Salt is an essential ingredient in cheese production, influencing various aspects of cheese, including shelf life, flavour, texture, enzyme activity, microbial proliferation, and more. The primary reason for salting cheese is to slow down or stop the bacterial process of converting lactose to lactic acid, which is essential for proper ripening. Salt also draws out moisture from the cheese, aiding in the development of a good rind and inhibiting the growth of mould. Additionally, salt acts as a natural preservative, enhancing and intensifying flavours while simultaneously suppressing unfavourable ones. The salt used in cheesemaking is typically non-iodized salt, with cheese makers employing several methods to incorporate salt, including direct salting, brine solutions, and dry salting.

Salt preserves cheese and slows down the process of bacteria converting lactose to lactic acid
Salt is an essential ingredient in cheese production, influencing various aspects of cheese, including its shelf life, flavour, and texture. It is a natural preservative, helping to prepare cheese for ageing. Salt also slows down the process of bacteria converting lactose to lactic acid. This is the primary reason for salting cheese. During the brining process, most of the lactose is removed. If the cheese is not salted, the residual moisture within the cheese contains enough lactose to produce more acid than is ideal for proper ripening.
Salt is added to cheese through several different methods, including direct salting, where salt is sprinkled over cut-up curds, and brining, where whole wheels or blocks of cheese are submerged in a salty brine solution. The brining method allows for the gradual penetration of salt and aids in rind formation, as the outer layer of the cheese dehydrates. The brine solution is typically made with non-iodized salt, as iodine inhibits the cultures and bacteria necessary for cheese.
The salt molecules spread out and enter the cheese body, drawing whey (moisture) out of the cheese and causing it to dry. This process affects the cheese's texture and stability and alters its protein structure. Salt also enhances the cheese's flavour and can cover up unpleasant ones. It is essential in the development of a good rind and helps kill bacteria and other harmful growth.
While salt is crucial in cheese-making, excessive salt consumption has been linked to adverse health effects. As a result, there have been efforts to reduce salt usage in food products, including cheese. The cheese industry has explored options such as limiting salt quantities or replacing sodium chloride with potassium chloride to decrease sodium content.

Salt enhances the flavour of cheese and can cover up unpleasant tastes
Salt is an essential ingredient in cheese production, influencing various aspects of cheese, including its flavour. Salt enhances the flavour of cheese and can also help cover up unpleasant tastes. This is achieved through the diffusion process, where salt molecules enter the cheese body and spread out equally, permeating throughout its structure.
Salt is added to cheese through different methods, including direct salting, where salt is sprinkled onto cut-up curds, and brining, where cheese is submerged in a salty brine solution. The choice of method depends on various factors and the expertise of the cheese maker.
The salt content in the brine solution is important, with an 18% brine solution commonly used for cheese making. This provides adequate salt absorption during the brining process, allowing the cheese to absorb the right amount of salt while removing excess moisture.
The use of non-iodized salt is crucial in cheese making, as iodine can inhibit the growth of desired cultures and bacteria. Fine sea salt or flakey kosher salt are good options, as they are unbleached and add fewer chemicals to the cheese.
While salt is essential for flavour enhancement and development, it also serves other purposes in cheese making. Salt acts as a natural preservative, helping to extend the shelf life of cheese and prepare it for aging. It controls moisture content, causing the curds to shrink, and is essential for developing a good rind. Additionally, salt helps to inhibit the growth of unwanted bacteria and mould, contributing to the overall quality and safety of the cheese.

Salt dries out the cheese, altering its texture and stability
Salt is an essential ingredient in cheese production, influencing various aspects of the cheese-making process and the final product. One of its key roles is to draw out moisture from the cheese, altering its texture and stability.
When salt is applied to cheese, it absorbs moisture from the cheese's body, causing it to dry out. This process, known as diffusion, involves salt molecules entering the cheese and spreading throughout its structure. The presence of salt causes moisture removal, directly impacting the cheese's texture by altering its protein structure.
The removal of moisture through salting has a significant impact on the cheese's stability. By reducing the moisture content, the cheese becomes less susceptible to microbial growth and the development of moulds, which can affect its stability and shelf life.
Additionally, the salt concentration can influence the behaviour of microbes and enzymes in the cheese, further impacting its texture. A critical factor to consider is the type of salt used. Non-iodized salt is preferred in cheese-making, as iodine can inhibit the growth of desired cultures and bacteria.
Cheese makers employ various methods to incorporate salt into their cheese, including direct salting, where salt is sprinkled onto cut-up curds, and brine-salting, where cheese is submerged in a salty brine solution. The choice of method depends on several factors, and the cheese maker's expertise is crucial in determining the best approach for their specific cheese variety.

Salt helps develop a good rind by dehydrating the outer-most layer of the cheese
Salt is essential in the development of a good rind on cheese. This is because salt dehydrates the outer-most layer of the cheese, creating a dehydrated protein layer that acts as an early-stage rind. This process also aids in the inhibition of mould growth, which is attracted to cheese.
Salt dehydrates the cheese by drawing out the whey (moisture) from the cheese. This process is called diffusion, where salt molecules enter the cheese body and permeate throughout its structure, while water is simultaneously leaving the cheese. This loss of moisture dries out the cheese and has a pronounced effect on its texture and stability.
The presence of salt also affects the behaviour of microbes and enzymes, which can have a drastic effect on the texture and flavour of the cheese. Salt can act as a natural preservative and helps prepare cheese for ageing. It is important to use a non-iodized salt when making cheese, as iodine inhibits the cultures and bacteria that are wanted in the cheese.
The salting process can be done in a few different ways. One method is to submerge the whole wheel or block of cheese in a salty brine solution, which allows for the gradual penetration of salt. Another method is to sprinkle cut-up curds with salt, known as direct or dry salting.
