Rapid Quantitative Method for Determination of Acetaldehyde in Lactic Starter Cultures

Abstract

The 3-methyl-2-benzothiazolone hydrazone test was adapted for the spectro-photometric determination of acetaldehyde in lactic starter cultures. The method was modified, so that it utilized the same equipment as a recently reported method for determination of diacetyl in starter cultures. Reaction conditions, uses, and limitations of the method are discussed. The procedure was applied in conjunction with diacetyl measurements in studying single- and mixed-strain lactic starter cultures. © 1965, American Dairy Science Association. All rights reserved.
