Apparatus and method for measuring the content of intramuscular fat in carcasses or parts thereof

摘要

The apparatus for measuring the intra-muscular fat in carcasses or parts of carcasses or the total content of fat in minced meat has a first pair of electrodes for insertion into a carcass or part of a carcass or into minced meat. An alternating current (AC) generator is connected to these electrodes. Second and third pairs of electrodes are inserted parallel to the first pair. Both the second and third pairs have measurement circuits to measure the voltage and phase between the electrode pairs after insertion. The needle or bar shaped electrodes are tapered and insulated apart from 5-20 mm long free end sections. Electrodes are separated by 10-100 mm with each electrode 10-50 mm from the nearest of the first electrode pair. The portable unit for on-line use has a display output. The AC frequency applied to the first electrode pair may be changed in an exponential series to give different measurements.
