A method for electric treatment of a carcass after the slaughter

摘要

A method for electrical treatment of a carcass after the slaughter. The carcass is subjected to a pulsed electric voltage during 1 to 2 min. immediately after the exsanguination. The voltage is a square wave having a pulse frequency of 10 to 15 Hz, a top voltage of about 50 to 85 V and a pulse length of about 5 ms. One terminal is attached to the muzzle of the carcass and the hang rail constitutes the earth terminal. The voltage can be in one direction or the direction can be changed. The treatment can be continuously or intermittently. After the electrical treatment the carcass can be cooled rapidly without the risk of so called cold shortening. Moreover, the tenderness enzymes are released which results in a more tender end product.
