Example Calculations

1Deep Frying with Peanut Oil

Inputs

Cooking MethodDeep Frying (350-400°F)
OilPeanut Oil (450°F)

Result

Safety RatingGood
Safety Margin+50°F
Smoke Point450°F

Peanut oil smoke point (450°F) minus deep frying max (400°F) = +50°F safety margin, rated Good.

2Stir-Fry with Extra Virgin Olive Oil

Inputs

Cooking MethodStir-Fry (400-500°F)
OilExtra Virgin Olive Oil (375°F)

Result

Safety RatingUnsafe
Safety Margin-125°F
RecommendationUse avocado or peanut oil instead

EVOO smoke point (375°F) is below the stir-fry range (400-500°F), giving a -125°F margin. This is unsafe — the oil will smoke and break down.

Frequently Asked Questions

Q

What is a smoke point?

The smoke point is the temperature at which an oil begins to break down and produce visible smoke. When oil exceeds its smoke point, it releases harmful compounds, develops off-flavors, and loses nutritional value. Cooking below the smoke point is important for food safety and taste.

Q

Which oil has the highest smoke point?

Avocado oil (refined) has one of the highest smoke points at 520°F (271°C), making it excellent for high-heat cooking methods like grilling and searing. Other high smoke point oils include safflower oil (510°F), rice bran oil (490°F), and ghee (485°F).

Q

Is it safe to cook with olive oil?

Yes, refined (light) olive oil has a smoke point of 465°F, making it suitable for most cooking methods including frying. Extra virgin olive oil has a lower smoke point of 375°F, but recent research shows it remains stable at moderate cooking temperatures due to its high antioxidant content.

Q

What happens when oil goes past its smoke point?

When oil exceeds its smoke point, it begins to decompose. This produces acrolein and other harmful compounds, creates unpleasant bitter and burnt flavors, generates visible smoke and can trigger smoke alarms, and destroys beneficial fatty acids and antioxidants.

Q

What is the best oil for deep frying?

The best oils for deep frying (350-400°F) are peanut oil (450°F smoke point, classic flavor), canola oil (400°F, neutral and affordable), and sunflower oil (440°F, neutral). These oils have high smoke points, neutral flavors, and are cost-effective for the large quantities needed.
