What is vacuum frying?
Vacuum frying is a cooking process that utilizes low pressure to fry foods at lower temperatures than traditional frying methods. This technique helps retain more nutrients, color, and flavor in the food. By reducing the pressure in the frying chamber, the boiling point of oil decreases, allowing for frying at temperatures typically around 60-90°C (140-194°F). This results in a unique, crispy texture while preserving the original characteristics of the ingredients.
The main advantage of vacuum frying is that it minimizes the formation of harmful compounds that can occur during conventional frying. Traditionally fried foods can often absorb a significant amount of oil, leading to an unhealthy final product. On the other hand, vacuum frying allows for a much drier end product, which not only enhances the nutritional value but also results in a lighter snack that is appealing to many health-conscious consumers.
