In this context, most recent research in this area is addressing and attempting to improve the nutritional value and sensory characteristics of gluten-free (GF) food products and to enhance their technological properties. Here, amaranth flour was studied as a potential healthy ingredient for the development of an innovative GF flat bread. Starting from two different basic formulations (rice flour:corn starch and rice flour:tapioca starch, 50:50), the impact of partially replacing rice flour (6%) and starch (6%) with amaranth on the nutritional characteristics, polyphenol composition, textural, and sensory properties of the resulting GF flat breads was explored. The substitution with amaranth led to detrimental effects on the doughs\u2019 viscometric properties, especially in the case of tapioca starch, but significantly improved the doughs\u2019 textural properties. All the amaranth-enriched flat breads showed a better color and a significant increase in all polyphenols fractions but lower antioxidant activity. During bread storage for three days, a detrimental effect on both starch retrogradation, toughness, and extensibility properties were observed, especially when tapioca starch was used. Check-all-that-apply (CATA) sensory test results showed that the incorporation of amaranth increased yeast odor and yeast flavor perception and decreased the softness in mouth-only in tapioca-based samples. A better compromise among technological, nutritional, and sensory properties was achieved when amaranth flour was added to the basic rice and corn formulation.<\/jats:p>","DOI":"10.3390\/foods10050920","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T13:59:14Z","timestamp":1619099954000},"page":"920","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Technological, Nutritional and Sensory Properties of an Innovative Gluten-Free Double-Layered Flat Bread Enriched with Amaranth Flour"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0309-5936","authenticated-orcid":false,"given":"Antonio","family":"Piga","sequence":"first","affiliation":[{"name":"Dipartimento di Agraria, Universit\u00e0 degli Studi di Sassari, Viale Italia 39\/A, 07100 Sassari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3976-924X","authenticated-orcid":false,"given":"Paola","family":"Conte","sequence":"additional","affiliation":[{"name":"Dipartimento di Agraria, Universit\u00e0 degli Studi di Sassari, Viale Italia 39\/A, 07100 Sassari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simonetta","family":"Fois","sequence":"additional","affiliation":[{"name":"Porto Conte Ricerche Srl, Localit\u00e0 Tramariglio, 07041 Alghero, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pasquale","family":"Catzeddu","sequence":"additional","affiliation":[{"name":"Porto Conte Ricerche Srl, Localit\u00e0 Tramariglio, 07041 Alghero, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7677-8535","authenticated-orcid":false,"given":"Alessandra","family":"Del Caro","sequence":"additional","affiliation":[{"name":"Dipartimento di Agraria, Universit\u00e0 degli Studi di Sassari, Viale Italia 39\/A, 07100 Sassari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna Maria","family":"Sanguinetti","sequence":"additional","affiliation":[{"name":"Dipartimento di Agraria, Universit\u00e0 degli Studi di Sassari, Viale Italia 39\/A, 07100 Sassari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6666-9079","authenticated-orcid":false,"given":"Costantino","family":"Fadda","sequence":"additional","affiliation":[{"name":"Dipartimento di Agraria, Universit\u00e0 degli Studi di Sassari, Viale Italia 39\/A, 07100 Sassari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sapone, A., Bai, J.C., Ciacci, C., Dolinsek, J., Green, P.H.R., Hadjivassiliou, M., Kaukinen, K., Rostami, K., Sanders, D.S., and Schumann, M.
