EXTRAÇÃO DO ÓLEO, PRODUÇÃO E CARACTERIZAÇÃO DE PROPRIEDADES FÍSICAS DO BIODIESEL DE SEMENTES DE MARACUJÁ - Passiflora edulis

Abstract

Resumo: O óleo extraído das sementes de maracujá (Passiflora edulis) pode ser utilizado para diversos fins industriais, sendo aplicado na indústria de cosméticos, fabricação de tintas, sabões e outras. Mediante o incentivo dado à produção de biocombustíveis e o estudo das variadas fontes de matéria-prima nos últimos anos, o biodiesel produzido a partir do óleo extraído das sementes de maracujá, apresenta-se como viável alternativa em regiões produtoras. Para o presente estudo, as sementes de maracujá foram lavadas para retiradas dos resíduos de poupa e posteriormente secas à sombra. Elas foram prensadas mecanicamente através de prensa Ecirtec MP-40, e o óleo obtido, que possui a massa específica de 924,29 kg.m , passou pelos processos de filtragem e degomagem ácida com ácido fosfório a 5%. A produção do biodiesel foi feita por rota etílica e com o uso do NaOH como catalizador. Foram utilizados um agitador mecânico e um ultrasson no processo. Posteriormente, foram estudadas propriedades físicas como a viscosidade cinemática do combustível, onde obteve-se um valor de 4,197 mm².s EXTRACTION OF OIL, PRODUCTION AND CHARACTERIZATION OF PHYSICAL PROPERTIES OF BIODIESEL FROM SEEDS OF PASSIONFRUIT -PASSIFLORAEDULISAbstract:The oil extracted from the seeds of passion fruit (Passifloraedulis) can be used for a lot of industrial purposes, being applied in cosmetics, paints, soaps and others. Through the encouragement of biofuels production and the study of different sources of raw materials in recent years, the biodiesel produced from the oil extracted from the seeds of passion fruit, presents itself as viable alternative for producing regions. For the present study, the passion fruit seeds were washed in order to remove the leavings of fruit and subsequently dried at shadow. They were mechanically pressed by Ecirtec MP-40 and the final oil, which has a density of 924,29kg.m -3 and a kinematic viscosity of 27,918mm².s -1 was subjected to filtration process and phosphoric acid degumming 5%. The production of biodiesel was performed by ethyl route using NaOH as a catalyst. We used a mechanical stirrer and an ultrasound in the process. Thereafter, physical properties were evaluated as the kinematic viscosity of the fuel, which were 4,197 mm 2 .s -1 .

Innovative Application of Passiflora Cincinnata Seed Oil for the Cosmetics Industry

“…seed oil was 13.5 %, which confirms the efficiency of the extraction method. A similar yield (16.02%) was reported by Domingues et al (2014) who extracted oil from passion fruit seeds (Passiflora edulis) by mechanical press. The process resulted in a yellow oil with characteristic odor and color (Figure 3).…”

“…Nowadays Passiflora commercial cultivars are well systematized and serve as reference for other species, like P. cincinnata Mast. BRAGA, 2005).…”

“…Passion fruit seed oil is composed predominantly of unsaturated fatty acids, mainly oleic and linoleic, considered of high nutritional and technological value (FERRARI; COLUSSI;AYUB, 2004;LOPES et al, 2010;MALACRIDA;JORGE, 2012). Thus, this oil can be used for many industrial purposes, being applied in cosmetics, food products, paints, soaps and drugs (DOMINGUES et al, 2014).…”

The effects of microwave application on the physicochemical properties of bacaba (Oenocarpus bacaba Mart.) oil

“…The bacaba pulp used for the oil extraction had its initial moisture reduced from 38.37 ±3.65% to 10 ±1.2%, and the extraction by a hydraulic press reached a high oil yield of 19.34% (w•w -1 ). The extraction yield of the bacaba oil was above the yield obtained by passion fruit seed (16.02%) and pomegranate seed (12%) (Domingues et al, 2014;Silva et al, 2014). However, when compared to oilseeds, the extraction yield of the bacaba oil was lower than that determined by Barroso et al (2014) for brown (36.5%) and golden (35.4%) linseeds.…”
