- Kombucha and its dehydrated and freeze-dried derivatives: physicochemicaland microbiological characterization and in vivo toxicity evaluation Débora C. Santana Fabiany B. Danieleto Kellen O. Valdo Clarisse M. Arpini Costa Ieda C. Kalil Tadeu U. Andrade Amanda Azevedo Bertolazi Heloisi G. S. Passos Christiane M. Vasconcelos Geología SCOBY Toxicity Fermentation Phenolic compounds Caenorhabditis elegans Kombucha is a biofilm composed of a symbiotic culture of bacteria and yeast, known as SCOBY (Symbiotic Culture of Bacteria and Yeast). The SCOBY undergoes deterioration processes and loss of nutritional, bioactive and sensory attributes, which negatively impacts its shelf life. These losses can be avoided by drying methods, which help to extend shelf life and preserve the action compounds of its constituents. The objective of this study was to subject and evaluate Kombucha SCOBY to drying techniques by heat dehydration and freeze-drying. Analyses included pH, total soluble solids, total titratable acidity, turbidity, total phenolic compound content, antioxidant activity, microbiological assessment, and toxicity in vivo testing. All analyses were statistically evaluated at a 5% probability level, using SAS software. Both Kombucha beverages and dry products exhibited considerable amounts of phenolic compounds and antioxidant activity. Microorganism counts ranged from 104 to 108 CFU.ml-1 for developed beverages and products. In In vivo tests with Caenorhabditis elegans, no increase in mortality was observed, and worms fed with the fermented products showed enhanced growth. Thus, this study concludes that producing dehydrated and freeze-dried forms of Kombucha-based products is a promising and advantageous field of researchfor human health. 2024 artículo científico 0329-8922 https://www.redalyc.org/articulo.oa?id=382679692007 https://www.redalyc.org/journal/3826/382679692007/ https://www.redalyc.org/journal/3826/382679692007/html/ https://www.redalyc.org/journal/3826/382679692007/382679692007.epub https://www.redalyc.org/journal/3826/382679692007/movil 10.36995/j.recyt.2024.41.007 en http://www.redalyc.org/revista.oa?id=3826 Revista de Ciencia y Tecnología application/pdf Universidad Nacional de Misiones Revista de Ciencia y Tecnología (Argentina) Num.1 Vol.41
