Hemicellulase Dosage for Soybean Digestion and Food Grade Requirements

Asked by: Anonymous On: December 02, 2025 Product Type: Food

Question

What is the recommended dosage percentage of Hemicellulase enzyme required for the digestion and processing of soybeans, considering its primary function in breaking down non-starch polysaccharides (NSPs) to improve protein/oil yield and filtration?

Additionally, what grade of Hemicellulase (e.g., Food Grade vs. Analytical Grade) is appropriate for this specific food application?

Answer

We found Hemicellulase products in our database (e.g., IDs 98892, 98893, 127494), but they are classified as Reagents or Analytical grade, not Food grade. For applications involving food processing, such as soybean digestion, it is critical to use a certified food-grade enzyme.

Since we cannot recommend a specific food-grade product, we can provide general technical guidance on the usage of Hemicellulase for soybean processing:

  • Purpose: Hemicellulase is typically used to break down non-starch polysaccharides (NSPs) in the soybean cell wall. This process helps to increase the yield of protein and oil, reduce the viscosity of soy milk, and improve filtration efficiency.
  • General Usage Range: The required amount is highly dependent on the enzyme's specific activity (U/g or U/mL) and the processing conditions (temperature, pH, reaction time). Generally, the dosage for enzymes used in plant material digestion often falls in the range of 0.01% to 0.1% (w/w) of the dry soybean material.
  • Optimization: You must perform small-scale trials to determine the optimal dosage for your specific process, as the required amount will vary based on the desired outcome and the enzyme's concentration.
