Title Diacetyl emissions and airborne dust from butter flavorings used in microwave popcorn production
Bibliographic information Oct. 2006, Vol.3, No.10, p.530-535. Illus. 9 ref.
Abstract Occupational exposure to butter flavourings has been associated with chronic obstructive lung disease. Severe respiratory effects have been reported in rats exposed to butter flavouring vapours and to diacetyl, a diketone found in most butter flavourings. This study assessed diacetyl emissions and airborne dust levels from flavourings used by several microwave popcorn manufacturing companies. Samples of flavourings were heated to 50░C, and gas chromatography was used to measure the organic compounds emitted. Workplace air sampling was also conducted for diacetyl and for total and respirable dust during the mixing of flavourings with heated soybean oil. Powder flavourings were found to give off much lower diacetyl emissions than pastes or liquids. However, a substantial amount of the airborne dust generated by handling powder flavourings was respirable and could thus pose its own respiratory hazard. Companies that use butter flavourings should consider flavourings with lower diacetyl emissions and the use of ventilation and engineering controls to minimize exposures. Until controls are fully implemented, companies should institute the mandatory use of respirators for all exposed workers.
