Blue cheese is a type of cheese characterised by its blue veins and strong flavour. It is made using cow's, goat's, or sheep's milk and Penicillium roqueforti, a type of mould. Blue cheese is known for its sharp, salty taste and crumbly texture, and is often used in salads, sauces, and as a topping for pasta or eggs. While blue cheese contains some lactose, it is generally considered suitable for individuals with lactose intolerance due to its low lactose content. However, it is always recommended to listen to your body and consume blue cheese in moderation if you have lactose intolerance.

What You'll Learn
Blue cheese is low FODMAP
Blue cheese is a dairy product made from milk that has been cultured with Penicillium roqueforti inoculum and fermented. It is known for its distinctive blue veins and strong flavour. While blue cheese is typically low in lactose, some people may still experience digestive issues after consuming it. This could be due to an allergy to milk protein or sensitivity to casein, which is also found in dairy products.
Blue cheese is generally considered to be low FODMAP, which stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. FODMAPs are short-chain carbohydrates that can be poorly absorbed in the small intestine, leading to digestive issues for some people. A low FODMAP diet is often recommended for those with Irritable Bowel Syndrome (IBS) or other digestive disorders to help manage their symptoms.
The low lactose content of blue cheese makes it a suitable option for those following a low FODMAP diet, as lactose is a FODMAP. However, it's important to note that individual tolerance may vary, and some people may still experience digestive issues after consuming blue cheese. This could be due to the presence of other FODMAPs in the cheese or other individual factors.
To ensure blue cheese is low FODMAP, it is recommended to check the nutrition label and choose cheeses with 1 gram or less of lactose per serving. Additionally, the Monash University Low FODMAP App can be a helpful resource for checking the FODMAP content of specific cheeses. It's also important to remember that a low FODMAP diet is not a dairy-free diet, and there are other low FODMAP cheese options available as well.
Overall, blue cheese is typically considered a low FODMAP food due to its low lactose content. However, individual tolerance may vary, and it's always best to consult with a healthcare professional or dietitian for personalized dietary advice.

Blue cheese is made with Penicillium roqueforti
Blue cheese is a type of cheese characterised by blue veins and a distinctive flavour. It is made through a complex fermentation and maturation process, primarily mediated by lactic acid bacteria and fungi.
One of the key ingredients in blue cheese is Penicillium roqueforti, a saprophytic fungus commonly found in nature. It can be isolated from soil or decaying organic matter. Penicillium roqueforti is used as a fungal adjunct culture, or secondary starter culture, in the production of blue-veined cheeses. It is particularly well-adapted to the conditions during blue cheese manufacture, including low oxygen levels and temperatures.
The fungus contributes significantly to the characteristic blue colour and flavour profile of blue cheese. It accomplishes this through its involvement in lipolysis and proteolysis, producing volatile and non-volatile aroma compounds, with methylketones being the most abundant.
Penicillium roqueforti is added to autoclaved, homogenised milk along with salt, sugar, or both, to create a sterile solution. This mixture is then incubated for several days at a specific temperature range. The process is repeated with additional salt and/or sugar, followed by aerobic incubation. Alternatively, a fermentation medium is created by mixing sterilised, homogenised milk and non-fat solids or whey solids, to which a Penicillium roqueforti culture is added. Modified milk fat is then incorporated, facilitating the release of free fatty acids, which is essential for the rapid development of the distinct blue cheese flavour.

Blue cheese is safe for those with lactose intolerance
Blue cheese is a dairy product, and it does contain lactose. However, it is generally considered safe for those with lactose intolerance. This is because blue cheese has a low lactose content, ranging from 0% to 2.5%.
Lactose intolerance is a condition that affects a person's ability to digest lactose, a natural sugar found in dairy products. It is not an allergy, but rather an evolutionary mechanism that develops as people age, weaning them off breast milk. While it is a common condition, it is important to note that it is not a complete inhibition of lactose digestion. Those with lactose intolerance can usually handle at least one serving of low-lactose foods daily, and often more.
The amount of lactose in blue cheese is comparable to other hard cheeses such as cheddar, colby, Swiss, mozzarella, and Monterey Jack, which are considered virtually lactose-free. Blue cheese is also similar in lactose content to Swiss cheese (0-3.4% lactose) and Gouda (0-2.2% lactose). These cheeses are generally well-tolerated by those with lactose intolerance, especially when consumed in moderation.
It is worth noting that some people with lactose intolerance may still experience discomfort after consuming blue cheese. This could be due to individual variations in tolerance levels or other factors such as allergies to milk proteins. Additionally, while blue cheese is generally safe, it is always advisable for those with lactose intolerance to monitor their reactions to different foods and adjust their diets accordingly.

Blue cheese is not lactose-free
Blue cheese is a dairy product made from milk and is, therefore, not lactose-free. However, it is considered a low-lactose cheese, with a lactose content ranging from 0-2.5%. This makes it a suitable option for individuals with lactose intolerance, who can typically tolerate foods with low levels of lactose.
Lactose is a sugar found in dairy products that can be difficult for some people to digest. Lactose intolerance occurs when the body does not produce enough of the enzyme lactase, which is responsible for breaking down lactose in the digestive system. The severity of lactose intolerance can vary, and some people may be able to tolerate small amounts of lactose without experiencing any adverse effects.
Blue cheese is created through a specific production process that involves two phases. Firstly, the culturing of suitable spore-rich inocula and fermentation for maximum flavour. In this phase, a Penicillium roqueforti inoculum is prepared, which can be achieved through multiple methods. The second phase involves the addition of this inoculum to autoclaved, homogenized milk, along with salt, sugar, or both. The solution is then incubated for several days, followed by the addition of more salt and/or sugar, and further incubation.
While blue cheese has a relatively low lactose content compared to other dairy products, it is important to note that it is not completely lactose-free. Individuals with severe lactose intolerance or dairy allergies may still experience adverse reactions, such as bloating, cramping, or stomach discomfort, after consuming blue cheese. Therefore, it is always recommended to consult with a healthcare professional or a dietician to determine the appropriate dietary choices for managing lactose intolerance or dairy allergies.

Blue cheese is made in two phases
Blue cheese is a dairy product, made from cow's, sheep's, or goat's milk. It is characterised by blue, green, grey, or black veins or spots of mould throughout its body. Blue cheese is made in two phases: the culturing of suitable spore-rich inocula and fermentation for maximum, typical flavour.
In the first phase of production, a Penicillium roqueforti inoculum is prepared. This involves the use of a freeze-dried Penicillium roqueforti culture. Although Penicillium roqueforti can be found naturally, cheese producers today use commercially manufactured Penicillium roqueforti. The Penicillium roqueforti is washed from a pure culture agar plate, which is then frozen and freeze-dried. This process retains the value of the culture, which is activated when water is added.
In the second phase, salt, sugar, or both are added to autoclaved, homogenised milk via a sterile solution. This mixture is then inoculated with the Penicillium roqueforti prepared in phase one. This solution is incubated for three to four days at 21–25 °C (70–77 °F). More salt and/or sugar is added, and then aerobic incubation is continued for an additional one to two days.
After the second phase, the curds are drained and formed into wheels. The cheese is then salted to prevent spoilage and left to age for 60 to 90 days. The cheese's signature blue veins are created during the early ageing stage when the cheese is "spiked" with stainless steel rods to let oxygen circulate and encourage the growth of the mould. This process softens the texture and develops the cheese's distinctive blue flavour.
