title: [Formation and occurrence of cancer-producing hydrocarbons in cereals and possibilities for their reduction].
abstract: According to the authors' investigations every inhabitant of the GDR takes between 0.2 and 1.0 mg BaP. per year by food consumption including amounts of 0.03 to 0.17 mg on account of cereals and mill products. For the contamination of cereals the following sources are in consideration: environmental contamination on account of industry dust (distant from industry 0.1 to 0.6, near to industry 0.3 to 4.2 micrograms BaP/kg), passing over from soil to plant (with model experiments with soils more than 10 000 micrograms BaP/kg up to 22.3 micrograms BaP/kg dry matter) as well as technologically caused contamination for instance by direct fume-and-gas drying (with the use of raw lignite up to 10 micrograms BaP/kg). As it can be concluded from model experiments BaP passes to flour at milling in dependence of the extraction rate. By separating the husks prior to milling more than 50% of BaP can be removed from the stock.
