There are other foods that cause dementia. Also, a modified OSHA method 1016 is being investigated to improve detection limits by replacing flame ionization detection with mass spectrometric detection negating the need to derivatize. Also recognize that the flavor blends that do contain diketones have very very small amounts of the ingredient. Toxicologic Pathology. Thus, measuring diacetyl exposures identifies hazards. Using them can also decrease exposures to the thousands of flavoring chemicals that have not been studied for toxicity after inhalation and do not have occupational exposure limits. Foods containing diacetyl that occurs naturally include: Dairy products such as milk, cheese, yogurt and butter. Commercial flavorings used in the flavoring manufacturing and food production industries are often complex mixtures of flavoring chemicals, many of which are volatile, meaning that they evaporate into the air from their liquid or solid form. It forms from sugars and lipids via various bacteria and heat treatment in various foods and beverages, such as milk. 1 [6], Diacetyl and acetoin are two compounds that give butter its characteristic taste.
