What is a smoke point?
The smoke point is the temperature at which an oil starts to break down and produce visible smoke. It affects flavor and safety when cooking.
Why does refinement affect the smoke point?
Refined oils have impurities and free fatty acids removed, which makes them more stable at high temperatures, raising their smoke point.
How accurate is this calculator?
It provides a rough estimate based on typical ranges. Actual smoke points vary by oil type and specific processing, so use it as a guide.

Smoke point estimate
This linear model approximates how refinement increases smoke point and impurities decrease it.
实际应用场景
此计算在日常生活中的应用。
Choosing the right oil for frying
Pick an oil with a smoke point above your cooking temperature to avoid burning and off-flavors.
Example: For deep frying at 180°C, choose an oil with a smoke point above 200°C.
Comparing oils
Quickly compare how different refinement levels affect the smoke point of similar oils.
Example: Extra virgin olive oil (unrefined) vs. refined olive oil.
Cooking with reused oil
Estimate how impurities from food particles lower the smoke point of oil you reuse.
Example: If your oil has 2% impurities, its smoke point drops by 20°C.

Tips
- Use refined oils for high-heat cooking like searing and frying.
- Store oils in a cool, dark place to slow degradation.
- Avoid heating oil past its smoke point; it can produce harmful compounds.
- If oil smokes, lower the heat and consider replacing it.
Common Mistakes to Avoid
- Using unrefined oil for deep frying, which burns easily.
- Ignoring that impurities from food lower the smoke point.
- Assuming all oils of the same type have the same smoke point.
假设与限制
- Use the stated inputs and units.
- Results are estimates for planning and education.
- Check measurements and source data before making an important decision.
