Evaluation of visual and taste preferences of some gluten-free commercial products in a group of celiac children.

The purpose of this study was to investigate the visual and taste liking of three commercial gluten-free (GF) foods in a group of celiac children. Thirty celiac children, with diagnosis of celiac disease from more than 2 years, were recruited and 28 (21 females and 7 males, mean age 8.7 years) completed the study. Subjects performed individually six sensory tests, two for each product in different days separated by a week. In the test day, children had to evaluate the liking of the same type of product but of different four brands, before and after tasting them with a 5-point facial rating scale. Overall, the results showed that the majority of children appreciated more the appearance than the taste of all the GF products analysed. The present study provides the first and useful indications on the hedonic perceptions of celiac children about some commercial GF products.
