Title Diacetyl exposures in the flavor manufacturing industry
Bibliographic information Nov. 2008, Vol.5, No.11, p.679-688. Illus. 16 ref.
Abstract Diacetyl is used in the food industry as a flavour. Exposure to diacetyl has been linked to bronchiolitis obliterans. In this study, exposures were monitored at 16 small-to medium-sized flavour facilities, during which 181 personal and area samples were collected in various processing areas. Diacetyl concentrations ranged from non-detectable to 60ppm. Half of the samples were below the limit of detection, and the mean diacetyl concentration for all processes was 1.80ppm. Mean diacetyl levels during powder operations were generally higher (4.24ppm) than during operations involving liquids (2.02ppm). Peak exposures may be considerably higher and warrant further research.
