Flavor Bites: Para-mentha-8-thiol-3-one acetate

Though similar to para-mentha-8-thiol-3-one in odor profile, para-mentha-8-thiol-3-one acetate is more heat stable and is less prone to H2S loss on storage.

Identification of 9-Decen-2-one in Pineapple

Analysis of natural occurrence and application in fragrances and flavors.

Analysis of Glycosidically Bound 2,5-Dimethyl-4-hydroxy-3 (2H)-furanone in Pineapple

This paper reports evidence of the presence of glycosidically bound DMHF in pineapple. In the last few years the analysis of flavor precursors and intermediates, especially glycosides in fruits, has received increasing interest and attention (Strauss, et al., 1986; Schwab and Schreier, 1988).

Chemistry and application

Orange blossom

Orange blossoms are the flowers from the bitter orange tree, Citrus Aurantium Linnaeus. Originating in China, the bitter orange tree was probably introduced to southern France somewhere between the tenth and eleventh centuries AD byt the conquering Arabs. It remained the only orange known to Europeans for about five centuries. Since the fruit of this tree is so unpalatable (though more sour than bitter from this author's first hand experience) it is no wonder that products for fragrances were developed.

Bitter Orange Obsession

Exploring the rich range of traditional and leading-edge ingredients derived from this iconic tree

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.

Natural Isolates from Seville Bitter Orange Tree

Bitter orange peel oil is a usefd ingredient for flavorists became of its tenacity. Because of the increase in citrus style scents, the peel oil has gained popularity in the fragrance field, for instance, in men’s line products such as aftershave and body lotions. It serves well in perfumes, toilet waters and cosmetics.

Current Investigations on Orange Peel Oil Fractionation

The main objective of this work is to present our experimental fi ndings concerning the deterpenation of orange peel oil using a vacuum distillation column and some insights into the use of SCFCO2 in a packed high-pressure extraction column.

Natural Aroma Chemicals for Oranges and Other Botanical Sources

In this article, I will focus on the production of aroma chemicals from orange. But I will also mention other essential oils that are sources of aroma chemicals.

Counter Current Deterpenation of Cold Pressed Sweet Orange Peel Oil

As with all citrus concentrates made by contacting oil with alcohol, the counter current deterpenated orange oil contains acetal compounds formed from the chemical condensation of aldehydes and alcohol. In flavor applications, they tend to have a “smoothing and fixing effect” in product, which is normally considered as advantageous,

The volume of orange oil, terpenes, and d-limonene produced is directly related to the quantity of oranges processed for orange juice.

The quality of Valencia orange peel oil as related to rootstock

The aldehyde and ester content of citrus oils have long been considered important indicators of flavor and aroma, and rootstocks can have an influence on this important quality of an orange oil. However, the limited amount of data accumulated regarding the influence of rootstock on oil quality and yield indicate the need for further study and research to include other varieties and rootstocks of citrus.

Differences in Chemical and Sensory Properties of Orange Flower and Rose Oils Obtained from Hydrodistillation and from Supercritical C02 Extraction

In this article we will identify some characteristic and essential constituents of bitter orange flowers (Citrus aurantium L., ssp. armzra Engl.) from Spain, Tunisia and Morocco, and roses (Rosa damascena Mill.) from Bulgaria and Turkey, and we will discuss how the consitutents differ depending on whether the oils were isolated by hydrodistillation or by supercritical fluid carbon dioxide extraction of the concretes. hydrodistillatio norbysupercriticai fluid carbon dioxide extraction of the concretes.

Inside Flavors: Real Time Volatile Flavor Release Monitoring and its Flavor/Food Application Using Proton Transfer Reaction Mass Spectrometry

Understanding how aroma compounds interact with and are released from simple and complex foods. Flavors and fragrances usually are complex mixtures of molecules with different physical properties, including volatility, fat solubility and sensorial characteristics, covering a wide spectrum of threshold values. They are usually present in natural extracts or final products at levels in the order of ppb to ppm.
