Special Issue Information

Dear Colleagues,

Cheese is a fascinating food that has provided a means of nourishment, a way to preserve milk protein, and hedonic experiences to humankind from time immemorial. Through the ages, a wide variety of cheese flavours, textures, and shapes have evolved from the unique raw material, milk, as a result of human craftsmanship. Nowadays, science is needed to bring new light—and new opportunities—into the world of cheese.

Over the last few decades, much has been learnt about the (bio)chemical and physical phenomena that give rise to most varieties of cheese, the impacts of its microbiota on said phenomena, and the impact of cheese microbes on consumer health. However, much remains to be discovered, and many of the exciting recent publications in this area have left several questions unanswered.

Contrary to other dairy products, the cheese market has expanded, and this growth is expected to continue. Research-based innovation is needed to support this increasing trend. Furthermore, cheese is inextricably linked to the culture of the society that manufactures and consumes it, with numerous artisan varieties throughout the world acting as a valuable cultural element and source of revenue for local communities. Ensuring the sustainability of cheese production is, therefore, also important to help these traditions cope with the challenges of the current competitive markets. Research is crucial if this goal is to be achieved.

This Special Issue aims to collect research that can contribute to addressing the abovementioned aims. Your valuable contributions are welcome!

Artisanal cheeses face unique challenges due to changes in the present approaches to food safety, health, and environmental sustainability. This work aims at tackling such challenges in Pico cheese, by addressing outdated PDO criteria, the need to tackle coagulase-positive staphylococci (CoPS) and to promote circular economy by upgrading cheese whey. Model raw- and pasteurized milk cheeses were prepared with autochthonous lactic acid bacteria (LAB) as inoculants and analyzed for their composition, proteolysis, and microbiological parameters. CoPS were isolated and the risks they pose in terms of One Health evaluated by assessing phenotypic virulence factors and antibiotic resistance patterns. To assess the potential of autochthonous LAB for controlling CoPS, a challenge test was performed. Probiotic requeijão was prepared using autochthonous LAB as inoculants for upgrading whey. This work confirmed the need to update Pico cheese specifications regarding proteolysis indexes. Biofilm production was present in all Pico cheese CoPS, but resistance was only found against penicillin and cefoxitin. Adding salt or extending maturation time up to 60 days did not afford the desired level of CoPS control. Lactococcus lactis L1C21M1, however, was able to keep CoPS populations at 3 log cfu g−1 in the challenge test. Requeijão was a suitable substrate for probiotic autochthonous Lactococcus lactis L3A21M1 and L3B1M7. Full article

As consumer demand for low-salt diets increases, the development of low-salt cheese has emerged as a prevailing trend. To gain a deeper insight into the effects of salt reduction on cheddar cheese, this study used cheddar cheese with a 2.0% salt concentration (full salt, FS) as the standard control, exploring the differences in quality and composition between cheddar cheese with a 1.5% salt concentration (reduced salt, RS) and a 1.0% salt concentration (half salt, HS). The results revealed that, while the RS group exhibited significant differences in texture compared to the FS group, their physicochemical composition and microbial communities were similar, resulting in a product with quality comparable to traditional cheese. In contrast, the HS group differed notably from the FS group in terms of its physicochemical composition, texture, and microbial communities. Shifts in the microbial community within the HS group promoted enhanced protein metabolism, producing a substantial increase in free amino acids and volatile flavor compounds. In summary, cheddar cheese with a 1.5% salt concentration is similar to traditional varieties in terms of quality, while the 1.0% salt variety displays a more complex composition, due to microbial community shifts facilitating protein metabolism.

Camembert is a type of surface-mold-ripened soft cheese traditionally produced from cow’s milk. Buttermilk, a by-product of butter production with beneficial nutritional and technological properties, is increasingly being used in various applications, including cheesemaking. Therefore, this study aimed to use sweet buttermilk (BM) in combination with milk at concentrations of 10% (w/w) (BM10) and 20% (w/w) (BM20) for the production of Camembert-type cheese. A control cheese made entirely from milk was also produced. The cheese samples underwent a 28-day ripening process during which their composition, acidity, water activity, color, and sensory properties were examined at 1-week intervals. The microstructure of the matured Camembert-type cheese samples was analyzed using scanning electron microscopy (SEM), and their texture was evaluated. The production yield of BM20 cheese (18.03 ± 0.29 kg/100 kg) was lower (p < 0.05) than that of the control (19.92 ± 0.23 kg/100 kg), with BM10 showing the distinctly lowest yield (14.74 ± 0.35 kg/100 kg). The total solid and fat content of BM Camembert-type cheese samples was lower than the control. However, the total protein content in cheese BM20 at the end of the ripening period was the same as that of the control. The changes in acidity in all samples were typical for Camembert cheese, and water activity was high (above 0.92). The sensory properties of all samples were characteristic of the cheese type, while the color of BM cheese samples differed from the control. The microstructure of BM10 and BM20 cheese variants was similar, namely homogenous and less porous compared to the control. In terms of texture, the BM samples had significantly lower hardness, adhesiveness, and gumminess. This study indicates that sweet BM, particularly at a concentration of 20%, may be effectively used in the production of Camembert-type cheese. Full article

This review contributes to the knowledge on the complex and adaptive microbial ecosystems within cheese, emphasizing their critical role in determining cheese quality, flavor, and safety. This review synthesizes the current knowledge on the microbial interactions and the dynamics of lactic acid bacteria (LAB), encompassing both starter (SLAB) and non-starter (NSLAB) strains, which are pivotal to the curd fermentation and ripening processes. The adaptability of these microbial consortia to environmental and technological stressors is explored, highlighting their contributions to acidification, proteolysis, and the development of distinctive organoleptic characteristics. Historical and technological perspectives on cheesemaking are also discussed, detailing the impact of milk treatment, starter culture selection, and post-renneting procedures on microbial activity and biochemical transformations. This review underscores the importance of microbial diversity and cooperative interactions in fostering ecosystem resilience and metabolic functionality, and it addresses the challenges in mimicking the technological performance of natural starters using selected cultures. By understanding the ecological roles and interactions of cheese microbiota, this review aims to guide improvements in cheese production practices. Additionally, these insights could spark the development of innovative strategies for microbial community management. Full article
