CEN/TC 460/WG 4 is a Working Group within the European Committee for Standardization (CEN). It is named "NMR analysis" and is responsible for: Standardization of NMR-based methods for food authenticity This committee has published 1 standards.
CEN/TC 460/WG 4 develops CEN standards in the area of Information technology. The scope of work includes: Standardization of NMR-based methods for food authenticity Currently, there are 1 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
This document specifies a method for the determination of soluble 16-O-Methylcafestol and 16-O-Methylkahweol content (the sum of free forms and derivatives, e.g. fatty acid esters, henceforth abbreviated as 16-OMD = “diterpenes”) in roasted coffee (beans or ground), using quantitative proton nuclear magnetic resonance spectroscopy (1H-qNMR).
If complying with the experimental parameters described below, this test procedure has been proven for the following mass fraction range:
w16-OMD: 20 mg/kg to 2 000 mg/kg.
The mass fraction range can be expanded by suitable changes of the experimental parameters, e.g. a different weighed portion of ground coffee or the accumulation of more NMR-transients.
