Apo carotenic ester content, expressed as mg/kg product is given by: Concentrated butter: (C.V)/m Butter: 0,82 (C.V)/m where C = apo carotenic ester content, ig/ml, read from the calibration graph (5.3), m = mass (g) of the test portion (5.2), 0,82 = a correction factor for the butterfat content of butter.
A quasi-peak detector shall be used for the measurement of braodband electromagnetic emissions in this Annex, or if a peak detector is used an appropriate correction factor shall be used depending on the spark pulse rate.
