Pasta filata cheeses obtain their characteristic structure and properties during the heating-stretching process. It is a transformation of the curd into a plastic and stretchable paste. This change is achieved by an appropriate combination of pH and calcium content in the curd during the heating-stretching step. These two key parameters are controlled by the activity of the starter cultures, or by a direct acidification of milk with organic acids during the production of the curd. During the heating-stretching process the amorphous protein structure of the curd is transformed into an oriented structure composed of parallel protein fibres. The resulting plastic paste is easily molded into various forms and shapes.
