Butter (Unsalted) vs. Canola Oil (Refined Rapeseed)
Comparing 2 standards across 9 specifications. 8 key differences identified.
Unsalted dairy butter is an emulsion of water droplets in milkfat (minimum 80% butterfat, ~16–18% water, ~1–2% milk solids). Per 100g, it provides 717 kcal, 81.1g fat (51.4g saturated), and a low smoke point of 150°C (302°F).
Canola oil is refined oil extracted from low-erucic acid rapeseed (Brassica napus). Per 100g, it delivers 884 kcal, 63.3% monounsaturated fat, 28.1% PUFA (including 9.1% alpha-linolenic omega-3), 7.1% saturated fat, and a smoke point of 204°C (400°F).
