Food scientists categorize cooking fats across four distinct production methods. Traditional dairy, hydrogenated plant oils, precision-fermented lipids, and thermochemically assembled fats each carry different thermodynamic footprints and regulatory definitions.
| Category | Primary Feedstocks | Lipid Architecture | Est. Carbon Footprint (kg CO2e/kg) |
|---|---|---|---|
| Conventional Butter | Bovine milk, water, salt | Bovine milk fat (400+ distinct fatty acids) | 9.0, 12.5 |
| Plant-Based Margarine | Palm, canola, sunflower oils | Fractionated or hydrogenated plant triglycerides | 1.5, 3.5 |
| Precision-Fermented Dairy | Sugar/dextrose feed, engineered yeast | Yeast-expressed bovine lipids and proteins | 2.0, 4.0 |
| Carbon-Synthesized Fat | Captured CO2, green hydrogen, heat | Thermochemically tailored identical triglycerides | 0.8, 1.8 |
