The development of a natural dietary supplement containing corn roots could provide the means to improve the restrictive diet of phenylketonuria (<jats:styled-content style=\"fixed-case\">PKU<\/jats:styled-content>) patients by increasing their tolerance to dietary phenylalanine (Phe). Therefore this research was undertaken to explore the sensory characteristics of roots of four corn cultivars as well as to develop and evaluate food products (cereal bar, beverage, jam\u2010like spread) to which roots had been added.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Sensory profiles of corn roots were investigated using ten trained judges. Roots of Japanese Striped corn seedlings were more bitter, pungent and astringent than those of white and yellow cultivars, while roots from the Blue Jade cultivar had a more pronounced earthy\/mushroom aroma. Consumer research using 24 untrained panelists provided hedonic (degree\u2010of\u2010liking) assessments for products with and without roots (controls). The former had lower mean scores than the controls; however, the cereal bar had scores above 5 on the nine\u2010point scale for all hedonic assessments compared with the other treated
