Progress in Essential Oils: Sweet Fennel Oil and Extract

In this column, Brian M. Lawrence reviews the composition of sweet fennel oil and extract as found by various researchers. For example, a commercial sample of sweet fennel oil was screened for its anti-platelet activity by Tognolini et al. (2006) and Guerini et al. (2006) using GC-FID and GC/MS. Results are reported herein.

Essential Oils and Microwave Extracts of Cultivated Plants

We have used these two methods to treat different cultivated plants: five Umbelliferae, one Compositae and seven Labiatae. There is a double purpose for this approach. First, we want to determine the advantages and disadvantages of this technique in terms of research. Secondly, we intend to make appropriate comparisons between microwave extracts and essential oils coming from the aerial part of these plants.

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.

Most of the vanillin in the market comes from chemical synthesis, with approximately 85% produced from Guaiacol (petrochemical products), while the rest are from lignin and eugenol.

A New Method of Separation of Citral from Lemongrass Oil

Although many methods are known for the separation of citral from lemongrass (Cymbopogen flexuosus) oil, like fractional distillation, adduct formation and regeneration, the purity and the yield of citral as separated are not satisfactory. A new method for separation of citral in pure form and in near quantitative yield uses the column chromatographic technique. This method may also be adapted for large scale separation of citral and hence can be of commercial importance.

Authentication of Natural Peppermint Oil

This article explores the application of carbon-14 testing as a method to authenticate naturally sourced peppermint oil and screen for adulteration.

Stability of Citral-Containing and Citralless Lemon Oils in Flavor Emulsions and Beverages

The storage stability of lemon oil treated to remove citral has not been reported. This investigation was conducted to compare the stabilities of citral-containing and citralless lemon emulsions (EC and ECL) and beverages (BC and BCL) during storage at different temperatures by both gas chromatographic and sensory analyses.

Thoughts On Aroma Chem Essential cals for Oils and Flavors and Fragrances

The ultimate goal of the flavor and fragrance industry is to improve the quality of life through production and focused application of flavors and fragrances. In order to do this, one must first understand the basic role of smell and taste in life. This means investing in research into the science of smell and taste
