Minor products obtained during corn processing are:
- dry corn gluten
- dry corn kernel
- raw gluten fodder
- raw squash
- grain mixtures
Corn gluten
Corn gluten is a loose powder from light-yellow to dark-grey colour with specific pleasant smell, stable during storage. Corn gluten contains about 60 % of raw protein. Protein of corn gluten contains a lot of essential amino acids and is the best source of methionine, beta-carothene (pro-vitamin A), xanthophyll, threonine, tryptophan, calcium, phosphorous, sodium, and rich complex of fat and water soluble vitamins Å, Â1, Â2, Â3, Â4, Â5, Â6.
Corn kernel
Corn kernel is extracted from corn grain by “wet method”. A kernel that represents about 8 – 14 % of corn grain weight contains 84 – 86 % of fat present in corn. A kernel is a raw material for production of corn oil, and one of the components of fodders for animals.
Raw gluten fodder
Minor products obtained during corn processing – squash and boiled extract – are used for extraction of raw gluten fodder. Analysis of components content shows that their use as fodders for animal breeding is perspective, because they are a source of essential amino acids, microelements, and carbohydrates. Besides that gluten fodder by energy value is close to Gramineae grain and has ÊÅ 1.15 kg, ÎÝ 11.9 ÌJ.
Raw squash
Squash is formed in the process of corn processing and is represented by particles of grain cover. Squash is composed from fiber which makes fodder porous and increase its digestibility.
Grain mixtures
Grain mixture is a waste of corn grain separation. It consists of grinded corn grain and partially (1 – 2 %) of particles of ear shanks that significantly increase its digestibility and has positive influence on animals digestion.
