Attributes such as sour, bitter, nutty, and fruity are direct results of the chemical and biological activities of the compounds, and are often desirable. Some of the volatile compounds that are responsible for characteristic dairy flavors include short-chain fatty acids, ketones, lactones, alcohols, aldehydes, esters, and sulfides. Among these, diacetyl (2,3-butanedione), acetaldehyde, and dimethyl sulfide provide prominent flavors in most dairy products. Nonvolatile compounds such as organic acids (especially lactic and acetic), long-chain fatty acids, amino acids, and peptides are also flavor contributors. An understanding of typical dairy flavor compounds and their origins will enable manufacturers to produce more uniform dairy products with greater consumer acceptance.
