Which raising agent

Flour sold as self raising already includes baking powder, to make your own sieve 2 tsp Baking Powder and add into g of plain flour and mix well. Baking Powder is sometimes added to batter in place of, or to compliment egg and will aerate the flour and liquid blend. This alkaline powder, sometimes called baking soda, bicarb or NaHCO3 reacts with the acidic ingredients in a recipe. Combined with oven heat this creates small bubbles and a rise during cooking.

If used in excess it can impart a metallic taste. Often combined with yogurt, buttermilk, lemon juice, vinegar, or molasses to rise un-yeasted bread, soda bread and quick breads. Added to some cake recipes made with plain flour and an acidic ingredient such as apple sauce, citrus, cocoa, brown sugar or molasses that combines to generate bubbles and lift during cooking.

A batter made with Bicarbonate of Soda becomes light and crispy thanks to the many small gas bubbles it creates. French bakers add it their baguette recipes. Since chemical raising agents are alkaline, they react with acidic ingredients in baking mixtures, like milk, to produce carbon dioxide bubbles. Chemical raising agents are usually alkalis, and they work by reacting with acidic ingredients, like milk, to produce carbon dioxide.

Only once water or moisture is added can the acid-base reaction occur. This reaction is slow at first, but it accelerates when the dough is baked inside the oven. During this process, the introduction of heat does more than speed up the chemical reaction — it also causes the pockets of gas to expand, forming larger bubbles.

This means that while the dough grows in size, it becomes significantly less dense. Basically, the bigger the air bubbles, the lighter and fluffier the product. A cake, for example, has a lot of bubbles in it, which is what makes it less rigid than, say, bread. There are three main types of chemical raising agents used in baking.

Heat from the oven speeds up the chemical reactions in doughs or batters by causing air pockets to expand. BNF factsheet: Aerate. Skip to main content. Raising agents: chemical. Why do some recipes use chemical raising agents and how do they work?
