The main reason is they come from two different sunflowers, bred for two different jobs — The large, striped seeds we eat are confectionery seeds.
They grow them for size and taste-not oil.
The yield is lower.
Each seed must be handled with care-to keep the kernel whole for the bag. They are cleaned, sorted by size, roasted, and inspected-This takes labor and special machines, though.
The oil comes from a different flower-The seeds are small and black, bred for high oil content, a crop for crushing. They are harvested in bulk and smashed by the ton, the oil is pressed out.
Then stripped.
With solvents to get every drop.
The leftover meal.
Now becomes-animal-feed — One is handled like a finished product.
The other is a raw material-broken down for pure yield.
