The effects of different hydrocolloids on chemical composition and cooking quality of spaghetti based on
maize and oat flours were investigated. Rheological and texture properties of the gluten-free dough were
also assessed. Amount of 2% of gellan gum, carboxymethylcellulose, pectin, agar, egg protein powder,
tapioca starch, guar seed flour and chitosan were separately added to the formulation. The samples
enriched with hydrocolloids generally showed a different rheological behaviour compared with the control
samples. As regards chemical composition, spaghetti with chitosan showed a value of insoluble dietary
fibres (8.0%) higher than the control ones (3.9%). Moreover, results highlighted that most hydrocolloids
improved cooking quality and texture properties of spaghetti (adhesiveness, cooking loss, hardness), thus
supporting their application in gluten-free pasta.
