Avaliação do potencial antioxidante e extração subcrítica do óleo de linhaça

Abstract: O crescente mercado dos produtos naturais, aliado ao interesse dos consumidores na prevenção de doenças, tem pressionado a indústria alimentícia na busca por produtos mais saudáveis e direcionado pesquisas nesse sentido. Neste contexto, os alimentos funcionais ganharam destaque pelos efeitos bené-ficos que promovem à saúde (ANJO, 2004).Dentre os alimentos funcionais, a linhaça (Linum usitatissimum L.) é reconhecidamente uma das maiores fontes dos ácidos graxos essenciais ω-3 e ω-6, possuindo ainda vários nutri… Show more

“…In addition, it does not involve high temperatures, which can result in less loss of degradable compounds such as carotenoids and tocopherols (Coimbra and Jorge, 2012), because increased temperatures are associated with the degradation of bioactive compounds (Rodriguez-Amaya et al, 2008). The levels of oil in the pulp, ranged between 19.3 and 47.3%, indicating that the yield of oil depends on the solvent, given that some solvents are able to remove vitamins, steroids, resins and pigments as well as triacylglycerides (Galvão et al, 2008). In the kernel, the values varied from 35.4 to 46.9%.…”

“…It has been reported that vegetable oils have been used as food and for medicinal purposes for hyperlipidemia and that they may be useful adjuncts to reduce the risk of cardiovascular disease and alterations in liver metabolism. Recent studies have demonstrated that ingestion of polyunsaturated fatty acids (PUFA) present in vegetable oils, is inversely related to the incidence of heart disease by decreasing cholesterol and plasma triglyceride levels (GALVÃO et al, 2008).…”

“…Flaxseed (Linum usitatissimum L.) is characterized as growth upright plant, average height of 0.7 m and its seeds have many applications, that may be used as raw material for production of oil and bran (Galvão et al, 2008) . It is a source of essential fatty acids for human diet with benefits for human health (Millis, 2002).…”
