The graph shows two different mayonnaises: a traditional type with a yield value of 360 Pa and a soft, low-fat formulation with a yield value of 30 Pa.

In addition, the power-law model (Equation (1)) was used to compute the flow behavior index and consistency coefficient values of the extracts 14.

This was performed by the computer software provided by the supplier. The RST-SST with a quick 30-second yield test describes the fluid using yield stress value and modulus (slope of line leading up to yield stress). The graphs of shear stress versus shear rate were analyzed using V3.1 Rheocalc software to obtain the rheological indexes. Traditionally testing with a viscometer and accessory for some mayonnaises may produce variations in the viscosity centipoise (cP) values due to the spindle as it travels through the fluid. These data reflect Regular вЂњAвЂ™sвЂќ significantly firmer texture. See the complete profile on LinkedIn and discover EswaraвЂ™s connections and jobs at similar companies.

The final viscosity value of Regular вЂњAвЂќ is higher than that of Low-fat вЂњLвЂќ. View Eswara bajiвЂ™s profile on LinkedIn, the worldвЂ™s largest professional community.

The initial slope of the Viscosity-versus-Time curve is greater for mayonnaise Regular вЂњAвЂќ than for mayonnaise Low-fat вЂњLвЂќ. This higher peak corresponds to a higher yield stress. Mayonnaise Regular вЂњAвЂќ, whose response is given by the red curve, has a much higher peak viscosity value than does Low-fat вЂњLвЂќ, whose response is given by the blue curve. The difference between the two materials is significant. Typical data from a comparison of two different products, Regular вЂњAвЂќ and Low-fat вЂњLвЂќ are shown below. Automated data acquisition may be performed with the any DVIII / DV3 series Rheometer or DVII+ / DV2T Viscometer, for example, with Rheocalc(T) software. This test may be considered somewhat more sophisticated than the standard Helipath procedure described in the other Application Sheet. The test is run at room temperature.В Vane rheometry is relatively new, in QC applications.

The materials appear to be similar, with Regular вЂњAвЂќ being somewhat more viscous or вЂњthickerвЂќ in feel than Low-fat вЂњLвЂќ. Mayonnaise Regular вЂњAвЂќ data are in red, while Low-fat вЂњLвЂќ data are in blue. Typical automated-test data, comparing two different products, the Regular вЂњAвЂќ and Low-fat вЂњLвЂќ, are shown below:

However, automated data acquisition may be performed with the Brookfield RVDV-II+ Pro Viscometer and Rheocalc software, for example. The original test was established in the 1960вЂ™s by the Mayonnaise and Salad Dressing Institute in the USA and specified the Brookfield RVT Dial Reading Viscometer. Mayonnaise is used as a dressing, typically mixed with other foods in making salads and sandwiches, for example.
