Vapor Pressure and Stability of Allyl Isothiocyanate

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi), 1994
Allyl isothiocyanate, a main flavoring constituent of wasabi and mustard, is known to have strong antimicrobial activity. A study was made of the vapor pressure changes and the stability under various conditions of this substance as part of a research program aimed at producing a preparation which would allow exploitation of its antibacterial effect ...

Otto Billeter or How the Oldest [3,3]-Sigmatropic Rearrangement Went to Neuchâtel Otto Billeter oder wie die älteste [3,3]-sigmatrope Umlagerung nach Neuenburg kam: Teil1

CHIMIA, 1999
A historical study on the early chemistry of organic isothiocyanates (mustard oil) and thiocyanates (rhodanides) is presented. The isomeric structures of these compounds were settled by the famous investigations of August Wilhelm Hofmann ...

Effect of high-pressure processing on the bioactive compounds of white and Ethiopian mustard plant-based ingredients: Spotlight on glucosinolate content and the bioaccessibility of isothiocyanates and selenium

NFS Journal
This work aims to investigate the effects of high pressure processing (HPP) on the initial content of the main glucosinolates (glucotropaeolin and sinigrin), myrosinase activity, and bioaccessibility of isothiocyanates and selenium in shoots and leaves ...

Decomposition of Allyl Isothiocyanate in Aqueous Solution

Agricultural and Biological Chemistry, 1969
Allyl isothiocyanate was gradually decomposed in aqueous solution to produce a garlic like odor. The decomposition of this isothiocyanate was not based on hydrolysis of R-NCS as in the case of p-hydroxybenzyl isothiocyanate, but the addition reaction on –N=C=S. Four substances formed with the decomposition of the isothiocyanate were isolated, and their

Experimental and theoretical studies on the isomerization of allyl thiocyanate to allyl isothiocyanate

Heteroatom Chemistry, 1997
The mechanism of isomerization of allyl thiocyanate to allyl isothiocyanate has been investigated both experimentally and theoretically. The kinetic study indicates that the reaction is unimolecular and is not ionic. The entropy of activation suggests strongly that the mechanism involves a cyclic transition state. The rate of reaction was retarded to a

The Reaction of Allyl Isothiocyanate with Hydroxyl/Water and β-Cyclodextrin Using Ultraviolet Spectrometry

Food Technology and Biotechnology, 2006
The reaction of allyl isothiocyanate (AITC) with hydroxyl/water and β-cyclodextrin (β-CD) in different acidic-alkaline media has been investigated by ultraviolet spectrometry. The kinetic parameters of the reaction were measured.
