What is vacuum frying (VF) in veggie chips processing?

Vacuum frying (VF) is a frying technique that uses a vacuum to fry food at lower temperatures than traditional frying methods. Compared with traditional frying (atmospheric conditions), vacuum frying reduced acrylamide formation in veggie chips dramatically by about 94%. Vacuum frying vegan snacks at 118°C produced fruit and vegetable-based snacks with low acrylamide content and desirable yellow golden color and texture attributes as compared to those fried in the traditional fryer.
