The aim of this work concerns the manufacturing process of gluten-free functional spaghetti based on maize flour and oat bran, enriched with b-glucans (22%). More specifically, the goal of the study was to obtain oat bran-loaded maize spaghetti with sensory properties close to unloaded pasta. To this aim, the study has been organized in two subsequent trials. In the first one, the oat bran amou...

Cereal Chern. 75(3):354-359 The solution rheological behaviors of OATRIM-1O and cooked oat bran were investigated. The rheological properties of the materials were investigated using both thixotropic loop and small-amplitude oscillatory shear experiments. The cooked oat bran exhibited shear-thinning behavior during a thixotropic loop experiment over a shear rate range of a250/sec. The shear-thi...

The evaluation and development of validated models for the nonlinear viscoelastic (VE) behavior of materials is an important area of research, which has impact on a number of industrial processes including those in the food industry. Various nonlinear VE models have been developed over the years and evaluated for petroleum-based polymers, however, our understanding of the nonlinear VE behavior ...

The nasal mucosa provides a potentially good route for local and systemic drug delivery. However, the protective feature of the nasal cavity make intranasal delivery challenging. The application of mucoadhesive polymers in nasal drug delivery systems enhances the retention of the dosage form in the nasal cavity. Several groups have investigated using low acyl gellan as a drug delivery vehicle b...

The effects of concentration and particle size nano-Fe3O4 particles on the evolution structural build-up cementitious paste under magnetic field are experimentally investigated then verified by theoretical calculations. Three types with various sizes exploited. results show that liquid-like properties incorporated pastes increase immediately after initiation an external extent this increment in...

The rheological behaviour of polymer melts and dilute polymer solutions in elongational flow have been extensively examined through experiments and theoretical predictions. However, an experimental study to understand the extensional rheological properties of polymer solutions in the semi-dilute regime is currently lacking in terms of a systematic examination of the effects of concentration and...

Simulations show that the kinetics of permeant fluids in viscoelastic matrices depends on the rheological and chemical properties of the material. Fick’s law fails to describe transport through viscoelastic materials because of the stress exerted on the incoming fluid which causes a delay. Reversible binding to immobilizing sites also retard permeation of molecules. The effects of mechanical pr...

This work presents an innovative experimental device conceived to characterize the time-dependent behavior of hygroscopic materials, as wood, at controlled moisture content and temperature. This device, the WAVE, permits the determination of the viscoelastic properties of samples, using harmonic tests at frequencies varying from 5.10 Hz to 10 Hz. Conceived to work up to 5 bar, it allows tests i...

Recombinant spider silk has emerged as a biomaterial that can circumvent problems associated with synthetic and naturally derived polymers, while still fulfilling the potential of native material. The artificial protein NT2RepCT be produced spun into fibers without use harsh chemicals here we evaluate key properties dope at native-like concentrations. We show recapitulates not only overall seco...
