A gluten-free pasta was prepared adding chia at rice flour for testing the thickening and nutritional properties of this specie. Chemical analysis showed chia is a source of protein (19.52% and 15.81%, seeds and mucilage respectively), insoluble/soluble dietary fiber ratio (4.3 and 1.79 seeds and mucilage respectively), fat and ash content. The total phenolic acids content ranged from 734.5 Î¼g/g to 923.9 Î¼g/g for seeds and mucilage respectively. Chia was a good thickening agent and, improved the nutritional profile of enriched samples compared to CGF. After cooking TPAs increased in all samples, ranging from 5.3% in DW to 52.8% in CM5. The addition of chia seeds also increased the slowly digestible starch fraction of rice flour, commonly known to have a high glycemic index. Results suggest that chia should be added as thickening agent in the formulation of GF pasta for conferring healthier characteristics.
