| Resumen: | This International standard specifies a procedure for the determination of the degradation products pheophytin a, a' and pyropheophytin a of chlorophylls. The method is applicable to vegetable fats and oils only. During the systematic review of ISO 29841:2009 in 2014, it was proposed to give a more detailed explanation for the home-made silica mini-columns in the note to 6.6. Furthermore, it is necessary to replace the size of the flasks in subclause 6.2 as 10 ml is not big enough and sample could be lost when locating in the rotary evaporator. It was also agreed to change the title of subclause 9.2 to emphasize the fact that it is the relative content of the analytes which is calculated. |
