Abstract
The present invention discloses a method for drying berries, which first uses a combined treatment of pulsed electric field and plasma on the berries, and then dries the berries after the combined treatment. This method can change the microstructure inside the berries, including increasing the surface roughness, increasing hydrophilicity, forming surface electroporation holes and internal membrane perforations, thereby promoting water migration, improving the drying efficiency and quality of the berries. This method also has the advantages of no residue and simple operation. By using a combined treatment of pulsed electric field and plasma to treat the berries, it can inactivate the microorganisms on the berries, degrade the biotoxins produced by the microorganisms, reduce the loss of nutrients caused by drying, and at the same time can inactivate oxidase and reduce the oxidation of antioxidant substances during the drying process.
