Rational parametres on the basis of experimental data of measurement rheological characteristics of a muscular fabric of beef are received and proved by a penetration method. The control point was L.dorsi between 7–8 back vertebras. The researches are spent by means of dynamic penetrometer at the use ofconic indentors with angles at tops 30°, 20°, 10° and effort of resistance of a product equal 0.5 kg. It is established that the greatest value of the depth of immersing is received at a cone of 10°. The chosen cone provides the minimum disorder of experimental data that allows to consider it rational and to use for researchesof rheological characteristics of the whole musclemeat of raw materials.
