Corn Wet Milling ByProducts

The corn wet-milling process is more complex than either of the dry-milling processes. Large plants are necessary for efficiency of production. Dry-milling ethanol plants may use 30,000 to 50,000 bushels of corn per day, whereas wet-milling plants grind 150,000 to over 500,000 bushels per day. The wet-milling process produces alcohol and several human food products including sweeteners and corn oil. In the first step, corn is steeped in weak acid and then milled (ground). After grinding, the kernel is separated into four parts the germ, the starch, the bran (hull), and the gluten meal (protein). The oil is extracted from the germ. The starch is used for human consumption or ethanol production. The primary by-product is corn gluten feed, which contains the bran, steep liquor, and germ meal. This product is 16 24% protein and 40 50% fiber. The corn fiber is highly digestible by ruminants, probably even more rapidly digested than soyhull fiber.[8]

The majority (70 75%) of dry corn-gluten feed is shipped to Europe.[6] In the future, the amount produced will probably increase and the amount exported will probably decrease, making more gluten feed available for feeding in the United States. The practice of feeding wet corn-gluten feed to beef-feedlot cattle or dairy cows has been widely accepted.[7] The wet gluten feed has 100

110% the feeding value of dry rolled corn in beef-cattle feedlot diets when fed as 20 40% of the diet dry matter.[6]

Why Gluten Free

What Is The Gluten Free Diet And What You Need To Know Before You Try It. You may have heard the term gluten free, and you may even have a general idea as to what it means to eat a gluten free diet. Most people believe this type of diet is a curse for those who simply cannot tolerate the protein known as gluten, as they will never be able to eat any food that contains wheat, rye, barley, malts, or triticale.
