Two enzymes, lactase-phlorizin hydrolase (LPH) and sucrase isomaltase (SI), are anchored to the mucosal surface of the small intestine where the soluble sugars in the lumen are hydrolyzed to free glucose, galactose, and fructose, which are absorbed rapidly from the lumen.
How to substitute baking soda for baking powder. You can substitute baking soda for baking powder, if you increase the amount of acidic ingredients in the recipe to offset the baking soda. Youâll also need much less baking soda as it is 3 times as powerful as baking powder. Youâll need about a teaspoon of vinegar or lemon juice for every 1/2 teaspoon of baking soda.
So I usually double the baking powder the wheat based recipe calls for when cooking gluten free. If a recipe calls for baking soda that is not complimented with vinegar in the same recipe then I change it to baking powder. For example, some chocolate chip cookie recipes call for both baking soda and baking powder.
