda bread".) Baking powder contains both an acid and a base in dry powdered form, and simply needs a liquid medium in which to react. Other alternative leavening agents are egg whites mechanically beaten to form stiff peaks, as in the case of many waffle recipes, or steam, in the case of cream puffs. Nevertheless,
Eti Soda and by Eti Maden with 26%. Trona ore is extracted by solution mining method. Hot water is injected into the trona ore deposit underground through bore holes drilled, which dissolves trona ore. The trona solution is pumped up and is processed to soda products as soda ash (sodium carbonate, NaCO) and baking soda (sodium bicarbonate, NaHCO). The soda ash is mainly used in the glass production. Products of Eti Soda are exported all over the world, especially to European countries. From 2009 to 2013, the value of soda ash exports to 53 countries reached US$1 billion. The annual production capacity
