Fermentation temperature and wort composition influence on diacetyl and 2, 3-pentanedione contents in beer [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2005
Diacetyl and 2,3-pentanedione are important constituents of beer sensory properties. A new GC/MS method for diacetyl and 2,3-pentanedione content determination was developed.

Development of Lactococcus lactis Biosensors for Detection of Diacetyl [PDF]

open access: yesFrontiers in Microbiology, 2020
Some secondary metabolites of fermentative bacteria are desired compounds for the food industry. Examples of these compounds are diacetyl and acetaldehyde, which are produced by species of the lactic acid bacteria (LAB) family.

Effects of diacetyl-liensinine on electrophysiology in rabbit ventricular myocytes

open access: yesBMC Pharmacology and Toxicology, 2017
Background Diacetyl-liensinine is a chemosynthetic derivative of liensinine, extracted from the seed embryo of Nelumbo nucifera Gaertn, in China. It has been found to have extensive anti- arrhythmic actions.

A Fluorescent Probe for Diacetyl Detection [PDF]

open access: yesJournal of Fluorescence, 2008
A water-soluble fluorescent probe, rhodamine B hydrazide (RBH), was prepared and its properties for recognition of diacetyl were studied. The method employs the reaction of diacetyl with RBH, a colorless and non-fluorescent rhodamine B spiro form derivative to give a pink-colored fluorescent substance.

Synthesis of 1,2-phenylenediamine capturing molecule for the detection of diacetyl

open access: yesData in Brief, 2017
Here we describe the design of 1,2-phenylenediamine capturing molecule and the synthesis steps necessary for its preparation. The designed 1,2-phenylenediamine derivative is able to capture diacetyl in solution, as shown by ESIMS, forming a chemical ...

Diacetyl as Acetyl Donor [PDF]

open access: yesActa Medicinae Okayama, 1956
Diacetyl can serve as an acetyl donor for the forlnation of citrate and the acetylation of sulfanilamide in the dog heart homogenate. Diphosphothiamine and coenzyme A are essential for these reactions.

Effect of Working Atmospheres on the Detection of Diacetyl by Resistive SnO2 Sensor

open access: yesApplied Sciences, 2021
Nanostructured metal oxide semiconductors (MOS) are considered proper candidates to develop low cost and real-time resistive sensors able to detect volatile organic compounds (VOCs), e.g., diacetyl.

Diacetyl Inhibits the Browning of Fresh-Cut Stem Lettuce by Regulating the Metabolism of Phenylpropane and Antioxidant Ability

open access: yesFoods, 2023
Enzymatic browning is the main quality issue of fresh-cut stem lettuce (Lactuca sativa L. var. angustana Irish). In this research, the effect of diacetyl on the browning and browning-related mechanisms of fresh-cut stem lettuce was explored.

Diacetyl strategy for synthesis of NHAc containing glycans: enhancing glycosylation reactivity via diacetyl imide protection

open access: yesFrontiers in Chemistry, 2023
The presence of NHAc groups in the substrates (both glycosyl donors and acceptors) significantly reduced the reactivity of glycosylation. This decrease was attributed to the NHAc groups forming intermolecular hydrogen bonds by the NHAc groups, thereby ...
