“…Values obtained for three ester compounds were within expected ranges [16,17]. Isoamyl acetate is known to be produced in higher amounts by Hefeweizen and Belgian yeast, while other ales are characterized by higher ethyl caprylate and ethyl caprate concentrations [18]. In this study, the two Belgian style beers (samples 1 and 9) did show higher isoamyl acetate values.…”

Chemical analysis of the organic components in beer has applications to quality control, authenticity and improvements to the flavor characteristics and brewing process. This study aims to show the complementary nature of two instrumental techniques which, in combination, can identify and quantify a number of organic components in a beer sample. Nuclear Magnetic Resonance (NMR) was used to provide concentrations of 26 different organic compounds including alcohols, organic acids, carbohydrates, and amino acids. Calorie content was also estimated for the samples. NMR data for ethanol concentrations were validated by comparison to a Fourier Transform Infrared Spectrometry (FTIR) method. Headspace Solid-Phase Microextraction (SPME) Gas Chromatography Mass Spectrometry (GCMS) was used to identify a range of volatile compounds such as alcohols, esters and hop-derived aroma compounds. A simple and inexpensive conversion of a Gas Chromatography Flame Ionization Detector (GC FID) instrument to allow the use of Solid-Phase Microextraction was found to be useful for the quantification of volatile esters.

“…This observation was confirmed by previous studies on land snails of various species [18][19][20][21]. It has been found, that brand of beer, hence its various chemical composition [22], may influence on the attractiveness of this drink for slugs A. lusitanicus. Analogous reactions of snails on beers of different brands were also noted by Dankowska [18].…”

“…Those differences could be a result of changing conditions during the experiment, especially in the case of field experiments. Both ambient temperature [22,23], chemical composition [22,[24][25][26] and a colour of the drink [23,27], may have in fact a significant influence on the rate of decomposition of beer.…”

Abstract:In 2012-2013 a series of laboratory and field experiments were carried out to check out, if beers can be used as olfactory attractants in the fight against harmful slugs Arion lusitanicus. Six brands of lager beer were used for olfactory analysis (Goolman Premium, Harnas Jasne Pełne, Tatra Mocne, Kasztelan Niepasteryzowane, Lezajsk Niepasteryzowane, Wojak Jasny Pelny). During laboratory and field tests it was evidenced that beers of all types were more attractive for slugs than water.

“…For example, Vanderhaegen et al 22 analyzed different beer types, and found high contents of isoamyl acetate and ethyl hexanoate (caproate). Liu et al 23 applied a sol-gel fiber based on 3-(trimethoxysilyl)propyl metacrilate to a beer headspace analysis, and found the above-cited esthers as well as acetic acid, caproic acid and isoamyl alcohol.…”

The preparation and applicability of solid phase microextraction (SPME) fibers coated with a sol-gel organically modified silica based on 3-aminopropyltrimethoxysilane and polydimethylsiloxane (APTMS/PDMS) are described here. Micrographs of the coated fibers revealed a rugous surface; the thickness of the coating was estimated to be less than 30 mm. The APTMS/PDMS fibers were tested with synthetic samples and compared to commercial fibers for headspace SPME analysis of beer. Extraction and desorption using the APTMS/PDMS fibers were faster, which is typical for sol-gel SPME fibers. For polar and semi-polar compounds on beer headspace, the extraction efficiencies of the APTMS/PDMS fiber were superior to those of conventional fibers. The APTMS/PDMS fiber was found to be capable of extracting a broad range of analytes, including highly polar acidic species such as organic acids.
