A METHOD FOR RECORDING THE AMPLITUDE OF FORCE FLUCTUATIONS DURING TEXTURE TESTS1

A means of measuring the amplitude of force fluctuations during texture tests is described. A maximum-minimum module added to the electronic force recording system gives a direct readout of amplitude. The method has potential applications in research and quality control The technique is demonstrated with the back extrusion test applied to tomato juice. The results show that the maximum amplitude of the force fluctuations during extrusion is related to the graininess of the juice.
