Process contaminants of the food industry were evaluated by the EFSA (European Food Safety Authority). Zinsser Analytic invented a new system for contaminant analysis in food and oil samples in collaboration with a food quality and safety lab, addressing your everyday workflow challenges with the following substances:
With our system you will have a lot of advantages combined:
The presented automated high throughput sample liquid handling system performs four different well established methods to analyze 3-MCPD and 2-MCPD (free and ester form), as well as glycidyl ester in oil and fat containing samples.
With the standard pipetting tips almost every liquid can be handled. The gripper for racks and vials can handle every needed vial and rack type, as well as rack lids. Sonication of vials could be performed with the incorporated ultrasonic bath. The needed centrifugation steps are performed with the centrifuge underneath the workbench with a corresponding cut-out for the gripper to install the racks with the centrifuge.
The methods applied can be changed, depending on the certified process desired: Alkaline transesterification of glycidol to 3-MCPD (DGF method, Cd 29c-13), alkaline transesterification of glycidol to 3-MBPD (SGS 3-in-1 method, Cd 29b-13), acidic transesterification (Unilever combined method, Cd 29a-13) and single compound analysis.
Unilever combined method (Cd 29a-13) for the simultaneous quantification analysis of 2- and 3-MCPD and GE in edible oils and fats.
SGS 3-in-1 method (Cd 29b-13) for the quantification analysis of 2- and 3-MCPD esters and GE in edible oil and fats.
DGF method (Cd 29c-13) for the differential quantification of 3-MCPD esters and GE in edible oils and fats.
