ANNEXSupplementary provisions
ANNEX In the Annex to Decision 2009/11/EC the following Part 9 is added: ‘ Part 9 gmSCAN 1. The rules provided for in this part shall apply when the grading of pig carcasses is carried out by means of the apparatus known as ‘gmSCAN’. 2. The gmSCAN uses magnetic induction to determine the dielectric properties of the carcasses without contact. The measurement system is formed by a number of transmitter coils that generate a variable and low intensity magnetic field. The receiver coils converts the signal from the perturbation of magnetic field caused by the carcass into a complex electric signal, related to the dielectric parameters of the muscle and fat tissue of the carcass. 3. The lean meat content of a carcass shall be calculated according to the following formula: Ŷ = 55,14067 + 1 598,66166 × (Q1/CW) – 579,58575 × (Q2/CW) + 970,83879 × (Q3/CW) – 0,18993 × CW where: Ŷ = the estimated percentage of lean meat in a carcass; Q1, Q2 and Q3 = Magnetic Induction response (Volts) from the ham, middle and shoulder area, respectively; CW = warm carcass weight (in kilograms). This formula shall be valid for carcasses weighing between 60 and 120 kilograms (warm weight).’
