What Is ExPress® Soy Meal and Why Is It Different?
We’ve explored how high-shear dry extrusion (HSDE) works and why it offers nutritional advantages over traditional soybean processing methods. But extrusion is only one part of the equation. When HSDE is paired with mechanical oil extraction, it creates a unique soybean meal known as ExPress® soy meal. Unlike conventional solvent-extracted soybean meal, ExPress® soy meal retains valuable residual oil while delivering highly digestible protein, making it an ideal ingredient for a variety of livestock and poultry diets.
Let’s answer the most common questions about what makes ExPress® soy meal different.
What Is ExPress® Soy Meal?
ExPress® soy meal is a mechanically extracted soybean meal produced using Insta-Pro International’s patented ExPress® process. The system combines high-shear dry extrusion with a mechanical oil press to process whole soybeans without the use of chemical solvents.
During extrusion, soybeans are rapidly heated through friction and shear, which deactivates anti-nutritional factors and prepares the beans for efficient oil extraction. The extruded soy then enters an oil press, where a portion of the oil is mechanically removed.
The result is a premium soybean meal that retains approximately 6–8% residual oil, providing both a high-quality protein source and additional energy for livestock diets.
How Is ExPress® Soy Meal Different from Solvent-Extracted Soybean Meal?
The primary difference lies in how the oil is removed.
Conventional soybean meals are typically produced using hexane solvent extraction, which removes nearly all of the soybean oil. While this creates a high-protein meal, much of the soybean’s natural energy is extracted along with the oil.
ExPress® soy meal uses only mechanical processing, eliminating the need for chemical solvents while preserving a portion of the soybean’s natural oil.
Key differences include:
- Produced without chemical solvent extraction.
- Contains approximately 6–8% residual oil.
- Provides both protein and energy in a single ingredient.
- Maintains excellent amino acid digestibility through proper processing.
- Supports a more sustainable, solvent-free processing system.
Why Does Residual Oil Matter?
Residual oil is one of the greatest advantages of ExPress® soy meal.
Because the meal naturally contains more oil than conventional soybean meals, it provides additional metabolizable energy to the diet. This can reduce the need for supplemental fats or oils while improving ration flexibility.
Higher dietary energy can help support:
- Improved feed efficiency.
- Better animal performance.
- More economical feed formulations.
- Greater flexibility for nutritionists.
Instead of purchasing protein and energy separately, ExPress® soy meal delivers both in one ingredient.
Which Animal Species Benefit Most from ExPress® Soy Meal?
ExPress® soy meal has been successfully incorporated into diets for numerous species, including:
Poultry
Broilers benefit from highly digestible amino acids and additional dietary energy. Research has shown improvements in body weight, feed conversion, and overall nutrient utilization when properly processed soybean products are included in poultry diets.

Swine
Growing and finishing pigs require highly digestible protein to maximize lean tissue growth. The combination of quality protein and residual oil supports efficient growth and feed utilization. Learn more here.
Dairy Cattle
High-shear dry extrusion modifies soybean protein, allowing a greater portion to bypass rumen degradation before being digested in the small intestine. Combined with the residual oil, ExPress® soy meal supplies both bypass protein and energy that support milk production and overall herd performance. Learn more here.
Does Mechanical Processing Affect Protein Quality?
Yes, but in a positive way when processing is properly controlled.
The combination of high-shear dry extrusion and mechanical oil extraction rapidly deactivates anti-nutritional factors without prolonged heat exposure that can damage amino acids.
Proper processing helps:
- Preserve lysine and other heat-sensitive amino acids.
- Improve protein digestibility.
- Increase nutrient availability.
- Produce a more consistent ingredient.
The result is a soybean meal that delivers both nutritional quality and processing consistency.
Is ExPress® Soy Meal More Sustainable?
Mechanical processing offers several sustainability advantages.
Because ExPress® soy meal is produced without chemical solvent extraction, processors eliminate the need for hexane during oil removal. The ExPress® process also simplifies processing while producing two valuable products from every soybean: premium soybean meal and mechanically extracted soybean oil.
In addition, retaining residual oil in the meal allows processors to capture more nutritional value within the feed ingredient itself.
Why Do Nutritionists Choose ExPress® Soy Meal?
Nutritionists look beyond crude protein—they evaluate digestibility, energy contribution, consistency, and animal performance.
ExPress® soy meal offers several formulation advantages:
- High-quality, digestible protein.
- Additional dietary energy from residual oil.
- Consistent processing quality.
- Reduced reliance on supplemental fat sources.
- Flexibility across multiple livestock species.
These characteristics make ExPress® soy meal a valuable ingredient for feed manufacturers seeking to maximize both nutritional value and economic return.
Key Takeaway
By delivering highly digestible protein and additional energy in a single ingredient, ExPress® soy meal helps nutritionists formulate efficient diets while providing processors with a sustainable, solvent-free alternative to conventional soybean meal.
