Cheese is a beloved and versatile food, with a wide range of varieties to suit every palate. Cheddar is a hard and acidic cheese, with a pH level below 4.5, which is created by bacteria producing lactic acid. This low pH level is crucial in preventing the growth of harmful bacteria such as Salmonella, Listeria, and E. coli, making the cheese safe to eat and preserving its unique flavour profile. However, is cheddar cheese high in alkaline?

What You'll Learn
Cheddar is a hard, acidic cheese with a low pH level
The pH level of cheese can significantly impact its flavour, texture, and safety. A lower pH corresponds to higher acidity, and vice versa. Cheese with a pH below 4.5 is considered safe from pathogen growth, while cheese with a higher pH, closer to 5.5, can foster the growth of pathogens such as Salmonella, Listeria, and E. coli.
Cheddar cheese falls into the category of hard, acidic cheeses with low pH levels. This is due to the production of lactic acid by bacteria, which further lowers the pH and creates an environment hostile to other bacteria. The low pH of cheddar contributes to its characteristic sharpness and hardness.
While cheese is naturally acidic, some suggest that an alkaline cheese-based meal can be achieved by pairing cheese with alkaline foods such as vegetables and fruits. This approach focuses on creating alkaline meals that include cheese rather than seeking inherently alkaline cheeses, as cheese is a protein food and thus acid-forming.

Measuring pH is essential when making cheese
The pH level of cheese is a measure of its acidity or alkalinity. It is measured on a 14-point scale, with 7 being neutral. The pH level of cheese can vary widely, with most cheeses having a pH range of 4.5 to 7. For example, blue cheese has a very low pH of around 4.6, while the pH of milk typically starts around 6.7.
The pH level of cheese can be tested using a pH meter or litmus paper. A pH meter is a more accurate and reliable method, which is why it is always used in commercial cheese-making processes. It uses a pH-sensitive electrode and a reference electrode to measure the electrical potential difference. The pH meter is calibrated using buffer solutions of known pH values and the cheese sample is placed in a container with distilled water to create a slurry before taking a reading. Litmus paper, on the other hand, changes colour depending on the pH of the substance being tested. It is a more common method for small DIY cheese-making processes.
Measuring pH during cheese-making is critical for quality control and food safety. It helps indicate contamination from bacteria or chemicals and provides a method to estimate the acid development of a dairy product. The pH level also determines how moist the cheese is, with a higher pH resulting in a drier, more brittle texture. Additionally, the pH level needs to be within a certain range for the rennet to coagulate properly and for the curds to form correctly.

pH levels determine when to cut the curd
Cheddar cheese is not specifically mentioned in relation to alkalinity in the search results. However, the pH level of cheese is an important factor in its production, and pH is directly related to alkalinity. A pH level of 7 is considered neutral, with levels below 7 being acidic and levels above 7 being alkaline.
The pH level of cheese affects its flavour, texture, and safety. A higher pH level will result in a milder flavour and softer texture, while a lower pH level will produce a sharper flavour and firmer texture. Measuring the pH of the cheese curds is essential for determining when to cut the curd, as this is a critical step in the cheese-making process.
The pH level of cheese can be measured using a pH meter, and it plays a crucial role in the ripening process. The pH level can also help determine how moist the cheese will be. A higher pH level may cause the cheese to lose moisture, resulting in a brittle and crumbly texture.
During cheese production, the pH level of the milk and the amount of acid added are important factors that influence the final pH of the cheese. The pH level can change during the ripening process due to buffering or external influences. Additionally, the pH level can be affected by the fermentation of the starter culture, with a lower initial pH resulting in a lower pH during fermentation.
In summary, pH levels are crucial in cheese-making, and measuring them is essential for determining the optimal time to cut the curd. The pH level impacts the flavour, texture, and safety of the final product, and it plays a significant role in the ripening process. By controlling the pH level, cheese makers can produce high-quality, safe, and delicious cheese.

pH levels affect the flavour, texture and safety of cheese
The pH level of cheese affects its flavour, texture, and safety in several ways. Firstly, pH influences acidity, which in turn impacts flavour. A higher pH level results in lower acidity, allowing the flavours of the milk to come through, creating a milder and slightly sweeter taste. Conversely, a lower pH level indicates higher acidity, which can make the cheese tangier and saltier. For example, Stilton has a lower pH than Gorgonzola, resulting in a firmer and crumblier texture and a tangier, saltier flavour.
Secondly, pH affects the texture of cheese. A higher pH level can lead to increased moisture content, resulting in a weak and pasty texture. On the other hand, lower pH levels can decrease moisture content, leading to a harder and firmer texture. The moisture content also influences microbial growth, with higher moisture levels promoting more microbial growth, which can impact food safety.
Additionally, pH plays a crucial role in food safety. As pH decreases, acidity increases, creating an environment that inhibits the growth of harmful pathogens and bacteria. This safety measure is particularly important in cheese production to prevent the growth of undesirable microorganisms.
Lastly, pH influences the melting properties of cheese. A lower pH, indicating higher acidity, can affect how well a cheese melts and stretches. For example, blue cheese has a very low initial pH, but as it ages, the blue mould metabolises and raises the pH, reducing its acidity. This change in pH and acidity affects the cheese's melting properties and overall characteristics.
Overall, monitoring and controlling pH levels are vital in cheesemaking to ensure the desired flavour, texture, and safety characteristics of the final product.

Cheese is an acid-forming food, but it can be balanced with alkaline meals
Cheese is an acid-forming food with a pH level that can vary from 4.5 to 6.5. The pH level of cheese is influenced by factors such as the type of bacteria present, the amount of acid created, and the starting pH of the milk. For example, blue cheese starts with a low pH of around 4.6 but then increases to 6.5 due to the metabolism of the blue mold. The pH level of cheese is crucial in the cheese-making process as it determines the appropriate time for cutting the curd and influences the growth of bacteria, flavour, texture, and safety of the final product.
Cheddar cheese, in particular, is known for being a hard and acidic cheese with a pH level typically below 6.5. This low pH environment inhibits the growth of harmful pathogens such as Salmonella, Listeria, and E. coli, making cheddar relatively safe from pathogen contamination.
While cheese is generally considered an acid-forming food, it can be balanced with alkaline meals to create a more neutralising effect in the body. This can be achieved by incorporating vegetables, fruits, and other alkalizing foods into recipes that include cheese. By pairing cheese with alkaline ingredients, the overall acidity of the meal is reduced.
Additionally, when considering the acid-forming nature of cheese, it is important to acknowledge the role of protein. Cheese is a good source of protein, which is an essential nutrient for the body. However, protein-rich foods, including cheese, tend to be acid-forming. Therefore, it is recommended to focus on creating balanced meals by pairing cheese with alkaline foods rather than seeking out alkaline cheese alternatives, which may not offer the same nutritional benefits.
