Milk protein concentrates (MPC) are widespread food ingredients, due to their high protein-to-solids ratio, nutritional value, and technological properties, which can be tailored various end uses. Interest has been given modifying such ingredients through enzymatic cross-linking by microbial transglutaminase. However, no systematic studies on the kinetics of casein micelles at different concent...

Cheese production is relied upon the action of rennet (a mixture of chymosin and pepsin) onto casein micelles of milk. For the first time, the monitoring of this interaction with electrochemical impedance spectroscopy (EIS) was used to develop a faradic impedimetric biosensor for the assessment of the clotting activity of rennet, using hexacyanoferrate(II)/(III) couple as a redox probe. Gold el...

The effect of ultrafiltration and diafiltration on the distribution of the calcium phosphate clusters of the casein micelle was investigated using Small Angle Neutron Scattering (SANS). In the case of ultrafiltration, fresh skim milk was subjected to concentration using membrane filtration up to 5× its original volume, the retentate was rediluted with its corresponding serum and subsequently di...
