Examining the rapid development in the chemistry and uses of cooling agents. Physiological cooling agents are ubiquitous ingredients in many consumer products, such as chewing gums, toothpastes, mouthwashes, lotions and shampoos. Based on numerous new patents and publications, research and development in the field continues at a fast pace.

New materials and emerging applications. Physiological cooling agents act in a number of ways. In a flavor or fragrance they can be the first impact, leaving a cool sensation on the palate or skin prior to the main aroma being imparted.

Advancements in the Flavor Industry. When I started in the flavor industry, a flavor project basically was a request to compound an artificial flavor. The newly established FEMA or GRAS lists were very limited and initially populated under a grandfather clause. Natural ingredients were limited to citrus, floral and mint oils, as well as other natural botanicals and extractives.

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.

Syntheses and odor characteristics of 1-alkylthio-2-butanethiols, 1-alkylthio-2-butanols and their derivatives. We previously have proposed a presumption that most meaty flavor compounds have a common characteristic structural unit that contains sulfur or oxygen heteroatoms on the adjacent two carbon atoms (one of the heteroatoms should be a sulfur atom).

Nitriles and amides represent two important families of organic compounds containing respectively, a CN or a CONR1R2 moiety. Their chemistries are very much intertwined because either family can serve as a feedstock for the other.

The essential oil from peppermint, Mentha x piperita L., is one of the most widely used oils by the flavor industry for mint flavoring. However, abundant literature and experts’ observations report the varying composition and organoleptic profiles of peppermint oils according to the region of production, climatic variation and harvest date.1-3

In Part 1, “More Fizz for your Buck”, the role of high impact aroma chemicals as character impact materials in foodstuffs was described.1 In that article, a simple 16-segment flavor wheel was used as the theme to link the materials.

The flavor and fragrance industry uses many classes of chemicals, including a number that otherwise are encountered only rarely outside of organic chemistry textbooks. A good example is Schiff bases, named for their discoverer, German chemist Hugo Schiff (1834-1915). A Schiff base, along with by-product water, is formed by reaction of an aldehyde with a primary amine.
