Product Description | 2,3-Butanedione, a volatile compound, is a product of citrate metabolism that is generally produced by certain bacteria including Lactococcus lactis ssp. diacetylactis and Leuconostoc citrovorum. It has a typical buttery flavor and is commonly found in fermented dairy products, such as sour cream, yogurt and cottage cheese. Inactivates aminopeptidase-N. Cyclocondensation with amines has been used to form triazine and pteridine ring systems. Also used as a precursor to α-diones. |
