DESCRIPTION
BS EN 17270:2019
This standard BS EN 17270:2019 Animal feeding stuffs: Methods of sampling and analysis. Determination of theobromine in feed materials and compound feed, including cocoa derived ingredients, by liquid chromatography is classified in these ICS categories:
- 65.120 Animal feeding stuffs
This document specifies a test method for the determination of theobromine in feed material or compound feed in the working range 27 mg/kg to 307 mg/kg using liquid chromatography coupled to a UV detector (HPLC-UV) or in the working range 49 mg/kg to 307 mg/kg using liquid chromatography with tandem mass spectrometry (LC-MS/MS).
This method has been fully validated using complementary compound feed for adult dogs and complementary compound feed for horses.
This method is also considered applicable for determining theobromine in baking chocolate using either HPLC-UV or LC-MS/MS systems.
The working range can be extended provided the extended range is validated.
