Oxidative reactions during beer pasterization were studied using chemiluminescence (CL) and electron spin resonance (ESR) analyses. the CL production of beer was acclerated by pasteurization and the maximum CL intensity appeared sooner than that in n

An analytical method was based on the aldehyde-bisulfite (separated by HPLC) reaction with o-phthalaldehyde in the presence of ammonium acetate, producing a fluorescent compound. Detection limits of alkanal-bisulfite (from formaldehyde- to octylaldeh

The mechanism of bisulfite adduct contribution to stability of beer quality was studied. Formaldehyde- and acetaldehyde-bisulffite adducts had only a poor oxidation potential around 0.93 V, which is the oxidation potential of free sulfite so that the

Linoleic and linolenic acid hydroperoxides in malt, mash, or wort were determined with high sensitivity and high selectivity by the chemiluminescence-high performance liquid chromatography (CL-HPLC) method using isoluminol-microperoxidase solution as

To clarify the lipid oxidation mechanism during wort production, the production of hydroperoxides during mashing was studied using a chemiluminescence-HPLC method. Free linoleic and linolenic acids increased during mashing and their rates of increase
