Desarrollo de cultivos probióticos deshidratados por secado spray para la aplicación en alimentos. Estudios microbiológicos y tecnológicos
(Facultad de Ciencias Exactas, Universidad Nacional de La Plata, 2013)El mercado de alimentos funcionales, en particular aquellos que incorporan bacterias probióticas, se encuentra en constante expansión. La diversificación del mercado de bacterias probióticas genera la necesidad de disponer ... -
Effect of heat treatment and spray drying on lactobacilli viability and resistance to simulated gastrointestinal digestion
(Elsevier, 2012-10)Commercial probiotic bacteria are delivered mainly as frozen or freeze-dried cultures. However, spray drying is a lower cost technology that could be used for the production of probiotic cultures. In this work we aimed at ... -
Efficacy of the spray-drying treatment to inactivate the bovine leukemia virus in bovine colostrum
(Elsevier, 2020-07)Previous studies have shown the presence of bovine leukemia virus (BLV) in colostrum and milk of naturally infected cows. The relationship between virus or provirus and specific antibodies in these secretions is particular ... -
Growth of Lactobacillus rhamnosus 64 in whey permeate and study of the effect of mild stresses on survival to spray drying
(2015-09)In this study, we aimed at optimizing the growth of Lactobacillus rhamnosus 64 in whey permeate supplemented with different ingredients and we also studied the effects of mild stresses on the response to heat and oxidative ... -
Impact of native spray-dried lactic acid bacteria, packing density and wilting time on fermentation characteristics of experimental maize and lucerne silages
(Wiley, 2022-03)This study aimed at investigating the effects of an autochthonous microbial inoculant microencapsulated by spray-drying on fermentation parameters, microbiological composition, mycotoxin level and aerobic stability of maize ... -
Powdered Beverage from Native Plants from Argentina (Zuccagnia punctata and Solanum betaceum) Obtained by Spray-Drying: A Promising Source of Antioxidant Compounds
(MDPI, 2023-04)In previous studies, the Argentinean native plants called Zuccagnia punctata (jarilla, pus pus, lata) and Solanum betaceum (chilto, tree tomato) were reported as new natural sources of antioxidant compounds, mainly chalcones, ... -
Preservation of protective capacity of hyperimmune anti-Stx2 bovine colostrum against enterohemorrhagic Escherichia coli O157:H7 pathogenicity after pasteurization and spray-drying processes
(Elsevier, 2021-05)Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is a major etiologic agent that causes bloody diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome (HUS). Shiga toxin (Stx) is the main virulence factor of EHEC ... -
Spray-dried adjunct cultures of autochthonous non-starter lactic acid bacteria
(2017-08-16)Spray-drying of lactic cultures provides direct-to-vat starters, which facilitate their commercialization and use. However, this process may alter the metabolic activity and deteriorate technological features. In this work, ... -
Spray-dried Ancellotta red wine: natural colorant with potential for food applications
(Springer, 2019-10-04)Ancellotta red wine (Vitis vinifera L.) was encapsulated by spray-drying (inlet and outlet temperatures were 145 °C and 70 °C, respectively) to obtain a wine powder with a low water activity (aw) using maltodextrin DE10 ... -
Spray-drying process preserves the protective capacity of a breast milk-derived Bifidobacterium lactis strain on acute and chronic colitis in mice
(2017-02)Gut microbiota dysbiosis plays a central role in the development and perpetuation of chronic inflammation in inflammatory bowel disease (IBD) and therefore is key target for interventions with high quality and functional ... -
Study of the effects of spray drying in whey‐starch on the probiotic capacity of Lactobacillus rhamnosus 64 in the gut of mice
(2017-10)Aims: To evaluate the effects of spray drying of Lactobacillus rhamnosus 64 on its capacity to modulate the gut immune response and on the attenuation of TNBS‐induced colitis in mice. Methods and Results: Lactobacillus ... -
Study of the effects of spray‐drying on the functionality of probiotic lactobacilli
(2013-05)Three probiotic lactobacilli strains were spray‐dried in 20% (w/v) skim milk and submitted to a simulated gastrointestinal digestion. Fresh or spray‐dried cultures were administered to mice for 5 and 10 days, and Immunoglobulin ... -
Technological variables influencing the growth and stability of a silage inoculant based on spray‐dried lactic acid bacteria
(Wiley, 2020-06)Aims: To investigate the influence of different culture media and fermentation conditions on growth performance and viability of three lactic acid bacteria (LAB) strains with potential as silage inoculants, and to optimize ...
