Food Chemistry pp Cite as. German and some other languages do not have an adequate expression for such a broad and comprehensive term. Flavor results from compounds that are divided into two broad classes: Those responsible for taste and those responsible for odors , the latter often designated as aroma substances.

Development of a simultaneous analysis method of volatile compounds by DART MS

Attempts to relate sensory analysis data to specific chemicals such as volatile compounds have been frequent. Often these associations are difficult to interpret or are weak in nature. Although some difficulties may relate to the methods used, the difficulties also result from the complex nature of flavor. For example, there are multiple volatiles responsible for a flavor sensation, combinations of volatiles yield different flavors than those expected from individual compounds, and the differences in perception of volatiles in different matrices. Flavor analysis using a variety of methods has been conducted for many years to help in the development of new products, to understand the nature of existing products, to study shelf-life, and to maintain quality of foods, beverages, products for oral care, and other products such as oral pharmaceuticals and tobacco [ 1 , 2 ].

Associations of Volatile Compounds with Sensory Aroma and Flavor: The Complex Nature of Flavor

Ethanol EtOH is the main risk factor for alcoholic liver disease. However, fermented alcoholic beverages contain not only ethanol but also various volatile compounds. Currently, effects of volatile compounds in ethanol-containing fermented beverages on gut microbiota and host metabolism are largely unclear. To fill this gap, we constructed an 8-week mice model using three types of Baijiu a traditional fermented alcoholic beverage and sterile water and ethanol as controls. The results revealed that three types of Baijiu contain various volatiles, mainly belonging to esters, alcohols, and acids.

A number of volatile organic compounds VOCs including acetone, methyl ethyl ketone, toluene, ethylbenzene, m , p -xylene, styrene, and o - xylene released during food decaying processes were measured from three types of decaying food samples Kimchi KC , fresh fish FF , and salted fish SF. To begin with, all the food samples were contained in a mL throwaway syringe. These samples were then analyzed sequentially for up to a day period. There were strong variations in VOC emission patterns during the food decaying processes between fishes and KC that are characterized most sensitively by such component as styrene. The overall results of this study indicate that concentration levels of the VOCs differed significantly between the food types and with the extent of decaying levels through time.

Evaluation of volatile organic compounds in alcoholic beverages consumed in Korea

They are able to produce and release from the fermentation environment large numbers of volatile organic compounds VOCs. This is the reason for the great interest in the possibility of adapting these microorganisms to fermentation at reduced temperatures. By doing this, it would be possible to obtain better sensory profiles of the final products.

1. Introduction

Metrics details. Volatile organic compounds including acetaldehyde, methanol, and higher alcohols such as 1-propanol and 3-methylbutanol in 75 domestic and imported alcoholic beverages consumed in Korea were investigated and evaluated using a gas chromatograph equipped with a mass spectrometer. The acetaldehyde contents in the studied samples ranged from 0. Only the wine and fruit wine samples contained methanol, at concentrations in the range of 1. The 1-propanol content was highest in whisky, while the 3-methylbutanol content ranged from 4.
