Raising Agent, typically Baking Soda contains CO2 (Carbon DiOxide) in a powderform.
This powder when mixed into the dough will start to react with moisture and acidity in the mix and produce bubbles of CO2.
When heated up whilst baking, this gas expands and your product raises a little or a lot depending on little or much baking soda in the mix.
It hardly give any noticeable taste in finished product.
At most it might leave traces of some NaOH or Na2O.
The traces of residue after its function is finished is not poisionus in these quantities..

Raising agents introduce carbon dioxide gas into foods - by chemical reaction. They're intended to make pastries and bread food more palatable.
Function of raising agents in a muffin?

Raising agents are used in baking to introduce air or gas into a mixture, causing it to expand and rise during baking. This process creates a lighter, softer texture in baked goods such as cakes, muffins, and bread. The main principles behind raising agents are to create leavening, which helps dough or batter to rise and become fluffy.
Shortcrust pastry is classically made without raising agents - just plain flour, butter, salt and water.
The glutton starts to develop from the flour and the raising agents ( baking soda and/or baking powder) starts to work.
Carbon dioxide is produced by the raising agents in cakes.
You have to be sixteen years old to work at Raising Canes.
If it has any raising agents in it (including self raising flour), you should cook it immediately after mixing. If it does not, it should be ok in the fridge.
It makes the product light and fluffy and springy and airy.
