Walk into any traditional Indian village and you will hear the rhythmic creak of the wooden Kolhu or Ghani. For millennia, Indian kitchens extracted edible oils by crushing seeds beneath stone and wood pestles at ambient temperatures under 45°C.
### The Refined Oil Industrial Reality
Modern refined oils are subjected to:
- Petroleum-based solvents (Hexane) for chemical extraction.
- De-gumming using phosphoric acid.
- Deodorization at extreme heats exceeding 230°C, transforming natural cis-fatty acids into harmful trans-fats and free radicals.
### The Cold-Pressed Advantage
In contrast, NIVANA wooden cold-pressed mustard, sesame, and groundnut oils are single-pressed without heat or chemicals. They retain their natural tocopherols (Vitamin E), polyphenols, and essential fatty acids. Use cold-pressed sesame oil for daily Ayurvedic cooking, and yellow mustard oil for rich immunity and distinct pungency.
