Rheological and textural properties of yogurts enriched with Jerusalem artichoke flour

Abstract

Rheological and textural properties of whole milk yogurt enriched with the flour from tubers of two Jerusalem artichoke cultivars were investigated. They were compared with the properties of yogurts enriched with the extracts containing fructooligosaccharides and other carbohydrates isolated by different methods from tuber flour. Chemical analysis of extracts was also performed. All yogurts enriched with tuber flour or other carbohydrates exhibited viscoelastic behaviour.
