Chemical Properties

Butter starter distillate is a steam distillate of the culture of any or all of the following species of bacteria grown on a medium consisting of skim milk usually fortified with about 0.1% citric acid: Streptococcus lactis, S. cremoris, S. lactis subsp. diactylactis, Leuconostoc citrovorum and L. dextranicum. The ingredients contain more than 98% water, and the remainder is a mixture of a butter-like flavor compound. Diacetyl is the major flavor component, consisting of as much as 80 to 90% of the mixture of organic flavor compounds. Besides diacetyl, starter distillate contains minor amounts of acetaldehyde, ethyl formate, ethyl acetate, acetone, ethyl alcohol, 2-butanone, acetic acid and acetoin.
