Description
Vacuum frying removes moisture at reduced pressure, allowing lower frying temperatures that limit oil absorption and preserve heat‑sensitive compounds.
Technical
By lowering the ambient pressure, the boiling point of water is reduced to about 70–80 °C, enabling moisture removal at temperatures well below conventional frying. This reduces the extent of the Maillard reaction and limits acrylamide precursor formation, while also preserving thermolabile nutrients such as vitamin C and carotenoids. The reduced temperature also minimizes oil oxidation and the formation of harmful lipid oxidation products.
