Tofu with Many Probes
Firmness, area of work, stiffness
To illustrate the types of issues highlighted by different probes we tested tofu with a variety of common probes attached to the TA.XTPlus Texture Analyzer. The tofu was tested in the plastic containers in which it was sold in supermarkets and health food stores after excess water had been drained. The probes we used were a TA-52 2 mm diameter stainless steel puncture probe, a TA-8 ¼” diameter stainless steel ball probe, a TA-18 ½” diameter stainless steel ball probe, a TA-2 60 degree acrylic cone probe, a TA-10 ½” diameter acrylic cylinder, a TA-11 1” diameter acrylic cylinder, a TA-42 knife with a 45 degree chisel blade (3 mm thick and 68 mm wide), and a TA-43 knife blade with a flat end (3 mm thick, 68 mm wide).
