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.
For every teaspoon of baking powder called for in your recipe, youâll need just 1/4 teaspoon of soda to replace its leavening action. Youâll also need to furnish the necessary acidity, adding either 1/2 teaspoon of cream of tartar or a cup of buttermilk or soured milk to the recipe in place of sweet milk. Alternatively, add a tablespoon of lemon juice per cup of milk.
