This Master thesis called Comparison of methods for measuring milk coagulation deals with a major technological step in the production of cheese, which is the process of curdling of milk. Two methods for measuring this process were compared, particularly the visual and instrumental method utilizing nephelo-turbidimeter. Based on statistical data processing in three cases, a difference was observered between the average visual measurement and instrumental measurement of significant 99%. Furthermore, the impacts on curdling of milk were assessed what showed that the best default property for the process of curdling had a pasteurized milk sample with the addition of CaCl2. On the basis of calculations in this thesis it has been concluded that to curdle a 100 l of milk with rennet CHY-MAX a 0,2 liters of the rennet is required. The same amount of milk is curdled with 1 litre of rennet Lactochym. In assessing the economics of using rennet Lactochym and CHY-MAX it has been found that for cost optimization it is more appropriate to use rennet CHY-MAX with a strentgh of at least 190 IMCU/ml diluted in distilled water at a ratio of 1:5.
