THE BASIC STEPS OF CHEESEMAKING Acid- and Acid/ Heat-Coagulated Cheeses The making of acid-coagulated and acid/ heat-coagulated fresh cheeses is quite simple, at least in comparison with that of most rennet-coagulated varieties. 6 or a combination of partial acidification and heating. After coagulation is complete, THE BASICS OF CHEESEMAKING █ 25 the cheesemaker has only one primary objective, which is to drain enough whey from the curd to attain the desired consistency in the fresh cheese. Salt is sometimes added to acidcoagulated and acid/heat-coagulated fresh cheeses—to the former usually at levels 1% or less, while the latter may be heavily salted, as in the case of queso blanco.

Similarly, there are various conditions, such as the length of time and temperature at each step, that can speed up or slow down the fermentation of lactose to lactic acid by LAB, thereby modulating the mineral content and pH of the cheese at the start of ripening. Over the centuries, cheesemakers in different times and places discovered various modifications that produced cheeses that were better suited for their needs. Often such modifications were beneficial because they had a desirable effect on moisture expulsion, the rate of lactic acid production, the incorporation of salt, or all three simultaneously.

Low-pH surfaces, in combination with cool temperatures (11 to 13°C) and high relative humidity (90%), favor the sequential growth of yeasts followed by molds, which opens the door to the production of bloomy-rind cheeses such as Brie and Camembert. 7). , ca. 50% or higher). The THE BASICS OF CHEESEMAKING █ 33 resulting high-moisture, low-pH cheese surface serves as a hospitable platform for the growth of the white mold Penicillium camemberti, which in former times was present as an adventitious environmental contaminant but in modern practice is either added to the cheese milk before renneting or sprayed onto the surface before ripening as a spore suspension (Fig.
