[87] Diacetyl reductase

1982
Publisher Summary This chapter describes the assay method, purification, and properties of diacetyl reductase. Diacetyl reductase is assayed by measuring the decrease in absorbance at 340 nm caused by nicotinamide adenine dinucleotide dehydrogenase (NADH) oxidation during diacetyl reduction to acetoin.

OLFACTORY RESPONSIVENESS TO DIACETYL

Journal of Sensory Studies, 1994
ABSTRACTOdor thresholds in the headspace over aqueous solutions of diacetyl (butane‐2,3‐dione) were measured in quadruplicate by a forced‐choice procedure in 53 individuals. Mean individual thresholds varied over a factor of 256, with the group average at .005 μg/ml. Thresholds showed a modest negative correlation with suprathreshold intensity ratings.

Diacetyl: Occurrence, Analysis, and Toxicity

Journal of Agricultural and Food Chemistry, 2014
Diacetyl possesses a butter-like flavor and has been widely used as a flavoring agent. It forms from sugars and lipids via various bacteria and heat treatment in various foods and beverages, such as milk. The toxicity of diacetyl, especially when inhaled, has recently attracted the attention not only of consumers but also of regulatory agencies.

The vibrational spectra of diacetyl and diacetyl‐d₆

Zeitschrift für Elektrochemie, Berichte der Bunsengesellschaft für physikalische Chemie, 1960
AbstractThe infrared and Raman spectra of diacetyl and diacetyl‐d6 have been measured, and vibrational assignments are proposed for the fundamental bands and for several infrared active combination bands. The Raman spectrum of diacetyl‐d6 has not hitherto been determined, and only a few of the stronger Raman bands of diacetyl have been reported in ...
