Acetoin is an important physiological metabolite excreted by many microorganisms. The excretion of acetoin, which can be diagnosed by the Voges Proskauer test and serves as a microbial classification marker, has its vital physiological meanings to these microbes mainly including avoiding acification …

2020年12月15日 · National Toxicology Program (NTP): Chemical Information Review Document for Artificial Butter Flavoring and Constituents Diacetyl [CAS No. 431-03-8] and Acetoin [CAS No. 513-86-0] . January 2007.

Acetoin, 3-hydroxyl,2-butanone, is extensively used as a flavor additive in food products. This volatile compound is produced by the dairy bacterium Lactococcus lactis when aerobic respiration is activated by haem addition, and comprises ∼70% of carbohydrate degradation products.

Acetoin, a high-value-added bio-based platform chemical, is widely used in foods, cosmetics, agriculture, and the chemical industry. It is an important precursor for the synthesis of: 2,3-butanediol, liquid hydrocarbon fuels and heterocyclic compounds.

Acetoin, also known as 3-hydroxybutanone or acetyl methyl carbinol, is a colorless or pale yellow to green-yellow liquid with a pleasant buttery odor. It is a versatile compound used widely in several applications, owing to its organoleptic properties and …

2022年2月21日 · Acetoin (AC) is an important platform bulk chemical with versatile applications. It exists in two stereoisomeric forms: (3R)-AC and (3S)-AC. Both stereoisomers could be potentially applied in the pharmaceutical industry, agriculture, and in optically active α-hydroxyketone derivative synthesis.
