The diagram shows the multi-stage process of producing yogurt.
Overall, it is clear that yogurt is made through four-stage process in which a mixture of substances is exposed to various temperatures. This transforms the mixture into yogurt, which is then packaged.
Looking more closely at the diagram, one can see that the process begins when the ingredients, which consists of stabilizers, dry milk, sugar, and milk are mixed together in hygienic stainless steel vessel. At this point, this mixture is heated to 85 degrees Celsius, starting the pasteurization process. Then, it is cooled to 42 degrees Celsius. This the homogenization phase. After this phase is completed, cultures are added to the blend to begin the fermentation. The mixture is then stirred before the temperature is reduced to 7 degrees Celsius, and the fermentation process ends. In the final step, the finished yogurt product is packaged into individual containers to be sold.
