Standard Soybean Definitions

Soybean Cake or Soybean Chips is the product after most of the oil is extracted from whole soybeans by pressure or solvents from soybeans. A name descriptive of the process of manufacture, such as “expeller," “hydraulic” or “solvent extracted” is used in the brand name. It shall be designed and sold according to its protein content.

Soybean Meal

is ground soybean cake, ground soybean chips, or ground soybean flakes. A name descriptive of the process of manufacture, such as “expeller,” “hydraulic” or “solvent extracted” is used in the brand name. It shall be designed and sold according to its protein content.

Soybean Mill Feed

is the byproduct resulting from the manufacture of soybean flour or grits and is composed of soybean hulls and offal from the tail of the mill. A typical analysis is 13% crude protein, 32% crude fiber and 13% moisture.

Soybean Meal Info Center - Mill Run

Soybean Mill Run

is the byproduct resulting from the manufacture of dehulled soybean meal and is composed of soybean hulls and such bean meats that adhere to the hull in normal milling operations. A typical analysis is 11% crude protein, 35% crude fiber and 13% moisture.

Soybean_hulls

Soybean Hulls

are a byproduct of soybean processing consisting primarily of the outer covering of the soybeans or seed coat. A typical analysis is 10-12% crude protein, 36-40% crude fiber and 9-13% moisture.

Standard Soybean Composition Specifications

Soybean Flakes and 44% Protein Soybean Meal are produced by cracking, heating and flaking soybeans and reducing the oil content of the conditioned product by the use of hexane or homologous hydrocarbon solvents. The extracted flakes are cooked and marketed as such or ground into meal. Standard specifications are as follows.

Soybean Flakes and High Protein or Solvent Extracted Soybean Meal are produced by cracking, heating and flaking dehulled soybeans and reducing the oil content of the conditioned flakes by the use of hexane or homologous hydrocarbon solvents. The extracted flakes are cooked and marketed as such or ground into meal. Standard specifications are as follows.

Soybean Meal Composition Data

Soybean meal is a fairly consistent feed ingredient; therefore these average values should be of value in programming feed formulation computers. Some of the major feed formulators will analyze each lot of soybean meal for key nutrients. This provides accurate information on nutrient levels but adds to the cost of feed formulation. Many feed formulators will use a combination of average table values for some nutrients, selective sourcing their soybean meal and upgrading their ingredient database as new values are developed.
