| Abstract: | "Lipid oxidation is a major contributor to the deterioration of the sensory quality of fat-containing dairy powders. Hydroperoxides are the primary oxidation products from unsaturated fatty-acids that readily yield a complex mixture of volatile organic compounds that can adversely impact product quality and shelf life. Headspace solid-phase microextraction gas-chromatography mass-spectrometry was chosen to quantify thirteen lipid oxidation compounds in whole milk powder encompassing a range of volatilities and chemical classes. A central composite rotatable design (CCD, alpha?ª+=?ª+1.1) based on a 2(3) factorial table was used with response surface methodology to optimize the HS-SPME parameters; determined at; 45?ª+min extraction time and 43?ª+ degrees C extraction temperature. The significant model terms were found to be extraction temperature (p?ª+ |
