Several medicinal plants have been administered to cancer patients attributed their anticarcinogenic and chemoprotective properties, in addition lower toxicity compared traditional therapies. The aim was investigate the antioxidant properties carotenoid composition of aqueous extracts Mentha piperita or Artemisia vulgaris which were previously found exert beneficial effects on human health through diet. exhibited potent activity. A diversity carotenoids identified these using HPLC-PDA-MS/MS....
The aim of this work was to evaluate the dynamics odors compounds in meat processing industry through microalgae-based processes.The study focused on characterization odorant profile from raw wastewater, deodorization and formation volatile organic as co-products process.The results showed that emissions wastewater treatment plant are composed 4 sulfur, 7 aldehydes, 1 furan, 2 hydrocarbon, 10 terpenes, alcohols, ketones, 3 amines, phenolic compounds.The levels these regardless polarity...
Wilson's disease is characterized by the accumulation of copper (Cu) in body and does not have a curative treatment, having high rate patients who abandon use treatment drugs. Thus, there need to raw materials from natural easily accessible sources, which mitigates consequences provides beneficial adjuvant effects. Medicinal plants are part this context, Annona muricata, better known as soursop, has widespread all around world. In present study, carotenoid profile leaves plant was assessed...
Dentre as especialidades quimicas subexploradas em microalgas, o perfil das clorofilas diferentes especies ( Chlorella vulgaris e Aphanothece microscopica Nageli ) foi caracterizado detalhes como objetivo principal deste estudo. A composicao derivados determinada por HPLC-PDA-MS (APCI + ). Os padroes de fragmentacao caracteristicos permitiram identificar oito compostos clorofila diferentes. Compostos relevância a , b moleculas derivadas reacoes feofitinizacao, epimerizacao hidroxilacao...
Os carotenoides estão entre os fitoquímicos bioativos creditados na redução do risco de doenças degenerativas, associados especialmente à ação antioxidante. Embora animais não sintetizem carotenoides, estes compostos são incorporados nos produtos gerados, como o leite, por meio da alimentação. Outra característica dos lácteos é ser uma das fontes naturais mais ricas em ácido linoleico conjugado (CLA) com propriedades também benéficas saúde, especial a gordura corporal, sendo coadjuvante no...
This study aimed to investigate the bioaccessibility of carotenoids and chlorophylls from biomass microalgae Chaetoceros calcitrans. The samples were submitted an in vitro digestion protocol, compounds determined by HPLC-PDA-MS/MS. A total 13 identified all tests. After digestion, relative ranged 4 58%. qualitative profile reflected initial sample, with all-E-zeaxanthin (57.2%) being most bioaccessible compound, followed all-E-neochrome (31.26%), latter reported for first time micellar...
Microalgae have great potential to become a new crop that could significantly impact the world's need for food in 21st century. Despite their as ingredient, microalgae social acceptance food. In addition, organoleptic traits, such aroma, are key factors humans accept part of diet. this sense, some requirements culture, species, and environmental conditions extremely important these microorganisms capable producing wide range volatile organic compounds, alcohols, hydrocarbons, esters,...
O objetivo do trabalho foi investigar o comportamento da fração volátil em diferentes fases de crescimento celular durante cultivo heterotrófico Phormidium autumnale. Os experimentos foram realizados biorreator descontínuo com aeração contínua e ausência luminosidade. compostos orgânicos voláteis isolados por microextração fase sólida no headspace, analisados cromatografia gasosa acoplada a um detector massas (SPME-GC-MS). A amostragem realizada cada 24 horas período 144 correspondendo às...
O objetivo do trabalho foi identificar os compostos orgânicosvoláteis (COVs) com descritor de aroma a partir Phormidium autumnalecultivada em resíduos agroindustriais. Os experimentos foram realizados embiorreator descontínuo aeração contínua 1VVM e ausência luminosidadecontendo 2 L água residuária abate processamento aves suínos, comrelação C/N 30, pH 7,6, temperatura 15° 25 °C, concentração inicial de100 mg.L-1. voláteis isolados headspace por microextração fasesólida, durante o tempo...
Existe um consenso mundial na indústria de alimentos que visa a substituição ingredientes sintéticos por naturais para promoção da saúde. Ao mesmo tempo, está em constante crescimento relevância industrial das microalgas como fontes extensivo espectro bioprodutos e promissoras matérias-primas produção aditivos naturais. O interesse se justifica, fundamentalmente, composição química biomassa, os carotenoides, devido suas atividades bioativas com efeitos benéficos à Esses metabólitos terem uma...
