What You'll Learn
Cheddar cheese is a carrier of probiotic microorganisms
Probiotics are live microorganisms, such as bacteria and yeasts, that are beneficial to health, especially digestive health. They are often referred to as "good" or "helpful" bacteria because they support the gastrointestinal (GI) tract, prevent inflammation, boost immunity, reduce stress, improve mood, and alleviate conditions like allergies and diarrhea. Probiotics are most effective in natural foods, and cheese is one of the most versatile and popular food products available today.
Cheddar cheese, in particular, has been the subject of numerous studies investigating its potential as a carrier of probiotic microorganisms. Cheddar cheese has a higher pH than traditional probiotic foods like yogurt and fermented milk, providing a more stable environment for the long-term survival of probiotics. The cheese matrix and its relatively high-fat content may also offer protection to probiotic bacteria as they pass through the gastrointestinal tract.
One of the critical considerations when using Cheddar cheese as a probiotic carrier is ensuring the microorganisms can survive the lengthy ripening period of at least six months. During this time, various nonpathogenic bacteria, including Lactobacilli and Pediococci species, proliferate in the maturing cheese. The survival of these bacteria can be influenced by factors such as the cheese's physico-chemical properties and the presence of other bacterial populations.
To enhance the probiotic content of Cheddar cheese, specific strains of bacteria, such as Lactobacillus paracasei and Lactobacillus salivarius, have been added as dairy starter adjuncts. These strains, isolated from the human small intestine, have demonstrated probiotic potential and can reach high concentrations in the cheese without significantly affecting its composition or flavor. The dense matrix of cheese provides a protective environment for these probiotic cultures, increasing their chances of survival during gastrointestinal passage.
In summary, Cheddar cheese possesses characteristics that make it a suitable carrier of probiotic microorganisms. Its pH, fat content, and dense matrix contribute to the survival and protection of probiotics during their journey through the digestive system. The addition of specific bacterial strains further enhances the probiotic potential of Cheddar cheese, making it a promising vehicle for delivering health-promoting microorganisms to consumers.

Probiotic bacteria survive in Cheddar cheese
Probiotics are live bacteria and yeasts that are good for health, especially digestive health. They are often referred to as "good" or "helpful" bacteria. Probiotics are most effective in natural foods, and cheese is one of the most versatile food products available.
Cheddar cheese, in particular, may offer certain advantages as a carrier of probiotic microorganisms. Cheddar has a higher pH than more traditional probiotic foods like yogurts and fermented milk, providing a more stable environment for the long-term survival of probiotics. The matrix of the cheese and its relatively high fat content may also offer protection to probiotic bacteria as they pass through the gastrointestinal tract.
However, for Cheddar cheese to be a probiotic food, the microorganisms must be able to survive the relatively long ripening time of at least 6 months and/or grow in the cheese over this period. During the ripening process, a number of nonpathogenic bacteria, including Lactobacillus plantarum, L. casei, and L. brevis, proliferate in the maturing cheese.
Research has been conducted on the performance of Lactobacillus strains, including L. salivarius and L. paracasei, when employed as adjuncts in Cheddar cheese over 8 months of ripening. These strains had previously been isolated from the human intestine and were shown to be acid and bile-tolerant, adherent to human epithelial cells, nonpathogenic, and to have desirable antibiogram profiles. The results demonstrated that the probiotic L. paracasei species are particularly suitable for Cheddar cheese applications, as they grow to high numbers and remain at this level even after 8 months of ripening.
In summary, probiotic bacteria can survive in Cheddar cheese, and the cheese provides a protective environment for their survival and activity. The development of probiotic Cheddar cheese involves careful consideration of the processing steps and their impact on the survival of these beneficial microorganisms.

