Process Description

1

Raw Material Preparation

Whole oats undergo cleaning, destoning, magnetic separation, dehulling, and controlled milling to produce a uniform oat flour suitable for efficient protein extraction.

2

Enzymatic Extraction

Specialized food-grade enzymes selectively release proteins while preserving beta-glucan and minimizing protein denaturation.

Advantages include:

  • High protein recovery
  • Excellent protein functionality
  • High beta-glucan retention
  • Mild processing conditions
  • Consistent batch quality
3

Centrifugal Separation

Advanced decanter centrifuges separate:

  • Protein-rich extract
  • Oat starch
  • Fiber-rich fraction

This enables maximum utilization of every component of the oat kernel.

4

Membrane Filtration

Ultrafiltration and diafiltration systems purify proteins while removing low-molecular-weight impurities.

Benefits include:

  • Higher protein purity
  • Lower water consumption
  • Improved process efficiency
  • Excellent product consistency
5

Vacuum Concentration

The purified protein stream is gently concentrated under vacuum to preserve functional and nutritional properties before spray drying.

6

Spray Drying

Advanced spray drying technology produces premium free-flowing oat protein powder with:

  • Excellent dispersibility
  • High solubility
  • Low moisture
  • Neutral taste
  • Long shelf life
7

Quality Standardization

Each production batch undergoes comprehensive testing for:

  • Protein Content
  • Beta-Glucan Content
  • Moisture
  • Solubility
  • Particle Size Distribution
  • Bulk Density
  • Heavy Metals
  • Microbial Load
  • Amino Acid Profile
  • Functional Properties
