biopolymer based nano-complex is a category of nano-carriers which are produced by interaction between protein and polysaccharide. they can carry hydrophobic nutriciuticals in aqueous solutions and also cause to increase of protection and bioavailability of encapsulated active materials. in this research, gellan-caseinate complexes containing omega3 were produced by adding gellan solutions to c...

Background and Objectives: The objectives of this study were to produce a nutritious stable condiment with uniform quality based on lime juice that could improve the quality of commercial lime juices in food products and investigate independent effects and interactions of hydrocolloids on the final product. Materials & Methods: Novel formulations were developed by adding two types of gums, incl...

Gel dosage forms are successfully used as drug delivery systems to control drug release and protect the medicaments from a hostile environment. The main objective is to formulate and evaluate in situ oral topical gels of clotrimazole based on the concept of pH triggered and ion activated systems. The system utilizes polymers that exhibit sol-to-gel phase transition due to change in specific phy...

Gellan Gum (GG) was modified with N-vinyl Formamide (NVF) through PDP/Ag + redox system initiated graft copolymerization in a thermostatic water bath at 35°C under nitrogen atmosphere. The highest percentage of grafting (186%) and the lowest homopolymer content (22.2%) were achieved through a systematic optimization of the polymerization variables, including reaction time, temperature, and conc...

5-Fluorouracil loaded calcium-zinc-gellan and calcium-zinc-gellan-ethyl cellulose microbeads were successfully prepared by simple ionotropic gelation and oil in water ionotropic gelation technique, respectively. Prepared microbeads were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and evaluated for particle size, drug content, encapsulation efficiency, ...

Innovative hydrogels obtained by physical and chemical crosslinking of deacylated Gellan gum have been characterized in terms of water uptake, rheological properties and compressibility, and the behaviour of the tested materials, according to the type of the obtained network, is thoroughly discussed. The release from the various gels of loaded model molecules of different steric hindrance was a...

This study investigated the in vitro acid-induced gelation of mixed systems of two biopolymers; low acyl and high acyl gellan gum. Rheological and texture analysis showed that these mixed gels displayed textures that lay between the material properties exhibited for the low and high acyl variants. DSC analysis showed that mixtures of the low acyl and high acyl forms exhibit two separate conform...
