Carvone

An aroma chemical profile: carvone. The basic organic chemical structure of the carvones is similar to that of the menthols and menthones. Thus, it is not surprising to discover a distinct organoleptic impression for each optical antipode. However, the organoleptic impressions are not similar to menthol or menthone, nor do the carvones display the cooling effect of menthol.

Synthetic Routes to Carvone

Methods leading to (–)-, (+)-, and (±)-carvone have been reviewed, The technical production of (–)-carvone is based on the widely available (+)-limonene; the most favored route is that epitomized in Chart 1. Though the steps involved are simple, their exploitation is a wellguarded secret, There is no similar commercialscale production of (+)-carvone because the basic materials for its synthesis are not as readily available. However, sooner or later the rising demand for this ketone will ensure that it, too, will be produced synthetically.

An Aroma Chemical Profile: Menthol

L-menthol can be described as unique for its cooling sensation on the skin and mucous membranes. Although other materials are known to display this cooling effect, almost all of them are derivatives of l-menthol.

Comparative Investigations of the Essential Oil and Volatiles of Spearmint

The objective of this work is to identify the fragrance compounds of this oil and its SPME-headspace by means of gas chromatographic- spectroscopic (GC and GC/MS using different polar and chiral phases) and olfactoric methods (GC-sniffing technique and olfactory correlations) to find out the importance of each single constituent with their specific odor attributes, responsible for the characteristic and pleasant spearmint aroma for the first time.

Spray Drying of Food Flavors. Ill. Optimum Infeed Concentrations for the Retention of Artificial Flavors

The practical aspects of this work are that each flavor encapsulating material will exhibit an optimum concentration for flavor retention. The optimum concentrations determined in our study may not necessarily be the same as in a production facility. This would have to be determined using actual production equipment. If the retention is limited by the ability to atomize, this factor is equipment dependent. It does appear worthwhile to make this determination, however.

Getting ahead: Technology and Innovation

Applying the lead user process to identify and implement new F&F technologies. Technology and innovation initiatives at flavor companies often are misunderstood or, worse, mismanaged because of poor understanding of the relationships between technology, innovation and the company’s business engine. This article will attempt to shed some much-needed light on the connections between these three variables, as well as the challenges in reaching a harmonious balance among them.
