Macaroni and cheese is a beloved comfort food for many, but the ingredients in boxed macaroni and cheese are often very different from those used in homemade versions. One of the key ingredients in boxed macaroni and cheese is lactic acid, which is added to the cheese sauce mix to enhance the sourness of the cheese and improve the overall flavour. Lactic acid is a product of lactose, a type of sugar found in milk, being converted by bacteria during the fermentation process. The addition of lactic acid is especially important in products like Kraft's macaroni and cheese, which use non-fermented ingredients like milk protein concentrate, resulting in a lack of acidity.

Lactic acid is added to macaroni and cheese to provide a sour taste
Lactic acid is produced by bacteria that ferment lactose, a sugar found in milk. In cheese-making, bacteria convert lactose into lactic acid, which not only adds flavour but also affects the texture and functionality of the final product. This process is essential in creating the desired taste profile for macaroni and cheese.
The sourness of the cheese in macaroni and cheese is often attributed to the presence of lactic acid. While real cheese obtains its sourness from the conversion of lactose to lactic acid by bacteria, processed cheese products like macaroni and cheese may require additional lactic acid to achieve the desired level of acidity. This is because non-fermented ingredients, such as milk protein concentrate, can reduce the overall acidity of the cheese sauce.
The addition of lactic acid to macaroni and cheese is part of the broader trend of using cleaner ingredients in packaged food products. Consumers are increasingly seeking convenient, affordable, and familiar foods that make them feel less guilty about their dietary choices. By removing artificial colours and flavours and focusing on more natural ingredients, companies like Kraft are responding to this demand for "cleaner" options.
In summary, lactic acid is added to macaroni and cheese to provide a sour taste and enhance the overall flavour profile. This ingredient plays a crucial role in the chemistry of macaroni and cheese, contributing to the complex interplay of flavours and textures that make this dish a favourite for many.

It is added to make up for the lack of acidity in non-fermented ingredients
Macaroni and cheese is a simple dish with a complex chemistry. The cheese in macaroni and cheese is made by souring milk with lactic acid bacteria, which convert lactose in the milk to lactic acid. This process adds a sour taste to the cheese. However, when making macaroni and cheese, non-fermented ingredients such as milk protein concentrate are added to the cheese sauce, reducing its acidity. To compensate for this loss of acidity, additional acids such as citric acid and lactic acid are added to the macaroni and cheese. These added acids restore the sour notes that are characteristic of cheese.
Lactic acid plays a crucial role in the flavour, texture, and functionality of the final cheese product. By converting lactose into lactic acid, cheesemakers can manipulate the characteristics of the cheese to create their desired profile. This process is a type of fermentation reaction, where lactose is broken down into by-products such as acid and gas.
In the context of macaroni and cheese, the cheese sauce mix often contains non-fermented ingredients like milk protein concentrate. These ingredients dilute the acidity of the cheese, necessitating the addition of lactic acid to restore the desired level of sourness.
It's worth noting that some consumers are increasingly conscious of the ingredients in their packaged food products, favouring "cleaner" options. This trend has led to changes in the ingredients used in popular macaroni and cheese products, such as removing artificial colours and flavours. However, altering ingredients can be challenging for manufacturers, as any changes that affect sensory properties like taste or texture may provoke negative reactions from loyal customers.
The process of making macaroni and cheese involves a delicate balance of ingredients and chemical processes. The addition of lactic acid to compensate for the lack of acidity in non-fermented ingredients is just one example of the complex chemistry behind this beloved comfort food.

Lactic acid is a by-product of lactose being converted by bacteria
Lactic acid is added to macaroni and cheese to enhance its flavour and texture. It is a by-product of lactose being converted by bacteria.
Lactic acid is a carboxylic acid that is produced by the fermentation of sugars, including lactose. Lactose is a type of sugar composed of two simpler sugars, glucose and galactose, linked by a specific type of bond. This bond must be broken for our bodies to absorb lactose. The enzyme lactase, produced in the intestines, is responsible for breaking this bond. However, in individuals with lactose intolerance, the body does not produce sufficient lactase, leading to the fermentation of lactose by gut microbes.
In the context of cheese production, lactic acid bacteria play a crucial role in converting lactose into lactic acid. This process, known as fermentation, not only produces lactic acid but also contributes to the development of other compounds, adding complexity to the flavour and texture of the cheese. The conversion of lactose into lactic acid by bacteria is a fundamental step in cheesemaking, and understanding its nuances can significantly impact the final product.
Cheese is an essential component of macaroni and cheese, and the lactic acid present in the cheese contributes to the overall flavour and texture of the dish. The addition of lactic acid to macaroni and cheese products, such as Kraft Macaroni & Cheese, enhances the acidity and sourness of the cheese sauce. This is especially important when using non-fermented ingredients like milk protein concentrate, which can result in a less acidic sauce. By adding lactic acid, manufacturers can replicate the acidity typically found in real cheese, where lactic acid bacteria have converted lactose into lactic acid during the cheese-making process.
In summary, lactic acid is a by-product of lactose conversion by bacteria, and its presence in macaroni and cheese contributes to the desired flavour and texture characteristics. The addition of lactic acid is just one aspect of the complex chemistry behind this beloved comfort food.
