Cím:	Comparative study on prebiotic activities of various dietary fibers on distinct probiotics / Attila Kiss, Erzsébet Karaffa, Károly Pál, Ferenc Peles
Dátum:	2023
Megjegyzések:	More and more up-to-date studies underpin the relevance of versatile dietary fibers in terms of optimizing balance of intestinal microflora and promoting gut's health, as well as overal human health. Most of the available research results stated that prebiotic materials facilitate the activity and the reproduction of probiotic bacteria. At the first stage of the study inulin was used as model prebiotic, and its impact on activity of distinctive probiotics (Bifidobacterium lactis, Bifidobacterium breve, Lactobacillus acidophilus, Lactobacillus rhamnosus) has been assessed. The actual behavior of probiotics can properly be predicted by the application of artificial digestion models, thus the prebiotic effect of several potential food components (chicory, inulin, fructo-oligosaccharides, resistant starch, dahlia, Ganoderma, fenugreek) were investigated. The simplified model includes sterile flasks with enzyme at 37 ?C and pH adjusted to 6.8 in anaerobic conditions. The probiotic strains, mentioned above, were added to the model system. The change in the composition of the microbial material was determined by applying a plating technique. The results show that inuline of synergy type and inuline of chicory root exhibited the most outstanding prebiotic activities regarding all the 4 investigated probiotic strains. Resistant starch variants may also contribute to the enhancement of the prebiotic characteristics. Interestingly application of combinations of resistant starches and inuline led to enhanced prebiotic activities in cases of Bifidobacterium lactis, Bifidobacterium breve. The investigated honey and biscuit matrices tend to reduce the observed prebiotic activity of both fructans and Ganoderma. Fenugreek has not displayed marked prebiotic effect on any of the examined strains. Apparently there is a great potential in the food industry for the application of blends of distinctive prebiotics.
