The Science of Wood Cold-Pressed Oils: Preserving Vital Nutrients
DA

High-heat solvent extraction destroys delicate fats. Learn why wooden churners (Ghani) maintain complete enzymatic integrity.
Modern refined cooking oils are extracted using chemical solvents like petroleum-derived hexane and heated past 200°C before undergoing chemical bleaching and deodorization. This industrial process strips natural tocopherols (Vitamin E) and generates harmful trans-fatty residues.
The Traditional Vaagai Wood Ghani
By contrast, traditional wood-pressing (Vagai tree Ghani) crushes sun-dried seeds slowly without external heating, keeping temperatures strictly below 45°C.
Key Nutritional Differences:
- Unbroken Tocopherol Matrix: Natural Vitamin E compounds protect against cellular oxidative stress.
- Natural Plant Sterols (Phytosterols): Compounds that help maintain healthy lipid profiles by competing with dietary cholesterol for absorption.
- Authentic Aroma & Flavor: Retains the rich, nutty notes of unadulterated sesame, groundnut, and coconut seeds.
- Zero Chemical Residues: No caustic soda, acid washing, or bleaching earth involved at any stage.
