Optimization of the effect pectin and carboxymethyl cellulose gums on oil uptake, textural properties color changes French fries using response surface methodology

Interactions of fibrinogen with dextran sulfate, dextran, and carboxymethyl cellulose were investigated by turbidity measurement, chemical analysis, and electrophoresis. Dextran sulfate and fibrinogen combined even in the physiological pH region where both of them have negative net charges, and formed a precipitate and soluble complex. Since no complex formation was observed in the case of dext...

Objective: To evaluate the antimicrobial properties and dental pulp stem cells (DPSCs) cytotoxicity of synthesized carboxymethyl cellulose-silver nanoparticles impregnated on titanium plates. Material and methods: The antibacterial effect of silver nanoparticles in a carboxymethyl cellulose matrix impregnated on titanium plates (Ti-AgNPs) in three concentrations: 16%, 50% and 100% was determine...

Three-dimensional (3D) bio-printing is a revolutionary technology to reproduce a 3D functional living tissue scaffold in-vitro through controlled layer-by-layer deposition of biomaterials along with high precision positioning of cells. Due to its bio-compatibility, natural hydrogels are commonly considered as the scaffold material. However, the mechanical integrity of a hydrogel material, espec...

Microbulbifer strain CMC-5 produces agarase, alginate lyase, xylanase, carboxymethyl cellulase and carrageenase. The extracellular production of the above carbohydrases was investigated by growing Microbulbifer strain CMC-5 in a sea water based medium containing homologous/heterologous polysaccharides as a single substrate or as a combination of mixed assorted substrate. Presence of singular ho...

Collagen was extracted from the skin of pigs, and blended with sodium alginate, starch, and sodium carboxymethyl cellulose. Food packaging films were obtained by crosslinking the blend with glutaraldehyde. Fourier transform infrared spectroscopy (FT-IR), SEM and TGA analyses were used to characterize the resulting films. A strong hydrogen bonding was detected between the composite film molecule...

This thesis project aimed to fractionate cornstalk into cellulose and lignin, and utilize the crude cornstalk-derived cellulose for the production of sodium carboxymethyl cellulose and the lignin for the sybthesis of bio-based phenol-formaldehyde resole resins as wood adhesives. In this thesis work, cornstalk was efficiently fractionated into crude cellulose and crude lignin in mixed solvents o...

This work investigated the redispersion and setting behavior of highly loaded (~ 18 wt.% solids in water) pastes cellulose nanofibrils (CNFs) with carboxymethyl (CMC). A single-screw extruder was used to continuously process CNF + CMC into cord. The adsorption onto CNFs assessed through zeta potential titration which revealed a surface charge change ~ 61% from ? 36.8 mV 0.094 mmol/g COOH for pu...

Endoglucanase 2 (EG2) of the cellulolytic ruminal anaerobe Bacteroides succinogenes is a 118-kilodalton (kDa) enzyme which binds to cellulose and produces cellotetraose as the end product of hydrolysis. The purified enzyme was treated with the protease trypsin in an attempt to isolate peptides which retained the ability to either hydrolyze soluble carboxymethyl cellulose or bind to insoluble ce...
