Can anyone explain why bad bread can sometimes smell like nail polish remover or acetone?

 

I have a rather important complaint on this matter and cannot find the science to explain it!

 

Thank's!

This problem is nearly always caused by the wild yeast, endomycopsis. This yeast is found in nature and is carried into the plant by air currents. The yeast converts starch into acetone, which is the odor detected in the bread. The yeast can best be eliminated by washing the equipment with vinegar.

If you don't do so already, I'd suggest getting some PDA plates and do some air sampling in your post bake areas. You may have high counts of yeast in the air.

sounds like Butyric notes associated with pineapple and nail  vanish notes linked to rope and bacillus formation.

Hello, I´ve been asked to consult on this same issue in Buenos Aires, Argentinas, bigest factory at that time (loong time ago). It was a fermentation or Pichia membranifaciens. It was on the environment - and the packaging area had several structural issues, where ambient cross contamination could be a cause,

Hope this helps you!
