-l-guluronic acid- (G-), and MG-sequential blocks in the SA chains were not changed significantly by acid treatment. Meanwhile, the molecular weight and G/M ratio of the SA exhibited drastic variation after acid modification. The result of rheological analysis suggesting that the apparent viscosity of SA reduced from 30 to 16.4 mPa.s with the incre...

Abstract—We have prepared a composite material based on a mixture of calcium phosphates and sodium alginate and investigated their composition, morphology, and dynamic dissolution behavior. The addition of a powder material to the sodium alginate matrix causes no changes in its composition, but increases the specific surface area and resorption rat...

The climacteric nature of mango makes it ripen quickly and increases its postharvest losses. The objective of the present search was to evaluate the efficacy of 1%-3% sodium alginate edible coating for maintaining the postharvest nutritional quality and increasing the marketability of the mango fruit during storage at 15 ± 1°C and 85 ± 1% relative ...
The aim of this work was to develop green and bioactive films with sodium alginate incorporating guava leaf extracts. Seven formulations were performed with a different sodium alginate: Guava leaf water extract (WE)/ethanolic extract (EE) proportions (100:0, 90:10, 85:15, 80:20), and glycerol were used as a plasticizer. The HPLC-PDA analysis showed...
Peppas equation. The results indicated that the prepared lutein-loaded PVA/SA nanofibers have great potential as a controlled release system.
The potential of sodium alginate (ALG) and gum arabic (GA) as wall polymers for L-ascorbic acid (AA) encapsulation as a tool for their preservation against the thermo-oxidative degradation was investigated. The influence of such polymers used as wall material on the AA-content, size, encapsulation efficiency, encapsulation yield and thermo-oxidativ...
they all presented good viability. We also evaluated the maintenance of the printed shape, opening the possibility to obtain a reliable in vitro neural tissue combining 3D bioprinting and iPSCs technology, optimizing the study of the degenerative processes that are still widely unknown.
Electrochemical activity of poorly conductive metal fluorides in Li-ion batteries is contingent on their nanostructuration to reduce diffusion lengths and increase reaction kinetics. In that regard, we optimize the synthesis and electrode formulation of MnF2 to enable sufficient electrochemical activity required to study its electrochemical convers...

Lactic acid bacteria (LAB), screened and purified from the fermented yogurt, were microencapsulated in sodium alginate (SA) and attapulgite composite microcapsules by external gelation to increase their viability and stability. Surface characterization by scanning electron microscope clearly evidenced a high number of the LAB embedded in SA/attapul...

AbstractThe 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.
