Environmental factors, such as temperature, can either increase or decrease lipid oxidation rates depending on the system. For instance, in most foods a 10ºC increase in temperature corresponds to approximately a doubling in the rate of oxidation (Matthäus 2010).Elevated temperatures can increase lipid oxidation rates by promoting …

WebLipid oxidation is one of the most important mechanisms for breaking down food. It is a severe defect that matters in food preservation and it can offer food an off-flavor and odor. Lipids are common ingredients in food, especially in meat, dairy and fried products. WebThe composition and the structure of lipids alters the rate and pathways of oxidation. Research will define food structures that alter oxidation. Food emulsion systems will be assembled from lipid, protein and carbohydrate polymers using dispersion methods including sonic disruption, physical disruption, membrane filtration and centrifugation.
