    Viscoelastic Properties of Processed Cheese as a Function of Pectin Concentration

  • Original language description

    In this paper the effect of pectin concentration (0.2, 0.4, 0.6 and 0.8% w/w) on viscoelastic properties of model processed cheeses with 40% w/w dry matter and 50% w/w fat in dry matter after 42 days of storage at temperature 6+/-2 °C has been studied. The samples were analysed by dynamic oscillation rheometry with plate-plate geometry. Complex modulus (G*) and loss tangent (tan &#61540;) were calculated for reference frequency 1 Hz. The present work found that with the increasing concentration of pectin the complex modulus (G*) rose and loss tangent (tan &#61540;) decreased. In general, all samples with pectin were firmer than processed cheeses without it and, furthermore, created gels were more elastic.

    Vliv koncentrace přidaného pektinu na viskoelastické vlastnosti tavených sýrů

  • Czech description

    Byl sledován vliv přídavku pektinu (0.2, 0.4, 0.6 and 0.8% w/w) na viskoelastické vlastnosti modelových tavených sýrů (40 % sušina, 50 % tuku v sušině) skladovaných 42 dní při tepltotě 6 +/- 2 °C. Ke studiu byla použita dynamická oscilační reometri s měřící geometrií deska-deska. Modelové tavené sýry s přídavkem pektinu byly tužší než vzorky bez pektinu. Přídavek pektinu do taveného sýra způsobil zvýšení elasticity vzniklého gelu.
