CHITTICK CARBON DIOXIDE APPARATUS
The Chittick Carbon Dioxide Apparatus is used to determine total carbon dioxide in prepared bakery mixes and self-rising flours. Bakery mixes may include, but are not limited to cake, biscuit, pancake, cookie, muffin, or other chemically leavened mixes. Carbon dioxide may be released from sodium, potassium, and ammonium bicarbonates (as sources of leavening gas) or calcium and sodium carbonates. A strong acid, e.g. sulfuric acid, is required to neutralize carbonate sources. This method can be used for systems that contain various leavening ingredients such as sodium aluminum sulfate, sodium acid pyrophosphate, sodium aluminum phosphate, monocalcium phosphate, dimagnesium phosphate, or organic acids. A large sample of the bakery mix and self-rising flour is used to provide sufficient carbon dioxide to be detected by the Chittick apparatus.
