HOOK

Soybeans are one of the world's most valuable agricultural commodities, serving as a major source of protein, edible oil, and industrial raw materials. Soybean processing converts harvested soybeans into a wide range of products used in food, animal nutrition, biofuels, and numerous industrial applications.

HISTORY / OVERVIEW

Soybean processing involves a series of mechanical, thermal, and chemical operations designed to maximize the value of each soybean. Modern processing facilities are highly automated, enabling efficient production while maintaining product quality and food safety.

The primary outputs include soybean oil, soybean meal, soy protein ingredients, and lecithin, with virtually every part of the soybean utilized.

MAJOR PROCESSING STEPS

1. Cleaning

• Removal of stones, dust, metals, and other foreign materials

• Grading and quality inspection

2. Conditioning and Dehulling

• Moisture adjustment

• Heating

• Hull removal to improve processing efficiency

3. Cracking and Flaking

• Breaking soybeans into smaller pieces

• Rolling into thin flakes to improve oil extraction

4. Oil Extraction

• Mechanical pressing

• Solvent extraction (commonly using food-grade hexane in industrial facilities)

• Oil recovery and solvent removal

5. Oil Refining

• Degumming

• Neutralization

• Bleaching

• Deodorization

6. Meal Processing

• Toasting

• Drying

• Grinding

• Cooling

• Packaging
