Extruded Quinoa Flour Applied for the Development of Gluten-Free Breads: a Technological, Sensory and Microstructural Approach.

Quinoa flour due to its nutritional and sensory characteristics could be used as an ingredient to improve the nutritional and technological properties of gluten-free bread. Furthermore, the application of hydrothermal processes such as extrusion can enhance their native properties. Hence, our objective was to evaluate how the incorporation of extruded quinoa flours (EQFs) affects the technological, sensory and nutritional quality of gluten-free bread.

Rice proteins - Gum arabic coacervates: Effect of pH and polysaccharide concentration in oil-in-water emulsion stability.

In the context of replacing animal proteins in food matrices, rice proteins (RP) become promised because they come from an abundant plant source, are hypoallergenic, and have high digestibility and nutritional value. However, commercial protein isolates obtained by spray drying have low solubility and poor functionality, especially in their isoelectric point. One way to modify these properties is through interaction with polysaccharides, such as gum arabic (GA).

Pea protein isolate-soluble soybean polysaccharides electrostatic assembly: effect of pH, biopolymer mass ratio and heat treatment.

Background: In past years, thousands of protein-polysaccharide complexes have been investigated to modify protein characteristics and functionality in food systems. However, the interaction between pea protein isolate (PPI) and soluble soybean polysaccharide (SSPS) has not been thoroughly characterized yet.

Results: In the present study, the phase behavior of PPI and SSPS mixtures was analyzed as a function of PPI:SSPS mixing ratio (1:1 to 1:0.

Combination of pH-shifting, ultrasound, and heat treatments to enhance solubility and emulsifying stability of rice protein isolate.

Rice protein isolates (RPI) are promising plant-protein sources but present low solubility and poor surface activity in neutral conditions. Improving these characteristics is a crucial challenge to capitalize on them. This is the first work performing pH-shifting, ultrasound, and heat treatments on a commercial RPI.

Functional Hybrid Nanoemulsions for Sumatriptan Intranasal Delivery.

In recent years, advanced nanohybrid materials processed as pharmaceuticals have proved to be very advantageous. Triptans, such as the commercially available intranasal sumatriptan (SMT), are drugs employed in the treatment of painful migraine symptoms. However, SMT effectiveness by the intranasal route is limited by its high hydrophilicity and poor mucoadhesion.
