Abstract
Microwaves processing (UHF) is a method of heat treatment of raw materials to preserve a food product quality. The degree of inhibition by microwave blanching of oxidationreduction processes leading to browning of potato tissues when preparing for quick freezing was studied. To control the effectiveness of microwave processing as an antiseptic factor during preparation and storage of fruit and vegetable raw materials, an experimental method for definition of the activity of oxydoreductases at cut potato blanching was tested. This process limits the changes of raw materials as well as those of finished produce of quick freezing when storing. The regimes of microwave processing reducing unfavorable changes of the product tissues (browning, etc.) have been defined. The thermal treatment of cut potatoes using microwave energy was compared with traditional water blanching.
