Propriedades tecnológicas, nutricionais e sensoriais de biscoito tipo cookie sem glúten, desenvolvido com arroz de diferentes teores de amilose e feijãocaup

Abstract

The use of rice flour is a widely used alternative in gluten-free baking products, however the composition and characteristics of the products depends on the particularities of the flour used in its preparation. The objective of this study was to evaluate the effects of mixed rice flour with different levels of amylose and cowpea on technological, nutritional and sensory properties of cookie. The properties of flours, such as proximal composition, solubility and water absorption, water activity, soluble protein and protein digestibility were analyzed. Cookie quality parameters such as proximal composition, water activity, soluble protein, protein digestibility, thickness, diameter, dispersion factor, texture, color, amino acid profile and sensory analysis with the tests of preference, acceptance and intention of were evaluated. Cookies prepared with the formulation containing high (BRS Catiana) and medium amylose (EEA 406) rice flour had the lowest values of hardness, respectively, while those made with low amylose (Cateto) rice flour, presented greater fracture. Cookies made with rice flour with low amylose content (Cateto) were sensorially harder and darker. Cookies made with high amylose (BRS Catiana) rice flour showed lighter color, less hardness and higher preference. The odor and taste attributes do not present differences between the formulations.
