Why Soybean Oil Must Be Refined?

Freshly pressed soyabean oil contains three harmful components:
1. Phospholipids - Generate smoke & foam when heated;
2. Free Fatty Acids (FFA) - Cause rancidity and "off-flavors";
3. Micro-impurities - Pigments/gums/metal particles affecting health.

Refining ≠ Nutrient Loss
Core nutrients (unsaturated fats, vitamin E) become more stable:
✅ Vacuum deodorization preserves antioxidants;
✅ Removing phospholipids extends shelf life.

Risks of Unrefined Crude Oil?

• Microbial growth from moisture-attracting phospholipids;
• Digestive stress from excessive FFAs.
