Will dried buttermilk react with other ingredients in dry mix with oil, stored in fridge?
I would like to make a (dry) pancake mix in a large batch, and then store it in the fridge. I have done this before with no problem, and would now like to do the same thing, but add dried buttermilk. I was wondering if the dried buttermilk will store well with other ingredients, while stored in the fridge.
The other ingredients include oil. The full ingredients are:
4 cups King Arthur white whole wheat flour
1 cup King Arthur Unbleached All-Purpose Flour
3 1/2 cups old-fashioned or rolled oats
3 tablespoons sugar
3 tablespoons baking powder
1 tablespoon salt
1 tablespoon baking soda
1 cup vegetable oil

The baking soda and acid from the dried buttermilk should not react in any significant amount until you hydrate the mixture, so it should work. Remember, baking powder is acid and sodium bicarbonate in the same can, and there is little except acid and reactant; your mix will have a lot of buffer ingredients as well.
I would not add the oil to the dry mix though until you are ready to make the pancakes, along with the water.

No, it will not react.Does powdered buttermilk need to be refrigerated?
If your powdered buttermilk is unopened, it can be kept at room temperature; however, once opened, it should be refrigerated to extend its life.How do you store dried buttermilk powder?
Yes you can pre-mix your dry ingredients in advance. You can mix the flour, sugar, baking powder, baking soda and salt. Store your mix in an dry airtight container. It's important the container will be airtight to prevent any moisture from getting in.Can you premix dry ingredients?
To activate it, all you need to do is add a liquid (which, by definition, a batter has to contain anyway). Being self-contained isn't baking powder's only trick. When you mix wet and dry ingredients, baking powder activates instantly, enlarging bubbles in the batter and making it rise.🔵 Truth About Buttermilk - What Is It? How To Substitute?

Answer 2
No, it will not react. There is a bit of theory behind it.
The reaction in batter is a reaction between a base and an acid. For this type of reaction, you need ions swimming freely in water. In dried substances, your ions are stuck to other ions to form molecules, or ion gitters, depending on the substance. They cannot react with anything, just like a pen with a cap cannot make a stain on your clothes if you keep it in your pocket.
For this reason, you can add the oil without a problem. Oil is a nonpolar liquid and it will not separate the ions from their molecules/ion gitters. There aren't many reactions which can happen in the oil.
From a food safety point of view, there are bacteria which can live under oil given the right conditions, so you cannot keep just anything under oil. Any fresh plants are dangerous. But your mixture looks safe. The dried oats should not pose a problem, as there is no moisture in them, same goes for the flour. Just make sure that you are indeed using oil - even the small amount of water in butter is enough to make butter/flour mixtures perishable.
