 Analytical Methods for Components in Foods

It is neither the purpose, nor the intention of the Compilers' Toolbox™ to go deeper into the subject of analysing food components. In addition to Greenfield and Southgate, there are other prominent places to find the information on proper analytical techniques for developing food composition data.

However, the collection of nutrient values from the literature and unpublished sources requires critical assessment of all available data. To accomplish such a task demands that the procedures used for analysis be carefully scrutinized. The diversity of analytical methods, the numbers of nutrients being assessed, and the various forms of the nutrients make this task quite difficult.

Work on describing proper methods regarding components in foods has been carried out in connection with the European projects, EuroFIR Nexus and TDS-EXPOSURE. The result is GAMA - Guidelines for Assessment of Methods of Analysis, a wiki formerly hosted by the Helsinki University (you need to register to get access then search for GAMA in the search box in upper right hand corner). Once logged in, you have direct access via the links below.

The present wiki is currently hosted on the EuroFIR/Metrofoods/TDSExposure site (Metrofood Wiki)

 GAMA - Guidelines for Assessment of Methods of Analysis - Nutrients

The EuroFIR GAMA - Guidelines for Assessment of Methods of Analysis contains description on proper methods to be used in the analysis of nutrients and contaminants.
Currently, the following information for vitamins is available:
