Study of the Physicochemical and Rheological Behaviors of Hybrid Oleogels Based on Monoacylglycerol and Carboxymethyl Cellulose
Background and Objectives: Due to the hydrophilic nature of cellulose derivatives which are widely used in food industries, special methods should be used to dissolve these compounds in oil. In this study, carboxymethylcellulose (CMC) was used to increase strength of monoacylglycerol (MAGs) gels. In the present study, simultaneous effects of MAG and CMC on the production of hybrid oleogels were...
متن کاملElectric Properties of Carboxymethyl Cellulose
Carboxymethyl cellulose [C6H7O(OH)3x(OCH2COOH)x]n is a derivative of the regenerated cellulose [C6H10O5]n with hydroxy-acetic acid (hydroxy ethanoic acid) CH2(OH)COOH or sodium monochloroacetate ClCH2COONa. The CMC backbone consist of D-glucose residues linked by -1,4-linkage. The molecular mass of one glucose unit in CMC chain is mCMC = 146.14 + 75.04x, where x 3 is the degree of substitu...
متن کاملSynthesis, Characterisation and Flocculation Properties of Carboxymethyl Cellulose-g Acrylamide
Graft copolymers of acrylamide on carboxymethyl cellulose (d.s 0.4-0.5) were prepared by the use of ceric ion, ceric ion/reductant molecule initiator systems in aqueous medium. The graft copolymers were characterized by IR spectroscopy. The extent of graft copolymerisation was measured in terms of grafted chains as a function of both ceric ion and ceric ion/reductant molecule concentrations. It...
متن کاملRheological properties of nanocrystalline cellulose suspensions.
Rheological behavior, including linear and nonlinear, as well as transient rheology of nanocrystalline cellulose (NCC) suspensions was studied in this work. Two kinds of polymer solutions, aqueous poly(vinyl alcohol) (PVA) with flexible chain structure and aqueous carboxymethyl cellulose (CMC) with semi-rigid chain structure, were used as the suspension media to further explore the role that th...
متن کاملRheology of Carboxymethyl Cellulose Solutions Treated with Cellulases
The effect of cellulase treatments on the rheology of carboxymethyl cellulose (CMC) solutions was studied using a rotational viscometer. The rheological behaviors of CMC solutions of different molecular mass and degrees of substitution where studied as a function of time after various treatments. These solutions were subjected to active and heatdenatured cellulase, a cationic polyelectrolyte (C...
