Agricultural and Biosystems Engineering
Soyhulls are a co-product of soybean processing. The soyhull is the seedcoat of the soybean (not the pod) and makes up approximately 8% of the soybean. When the soybeans are rolled or flaked, the soyhull pops loose from the meat of the seed. The soyhulls are very lightweight and once loose can easily be removed from the seed by air. The soyhulls are ground and blended back with the soybean meal to produce 44% meal, or they can be used as a feedstuff in various types of livestock and dry rations.
