Why is storing wheat berries whole preferable to storing them as flour for very long-term reserves?
Answer
The protective bran layer shields the germ and prevents early rancidity.
When stored whole, the bran layer of the grain protects the germ and kernel, significantly delaying rancidity compared to milled flour where the fats are more exposed.
