Help: about the FAC B Database

The Food Additives and Contaminants - Surveillance Database is a searchable database containing all the surveillance data published in Food Additives and Contaminants Part B (FAC B) since its launch in June 2008. Search results may be viewed on screen, or downloaded into standard reports or spreadsheets by simply clicking a button. You may search the entire database by following the link Visit FAC B Database, or alternatively you may choose to move from a FAC B article through to the specific dataset that corresponds to the article you are viewing. There are links to the relevant datasets from all FAC B articles. All subscribers to the FAC B journal will be granted access to the entire database. Pay-per-view customers will be granted access to the datasets corresponding to the articles that they have purchased, but they will not be able to search the full database.

ABSTRACT

In this study, 18 different samples of unrefined coarse food salt were examined using inductively coupled plasma mass spectrometry and Fourier transform infrared spectroscopy. Additionally, microphotographs were taken to determine the visual distribution of the impurities in the salt samples. None of the salt samples analysed contained arsenic, mercury, tin, and antimony. Cadmium, chromium, nickel, lead, barium, lithium, aluminium, titanium, vanadium, cobalt, cupper, iron, zinc, manganese, magnesium, and calcium were determined in some salt samples. According to the results of FTIR analysis mainly polyamide polymer derivatives were found in Himalaya White, Himalaya, Klodawa, Nakhchivan, Delice, Guérande Flake, Guérande Celtic, Maldon, Havaii Black, Havaii Green, Havaii Red, Maras, and İzmir salts.
