说明

General description

异戊醛是一种短链醛，可通过异戊醇的氧化生成。

异戊醛是一种引诱剂，研究人员通过结合技术得到研究了它与真菌棕榈疫霉的游动孢子 的相互作用 。

Application

以异戊醛为标准品，采用顶空固相微萃取-气相色谱法，通过火焰离子化检测和多变量分析，评价橄榄油的质量。以 5～8 个碳原子为内标，测定了葡萄酒中的芳香羰基化合物。

Binding of isovaleraldehyde, an attractant, to zoospores of the fungus Phytophthora palmivora in relation to zoospore chemotaxis.

J N Cameron et al.

Journal of cell science, 49, 273-281 (1981-06-01)

The interaction of isovaleraldehyde, an attractant, with zoospores of the fungus Phytophthora palmivora was investigated by using binding techniques. The amount of isovaleraldehyde bound diminished with time, an effect that may be related to sensory adaptation. In addition to non-specific

Diversity of L-leucine catabolism in various microorganisms involved in dairy fermentations, and identification of the rate-controlling step in the formation of the potent flavour component 3-methylbutanal.

B A Smit et al.

Applied microbiology and biotechnology, 64(3), 396-402 (2003-11-19)

Various microorganisms, belonging to the genera Lactococcus, Lactobacillus, Streptococcus, Leuconostoc, Bifidobacterium, Propionibacterium, Brevibacterium, Corynebacterium and Arthrobacter, used in dairy fermentations such as cheese making, were analysed for their potential to convert leucine into flavour components, most notably 3-methylbutanal.
