The diacetyl drawing has been corrected. I see the old drawing - for a few minutes, hours, or days, but eventually, I see the updated one. I don't know what the rest of Wikipedia sees.
If the old one persists, I'll upload a new drawing with a different name. Brian Rock 23:24, 27 Jun 2004 (UTC)
Wouldn't the official name be butanedione instead of 2,3-butanedione? There is no other way to arrange the two oxo-groups to form a diketone! -- Malbi 22:24, 21 July 2005 (UTC)
What are typical concentrations of diacetyl in air which may be harmful? Icek 19:15, 9 May 2007 (UTC)
"Rose said that her team had measured the diacetyl released in the patient's home when the popcorn was microwaved and found levels equal to what the National Institute of Occupational Safety and Health found when it began investigating worker exposure in Midwest popcorn plants in 2001."

I've removed the following because it is (1) unreferenced, (2) does not mention diacetyl in particular at all, (3) seems to be copied wholesale from somewhere else (it refers to some non-existent section). -- Rifleman 82 20:12, 6 October 2007 (UTC)
Engineering controls are the primary methods for minimizing exposure associated with the use or manufacture of potentially hazardous flavorings. Examples include closed production systems (e.g., to eliminate handling open containers of flavorings or their chemical ingredients for placement into mixing tanks), adequate ventilation, and isolation. Whenever possible, use closed processes to transfer flavorings or their chemical ingredients.
- Isolate the mixing room and other areas where flavorings and their ingredients are openly handled.
- Maintain these work areas under negative air pressure relative to the rest of the plant.
- Use local exhaust ventilation of tanks and other sources of potential exposure (e.g., places where flavorings are openly weighed or measured) as well as general dilution ventilation of the work area to eliminate or reduce possible worker exposures.
- Obtain information about the design of appropriate ventilation systems from a qualified ventilation engineer or from Industrial Ventilation—A Manual of Recommended Practice [ACGIH 2001].
- Check ventilation equipment regularly for adequate performance, especially in areas where flavorings and their ingredients are handled (e.g., mixing room) and in adjacent work areas. Also perform checks whenever a process change is made or a problem is suspected.
For processes involving heating of flavorings, keep the temperature as low as possible to minimize emissions of volatile chemicals into the air.
Establish and enforce work practices to limit release of chemicals and dust into the workplace air when flavorings or their ingredients are handled.
- Tightly seal containers with unused or residual amounts of flavorings or their ingredients.
- Maintain good general housekeeping in any areas where flavorings or their ingredients are handled.
- Establish standard procedures for cleaning the workplace, tanks and other containers, and spills.
- Do not use compressed air for cleaning powdered flavorings or ingredients, as this will increase concentrations of airborne particulate.
- Clean up spills of flavorings or their ingredients promptly using procedures and appropriate protective equipment designed to limit exposure.
Use special caution when removing residual chemicals from tanks and other containers with steam or hot water, as this may increase exposure to volatile chemical vapors.
Restrict access to all areas where flavorings are openly handled; only essential workers should enter these areas and only when properly protected (see section on personal protective equipment).

Hello fellow Wikipedians,
I have just added archive links to 2 external links on
Diacetyl. Please take a moment to review
my edit. If necessary, add {{

Diacteyl is produced from citric acid by bacteria, Oenococcus Oeni, during MLF in winemaking.
The primary goal of MLF is to convert malic acid to lactic acid. But, diacetyl is not produced from malic acid. Sources 4,5 used as a reference for this statement make no such claim. 147.69.157.148 ( talk) 03:27, 11 February 2024 (UTC)
