Resumo: | The observation that the plants have biologically active substances, mainly polyphenols, that provide benefits to health, has driven studies on the antioxidant property. Thus, considering that the agri-industrial waste from acerola also contains phenolic compounds, this study was carried out to determine the procedure for extraction of polyphenols and the antioxidant activity of their extracts. Hyidroacetone, hydroethanolic, hydromethanolic and aqueous extracts, obtained by sequential extraction procedure, combining three extraction cycles (20 minutes each one) and two temperatures (25 ± 2ºC and 50 ± 2ºC), were submitted to the determination of total phenolic and screened for their free DPPH• (1,1-diphenyl-2-picrilhidrazil) and ABTS•+ (2,2 '-azino-bis-(3-etilbenzotiazolina 6-sulfonic acid) scavenging activity and their effect on the linoleic acid peroxidation by the ferric thiocyanate method.Soybean oil with the addition of the extracts (200ppm) were submitted to anaccelerated storage test in an oven at 60°C for 28 days, where sample were taken at time intervals and analyzed for peroxide value and conjugated dienes. The extracts showed high content of total polyphenols; however, the hydroacetone extract exhibited the highest total phenolic content (5,954.2 μg catechin equivalent. mL-1). Hydroethanolic and hydromethanolic extracts exhibited good DPPH• scavenging activity (low value of EC50 and TEC50, high value of EA), good ABTS•+ scavenging capacity (1.445,1 e 1.145,5μMol TEAC/g, respectively), high percentage of inhibition of peroxidation of linoleic acid (96.12% and 91.84%, respectively). These extracts showed the ability to retard the formation of peroxides and conjugated dienes in soybean oil. The procedure involves aqueous-organic solvents, three cycles of extraction and temperature of 25°C is effective in the extraction of phenolic compounds. Although, the hydroacetone extract has exhibited the highest total phenolic content, the antioxidant action of this extract was less than shown by hydroethanolic and hydromethanolic extracts that, under the experimental conditions, exhibited the best antioxidant activity, both in model system and in soybean oil. Therefore, the agri-industrial waste from acerola can be considered as a source of natural antioxidants and can be useful in food applications in replace or in association with synthetic antioxidants. |

Assim, considerando que os resíduos gerados pela agroindústria de polpa de frutas, ainda, contém significante teores de compostos fenólicos, este trabalho teve como objetivo determinar o solvente e a temperatura mais eficiente para a extração destes fitoquímicos a partir de resíduos de acerola e avaliar o potencial antioxidante de seus extratos. Desta forma, extratos hidroacetônico,hidroetanólico, hidrometanólico e aquoso, obtidos por processo de extração seqüencial, em duas temperaturas (25 ± 2ºC e 50 ± 2ºC), foram avaliados quanto ao teor de compostos fenólicos, e a sua ação antioxidante em sistemas modelos, por meio do método da capacidade de seqüestro do radical DPPH• (1,1-difenil-2-picrilhidrazil), do radical ABTS•+ (2,2’-azino-bis- (3-etilbenzotiazolina-6-ácido sulfônico) e da inibição da peroxidação do ácido linoléico pelo método Tiocianato Férrico, bem como, em óleo de soja por meio do teste acelerado em estufa. Quanto ao teor de fenólicos, independente da temperatura usada no processo de extração, destacou-se o hidroacetônico por ter apresentado o mais elevado teor (5.954,2 μg em equivalente de catequina. mL-1). Os extratos hidroetanólicos e hidrometanólico exibiram forte capacidade de seqüestro do radical DPPH• (baixo valor de EC50 e de TEC50, alto valor de EA), elevada capacidade de seqüestro do radical ABTS•+ (1.445,1 e 1.145,5μMol TEAC/g, respectivamente), e forte proteção do ácido linoléico contra a peroxidação (96,12% e 91,84% respectivamente). Estes extratos, também, apresentaram boa capacidade em retardar formação de peróxidos e de dienos conjugados em óleo de soja. Os resultados obtidos permitem evidenciar que o procedimento envolvendo solventes orgânico-aquosos, três ciclos de extração e a temperatura de 25°C se mostrou eficaz na extração de fenólicos totais. O solvente hidroacetônico embora tenha propiciadoa extração de uma maior quantidade de fenólicos totais, a ação antioxidante deste extrato foi inferior a exibida pelos extratos hidroetanólico e hidrometanólico que, nas condições experimentais, exibiram a melhor ação antioxidante, tanto em sistema modelo como no teste acelerado em estufa. Desta forma, o resíduo agroindustrial de acerola apresenta-se como fonte de antioxidante natural, permitindo vislumbrar a sua utilização em alimentos em substituição ou em associação aos antioxidantes sintéticos.Submitted by (edna.saturno@ufrpe.br) on 2016-07-26T11:49:42Z No. of bitstreams: 1 Ana Carla da Silva Caetano.pdf: 782522 bytes, checksum: f2c222ad97acdbff5efc95970a75c528 (MD5)Made available in DSpace on 2016-07-26T11:49:42Z (GMT).
