Thermal denaturation and
aggregation of ß-LB
The heat denaturation of milk proteins has an effect on the functional properties of milk for cheese making. Aggregation of denatured ß-lactoglobulin (ß-LG) and k-casein (k-CN) creates a loose, high moisture, low quality gel. Currently no easy technique is available for quantifying ß-LG denaturation and aggregation with k-CN in milk.
It is hypothesized that the optical response difference between heat damaged and native milk serves as a marker of the linkage between ß-LG and k-CN. This optical method of detection could potentially be installed in- or off- line and would result in a re-duction of enzymes and cultures used on milk with altered proteins as well as a more consistent product. Most importantly, milk having a high level of denatured proteins could be diverted to other purposes such as yogurt manufacturing.
