    2010-11-6 · Thickening agents. Hydrocolloids are frequently used in several foods for thickening. The process of thickening involves the non-specific entanglement of conformationally disordered polymer chains; it is essentially a polymer-solvent interaction (Philips et al. 1986).Thickening occurs above a critical concentration known as overlap concentration (C*).
