1) A measuring apparatus of jelly strength, capable of adjusting the loading speed, was devised and some factors exerting and effect on the measurement value were tested.2) The relation between the breaking load and the breaking time is shown by an experimental formula W=a+b/t. The higher the loading speed, the larger the breaking load.3) The relation between the breaking load and the depth of a sample is shown by the formula W=α{1-exp(-βα)}. The jelly strength of a sample in a small depth shows a smaller value than its proper one. The minimum depth of samples required for measuring the breaking load varies with jelly used.4) The relation between the jelly strength and the diameters of piston and sample is shown by the formula S=a+b/(2r)^η+c/2ψ-2r. The jelly strength decreases to an extreme value in accordance with the enlargement of the diameter of piston but it tends to be affected by the diameter of sample. [table]Therefore, it is concluded that the measurement value of jelly strength is influenced by some experimental conditions-the loading speed, the diameter of piston and the size of sample.
