Microencapsulation of oils using sodium alginate

Journal of Microencapsulation, 2000
The feasibility of encapsulating wheatgerm oil and evening primrose oil using sodium alginate by the emulsification method was explored in this study. It is based on the chemical reaction between the water-soluble sodium alginate and polyvalent cation, calcium, to form the water-insoluble alginate.

Interactions between gelatin and sodium alginate: UV and FTIR studies

Journal of Dispersion Science and Technology, 2020
The interaction between macromolecular chains of gelatin and anionic polysaccharide sodium alginate during the formation of polyelectrolyte complexes was examined using UV and FTIR spectroscopy. It has been shown that in an aqueous phase, where the pH is

Sodium Alginate Toughening of Gelatin Hydrogels

ACS Biomaterials Science & Engineering, 2017
Gelatin is a popular material for the creation of tissue phantoms due to its ease-of-use, safety, low relative cost, and its amenability to tuning physical properties through the use of additives. One difficulty that arises when using gelatin, especially in low concentrations, is the brittleness of the material.

Study of electrospinning of sodium alginate, blended solutions of sodium alginate/poly(vinyl alcohol) and sodium alginate/poly(ethylene oxide)

Journal of Applied Polymer Science, 2007
AbstractAlginate is an interesting natural biopolymer for many of its merits and good biological properties. This paper investigates the electrospinning of sodium alginate (NaAlg), NaAlg/PVA‐ and NaAlg/PEO‐ blended systems. It was found in this research that although NaAlg can easily be dissolved in water, the aqueous NaAlg solution could not be ...

Controlled release of insecticide carbaryl from sodium alginate, sodium alginate/gelatin, and sodium alginate/sodium carboxymethyl cellulose blend beads crosslinked with glutaraldehyde

Journal of Applied Polymer Science, 2005
AbstractInterpenetrating network polymeric beads of sodium alginate (NaAlg) and its blend with gelatin (gels) or sodium carboxymethyl cellulose (NaCMC) have been prepared by crosslinking with a common crosslinking agent, glutaraldehyde (GA), for the release of insecticide carbaryl (Carb).

Modification ofα-Amylase by Sodium Alginate

Acta Biotechnologica, 2001
Sodium alginate, activated by periodate oxidation, was covalently linked to porcine pancreatic α-amylase via reductive alkylation with NaBH4. The enzyme-polymer conjugate, purified by gel filtration on Fractogel EMD BioSEC (S), retained about 50% of the native specific amylolytic activity.

Iron Binding by Sodium Alginate

Journal of Food Science, 1983
ABSTRACT Sodium alginate was dispersed in iron chelate solutions and incubated for 10 min. The alginate was precipitated with acetone and the iron in the supernatant measured. Bound iron was calculated. The effects of pH, iron: alginate ratio, chelator, and competing cation on iron binding by alginate were determined.

Sodium Alginate Based Mucoadhesive Hydrogels

Applied Biochemistry and Microbiology, 2019
The potential use of sodium-alginate hydrogels as mucoadhesive drug delivery carriers for intranasal application is studied. It is demonstrated that the drug release rate is dependent on the drug solubility in water, the drug concentration in the carrier, and the degree of alginate crosslinking.

Solution properties of sodium alginate

Biopolymers, 1980
AbstractSodium alginate fractions derived from three different sources—Laminaria hyperboria (75% guluronate), Fucus vesicularus (95% mannuronate), and Azotobacter vinelandii (85% mannuronate)—were investigated in aqueous solution over a wide range of ionic strength and pH using the techniques of light scattering, viscometry, and osmometry.
