Special Issue Information

Dear Colleagues,

The growing consumer interest in functional foods has propelled probiotics in dairy products to the forefront of health and nutrition research. Probiotics offer a range of health benefits, including gut microbiota modulation, immune system enhancement, and potential roles in metabolic and neurological health. Dairy products serve as an excellent medium for delivering probiotics due to their rich nutrient composition and ability to support probiotic viability.

This Special Issue aims to explore the latest advancements in probiotic dairy products, covering key aspects such as innovative processing techniques, challenges in maintaining probiotic stability, and strategies to enhance bioavailability. Additionally, we welcome research on emerging trends, consumer perceptions, and market dynamics that shape the global probiotic dairy industry.

We invite contributions from researchers, food scientists, nutritionists, and industry professionals to present original research articles, reviews, and case studies that provide insights into the development, health benefits, and commercial potential of probiotic dairy products. Topics of interest include, but are not limited to, the following:

  • Health benefits of probiotics in dairy-based foods;
  • Advances in probiotic dairy product formulation and processing;
  • Encapsulation technologies and probiotic stability;
  • Fermentation techniques for enhancing probiotic viability;
  • Regulatory aspects and safety evaluation of probiotic dairy products;
  • Consumer trends and market prospects of probiotic dairy foods.

This Special Issue aims to provide a comprehensive platform for knowledge exchange, fostering interdisciplinary discussions that bridge food science, microbiology, and market analysis to advance the field of probiotic dairy research.

Probiotics like Lactobacillus rhamnosus GG (LRGG) offer health benefits but face reduced viability under harsh gastrointestinal (GI) conditions. Encapsulation improves stability, yet most studies rely on static GI models with a simplified environment that may overestimate survival. This study assessed LRGG survival using chitosan-coated alginate beads under both static and dynamic GI models, including peristaltic flow and continuous juice replenishment. Food matrices (casein, corn starch, and soybean oil) were tested in static models. Beads were prepared via extrusion and subjected to simulated gastric and intestinal digestion. After 2 and 4 h of digestion, casein preserved LRGG viability at 8.50 ± 0.11 Log CFU/g, compared to 5.81 ± 0.44 with starch and undetectable levels with soybean oil. Casein’s protective effect was attributed to its pH-buffering capacity, raising gastric pH from 2.5 to 4.6. Starch offered moderate protection, while soybean oil led to bead dissolution due to destabilization of the egg-box structure. Dynamic GI models showed greater reductions in LRGG viability than static models, emphasizing the need for physiologically relevant simulations. The results highlight the importance of selecting appropriate food matrices and digestion models for accurate probiotic assessment, supporting improved encapsulation strategies in functional food development.
