Soybean meal

Soybean meal specs primarily focus on protein, moisture, fat, and fiber content, with typical values for 48% protein meal including around 48% crude protein, 12% maximum moisture, 1.5% maximum fat, and 3.5% maximum fiber. Other important specifications can include ash content, urease activity, heavy metal limits, and an absence of mold or harmful contaminants, with specific requirements varying by region and intended use, notes Soytex. 

Key Specifications

The quality of soybean meal is determined by its nutritional profile and safety characteristics: 

• Crude Protein: A high protein content is essential, with common specifications for high-protein meal ranging from 46% to 50%. 
• 
  

Other Important Parameters

Beyond the core nutritional components, other factors ensure quality and safety:

• Sand/Silica: Limits on sand and silica prevent contamination and ensure the purity of the feed. 

Moisture: High moisture content can lead to spoilage and degradation, so it is typically limited to a maximum of 12%. 

Crude Fat: The oil is extracted during processing, and specifications often set a low maximum for fat, such as 1.5%. 

Fiber: Crude fiber content is another critical metric, with limits generally around 3.5% to 6% depending on the type of meal. 

Ash: The total ash content, which indicates mineral content, is also a consideration, often specified around 7%. 

Urease Activity: This measures the enzyme's activity, which is important for the meal's digestibility and is often specified with a maximum value, according to Chezlynne. 

Contaminants: Specifications will also include limits for heavy metals like lead, cadmium, and arsenic, as well as for mycotoxins such as aflatoxin. 

Microbiological Safety: The presence of pathogens like Salmonella and E. coli is unacceptable, notes Chezlynne. 

Physical Characteristics: The meal should have a fresh, toasted, and nutty smell, and be free of foreign odors or visible signs of mold or damage
