Polpa de jambolão (Eugenia jambolana Lam.) fresca e desidratada: características físico-químicas, bioativas e funcionais, efeitos biológicos em Caenorhabditis elegans e uso para produção de frozen yogurt caprino probiótico

This work evaluated the fresh, spray dried (with 10 % of Arabic Gum) and freeze dried jambolan pulp (Eugenia jambolana Lam.) in regard to physicochemical (pH, moisture, water activity, average particle diameter, solubility and color), bioactive [total phenolic content (TPC), monomeric anthocyanin, pronathocyanidin (PA), total elagic acid (TEA), myricetin and cyanidin] and in vitro functionality (antioxidant, antienzymatic and antimicrobial activities]. In addition, the in vivo functionality of jambolan pulp was investigated using the Caenorhabditis elegans model for insulin signaling, longevity and induced neurodegeneration (Alzheimer’s disease and Parkinson’s disease related symptoms). The dried jambolan pulp presented TPC retention (50% to 75%), PA (90% to 98%), TEA (31% to 83%), myricetin (40% to 84%), cyanidin (72% to 84%) and antioxidant activity (15%). The fresh jambolan pulp, the freeze dried pulp and the spray dried jambolan pulp presented high enzymatic inhibitory activity against pancreatic lipase (4,4 to 5,8 mg/mL), alpha-glycosidase (10,3 to 13,8 mg/mL) and alpha-amylase (8,9 to 11,2 mg/mL). They also were active inhibitors against the pathogen S. aureus. The dried jambolan experimental samples were able to increase the expression of several genes linked to the insulin signaling pathways (SIR-2.1, PPTR-1, DAF-16, SOD-3, e CTL) and increased the lifespan in C. elegans (18,07 % - 24,34 %), besides decreasing the amyloid AB1-42 aggregation induced paralysis and MPP+ (1-methyl-4-phenylpyridinium) induced neurodegeneration. Based on that, the jambolan pulp and the spray dried jambolan pulp were further selected for the production of caprine frozen yogurt with the addition of Bifidobacterium animalis subsp. lactis BI-07. The final product were evaluated in regard to their physicochemical (pH, acidity, total solids, protein, total reducing sugars, fat, ashes, overrun, melting test), bioactive (TPC and monomeric anthocyanin, antioxidant activity, probiotic viability and sensory analysis (sensory acceptance). The results showed that samples with probiotic had lowest pH and higher acidity, TPC, anthocyanin and antioxidant activity. It was also observed low overrun (14.2% to 22.6%). vi Samples with probiotic had lower flavor scores. Overall, this research presents the jambolan as a highly functional bioactive-rich fruit with the potential to modulate important biological pathways, extend lifespan and retard the development of neurodegenerative diseases. Jambolan is an underexploited exotic fruit with a high colorant potential and this thesis shows for the first time in the literature important technological, biological and scientific data about this fruit that could be used towards the development of health-oriented food products.

Capacidade de adesão e formação de biofilme de Candida ssp. isoladas da cavidade oral de pacientes transplantados renais na presença do extrato de Eugenia uniflora

Candidiasis is a major oral manifestation in kidney transplant patients. Candida spp. possess essential virulence factors which contribute for the infectious process, including the ability to adhere to epithelial cells and biofilm formation. The extract obtained from the leaves of Eugenia uniflora [acetone: water (7:3, v/v)] has demonstrated antifungal activity against Candida spp. This study evaluated the influence of the extract of E. uniflora in adhesion to human buccal epithelial cells (HBEC) and biofilm formation of 42 strains of Candida spp. isolated from the oral cavity of kidney transplant patients. Candida spp. strains belonging to a culture collection were reactivated and phenotypically re-identified by classical and molecular methods (genotyping ABC and RAPD), when necessary, to complete the identification to the species level. For the virulence tests evaluated in vitro, yeasts were grown in the presence and absence of 1000 g/mL of the extract. A ratio of 10: 1 (Candida spp. cells x HBECs) was incubated for 1 hour at 37 ° C, 200 rpm, fixed with 10% formalin and the number of Candida cells adhered to 150 HBEC determined by optical microscope. Biofilms were formed on polystyrene microplates in the presence or absence of the extract. The quantification was performed with crystal violet staining at 570 nm. All isolates were viable and exhibited phenotypic characteristics suggestive of each species identified. Two strains presumptively identified as Candida dubliniensis belonged to this species as determined with genotyping ABC, while strains identified as belonging to the Candida parapsilosis species complex were differentiated by RAPD genotyping. Candida albicans was found to be the most adherent species to the buccal epithelia, while C. tropicalis showed remarkable biofilm formation.We could detect that the extract of E. uniflora was able to reduce adhesion to HBEC for both Candida albicans and non-Candida albicans Candida species. On the other hand, only 16 Candida spp. strains (36 %) showed reduced biofilm formation. However, two highly biofilm producer strains of C. tropicalis had an expressive reduction in biofilm formation. This study reinforces the idea that besides growth inhibition, E. uniflora may interfere with the expression of some virulence factors of Candida spp., and may be possibly applied in the future as a novel antifungal agent.
