In vitro digestibility and pasting properties of epichlorohydrin modified cassava starch
(Editorial Emerald, 2016-03)
The objective of this work was to analyze the influence of epichlorohydrin concentration and reaction time on the food-grade resistant starch production and its pasting properties by using native cassava starch from ...
Control of the adsorption properties of alginate - guar gum matrix functionalized with epichlorohydrin through the addition of different flexible chain polymers as toll for the chymotrypsinogen isolation
(Elsevier Science, 2018-08)
This work addresses the obtaining and characterization of alginate-guar gum matrix, cross-linked with epichlorohydrin in the presence of different flexible chain polymers: polyvinyl alcohol, polyvinyl pyrrolidine and ...
Development of alginate microparticles as efficient adsorption matrix for protein recovery
(Elsevier, 2019-05)
Alginate microparticles were prepared by spray drying technique and chemically cross-linked with epichlorohydrin. Microparticles were characterized by size, surface morphology (SEM), zeta potential, thermal analysis (TGA/DSC) ...
Improving the properties of chitosan as support for the covalent multipoint immobilization of chymotrypsin
(American Chemical Society, 2008-07)
Changing gel structure and immobilization conditions led to a significant improvement in the covalent multipoint attachment of chymotrypsin on chitosan. The use of sodium alginate, gelatin, or κ-carrageenan, activation ...
TEOS as an improved alternative for chitosan beads cross-linking: A comparative adsorption study
(John Wiley & Sons Inc, 2014-11)
In this work the use of tetraethoxysilane (TEOS) for cross-linking of chitosan hydrogel beads was studied at the level of 1 mmol TEOS per gram of chitosan. They were compared with glutaraldehyde and epichlorohydrin ...
Prediction of breakthrough curves in packed-bed column as tool for lysozyme isolation using a green bed
(Springer, 2019-11)
The adsorption of lysozyme onto alginate–guar gum bed cross-linked with epichlorohydrin has been studied in packed-bed column. Adsorption performance was evaluated with different bed heights, flow rates and initial protein ...
Chemically modified alginate bead matrix for efficient adsorptive recovery of trypsin from fresh bovine pancreas
(American Chemical Society, 2018-09)
The adsorption of commercial trypsin (Try) onto epichlorohydrin cross-linked alginate–guar gum matrix has been studied at equilibrium in batch and in fixed bed column. Experiments were conducted to study the effect of ionic ...
Hg(II) removal from water by chitosan and chitosan derivatives: A review
(Elsevier Science, 2009-08-15)
Mercury (Hg) is one of the most toxic heavy metals commonly found in the global environment. Its toxicity is related to the capacity of its compounds to bioconcentrate in organisms and to biomagnifie through food chain. A ...
HMDSO-plasma coated electrospun fibers of poly(cyclodextrin)s for antifungal dressings
(Elsevier Science, 2016-11)
Electrospun mats containing cyclodextrin polymers (poly-αCD or poly-βCD) were developed to act as wound dressings showing tunable release rate of the antifungal agent fluconazole incorporated forming inclusion complexes. ...
