HOLOS

A mangaba apresenta grande potencial para elaboração de fermentados alcoólicos, sendo de extrema importância o acompanhamento do processo fermentativo para obtenção dessa bebida, assim como de outras. Assim, objetivou-se acompanhar e avaliar o processo cinético de fermentação e os parâmetros fermentativos de bebidas fermentadas de mangaba. Foram elaboradas quatro formulações de fermentados com variação do teor de sólidos solúveis inicial e concentração de leveduras conforme etapas e concentrações descritas no processo de pedido de patente BR 10 2018 075834 9. Durante a fermentação, retirou-se alíquotas para o acompanhamento da cinética de fermentação e parâmetros fermentativos. Verificou-se que o comportamento cinético, com exceção do tempo de fermentação, não sofreu interferência pelas variáveis estudadas, e que a formulação 3 (maior teor de sólidos solúveis e menos concentração de levedura) e formulação 4 (maior teor de sólidos solúveis e maior concentração de levedura) apresentaram melhores resultados principalmente no tocante a teor alcoólico, concentração de etanol experimental e teórico, rendimento do processo e em produto. Conclui-se que não houve diferença no comportamento cinético, mas existiu nos parâmetros fermentativos das bebidas de mangaba.

“…The divergence data were compared with previous successful studies in individuals of the native population of Hancornia speciosa Gomes (Santos et al, 2017;Silva et al, 2017;Soares et al, 2016;Amorim et al, 2015;Costa et al, 2015;Jimenez et al, 2015;Silva et al, 2013) and BAGs Costa et al, 2011;Luz, 2016;Vitória, 2017), with the use of molecular markers.…”

Mangaba tree (Hancornia speciosa Gomes) is a tropical fruit species from Brazil and presents socioeconomic potential. The objective of this study was to determine antioxidant activity, rutin content and genetic similarity among in vivo and in vitro matrices and progenies of six accessions from the Mangaba Active Germplasm Bank of the Embrapa Coastal Tablelands, SE, Brazil. Young leaves of adult matrix plants and in vitro callus methanolic extracts obtained from young leaves resulted in differences between the accessions for the rutin content and high antioxidant activity. The Costa Azul accession, from Bahia, Brazil outstood with values above 3,000 g of dry extract/g of DPPH (2.2-diphenyl-1-picrilhydrazyl) in in vitro callus coming from nodal and internodal segments (3,023.73 and 3,136.80 g of dry extract/g of DPPH, respectively). Rutin was not found in extracts resulting from in vitro callus of mangaba tree. The difference among the values obtained for DPPH analysis are superior when compared with in vivo leaf extract, with the in vitro Costa Azul accession (nodal and internodal) outstanding, concluding that in vitro callus induction can interfere with chemical compounds of the plant. The markers detect genetic similarity under in vitro cultivation conditions. The Costa Azul accession group itself in isolation from others and EC 50 concentrations differentiated between leaf and callus are obtained. O EC 50 is superior in extracts deriving from in vitro callus, with the in vitro Costa Azul accession (nodal and internodal).

“…The first fruiting occurred in 2013, and Silva et al (2015) identified accessions whose fruits had high vitamin C content (226.63 and 244.43 mg.100 g -1 FM) and evaluated the total polyphenols (from 88.81 to 148 mg.100g -1 ) and antioxidant activity (between 3.91 and 12.20 μM Trolox/g). In 2017, with a higher number of adult plants and in the fruiting stage, Santos et al (2017) observed accessions with vitamin C content greater than 400 mg/100 g -1 FM and suggested their use in future breeding programs of the species.…”

Mangaba (Hancornia speciosa Gomes) is a fruit species native to Brazil, belonging to the Apocynaceae family. Its cultivation is predominantly extractivist and its antioxidant properties have been recently reported. The objective of this study was to evaluate the bioactive compounds and antioxidant activity in fruits of accession from the Active Germplasm Bank of Embrapa Coastal Tablelands (BI, CA, LG, PR, PT and TC). The extracts were analyzed by high-performance liquid chromatography (HPLC), which identified chlorogenic acid (93.71 - 131.66 mg.100g-1), ferulic acid (0.85 - 2.27 mg.100g-1) and rutin (238.59 -442.94 mg.100g-1). The accessions CA and PR showed the highest values of total phenols (1179.39 and 1167.05 mg GAE.100g-1, respectively). The accessions CA and TC had the highest concentration of the major compound rutin (436.78 and 442.94 mg.100g-1, respectively). Antioxidant activity values ranged from 125.95 to 158.67 g.g-1 DPPH. Principal component analysis grouped the accessions into four groups, due to the genetic variability verified in previous studies. The results will be useful to guide actions of selection and future breeding program of the species.
