Feta cheese is a popular variety of cheese that originated in Greece and is now enjoyed worldwide. It is a soft, white, and brined cheese with a tangy and sharp flavour when made with sheep's milk and a milder taste when made with goat's milk. While feta is known for its relatively low lactose content, making it suitable for some individuals with lactose intolerance, it is important to note that it contains casein, a type of protein found in milk products. Casein can trigger allergic reactions in some people, so those with dairy allergies should avoid consuming feta cheese.

What You'll Learn
Feta cheese is not casein-free
Feta cheese is a popular variety of cheese that originated in Greece and is now enjoyed worldwide. It is a soft, white, and brined cheese with a tangy and sharp flavour when made with sheep's milk and a milder flavour when made with goat's milk. The production of feta cheese is a labour-intensive process that involves heating milk to a specific temperature, mixing it with rennet (a natural enzyme that coagulates the milk), and then cutting the curds into small pieces to release the whey. The curds are then transferred to moulds and pressed to remove excess liquid before being immersed in a brine solution for preservation and enhanced flavour.
While feta cheese is a good source of calcium, phosphorus, and protein, it also contains casein, a protein that can be a possible tumour promoter. Casein is responsible for the white colour and creamy texture of feta cheese, but it can be a concern for those with dairy allergies or lactose intolerance. Those with lactose intolerance may experience digestive problems such as diarrhoea, bloating, and gas when consuming dairy products containing casein.
It is worth noting that feta cheese made with unpasteurized milk may be contaminated with Listeria bacteria and is not recommended for pregnant women. For those with dairy allergies or lactose intolerance, there are casein-free cheese alternatives made from nuts, soy, or other non-dairy ingredients. These alternatives can provide a healthier option for individuals who want to enjoy cheese without the presence of casein.

Casein is a protein found in milk
Feta cheese is made from sheep and goat's milk. It is a soft, white, and brined cheese that originated in Greece. Feta cheese contains casein, a protein commonly found in milk mammalian milk. Casein is responsible for the white colour and creamy texture of dairy products. It is the primary emulsifier in milk, helping to mix oils, fats, and water. Casein is a family of related phosphoproteins, including αs1, αs2, β, and κ-casein, which have open and flexible conformations. These proteins are composed of hydrophilic and hydrophobic segments, resulting in an amphiphilic character with micelle-forming properties. Casein is also a source of essential amino acids, calcium, and phosphorus, making it a recognised source of nutrients.
Casein is the chief protein in milk, accounting for about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and cow milk have higher casein content than other types of milk, while human milk has a particularly low casein content. Casein is usually made from skim milk, and there are three methods for its production: natural souring, acid precipitation, and rennet extraction. In all three methods, the whey is drawn off, and the curd is washed, drained, pressed, dried, ground, and packed for sale.
Casein has a wide range of applications beyond its presence in milk. It is used as a food additive and in prepared foods, medicines, dietary supplements, and cosmetics. Additionally, it has industrial applications such as leather seasoning and dressing, shoe cleaning and polishing, textile printing and sizing, insecticide sprays, and soap-making. Casein is also used in the creation of adhesives, paints, and glues.
While casein has many uses and provides nutrients, some individuals may experience an allergic reaction or intolerance to it. Casein intolerance, also known as "milk protein intolerance", occurs when the body cannot break down the proteins in casein. The prevalence of casein allergy or intolerance ranges from 0.25% to 4.9% in young children, and a significant portion of those on the autism spectrum may also be affected. Therefore, those with dairy allergies should avoid consuming feta cheese due to its casein content.

Feta is made from goat and sheep's milk
Feta cheese is a Greek staple, traditionally made from sheep and goat's milk. It is a soft, white, and brined cheese with a tangy and salty flavour. The Protected Designation of Origin (PDO) product status means only cheese made in specific Greek regions can be labelled as "feta".
Feta is produced in blocks and has a firm texture, but it can also crumble when cut. The flavour of feta varies depending on the milk used. Sheep's milk lends a tangy and sharp taste, while goat's milk results in a milder flavour.
The process of making feta is labour-intensive and requires skill. Farmers carefully select high-quality milk, ensuring it is free from impurities. This attention to detail contributes to the cheese's unique flavour and texture. Once the milk is collected, it is heated and mixed with rennet, a natural enzyme that coagulates the milk. The mixture is left undisturbed, allowing curds to form, which are then cut into pieces and stirred to release the whey. The curds are then transferred to moulds and pressed to remove excess liquid. Finally, the cheese is immersed in a brine solution for preservation and enhanced flavour.
Feta cheese contains casein, a protein found in milk that gives it its creamy texture and white colour. While feta is made primarily from sheep and goat's milk, it does contain dairy. This is important to note for individuals with dairy allergies, as casein can trigger allergic reactions.

Casein allergies can be dangerous
Feta cheese, a popular variety of cheese with a rich history that dates back thousands of years, is made from sheep's or goat's milk. It is a staple in Greek cuisine and is often used in Mediterranean dishes. However, despite its widespread consumption, it is important to be aware of potential allergies associated with this dairy product. Casein, a protein found in milk, can trigger allergic reactions in some individuals. Casein allergies occur when the body's immune system mistakenly identifies casein as harmful, leading to the production of allergic antibodies. This can result in mild discomfort or life-threatening anaphylaxis, which requires immediate medical attention.
The best way to prevent an allergic reaction to casein is to follow a strict casein-free diet, as even minuscule amounts can trigger a response. This involves avoiding not only dairy products but also foods that may have been exposed to dairy, such as deli meats cut with equipment used for cheese. Reading food labels carefully is crucial, as casein may be present in nondairy creamers, flavorings, crackers, and cookies. Additionally, when dining out, it is important to inform servers about your casein allergy before ordering.
While feta cheese is a popular and flavorful ingredient, it is essential to be cautious about its consumption if you have a dairy allergy. Casein allergies can be life-threatening, and the only way to prevent allergic reactions is to avoid casein-containing foods entirely. Consulting with healthcare professionals and carefully reviewing food labels are essential steps to ensure the safety of individuals with casein allergies.

Casein-free cheese alternatives exist
Feta cheese is not casein-free. Casein is a protein found in milk, and feta is predominantly made from sheep's or goat's milk. This protein gives milk its creamy texture and white colour. For some, casein can trigger allergic reactions, so it is important to know that feta contains casein and should be avoided to prevent an allergic reaction.
However, casein-free cheese alternatives do exist. Many people are confused about this, as some cheese alternatives are not actually vegan and dairy-free. For example, some brands sell both vegan and non-vegan cheese alternatives, with similar packaging, making it easy to accidentally purchase the wrong one. However, a product labelled as vegan is an indication that it contains no animal products, including dairy and its derivatives, and therefore no casein.
There are also lactose-free cheese alternatives that are not dairy-free, and therefore not casein-free. These products are suitable for those who are lactose intolerant but not for those with dairy allergies.
Casein-free cheese alternatives are often nut- or soy-based. Nut-based cheeses are becoming one of the best options on the market for those with casein or lactose allergies. Most types of this dairy-free cheese are made from cashews, which are high in fat, aiding in creating a creamy texture.
Some examples of casein-free cheese alternatives include Follow Your Heart, a non-dairy, non-soy, and casein-free cheese alternative, and Daiya, a dairy-free cheese that has become a staple in the veggie cheese arena.
