Application Note: Ketchup

Ketchup is a condiment or dressing. It is typically poured, "squirted" or spread onto other foods, such as hamburgers, frankfurters [or "hot dogs"], other sliced meats or poultry, French fries, and in making sandwiches, for example.

The test may be run at room temperature, or at refrigeration temperatures. The DV-I Prime provides continuous measurement of both torque and viscosity. The DV-II+Pro also provides continuous temperature measurement.

The Helipath Stand may be used with various Brookfield Viscometers or Rheometers. The choice of Spring Torque Range, spindle and speed may vary widely, depending upon the ketchup. In our example, we used a Brookfield RVDV-II+PRO, with Rheocalc v3.1 software for automated instrument control and data acquisition.
