Acid is used in the process of making cheese to raise the acidity level of milk, which is an important step in cheese-making. This can be achieved by adding acids such as vinegar or lemon juice, or by using food-grade acids like lactic, citric, or acetic acid. Acidification can also be achieved through the addition of bacteria, which convert milk sugars into lactic acid. The type of acid used and the pH level play a role in determining the sweetness of the cheese's flavour. Acid-set or sour milk cheese is technologically simple to produce and accounts for around 25% of cheese production.

Blue cheese is made using phosphoric, hydrochloric, lactic, and citric acids
Acid is indeed used in the process of making cheese. Specifically, blue cheese is made using phosphoric, hydrochloric, lactic, and citric acids.
Blue cheese is made through the direct acidification of milk, using the aforementioned acids, prior to rennet coagulation. This process is essential for the rapid flavour development of blue cheese.
Lactic acid bacteria are used in the initial fermentation of the cheese. However, they are killed by the low pH, and the secondary fermenters, Penicillium roqueforti, take over. This mould breaks down the lactic acid, maintaining a pH in the aged cheese above 6.0.
The addition of modified milk fat stimulates a progressive release of free fatty acids via lipase action. During ripening, free fatty acids increase in amount, contributing to the characteristic flavour of blue cheese due to fat breakdown by Penicillium roqueforti.
The greenish-blue mouldy aspect of blue cheese is caused by Penicillium roqueforti, which produces several mycotoxins. However, health hazards due to these metabolites are considerably reduced due to the instability of certain toxins and the lack of optimal conditions for their production.

Lactic acid bacteria is used to curdle acid-set or sour milk cheese
Acid is indeed used in the making of cheese. Acid-set or sour milk cheese is a type of cheese that is curdled or coagulated by natural souring, often from lactic acid bacteria, or by the addition of acid. This type of cheese is simple to produce. When making soft acid-set cheese using bacteria, the coagulum results from the production of lactic acid by the starter microorganisms.
Lactic acid bacteria (LAB) play an essential role in traditional cheese-making, either as starter cultures that cause the rapid acidification of milk or as secondary microbiota that play an important role during cheese ripening. The enzymes produced by such dynamic LAB communities in raw milk are crucial, as they support proteolysis and lipolysis as chief drivers of flavour and texture of cheese. The metabolites produced during fermentation, with the exception of volatiles, remain in the food, inhibiting the growth of undesirable bacteria.
The quality of milk is important for LAB growth, as toxic residues and contaminants can affect its suitability for cheese-making and the safety of the final product. The most common chemical residues found in milk are antibiotics, which disturb starter cultures and NSLAB, preventing milk acidification and normal cheese ripening.
Acid-setting is a method of coagulation that accounts for around 25% of cheese production. These are generally fresh cheeses like queso blanco, quark, and cream cheese. The other 75%, which includes almost all ripened cheeses, are rennet cheeses.
Citric acid is also used to make a variety of cheeses, including 30-minute Mozzarella, Ricotta, and Paneer. Adding citric acid to milk raises the acidity level, which is an important step in cheese-making.

Citric acid is added to milk to make 30-minute Mozzarella, Ricotta, and Paneer
Acid-set or sour milk cheese is made by curdling milk, often with the addition of acid. This process is used in around 25% of cheese production and is technologically simple to carry out.
Citric acid is used to make a variety of cheeses, including 30-minute Mozzarella, Ricotta, and Paneer. Adding citric acid to milk raises the acidity level, which is an important step in the cheese-making process. The acid is dissolved in a small amount of cool, non-chlorinated water and then added to the milk when specified in the recipe.
Citric acid is a key ingredient in acid cheeses, and the amount used should be diluted as directed by the recipe. The acid is derived from non-GMO cane or beet sugar and does not contain Glutamate, Glutamic acid, or hydrolyzed protein.
To make 30-minute Mozzarella, the milk should be warmed to a temperature of 86-88°F (30-31°C) until curds are formed. The curds are then cut into approximately 1" cubes. The mixture is then placed in cool (50°F) water for 5 minutes, followed by ice water for 15 minutes. The Mozzarella can be stored in the refrigerator for up to a week or placed in oil and herbs and then stored.

Adding acid to milk raises its acidity level, an important step in cheese-making
Acid is indeed used in the making of certain types of cheese. The process of making cheese involves curdling or coagulating milk, and one way to do this is by adding acid. This method is called acid-setting or acid-coagulation. Adding acid to milk raises its acidity level, which is an important step in making certain types of cheese.
Acid-set or sour milk cheese is technologically simple to produce. It is curdled (coagulated) by natural souring, often from lactic acid bacteria, or by the addition of an acid. This process accounts for around 25% of cheese production. These are generally fresh cheeses like queso blanco, quark, and cream cheese.
The acidification of milk can be accomplished directly by adding an acid such as vinegar or lemon juice. This is done in a few cases, for example, when making paneer or queso fresco. However, it is more common to use starter bacteria that convert milk sugars into lactic acid. The same bacteria (and the enzymes they produce) also play a large role in the eventual flavor of aged cheeses. Most cheeses are made with starter bacteria from the Lactococcus, Lactobacillus, or Streptococcus genera.
The type of acid used in the direct acidification process can vary. Blue cheese, for example, can be made by adding phosphoric, hydrochloric, lactic, or citric acids prior to rennet coagulation. Citric acid is used to make a variety of cheeses, including 30-minute mozzarella, ricotta, and paneer. To use citric acid, it must first be dissolved in cool, non-chlorinated water and then added to milk according to the recipe.

Acids are used to adjust the pH level of milk, affecting the sweetness of the cheese
Acids are used in the process of making cheese to adjust the pH level of milk, which in turn affects the sweetness of the cheese. This process is known as direct acidification, and the acids used include phosphoric, hydrochloric, lactic, and citric acids. These acids are added to milk before rennet coagulation.
Acid-set or sour milk cheese is produced by curdling milk through natural souring, often from lactic acid bacteria, or by adding acids. This method of coagulation accounts for around 25% of cheese production and includes fresh cheeses like queso blanco, quark, and cream cheese.
Citric acid, in particular, is commonly used in cheesemaking. Adding citric acid to milk raises its acidity level, which is crucial in the cheesemaking process. Citric acid is used to make a variety of cheeses, including 30-minute Mozzarella, Ricotta, and Paneer. To use citric acid, it must first be dissolved in cool, non-chlorinated water before being added to milk as per the recipe specifications.
The type of acid used by cheesemakers is important as it determines the pH level required for the desired sweetness of the cheese's flavor. Maintaining the correct pH levels is crucial, and some mass-produced cheeses use food-grade caustic soda to neutralize the acid before heating the mixture and adding the coagulating acid.
