Abstract excerpt
A simple, rapid bioluminescence test (BT) for the determination of lipid oxidation is described. The test utilizes an aldehyde-requiring dark mutant of Vibrio harveyi (M42) that emits light in the presence of long chain (C8-C16) aliphatic aldehydes. The procedure consists of treating the oil or fat with CO2+ ion in ethanolic medium at alkaline pH. This treatment facilitates the decomposition of the hydroperoxides...
