– Scientists studying three artisan British cheeses found that the microbes responsible for their distinctive flavors may also offer surprising benefits for gut health. As the cheeses matured, helpful bacteria transformed their aromas and textures while potentially producing compounds linked to reduced inflammation, cholesterol regulation, and appetite control.
Scientists have identified the bacteria that help give three British artisan cheeses their distinctive flavors, and some of those microbes may also have potential benefits for human health.
Researchers in the Food Microbial Sciences Unit at the University of Reading tracked the microbial and biochemical changes that occurred as three locally made Oxfordshire cheeses matured. Their findings suggest that some of the bacteria responsible for developing each cheese’s unique character may also be useful to the people who eat them.
Details
The study, published in ACS Food Science & Technology, focused on three varieties made by Nettlebed Creamery in Oxfordshire. These included a soft white rind cheese aged for a little more than a week, a washed rind semi-soft cheese that matures over several weeks, and a semi-hard cheese aged in hay for about nine months.
Helpful Bacteria Shape Flavor and Texture
Lead author Sabrina Longley, a PhD researcher in the Department of Food and Nutritional Sciences, said: “Good cheese is delicious, and the artisan varieties we studied are full of microbial life that could have benefits to your gut health.
Analysis
“The aging process creates more complex aromas and textures through the work of an army of helpful bacteria. The matrix of fats and proteins in the cheese may also help protect the bacteria as they travel along the digestive tract, making cheese an excellent vehicle for delivery of probiotics to the gut.”
To follow how the cheeses changed over time, the researchers collected samples at multiple stages of maturation and analyzed both their bacterial communities and chemical composition.
All three cheeses contained bacteria with recognized probiotic potential, meaning they may help support populations of beneficial microbes in the gut. Streptococcus thermophilus, which is also commonly used as a yogurt starter, remained dominant in the semi-soft and harder cheeses throughout the maturation process. Lactococcus lactis was detected in all three cheeses from start to finish.
