in the present study, floating drug delivery beads (fdds) were prepared with sodium alginate/ starch blend as a matrix, sodium hydrogen carbonate as a pore forming agent, methyl cellulose as a binder and barium chloride solution as a hardening agent. in order to prepare the beads with different porosity and morphology the ratio between pore forming agent to polymer blend and ratio of the consti...

Considering the high interest in using pulses production of staple foods, including pasta, this study aimed at investigating effect pre-gelatinisation on overall quality pasta from red lentils. Pre-gelatinized flours showed a lower gelatinisation temperature (up to about 57 °C vs. 65 °C) and higher retrogradation tendency than native flour. Such changes resulted water absorption capacity 1.23 0...

Gelatinized wheat, potato and waxy maize starches were treated enzymatically in order to increase the degree of branching of the amylopectin fraction and thereby change the starch degradation profile towards a higher proportion of slowly digestible starch (SDS). The materials were characterized by single-pulse (1)H HR-MAS NMR spectroscopy and in vitro digestion profile according to the Englyst ...

Fibers are important microstructural elements in many foods and calcium alginate fibers may find applications in the structuring of many food analogues. Fiber properties depend largely on their uniform diameter and mechanical properties. The main objective of this research is to production of fibers calcium alginate of regular diameter and to present the effect of concentrations sodium alginate...

Ionically crosslinked alginate hydrogels are attractive scaffolds because of their biocompatibility and mild gelation reaction that allows for gentle cell incorporation. However, the instability of ionically crosslinked hydrogels in an aqueous environment is a challenge that limits their application. This report presents a novel method to control the dimensions and mechanical properties of ioni...

Hydrocolloid and calcium alginate are used to treat cutaneous injuries and many health professionals do not know about its cicatrization effects. This study had the objective to identify the evidences of the action of the hydrocolloid and calcium alginate dressing in the treatment of cutaneous injuries. The method of integrative review was used. 12 studies with evidence levels I, II, III and IV...

OBJECTIVE To assess the benefit of a new technique of a Plastibell circumcision supported by a ventral calcium-alginate fibre dressing, to reduce bleeding from the frenular vessels, the commonest complication of Plastibell circumcision. PATIENTS AND METHODS This was a retrospective study of 200 neonates circumcised in the Royal Bahrain Hospital over a 2-year period from 2012 to 2014. They had...

Potato starch-based emulsion gels were fabricated that consisted of whey protein-coated oil droplets dispersed in a gelatinized starch matrix. The impact potato concentration (0–16%) on the rheological properties, water distribution, and vitro digestive behavior was examined. exhibited shear-thinning viscoelastic properties. apparent viscosity increased with progressing concentration, stronger ...

Here we propose a novel electrochemical lithography methodology for fabricating calcium-alginate hydrogels having controlled shapes. We separated the chambers for Ca2+ production and gel formation with alginate with a semipermeable membrane. Ca2+ formed in the production chamber permeated through the membrane to fabricate a gel structure on the membrane in the gel formation chamber. When the ca...

A general mathematical model for a fixed bed immobilized enzyme reactor was developed to simulate the process of diffusion and reaction inside the biocatalyst particle. The modeling and simulation of starch hydrolysis using immobilized α-amylase were used as a model for this study. Corn starch hydrolysis was carried out at a constant pH of 5.5 and temperature of 50°C. The substrate flow rate wa...
