Abstract

To unambiguously identify their structures and to evaluate their organoleptic properties, several constitutional und configurational isomers of dialkyl-tetrathianes and dialkyl-pentathiepanes were synthesized by two different synthetic protocols, and separated by preparative gas chromatography. Raman and NMR spectroscopy were used to differentiate between the constitutional 3,6-dialkyl-1,2,4,5-tetrathiane and the 4,6-dialkyl-1,2,3,5-tetrathiane isomers. Furthermore, cis- and trans-isomers of 3,6-dialkyl-1,2,4,5-tetrathianes were distinguished by temperature-dependent NMR experiments. Static, quantum-chemical simulations of the NMR spectra for these cis- and trans-isomers were calculated in the gas layer in order to confirm our experimental assignments. In addition, the assignment of 4,7-alkyl-1,2,3,5,6-pentathiepanes were deducted from their Raman spectra. Dialkyl-tetrathianes and dialkyl-pentathiepanes are interesting components to be used in flavor applications due to their unique olfactory impact and facets.

Abstract

Cyclic polysulfides such as trithiolanes, tetrathianes and their derivatives are found in natural sources like archaea, mushrooms and vegetables. They gained interest for research and industrial applications because of their pronounced flavors and biological activity. This study compares Raman spectra of reference compounds and cyclic polysulfides which were synthesized in-house and separated by preparative gas chromatography. The data show that the positions of the Raman bands due to S S stretching vibrations in the wavenumber region from 550 to 450 cm −1 can determine the relative stereochemistry of 2,5-dialkyl trithiolanes and 4,6-dialkyl tetrathianes. Configurational cis isomers were distinguished from their corresponding trans isomers. In addition, 4,6-dialkyl-1,2,4,5-tetrathiane with disulfide bonds were distinguished from the constitutive isomer 3,6-dialkyl-1,2,3,5-tetrathiane with trisulfide bonds.

Abstract

Model studies have been performed with individual citrus related aroma compounds such as citral, α-terpineol, α-terpinene, and others, in order to de-couple the complexity of citrus flavors. Degradation pathways and transformation rates have been determined for the most relevant compounds leading to the most prominent off-note compound p-methyl acetophenone. Citral is one of the main precursors. Catechins (flavan-3-ols) are often used as antioxidants for stabilization of flavor mixtures. The reactivity of catechins towards aldehydes is underestimated. In our study, we demonstrate the formation of covalent catechin–citral adducts – a reaction that might influence the aroma stability of citrus flavors in the presence of catechins. As a result, the freshness of citrus flavors and stability of key aroma-active substances can be improved, on the result of this study.

Abstract

Knowledge of the difference in character and intensity of organoleptically important enantiomeric flavor and fragrance components has initiated the development of new analytical and preparative methods for the separation of optical isomers. In recent years, progress in the area of chirospecific analysis has been especially achieved by the development of modified cyclodextrins as a new type of chiral stationary phase. The state of the art in research on inclusion gas chromatography for separating flavor and fragrance substances is presented. Furthermore, this review reports on new results and recent research developments in enantioselective GC analysis.

Abstract

This study describes the identification of six allyl esters in a garlic cheese preparation and in a commercial cream cheese. The extracts were prepared by liquid/liquid extraction and concentrated by the SAFE process. The identification of the allyl esters of acetic, butyric, hexanoic, heptanoic, octanoic, and decanoic acids is based on the correlation of their mass spectrometric data and chromatographic retention time data obtained from the extracts with those of authentic standards. In addition to the gas chromatography (GC)/mass spectrometry analysis, the flavor ingredients were characterized by GC sniffing by a trained flavorist. Some of the esters were isolated by preparative GC.

Abstract

In the past flavor research and the development of new flavorings were constantly driven by the interaction of flavor analysis, structure elucidation, and chemical synthesis accompanied by sensory. Highly potent flavor compounds were identified in numerous food products and helped to establish a powerful toolbox for flavorists. Nowadays we experience the merging of various scientific disciplines, for example medicine, biology, chemistry, and various technologies in the field of flavor research, which shows direct impact on our understanding of flavors. At the same time modern life has profoundly changed our eating habits. This situation generates new challenges for product development teams, which represent all facets of technologies. This paper will illustrate different examples for the evolution of product-oriented flavor research and future trends.

Abstract

In culinary preparations cooked, roasted and fried Allium products play a major role in the taste and the aroma of the final product. In this study the correlation of various culinary preparation techniques such as cooking and frying and the resulting differences in the flavour chemistry (volatiles and non-volatiles) are demonstrated. Different preparation techniques performed on shallots, garlic and/or scallions influence the profile of volatiles and non-volatiles in culinary preparations significantly.
