Abstract Alginates are natural polysaccharides that extracted from brown seaweed varieties and it is widely used for their rheological properties. The main step in the extraction protocol of sodium alginate alkaline extraction. Sodium was produced by dipping 1% formaldehyde 2.5% carbonate solution properties were studied following standard methods. amount yield 31.7% Sargassum wightii . moistur...

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...

AIM To assess the efficacy and tolerance of sodium alginate compared to cisapride in patients suffering from reflux symptoms, without severe oesophagitis. METHODS A total of 353 patients with symptoms of reflux oesophagitis (average age 40 years, 51% men, 33% smokers, 43% consumers of alcoholic drinks) were selected at random--180 treated with sodium alginate (4 sachets per day) and 173 treat...

Abstract Grafting of styrene (S) onto biopolymer Sodium Alginate (NaAlg) via free-radical polymerization forming (NaAlg-g-PS), using potassium persulfate K 2 S O 8 (KPS) as initiator. Fourier-transform infrared spectroscopy (FT-IR) and Proton nuclear magnetic resonance ( 1 H-NMR) characterized the formed grafted copolymer scanning electron microscope (SEM) to show changes in surface morphology ...

The effects of whey protein (12%) and sodium alginate (0.5%) on chemical, microbial and sensory changes and shelf life in kilka during frozen storage are investigated for up to 6 months. Total bacteria count and Staphylococcus bacteria counts(2 / 51 and 1 / 44 log CFU/g) in coated samples showed decrease in comparison with control samples(3.21- 2.28 log CFU/g). Moisture of coated samples had s...

BACKGROUND In this work, support vector regression (SVR) was applied to the optimization of extended release from swellable hydrophilic pentoxifylline matrix-tablets and compared to multiple linear regression (MLR). METHODS Binary mixtures comprising ethylcellulose and sodium alginate were used as the matrix-former. The matrix-former : drug weight ratio and the percentage of sodium alginate i...

The choice of an impression material for a particular situation depends on the treatment being provided, operator preference, and so on. Even with the introduction of more advanced and more accurate rubber base impression materials, irreversible hydrocolloid impression materials have stood the test of time. This article gives a detailed perspective of how best to make alginate impressions.
