Item Aproveitamento integral do fruto da passiflora: o maracujá em suas diversas possibilidades de consumo(2022-09-28) Costa , Maria Lúcia Gurgel da; Shinohara , Neide Kazue Sakugawa; http://lattes.cnpq.br/7105928729564845; http://lattes.cnpq.br/6658237456457369O maracujá (gênero passiflora) é um tipo de trepadeira sublenhosa cuja fruta é utilizada em diversas preparações da gastronomia brasileira e as flores e frutos são utilizadas na produção de fármacos e cosméticos. A Passiflora spp está amplamente distribuída no Brasil, região do globo considerado um dos principais centros de diversidade do gênero botânico, o que explica o amplo uso alimentar e farmacológico na cultura brasileira. O objetivo deste trabalho é explorar as diversas formas de realizar o aproveitamento integral desta espécie botânica, planta de nome científico Passiflora. Para tanto desenvolveu-se pesquisa de fontes bibliográficas e de mídia digital, e a produção de alimentos a partir do fruto desta planta, investigando as diferentes formas e receitas para o aproveitamento das diferentes partes da composição do fruto da planta, por fim são apresentadas várias formas de aproveitamento das seguintes partes da planta do maracujá: casca, sementes, polpa, arilo carnoso, entre outros. Tanto a revisão bibliográfica quanto a execução prática das produções demonstrou a versatilidade e grande possibilidade de aproveitamento desta fruta, para além do uso tradicional, em produtos como: geleia, farinha da casca, farinha das sementes, compota da casca do maracujá, Arílo Carnoso a milanesa, chá de casca de maracujá que serão descritos e apresentados ao longo deste trabalho baseados em observações, achados e substanciado por descrição da literatura científica relacionados ao tema Passiflora e suas diferentes espécies.Item Detecção sorológica de cowpea aphid-borne mosaic virus em diferentes espécies de Passiflora e caracterização biológica de um isolado obtido de Passiflora alata(2023-04-20) Gonçalves, Marcelo Henrique Oliveira; Blawid, Rosana; http://lattes.cnpq.br/5904522485457534; http://lattes.cnpq.br/3162539756953013Species belonging to the Passiflora genus are popularly known as passion fruit. They are important mainly for ornamental and medicinal use and for commercialization of their fruits in nature and for industrialization. Among the agents that cause disease in Passiflora, viruses are very important. The passion fruit woodiness disease, caused by cowpea aphid-mosaic virus (CABMV) stands out for its widespread and management difficulty. Therefore, the main objective of this work was the detection of CABMV in different species of Passiflora and the biological characterization in infected Passiflora alata plants. Seventeen samples belonging to the species of P. edulis, P. watsoniana, P. cincinnata, P. alata, P. rupestris, P. subrotunda, P. serrato-digitata, P. galbana, P. vesicaria and an ornamental hybrid cv. BRS Céu do Cerrado from a cross between P. edulis x P. incarnata showing symptoms that may be associated with viral infections. The samples were submitted to serological detection by Dot-Elisa, using specific anti-CABMV primary antibody and anti-Igg secondary antibody conjugated with alkaline phosphatase enzyme (AS-0417, DSMZ, Germany). PCR was performed using universal primers pAL1v1978 (5'GCA TCT GCA GGC CCA CAT YGT CTT YCC NGT 3') and Par1C496 (5' AAT ACT GCA GGG CTT YCT RTA CAT RGG 3') to detect co-infection with begomoviruses in four samples of P. edulis and P. alata. The isolated RPA-1 CABMV, obtained from P. alata from producing areas from Recife was analyzed by Western Blot to confirm the viral presence. In addition, the biological characterization of the isolate RPA-1 was carried out by mechanically inoculating the virus in the following species: P edulis, P. suberosa, P. vesicaria, Phaseoulus vulgaris cv. Preto 193, Glycine max, Vigna unguiculata cv CNC 0434, V. unguiculata cv. TVu 2331 and Nicotiana benthamiana. Among all samples, 76% were positive for CABMV, namely P. edulis, P. alata, P. cincinnata, P. watsoniana, P. galbana, P. subrotunda and also the ornamental hybrid cv. BRS Céu do Cerrado. No sample was positive for begomovirus infection. The isolated RPA-1 was detected by western blot for the presence of CABMV that was able to infect plants of N. benthamiana, P. edulis, P. vulgaris cv. Preto 193, but was not able to cause symptoms in Glycine max, Vigna unguiculata cv CNC 0434, V. unguiculata cv. TVu 2331. Despite this experiment lead to symptoms in P. vesicaria, it was not possible to detect the CABMV in the sample. These results may indicate that the inoculum used in the mechanical inoculation experiment may contain another virus.Item Síntese e caracterização do carvão ativado obtido da frutífera de maracujá(2024-02-26) Melo Júnior, Sebastião Batista de; Barros, Ivoneide de Carvalho Lopes; http://lattes.cnpq.br/5272867419216787; http://lattes.cnpq.br/8946175932671037The northeast of Brazil is one of the largest producers of passion fruit and produces a large amount of waste as a by-product of its activities, which has no defined destination. The accumulation of this waste without specific application causes an environmental problem, such as the fruit waste not used by pulp industries. We therefore proposed using this waste to produce biochar through the process of thermal degradation of organic matter, known as pyrolysis. After chemically activating the biochar, this material has greater chemical and thermal stability. With this in mind, priority was given to studying the properties of activated carbons from the residual biomass of passion fruit trees obtained via incipient impregnation using H3PO4 and ZnCl2. The coals were prepared from treated residual biomass (CAM/H3PO4 and CAM/ZnCl2) and the biochar precursor obtained from biomass pyrolysis (CAMB/H3PO4 and CAMB/ZnCl2). The physicochemical properties of the raw biomass, biochar and activated carbons were investigated using thermogravimetric analysis (TG/DTG), proximate analysis, infrared spectroscopy (FTIR), X-ray diffraction (XRD), point of zero charge (PCZ) and surface area (BET). FTIR data from the activated carbons showed absorptions related to C=C stretching related to aromatic structures, with the acid-activated carbons showing absorptions of phosphorus and phosphocarbon compounds (hydrogen bonded to P=O; aromatic P-O-C, and P=OOH groups), as well as confirmation of a predominantly amorphous or disordered structure identified by XRD. Thermal analysis (TG/DTG) showed that the biochar and charcoal samples activated with H3PO4 and ZnCl2 had good thermal stability. The results of the immediate analysis showed a higher content of volatile materials (72%) in the passion fruit biomass compared to the passion fruit biochar (PM) and the coals activated with ZnCl2 and H3PO4 (< 10%). The pyrolyzed materials (CAMB/H3PO4 and CAMB/ZnCl2) showed a higher percentage of fixed carbon and ash, which is to be expected given that they are materials that have undergone the carbonization process. For the coals activated with ZnCl2 and H3PO4, the zero charge point results were 3.02 and 6.42, respectively. Finally, the characterization of the surface area of each sample revealed that CAMB/H3PO4, CAM/H3PO4 and CAMB/ZnCl2 did not develop considerable porosity, with the exception of CAM/ZnCl2, which showed a surface area of 713m2.
