In most cheese varieties β-casein is more resistant to proteolysis than, αs-casein. This greater relative resistance has been ascribed to such lactors as cheese moisture content, aw, pH and proteins, minerals, calcium and ...

PAGE patterns of the ripened Manchego cheese caseins show that alfas-casein is more extensively degraded than beta-casein. Hydrolysis of alfas-casein gives rise to two first degradation main products of higher relative ...

The enzymic hydrolisis in Serena cheese of the αs-casein, and not that of β-ca¬sein, is concentration-dependent, being lesser as the non fatty components concen¬tration increase in the cheese polar phase. The main factor ...

In commenrciai Manchego cheese 16 different free amino acids have identified and roughly quantified by dimensional paper chromatography; the mean content of total free amino acids is about 10 mg.g-r cheese and the values ...

Protein breakdown in natural (non processed) Mahon cheese is greater than in processed and grated cheese, because the latter are made from green cheese and the processing temperature inactivates the proteolytic systems of ...

During the ripening of three diffe"rent series of Manchego cheese the evolution of free amino. acids was followed by a semiquantitative method. A total of 13-14 free amino acids were identified. Total free amino acids ...

The extent of cheese ripening and the type of proteolysis have been studied on 12 samples of commercial bola cheese by combining quantitative PAGE electrophoresis and the spectrophotometric measurement of soluble tyrosine ...

A collection of 58 proteolytic strains from 21 samples of commercial manchego type cheese has been constituted by screening techique on SMCA medium. The cell suspensions in caseinate solution, of the different isolated ...

Twelve Spanish cheese varieties have been screened for their aw and pH values. The sample of the internal mol-ripened cheese Cabrales, highly proteolyzed, has the lowest au, value (0.86). The samples of the fresh cheeses ...
