Abstract BRS Manicoré cultivar is an interspecific hybrid between Elaeis oleifera and Elaeis guineensis(ISH OxG). It has shown high yield potential and genetic resistance to phytosanitary problems in cultivation in Brazil. Studies have indicated differences in the composition of ISH OxG and palm oils, as well as the influence of genotype and environment on palm oil characteristics. The aim of this study was to assess the distribution of fatty acids, carotenoids, and tocochromanols in the olein and stearin fractions of the oil produced by the ISH OxG cultivated in municipality of Una, state of Bahia, Brazil by liquid and gas chromatography. There were significant differences for fatty acids, carotenoids and total tocochromanols between olein and stearin (p<0.05). The olein was richer in oleic acid (59% vs 57%), while stearin was higher in saturated fatty acids (31% vs 29%), alpha and beta-carotene (232 vs 213 mg/Kg, and 347 vs 299 mg/Kg, respectively), alpha-tocotrienol (136 vs 90 mg/Kg), and alpha-tocopherol (52 vs 32 mg/Kg). No difference was observed for gamma-tocotrienol (598 – 450 mg/kg) and delta-tocotrienol; nonetheless, the high content of the former in both fractions was notable. The ISH OxG oil fractions showed distinct patterns, indicating different applications.

Resumo BRS Manicoré é um híbrido interespecífico entre Elaeis oleifera e (ISH Elaeis guineensisOxG). Em cultivo no Brasil, BRS Manicoré demonstrou alto potencial produtivo e resistência genética a problemas fitossanitários. Estudos têm indicado diferença na composição do óleo dos ISH OxG e da palma de óleo, bem como a influência do genótipo e do ambiente nas características do óleo de palma. O objetivo deste trabalho foi determinar a composição em ácidos graxos, carotenoides e tococromanóis das frações oleína e estearina do óleo produzido a partir do ISH OxG cultivado em Una, Bahia, por cromatografias líquida e gasosa. Houve diferença significativa nos ácidos graxos, nos carotenoides e nos tococromanóis entre oleína e viestearina(p<0,05). Os resultados confirmaram maiores teores de ácido oleico (59% vs 57%) e de ácidos graxos saturados na oleína (31% vs 29%) e maior concentração de e alfa e beta caroteno (232 vs 213 mg/Kg e 347 vs 299 mg/Kg, respectivamente),alfa-tocotrienol (136 vs 90 mg/Kg) e alfa-tocoferol (52 vs 32 mg/Kg) na estearina; não foi observada diferença significativa em gama-tocotrienol (598 – 450 mg/kg) e delta-tocotrienol; entretanto,ressalta-se o elevado teor do primeiro em ambas as frações. O fracionamento de HIE OxGoriginou frações com características distintas e diferentes possíveis aplicações.

Abstract The Brazilian food industry and government reached a consensus on progressively reducing the content of industrial trans fatty acids (TFA) in food products due to its health effects. French fries are popular among young people and this study evaluates four brands of frozen pre-fried French fries marketed in Brazil and four brands of French fries from the main fast-food chains in Brazil regarding their fatty acid profile and total fat content. The total fat content of fast-food chain French fries was 14-21g/100 g, with a total TFA content of 0.01-0.14 g/100 g. In turn, the total fat content of frozen pre-fried French fries ranged from 3.3 to 7.4 g/100 g, with a total TFA content of 0.01-0.03 g/100 g. Deep fat frying of these products did not include partially hydrogenated fat. Two most sold pre-fried French fries brands available in Rio de Janeiro city, Brazil were selected and evaluated using air frying cooking method regarding sensory acceptance. Mean acceptance among consumers was 5.7 and 5.1 for brands A and B, respectively. Brand A was further evaluated by children and young people, with mean acceptance of 4.48 and 7.2, respectively, showing good acceptance for pre-fried French fries with reduced fat content.

Abstract The passion fruit juice production generates around 70% of by-products comprising rind, seeds and arils that are commonly discarded. The seeds consist of 4% of fruit weight with the potential to produce around 2,500 ton/year of high added-value oil in Brazil. In this work, passion fruit seeds from different juice manufacturers and the effect of the seed moisture were evaluated towards oil quality and extraction efficiency, using a continuous expeller press of 100 kg/h capacity. The seeds were washed and dried before pressing. The main fatty acids detected were linoleic (67% to 68%), oleic (16% to 17.4%) and palmitic (11%). The oil quality and oil recovery depended on the seed oil content, i.e., the seed moisture before pressing and the different provenances of the seeds. Significant differences were observed for oxidative stability, acidity and conjugated dienes (p < 0.05) for oils from different fruit juice manufacturers. Among them, only one met the requirements of Brazilian regulation regarding oil acidity (less than 2%), thus indicating the need for an effective waste treatment process after juice extraction. Regarding the seed moisture, the highest Oil Stability Index (OSI) (7.4 h) and lowest free fatty acid content (0.63%) were obtained for the oil from the lowest seed moisture content. The oil recovery varied from 78% to 89% and the cake oil content was lower than 8% showing the elements of the feasibility of the process to obtain good quality oil.

Resumo A produção de suco de maracujá gera cerca de 70% de coprodutos compostos de casca, sementes e arilos, que costumam ser descartados. As sementes consistem em 4% do peso do fruto, com potencial para produzir em torno de 2.500 ton/ano de óleo de alto valor agregado, no Brasil. Neste trabalho, sementes de maracujá de diferentes fabricantes de suco e o efeito da umidade das sementes foram avaliados quanto a qualidade do óleo e eficiência de extração, utilizando uma prensa contínua (expeller) de 100 kg/h de capacidade, sendo que as sementes foram lavadas e secas antes da prensagem. Os principais ácidos graxos detectados foram linoleico (67% a 68%), oleico (16% a 17,4%) e palmítico (11%). A qualidade do óleo e o rendimento do processo dependeram do teor de óleo da semente, da umidade da semente antes da prensagem e das diferentes procedências das sementes. Diferenças significativas foram observadas para estabilidade oxidativa, acidez e dienos conjugados (p<0,05) para óleos obtidos de sementes de diferentes fabricantes de sucos de frutas. Dentre estes, apenas um atendeu aos requisitos da regulamentação brasileira quanto à acidez do óleo (menos de 2%), indicando a necessidade de um processo eficaz de tratamento de resíduos após a obtenção do suco. Em relação à umidade da semente, o maior índice de estabilidade do óleo- OSI (7,4 h) e o menor teor de ácidos graxos livres (0,63%) foram obtidos para o óleo a partir da semente de menor umidade. A recuperação de óleo variou de 78% a 89% e o teor de óleo da torta foi inferior a 8%, mostrando a viabilidade do processo para obtenção de óleo de boa qualidade.
