I’ve found that bulk powdered milk and potato flakes can taste a bit funky after a couple of years in the original packaging. I now prefer smaller serving-sized packaging as opposed to bulk-sized storage.

It’ll taste better after SHTF.

Texas is humid and if a large box of instant milk soaked up some of that humidity the box would turn into a brick, so I buy the boxes that have quart amount packages inside. For my long life milk, I got it hermetically sealed in cans from Walton.

So, I have grocery store food for the short term, and Walton food for the long term.

I keep vanilla to make the milk taste good and saffron to flavor a variety of things.

lemon pepper salt also is one my favorites.

You might look into butylated hydroxytoluene, or BHA, butylated hydroxyanisole, or BHT, tert-butylhydroquinone and propyl gallate as preservatives to prevent spoilage.
