DETERMINATION OF MOISTURE AND FATTY SUBSTANCES CONTENTS OF SOLID ADJUNCTS

Two new methods-moisture at 130-133 degrees C and fatty substances ext racted by petroleum ether-were collaboratively tested by 14 laboratori es (EBC and IOB Analysis Committee members and other laboratories), Fo r moisture the following values were obtained in the range 12 to 15% m /m, repeatability=0.13% m/m and reproducibility=0.60% mim. For fatty s ubstances in the range 0.3 to 0.9% m/m the following values were obtai ned: repeatability=(0.06 m+0.02)% m/m and reproducibility=(0.14 m+0.09 )% mim. Both methods were accepted and will replace methods 6.1 and 6. 4 respectively in Analytica EBC. The method for Fatty Substances will replace IoB methods 4.1.3 and 4.2.3. These modifications will become o perative on 1 September, 1996.
