Special Issue Information

Dear Colleagues,

Over the last few decades, probiotics, known for their beneficial effects on gut health, have emerged as innovative ingredients in food technology. Probiotics coupled with the concept of prebiotics, such as fructooligosaccharides, have revolutionized the landscape of food technology. They are considered the most important categories of functional foods studied and available worldwide. Additionally, synbiotics, postbiotics and psychobiotics also have been introduced as other promising products with documented relevant health benefits in humans. Given the importance of the matter, this Special Issue welcomes submissions on the following topics:

  • Novel microorganisms with probiotic properties and unique advantages;
  • Microbiological and safety assessment of probiotics, prebiotics and functional foods using novel approaches;
  • Application of probiotics, prebiotics, synbiotics, postbiotics and psychobiotics in the production of novel functional foods;
  • Role of functional foods in human health;
  • Introduction and characterization of new prebiotic sources;
  • Studies dealing with genomics, proteomics and metabolomics applied to probiotics, prebiotics, synbiotics, postbiotics and psychobiotics;
  • Modulation of gut microbiota by probiotics, prebiotics and related functional foods;
  • Methods of extending food shelf life by using lactic fermentation;
  • The use of innovative pre-treatment methods to accelerate lactic fermentation;
  • Using novel drying and encapsulation technologies to maintain the viability and extend the shelf life of probiotics.

In the last decade, the production of guinea pig meat in Andean countries has increased due to the growing number of consumers of this meat. Objective: To evaluate the effect of including different doses (0.50, 1.00, and 1.50 mL) of agro-industrial substrates (molasses distillery waste) fermented with lactic acid bacteria and yeasts on productive performance, hematological profile, relative weight changes in digestive tract organs, and changes in the intestinal microbiota in guinea pigs (Cavia porcellus). Materials: A total of 300 guinea pigs, Kuri breed, aged 20 days and weighing 330 g, were distributed into 10 groups of 30 animals each. Ctrl, Control. La, substrate fermented with Lactobacillus acidophilus (8.1 × 107 CFU/mL). Kf, substrate fermented with Kluyveromyces fragilis (7.4 × 106 CFU/mL). La + Kf, substrate fermented with bacteria and yeasts; the evaluated doses were 0.50, 1.00, and 1.50 mL/animal. The indicators evaluated in the study included weight gain, health, hematological profile, relative weight of digestive tract organs, and changes in the intestinal microbiota. Results: The parameters evaluated were toxicity, productive parameters, occurrence of diarrhea and mortality, and blood profile. The results showed a significant increase in the weight of the animals consuming probiotics, especially at higher doses. Additionally, an improvement in the intestinal microbiota was observed, with an increase in beneficial bacteria such as Lactobacillus and a decrease in pathogenic bacteria. Probiotics also influenced the hematological parameters and the weight of digestive tract organs, suggesting a positive effect on the overall health of the animals. Conclusions: Supplementation with probiotics proved to be a promising strategy for improving productive performance and intestinal health in guinea pigs. Supplementation with L. acidophilus and K. fragilis significantly enhances guinea pig growth and modulates the intestinal microbiota. The combination of strains and appropriate doses maximizes benefits. These results promise applications in animal production, requiring further studies to confirm their efficacy in other species and developmental stages. Full article
