For both agar solutions (NA and AA),only G values were considered in this study because values of G were too low to be recorded with accuracy in the range of tested frequencies(Fig. 2B and D). Mixtures of agar/LBG exhibited intermediate behaviors, with the magnitudes of the viscoelastic parameters (G, =G/ω) lying between those obtained for the pure biopolymer solutions (Fig. 2). The increase of LBG concentration in the mixtures resulted in increased viscoelastic parameters and the shape of the curves approached that of the pure galactomannan(the non-gelling component in the mixtures).However,the magnitudes of the parameters were greater for NA/LBG (Fig. 2A and B) than for AA/LBG (Fig. 2C and D) mixtures. Chemical differences between both agars could account for the observed differences(i.e. higher
sulfate/LA ratio and more methyl groups for NA when compared to AA; Sousa &Gonc¸ alves,2015).
