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,
Cricket flour at 40%–50% . It takes approximately 15,500 L of water to produce 1 kg of live animal weight of beef. Out of which only 40% (0.4kg) is edible. Using the same math, this study showed that it takes only 2,500 L of water to produce 0.8kg of edible cricket protein. That means 80% less water is used in order to produce double the amount of final edible product. Cricket flour also promotes sustainability by eliminating the use of traditional grain-based flour (which is oftentimes processed heavily and takes longer to produce). Although cricket flour's nutrition may partially be based on