Cheddar cheese is made from raw, unpasteurized cow's milk
Cheddar cheese is a popular variety of cheese that can be made from raw, unpasteurized cow's milk. Raw-milk cheese is often made by small-scale artisanal producers, who use milk from a single herd of cows, sheep, or goats. Raw-milk Cheddar cheese is one such variety, with a smooth texture and slight fluctuations in colour, resulting from traditional artisanal crafting.
Raw-milk Cheddar cheese is made by warming the milk to an optimal temperature of around 90-102°F for culturing, without pasteurizing it. Pasteurization, the process of sterilizing milk, involves heating it to a much higher temperature of around 160°F, which can destroy many of the naturally occurring enzymes and diverse bacteria present in raw milk. These enzymes and bacteria are important for building the flavour of the cheese. Thus, raw-milk Cheddar cheese is known for its unique, complex, and well-defined flavour and aromatics, as well as its smooth texture and natural yellow colour.
In the United States, the sale of cheese made from unpasteurized milk is forbidden unless the cheese is aged for at least 60 days. This regulation was implemented to protect consumers from potentially harmful pathogens, as unpasteurized milk can become contaminated with microbes such as Salmonella, Listeria, and E. coli. However, after 60 days, the acids and salts in raw-milk cheese naturally prevent these harmful bacteria from growing.
Despite the potential risks, some cheesemakers believe that using raw milk creates more flavorful and nutritious cheeses. Raw Cheddar cheese is packed with bioavailable vitamins, minerals, enzymes, beneficial bacteria, naturally occurring CLA, and Omega-3 fatty acids. It is also easier to digest than processed cheese products, making it a delicious and natural option for those who experience discomfort with processed cheese.

Probiotics are good for gut health
Probiotics are live microorganisms, such as bacteria and yeasts, that are good for health, especially digestive health. They are often referred to as "good" or "helpful" bacteria because they support the gastrointestinal (GI) tract, prevent inflammation, boost immunity, reduce stress, improve mood, and alleviate conditions ranging from allergies to diarrhea. Probiotics have also been shown to help with serious gut ailments, such as IBS and leaky gut syndrome.
Cheddar cheese, specifically, has been the subject of studies investigating its potential as a probiotic food. Cheddar cheese has a higher pH than traditional probiotic foods like yogurt and fermented milk, which may provide a more stable environment for the long-term survival of probiotic microorganisms. The matrix of the cheese and its relatively high fat content may also offer protection to probiotic bacteria as they pass through the gastrointestinal tract.
One study added probiotic Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus paracasei, and Bifidobacterium animalis subsp. lactis to full-fat, reduced-fat, and low-fat Cheddar cheeses to study their survival over 270 days of aging. The results showed that these probiotic bacteria can survive in Cheddar cheese and modify populations of other lactic acid bacteria.
Another study investigated the performance of Lactobacillus strains, including L. salivarius and L. paracasei, when used as adjuncts in Cheddar cheese over 8 months of ripening. These strains had previously been isolated from healthy human intestines and were shown to be acid and bile tolerant, adherent to human epithelial cells, nonpathogenic, and had desirable antibiogram profiles. The results demonstrated that the probiotic L. paracasei species were particularly suitable for Cheddar cheese applications, as they grew to high numbers and remained stable even after 8 months of ripening.
It's important to note that to exert a probiotic effect, cultures must maintain their viability in food products through to the time of consumption. In the case of Cheddar cheese, this means the microorganisms must survive the relatively long ripening time of at least 6 months, or even grow during this period. Therefore, when purchasing Cheddar cheese for its potential probiotic benefits, look for labels indicating "raw," "probiotic," or "made from raw milk." Additionally, avoid cooking or melting the cheese to preserve the probiotic benefits.

Cheddar cheese has a higher pH than traditional probiotic foods
Probiotics are live bacteria and yeasts that are considered good for health, especially for the digestive system. They are often referred to as "good" or "friendly" bacteria and are naturally found in the body. Probiotics are typically associated with fermented foods, such as yogurt, kefir, and sourdough, which are known to promote digestive health, boost the immune system, and offer other health benefits.
Cheddar cheese, a popular variety of cheese, has been found to host probiotic bacteria as well. Research suggests that probiotic bacteria can survive in Cheddar cheese and can even modify the populations of other lactic acid bacteria present. This indicates that Cheddar cheese can serve as a carrier for probiotic bacteria, potentially offering health benefits to consumers.
However, it is important to note that the pH levels of Cheddar cheese differ from those of traditional probiotic foods. Milk, which is the base ingredient of cheese, typically starts with a pH of around 6.7. During the cheese-making process, varying amounts of acid are introduced, resulting in the final pH of the cheese. Cheddar cheese, in particular, tends to have a lower pH, indicating higher acidity.
On the other hand, traditional probiotic foods like yogurt tend to have a higher pH, typically falling within the range suitable for the development and screening of probiotic lactic acid bacteria, which is between 6.2 and 8.5. This range is closer to neutral on the pH scale, which goes from 0 to 14, with 7 being neutral. Therefore, it can be concluded that Cheddar cheese generally has a higher acidity and lower pH compared to these conventional probiotic-rich foods.
