Role in Food Products
The solubility of HEC is primarily attributed to its chemical structure. The hydroxyethyl groups attached to the cellulose backbone introduce hydrophilic characteristics, allowing water molecules to interact with the polymer chains. In aqueous environments, the hydrogen bonds formed between water molecules and the hydroxyl groups on HEC result in the disruption of the intermolecular hydrogen bonding present in crystalline cellulose. This disruption facilitates the dissolution of the polymer in water.
