Then, apply hydraulic pressure to the coagulum. Salting also adds characteristic flavour and texture to the cheese.Īfter brining, keep the curd fractions in the cheese hoops.It also reduces the amount of moisture in the finished cheese.It suppresses the growth of spoilage microorganisms.Brining is a step necessary for cheese making: You could either sprinkle salt over the loose curd or dip the freshly made cheese in the brine solution. It is a process where salt acts as a stabilizer, which increases the shelf life of the cheese. The knitting of curd is a step that contributes to the texture by modifying the curd particles and produce a compact mass of cheese. The curd is obtained after the removal of whey, which appears as a knitted mat. It also controls the amount of moisture content.Īfter cooking the whey-curd mixture, drain out the whey from the vat.To suppress the growth of spoilage microorganisms.For the control of acid production by the starter culture.This step is necessary for the following: The cooking involves stirring the whey-curd mixture to obtain a compact mass of coagulum. The time and temperature of cooking cheese usually differ in different processes of cheesemaking. Then, the fractions of coagulum are heated upto 38 degrees Celsius for the desired time. The coagulum fractioned into small cubes will produce low moisture cheese, while the large cubes will produce high moisture cheese. This step allows easy separation of whey out of the curd. Then, fraction the coagulum (curd) into small cubes with a cheese cutter. This step allows the coagulum to ferment till it reaches a pH (6.4). The alternative sources for the rennet enzyme are the blends of rennin and pepsin, fungi-based coagulants etc.įungi-based coagulants are widely used in the United States, including fungal strains like Mucor pusillus, Endothia parasitica etc. It coagulates the colloid casein to insoluble paracasein and carbohydrate-rich peptide fraction.Īlso, left the milk undisturbed for about 30 minutes to obtain a firm coagulum. Rennet aids in milk curdling or coagulation, as it functions as a coagulant. Thus, the proper growth of starter culture lowers the pH of the media (by forming acid) and adds more flavour to the cheese. PRODUCTION PROCESSES DEFINITION FREEMilk must be free from any antibiotics for the bacteria to carry out the fermentation.Īntibiotics may cause retardation in the growth of the starter culture and the production of acid, which in turn produce inferior quality cheese. The ripening step promotes bacterial growth to start the fermentation process. Nowadays, concentrated frozen starter cultures are also available in the market, which can be directly added to the milk. One can use the strains of Streptococcus bacteria ( S. Different cheese requires different starter culture to produce cheddar cheese. Then, add the starter culture into the milk and subject it to heat (90 degrees Fahrenheit) for 30 minutes to ripen. After pasteurization or heating, cool the milk to the temperature necessary for the growth of the starter culture. Cheese produced from raw milk requires ageing for a maximum of 60 days. It reduces the spoilage of organisms and improves the environment for the growth of starter cultures. This step generally optimizes the protein and fat ratio of the milk to produce superior quality cheese. Subject milk to the centrifugation to clarify the small exogenous particles or somatic cells during the standardization process. The milk should be free of any off flavours, microbial contamination, antibiotics and chemical contaminants. Milk serves as a raw material source for cheese production, which can be obtained through milk-producing animals like a cow, buffalo, goat etc. Like every industrial production, the process of cheese making also requires a sterile environment to avoid any microbial contamination. The production of cheese includes the following sequential steps: The production of cheese is a lengthy procedure to carry out, which involves high maintenance and cleanliness of the equipment, and requires a long time. The production of acid after the fermentation by the starter culture and the salting step mainly add longevity to cheese.Ĭheese is the milk product that forms by the coagulation of milk protein (Casein). The formation of cheese requires milk as a raw material. Content: Cheese ProductionĬheesemaking refers to the production of cheese by using bacterial culture, enzymes and stabilizers to condense the milk proteins and fat and to preserve the cheese. In this post, we will discuss the definition and all the steps in the production process of cheese. Cheese is a milk concentrate (contains casein and fat).
