The main by-products of corn starch are protein powder and corn oil. The primary processed products of corn mainly include: corn starch (70%), corn protein powder (5.5%), corn fiber feed (2 1.3%) and corn oil (3.2%).
The main by-product of corn alcohol is DDGS, that is, the drying of distiller's grains. DDGS is a very good feed for protein.
At present, both corn alcohol and corn starch are in the stage of price increase, mainly due to the price increase of corn raw materials, but the market demand is not very strong.
