Abstract

|
The back extrusion method was used to measure flow properties of 5 commerical kochujang samples with a plunger/annular cylinder geometry using a Texture Analyzer. Power law model parameters were determined from the force-distance data for back extrusions at different plunger velocities. The back extrusion method was also compared with a Haake viscometer at a controlled rate (CR) and a Carri-Med rheometer at a controlled stress (CS). Magnitudes of consistency index (K) and flow behavior index (n) determined at the back extrusion method and the Carri-Med rheometer were very close and higher than those determined at a Haake viscometer. K values of diluted kochujang samples increased with increase in total solids with a good linear correlation (R²= 0.97). The results suggest that the back extrusion test is a good method for predicting flow properties of kochujang samples.
