How is Carboxymethyl Cellulose used as a thickener in food?
Carboxymethyl Cellulose(CMC,E466)acts as an efficient thickener in food by dissolving in water to form a viscous colloidal solution.Its long molecular chains expand and entangle in water,increasing internal friction and creating stable visc...

How does pH affect the stability of Carboxymethyl Cellulose(CMC)?
The stability,solubility,and viscosity of Carboxymethyl Cellulose(CMC)are strongly affected by pH,primarily because CMC is an anionic polyelectrolyte whose carboxylate groups respond to changes in hydrogen ion concentration. 1.Stability in...
