A Closer Look at Garlic Oil: Verifying Naturality

This case study takes a look at the challenges on the production side of the garlic oil industry, which has necessitated increased vigilance in verifying the real natural content of this product downstream.

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.

Investigating New Essential Oils: Rationale, Results and Limitations

Research in new essential oils may provide benefits (missing aroma notes, new sources of isolates, new chiral compounds), but it must reassert its originality and vigor and it must recognize the constraints of economics and regulations.

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.

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.

Analysis of Encapsulated Orange Peel Oil

The toluene distillation method is suggested for the routine determination of moisture in spray dried citrus oils. The technique is rapid and due to large sample size, has minimal sampling error, requires minimal equipment and can be performed by an individual with little technical training.

Pattern Recognition Methods for Discrimination of Essential Oils (Rose Oils) by Their Gas Chromatograms

It is possible to distinguish between essential oils of the same type and their mixtures by analysing their gas chromatograms using a pattern recognition method.
