摘要：Personalized dietary supplements adapted to the individual needs of athletes and the elderly enriched with microbial propionic acid were produced in form of a powder, ready to be mixed in drinks such as orange juices. Studies have shown that fresh and pasteurized orange juices have a positive influence on gut microbiota, and exhibit selective prebiotic activity, particularly in terms of gut microbiota, by increasing Lactobacillus spp., Enterococcus spp., Bifidobacterium spp., and Clostridium spp., and reducing Enterobacteria. Besides, studies been reported the effect of the combined use of probiotics and organic salts, such as propionic acid salts, on the in vitro inhibition of microorganisms. Additionally, the short chain fatty acid propionic acid influences the gut-mediated immune regulation of people, reduces lipogenesis, and inhibits serum cholesterol synthesis.
