Abstract:
The present invention relates to a method of lowering and controlling the content of reducing sugars in a potato raw material without affecting the cell wall or starch structure, said method comprising the steps of suspending the potato raw material in an aqueous carrier and applying moderate electric field pulses having a field strength in the range of from 200 to 10,000 V/cm, or a moderate electric alternate current field having a field strength in the range of from 100 to 400 V/cm to the suspended potato raw material. The method can be applied in a process for producing potato chips, prior to a frying step. Furthermore, the invention relates to a device for carrying out the method of the invention.
Abstract:
A process for producing fried potato products having a low fat content, for instance, of less than 19 % by weight based on the weight of the potato product after frying and de-oiling, is provided which comprises the steps of providing potato slices, blanching the potato slices with a solution comprising divalent cations at a temperature of 50 °C or more, frying the potato slices, and de-oiling the fried potato slices, preferably by applying superheated steam. Furthermore, a fried potato product obtainable by said process is disclosed.
