Flavor control in dairy products and beer with special reference to diacetyl

Creator:: Pack, Moo Young
Abstract:: The stability of diacetyl in fermented milk and the removal of diacetyl from beer were studied. A convenient method for the determination of diacetyl in beer, established by Owades and Jakovac, was modified and applied for flavor analyses of dairy products. Through this method, diacetyl in 12 samples could be...
