Anwendung des Tocopherolmusters zur Erkennung von Fett- und Ölvermischungen

Utilization of the Tocopherol pattern for Recognition of Fat and Oil Adulterations The determination of the tocopherols is one of the possibilities for purity control because many oils and fats have a characteristic natural tocopherol-content with a typical tocopherolpattern. It is shown, that there are some problems in the determination by HPLC (preparing of the samples, identification). A classification of the oils and fats is given, which demonstrates not only the possibilities but also the limits for purity control.
