Acidulants: Leavening acids
Acidulants activate CO2 development of the baking salts and are used to adjust the pH of the final products. It is possible to get a faster or slower formation of CO2 in the oven using different acidulants.
In this respect the pH of raw materials like corn, invert syrup, liquid caramel colour and fruits can have a relatively low pH value and then there will be a reaction that could result in some premature CO2 development when they come in contact with the leavening agents. Understanding therefore ingredients’ acidity is important for controlling leavening action: a reaction will take place when raw materials with a low pH come into contact with the leavening agents. When this reaction is kept at a minimum and the dough always prepared under the same conditions there will be no differences in the final product.
