Organoleptic Characteristics of Flavor Materials

Orange essence oil, hexanal, isoamyl-2-methylbutyrate, 2-octen-4-one and more.

Cinnamic Aldehyde

The high levels of cinnamic aldehyde present in cassia and cinnamon spice, their oils and oleoresins have so colored their impressions as to have created a blur both organoleptically and practically in our industry.

Aldehyde C-11 Undecylenic

The answer to the age-old question as to the closeness of the aldehydes’ organoleptic profile to that of the acetal or nitrile derivative is clear sometimes it is close and sometimes it isn’t. All aliphatic aldehydes and their corresponding nitrile are closest in organoleptic profile at the C–11 molecule.

Aldehyde C-11

Aroma chemical profile, aldehyde C-11. The terms aldehyde and aldehydic have become an intregal part of the vocabulary of the fragrance and flavor industry.

Aldehyde Generators for Flavors

The quest to deliver unstable aldehydes to food systems by the use of generators is being realized. With the proper generator, flavors can be created for use under conditions traditionally unfavorable to aldehydes, As in other derived systems it appears best to employ nature as a model and to design generators in the same way that nature produces flavors.

Kesom Oil—A Natural Source of Aliphatic Aldehydes

The recent investigation of the plant habitats and the chemical analysis of the essential oils obtained from the leaves and stems provided some new findings that could prove highly useful to the flavour and fragrance industry. In this report the habitats of Polygonum minus Huds. and the chemical composition of leaf and stem oils are presented, and the possible relevance of Kesom oil as a new product is discussed.

Research article: Biotransformation of Unsaturated Aliphatic Aldehydes Using Baker’s Yeast

Actively fermenting baker’s yeast (Saccharomyces cerevisiae) not only converts aliphatic aldehydes to the corresponding alcohols, but also may reduce certain carbon-carbon double bonds in the same molecule. Furthermore, an in situ acyloin condensation reaction occurs; this bioconversion reaction gives rise to relatively good yields of unsaturated 2,3-diols, which have two carbon atoms more than the corresponding aliphatic aldehyde used as substrate. Baker’s yeast has been used as a reagent in organic synthesis since the beginning of the 20th century, when fundamental studies were initiated on the mechanism of formation of fusel alcohols from the corresponding l-amino acids during the formation of ethanol.
