The effect of plant-derived hydrocolloids on the physicochemical, viscoelastic and organoleptic properties of processed cheese sauces

Original language description

The current study investigated the effects of three plant-derived hydrocolloids (pectin, agar, and guar gum) at varying concentrations (0.25, 0.50, 0.75, and 1.00% w/w) on the physicochemical, viscoelastic and organoleptic properties of processed cheese sauces (PCS). The addition of hydrocolloids had no significant impact (P≥0.05) on pH values (ranging from 5.83 to 5.92) or dry matter content (in the range of 30.03–31.92% w/w). On the contrary, emulsion stability and viscoelastic properties were significantly affected (P&lt;0.05) by the type and concentration of applied hydrocolloid. Emulsion stability values increased progressively with higher hydrocolloid concentrations, with guar gum yielding nearly complete stabilization effect (≈100%). Moreover, agar and pectin also enhanced emulsion stability, reaching maxima of 99.4% and 98.9%, respectively, indicating all used hydrocolloids function effectively as stabilizers. Rheological analysis revealed that control samples (CS; with no hydrocolloid addition) and PCS samples with low pectin concentrations (0.25–0.50% w/w) exhibited predominantly viscous behavior at low frequencies, whereas all other samples demonstrated weak gel characteristics dominated by an elastic character. Furthermore, gel strength (AF), storage (G&apos;), loss (G&apos;&apos;), and complex (G*) moduli, increased with higher hydrocolloid concentration (P&lt;0.05). Additionally, agar and guar gum (at all tested concentrations) and pectin (at concentrations ≥0.50% w/w) imparted a more elastic behavior compared to the CS. Sensory analysis of texture (hardness) supported rheological findings. These results confirm that the tested hydrocolloids act as effective gel-forming and stabilizing agents in PCS, enhancing both emulsion stability and viscoelastic properties.
