Food: Aroma Compounds, Flavors, Colours and Chemical Changes | Food Chemistry

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 ]. Flavor analysis usually takes one of two forms, sensory or instrumental. Sensory descriptive methods used for testing have been developed that are highly reliable and consistent and obviously identify the human perception of flavor.

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. The major volatile organic compounds VOCs of alcoholic beverages are aldehydes such as acetaldehyde, low-molecular-weight alcohols such as methanol, and higher alcohols Geroyiannaki et al.

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

A simple and fast method was developed for the determination of volatile organic compounds in alcoholic beverages. Eleven volatile organic compounds acetaldehyde, methanol, 2-propanol, tert -butanol, 1-propanol, ethyl acetate, 2-butanol, isobutanol, 1-butanol, 3-methyl-1butanol, and 2-methylbutanol in alcoholic beverages were analyzed with a simple direct-injection method using GC with flame ionization detection. These compounds should be monitored in the QC of production processes because they are detrimental to human health. The method was validated with four types of alcoholic beverages beers, fruit wines, rice wines, and spirits to confirm the versatility of the method. Linearity showed r 2 values from 0. Precision and accuracy showed acceptable results, proving the effectiveness of the method. The developed method was applied to 40 commercial samples representing the four types of alcoholic beverages, and principal component analysis was performed to determine profiles of the volatile organic compounds, depending on the type of alcoholic beverage.

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.

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.
