What is the primary cooking oil used in most Panda Express fryers?

The primary cooking oil used in most Panda Express fryers is vegetable oil. This choice is correct because vegetable oil has a high smoke point, which makes it ideal for frying a variety of foods while maintaining flavor and ensuring that the food is cooked evenly. Additionally, vegetable oil is often a blend of different oils, allowing for versatility in taste and frying performance.

While other oils like olive oil and coconut oil have their own unique properties, they are generally not used in large-scale fast food frying due to lower smoke points or higher costs. Canola oil is also a suitable option for frying, but vegetable oil is more commonly utilized in the industry, particularly in fast food chains like Panda Express, for its cost-effectiveness and cooking characteristics.
