Clinoptilolite is a naturally occurring zeolite, formed by the devitrification (ie the conversion of glassy material to crystalline material) of volcanic ash in lake and marine waters millions of years ago. Clinoptilolite is currently used in applications such as drinking water purification and as an animal feed additive. Euremica Environmental Ltd propose to market clinoptilolite as a food supplement in the EU. Approval is sought under Regulation (EC) No 258/97 concerning novel foods and novel food ingredients.
Before any new food product can be introduced on the European market it must be rigorously assessed for safety. In the UK the assessment of novel foods is carried out by an independent committee of scientists appointed by the Food Standards Agency named the Advisory Committee on Novel Foods and Processes (ACNFP).
Following an initial public consultation period and the discussion of this application at the 4 February 2004 and 29 September 2005 meetings of the Advisory Committee on Novel Food and Processes (ACNFP), the UK Competent Authority has formulated a negative initial opinion for this novel food application.
The application closed in September 2008.
