Determination of early stages of rennet-induced aggregation of casein micelles by diffusing wave spectroscopy and rheological measurements

Diffusing wave spectroscopy (DWS) and rheology have been used to study the aggregation of casein micelles dispersions inducedby the addition of rennet, a proteolytic enzyme preparation. Aggregation times measured by DWS and by rheology were in goodagreement. In addition, prior to the onset of aggreg...

Summary:Diffusing wave spectroscopy (DWS) and rheology have been used to study the aggregation of casein micelles dispersions inducedby the addition of rennet, a proteolytic enzyme preparation. Aggregation times measured by DWS and by rheology were in goodagreement. In addition, prior to the onset of aggregation DWS was able to detect the change in the casein micelle mobility due to thecleavage ofj -casein by the enzyme. We believe that, due to its the sensitivity to changes brought in particle size, in addition to beinga non-invasive and a non-intrusive technique, DWS has a potential to be implemented and used in an industrial environment, suchas manufacture of yogurts and cheeses.
