The ready-to-use BAT Culture Media and the enzymatic Guaiacol Detection Kit allow guaiacol-producing Alicyclobacilli to be detected quickly and reliably in fruit juice and beverages containing juice.. This simple detection complies with IFU – International Fruit Union Method No. 12A: “Method on Detection of taint producing Alicyclobacillus in Fruit Juices”.

One of the best places to survey its sloppy creativity is inside your nose. When you smell a lily or a cigar or a jug of spoiled Chlorinated guaiacol derivatives are found in waste water of pulp mills using chlorine in the bleaching process of wood pulp. They can also be detected in fish tissue, possibly causing off-odors. To date, there is no systematic investigation on the odor properties of halogenated guaiacol derivatives. To close this gap, odor thresholds in air and odor qualities of 14 compounds were determined Substance identity Substance identity. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases.

Guaiacol (/ ˈ ɡ w aɪ ə k ɒ l /) is a naturally-occurring organic compound with the formula C 6 H 4 (OH)(OCH 3). Although it is biosynthesized by a variety of organisms, [3] this aromatic oil is usually derived from guaiacum or wood creosote .

The brain’s olfactory bulb – the first port of call Influence of the chemical structure on the odor qualities and odor thresholds of guaiacol-derived odorants, Part 1: Alkylated, alkenylated and methoxylated derivatives. Guaiacol is a compound used as expectorant. In Mexico City, this product is being illegally used for aesthetic treatment with fatal results. The aim of this study is to confirm the lethal toxicity documented in humans. Male Swiss Webster mice (CFW) 30-45g were employed.

Ethyl vanillin (structure shown in the middle, above), which does not occur naturally, has a much stronger vanilla smell than its methyl analogue, vanillin itself. The odour threshold of ethyl vanillin is given as 0.000007 mg/m 3 of air, in comparison for a value for vanillin itself in the range 0.005 - 0.000001 mg/m 3 of air.

We found that guaiacol is preferentially associated with ethanol, smell of the whisky. Of note, it has recently been shown that surface-active molecules are depleted from the .

Some Alicyclobacillus strains can produce guaiacol, which causes a strong off-flavour in juices and beverages containing fruit juice. This flavour has a chemical smell similar comparable to disinfectant. According to the latest scientific expertise, A. acidoterrestris, A. acidiphilus und A. herbarius have the potential to produce off-flavours. Overall, the investigated compounds elicited smells that are characteristic for guaiacol, namely smoky, sweet, vanilla-like, but also medicinal and plaster-like. Their odor thresholds in air were, however, very low, ranging from 0.00072 to 23 ng/Lair. But now that I've been smelling it so much, I kinda like it :D lol.
