🌿 FFA Value Range (Edible Oils)
| Oil Type | Minimum FFA (%) | Maximum Acceptable FFA (%) | FSSAI Limit |
|---|---|---|---|
| Sesame Oil | ~0.05 | ≤ 4.5 | 4.5 |
| Coconut Oil | ~0.05 | ≤ 2.5 | 2.5 |
| Groundnut Oil | ~0.05 | ≤ 3 | 3 |
| Refined Oils | ~0.01 | ≤ 0.05 | 0.05 |
🧪 Note: These are typical values when the oil is fresh and properly filtered. The values can rise over time due to improper storage or exposure to air, light, and heat.
🔬 What is FFA?
FFA (Free Fatty Acid) measures the extent of hydrolysis in oils. High FFA levels indicate breakdown of triglycerides, often due to aging or poor storage.
⚠️ FFA & Rancidity
- Higher FFA = Higher chance of rancidity.
- Rancid oils taste and smell bad, and can be harmful to health.
- Fresh wood-pressed oils generally have low FFA when processed and stored correctly.
- Refined oils have extremely low FFA, but lose much of their nutrients during processing.
