Effect of sodium alginate coating enriched with horsemint essential oil (HEO) on the quality of bighead carp (Aristichthys nobilis) fillets at refrigeration temperature (4 ± 1°C) was studied. Bighead carp fillets were coated with neat sodium alginate (SA) and sodium alginate containing 0.5 and 1% v/v of HEO and their quality changes in terms of total volatile basic nitrogen (TVB-N), peroxide va...
The effects of coatings based on sodium alginate (S.A) and carboxyl methyl cellulose (CMC) on the color and moisture characteristics of potato round slices were investigated. It is the first time that this combination of polysaccharides is used as edible coating which alone had the best performance as inhibitor of potato color discoloration during the storage of 15 days at 4C. When ascorbic aci...
We present unique molding/bonding processes to fabricate microstructured Ca-alginate hydrogel plates. We employed propylene glycol alginate (PGA), an ester derivative of alginate, which suppresses the shrinkage of sodium alginate (NaA) during the gelation process, and prepared microstructured hydrogel plates via molding. Also, a bonding procedure utilizing polycation coating is presented to obt...
BACKGROUND Absorption of antigens onto chitosan microparticles via electrostatic interaction is a common and relatively mild process suitable for mucosal vaccine. In order to increase the stability of antigens and prevent an immediate desorption of antigens from chitosan carriers in gastrointestinal tract, coating onto BSA loaded chitosan microparticles with sodium alginate was performed by lay...
Due to its bioactivity, hydroxyapatite (HAp) is one of the most perspective materials for controlled drug delivery. Biodegradable polymers like chitosan and sodium alginate are used as coating materials for ceramic scaffolds. In this work the application of HAp/sodium alginate or chitosan composite materials which provide controlled lidocaine release is discussed. The polymers and lidocaine hyd...
Rifampicin biodegradable microcapsules were prepared by feasible emulsification-ionic gelation method for a novel controlled release product. Sodium alginate and Carbopol 974P were used as coating polymers in different ratios 1:1, 1:2, 1:3 and 1:4 to obtain elegant microcapsules. The formulations were characterized for encapsulation efficiency, drug loading, sieve analysis, scanning electron mi...
Achieving high quality of a coated food product is mostly dependent on the characteristics of the food material to be coated, the properties of the components in the coating solution, and the obtained coating material. In the present study, usability and effectiveness of various components as well as their concentrations were assessed to produce an effective coating material. For this purpose, ...
Probiotic microorganisms have been shown to provide specific health benefits when consumed as food supplements or as food components. The main problem of such products is the poor survival of the probiotic bacteria in the low pH of gastric fluid. However the use of synthetic excipients for enteric coating to prevent the exposure of microorganisms to gastric fluid is limited in food supplementar...
It has been found that the adsorption of antigens onto chitosan particles is an easy and unique mild loading process suitable to be used with vaccines. In order to increase the stability of this particles and to prevent an immediate desorption in gastrointestinal fluids, a coating process with sodium alginate was developed. One of the challenges of this developing process was to keep the partic...
