Development of PVA/gelatin nanofibrous scaffolds for Tissue Engineering via electrospinning
(IOP Publishing, 2018)
The electrospinning process is an emerging and relatively easy technique to prepare three-dimensional matrices with micro- and nanofibers. To achieve it, aqueous polymer solutions from synthetic or natural polymers are ...

Reversible pH-sensitive chitosan-based hydrogels. Influence of dispersion composition on rheological properties and sustained drug delivery
(MDPI, 2018)
The present work deals with the synthesis of micro-structured biomaterials based on chitosan (CTS) for their applications as biocompatible carriers of drugs and bioactive compounds. Twelve dispersions were prepared by ...

Gellan gum fluid gels: influence of the nature and concentration of gel-promoting ions on rheological properties
(Springer, 2018-11)
Low-acyl gellan gum fluid gels were obtained using two different gel-promoting cations under the same processing conditions, and their rheological properties were investigated. For that reason, stress and frequency sweep ...

Heat-induced gelation of egg yolk as a function of pH. Does the type of acid make any difference?
(Elsevier, 2018-07)
The objective of this study was to assess the influence of reducing pH from its native value on the heat-induced gelation behaviour of egg yolk by monitoring its linear viscoelastic properties. Three acids differing in ...

Influence of pH value on microstructure of oil-in-water emulsions stabilized by chickpea protein flour
(SAGE Publications, 2018-05)
Food industry is highly interested in the development of healthier formulations of oil-in-water emulsions, stabilized by plant proteins instead of egg or milk proteins. These emulsions would avoid allergic issues or animal ...

Effect of temperature and shear on the microstructure of a microbial polysaccharide secreted by Sphingomonas species in aqueous solution
(Elsevier, 2018-10-15)
Diutan gum is a biological polymer produced by Sphingomonas sp. In aqueous solution it shows gel-like structure under quiescent conditions. However, the flow-induced evolution of its viscoelastic properties and its ...

Rheology, microstructural characterization and physical stability of W/α-PINENE/W emulsions formulated with copolymers
(Elsevier, 2018)
In this work the microstructure and the physical stability of emulsions containing α-pinene and gellan gum were studied as a function of Atlas™ G-5000/Atlox™ 4912 copolymer mass ratio, R, used as emulsifier. In order to ...

Effect of ozone treatment on postharvest disease and quality of different citrus varieties at laboratory and at industrial facility
(Elsevier, 2018)
The effects of continuous and intermittent (simulating a day-night cycle) exposure to ozone enriched atmosphere (from 1.6 to 60 mg kg−1) at 5 °C for 28 d and subsequent shelf life at 20 °C for 15 d on six citrus varieties ...

Formulation and optimization of emulsions based on bitter fennel essential oil and EO/BO block copolymer surfactant
(Elsevier, 2018)
The influence of EO/BO block copolymer surfactant concentration in the range (1–5% (m/m)) and emulsification time on the emulsion stability and droplet size distribution of bitter fennel essential oil-in-water emulsions ...

Effect of pH and nanoclay content on the morphology and physicochemicalproperties of soy protein/montmorillonite nanocomposite obtained byextrusion
(Elsevier, 2018)
The present work attempts to clarify the influence of montmorillonite nanoclay content and pH on the me-chanical properties of extruded soy protein nanocomposites. The mechanical behaviour is dominated by theformation of ...
