High pressure processing (HPP) is one of the emerging technologies in food processing and preservation which offers the opportunity of producing food of high quality, greater safety and increased shelf-life. The purpose of this study was to determine the impact of HPP parameters and storage time on the range of changes in total saccharides and reducing saccharides contents in the pressure processed carrot juices. During the reported storage period observed decrease of total saccharides content was associated with an increase of reducing saccharides content. The extent of noticed changes of analyzed factors depended of compression parameters and storage time of the researched carrot juices.
