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

A total of 249 maize kernel samples from 8 maize-producing provinces of China were collected after the harvest season in 2014. All samples were analysed using high-performance liquid chromatography. The incidences of FBs (FB1 + FB2) from Guizhou, Hebei, Inner Mongolia, Shanxi, Chongqing, Liaoning, Heilongjiang, and Henan provinces were 71.4%, 73.8%, 28.0%, 52.6%, 85.0%, 87.5%, 38.1%, and 100.0%, respectively. The average concentration of FBs was 817 µg kg−1 and the concentrations ranged from <6 to 15,252 µg kg−1. Among the 249 maize kernel samples, 28 samples exhibited higher levels as set by the Food and Drug Administration (2000 µg kg−1), whereas 12 samples exhibited higher levels as set by the European Commission (4000 µg kg−1). The average exposure to FBs (0.12 µg kg−1 body weight/day) is within the provisional maximum tolerable daily intake of 2.0 µg kg−1 body weight as set by the Joint FAO/WHO Expert Committee on Food Additives.
