Resumo: | The occurrence of lipid oxidation is considerade as one of the main factors that affect the quality of meat and chicken products. This process leads to sensorial changes, to lost of nutritional value, appearance of toxic compounds and the development of free radicaIs that are associated with a variety of human disordens. As an attempt of management this process, various research were developed as a purpose to isolate bioactive compounds, obtained from plant source, that had effective antioxidant activity. This approach has consumers' preference, and also could help in the prevention of diseases. This research evaluated the effect of extracts obtained from potato peel as antioxidants in chicken meat. It was developed two raw extracts (aqueous and purificated) were prepared and injected in the chicken meat, at 0,5% concentration. The samples were stored under freezing (-18°C), analyzed monthly (TBA and pH), along with samples without extract as a contraI, in the time of eight month. An analyses of pH, thiobarbituric acid rate (TBA), antioxidant activity and phenolics were conducted to determine the antioxidant action of raw extracts. The antioxidant activity was highly significant for two raw extracts, it was finded value between 84 and 94% of the inhibition, in the test of to accelerate oxidation in the fat The purificated extract showed a greater yield in the content of the phenolics. The two extracts were effective to control lipid oxidation in the chicken meat. The sensorial quality of meat was not affected by added of the purificated extract, while, the aqueous, induced a change in the fiavour, wich was not accepted by the sensory paneI. |

Na tentativa de controlar este processo, muitas pesquisas tem sido desenvolvidas, com o propósito do isolamento de fitoquímicos naturais, obtidos de diversos substratos vegetais, que possuam uma efetiva ação como antioxidantes, os quais, além de terem a preferência dos consumidores, também possuem a capacidade de atuarem como auxiliares na prevenção de doenças. Assim, este trabalho avaliou a ação de extratos obtidos da casca da batata inglesa como antioxidantes em cortes de frango. Elaborou-se dois extratos (aquoso e purificado), os quais foram injetados nos cortes de frango, na proporção de 0,5%. Armazenou-se as amostras sob congelamento (-18°C), analizando-as mensalmente (TBA e pH), juntamente com as amostras sem extrato (controle) durante 8 meses. Realizou-se análises de pH, TBA, atividade antioxidante e fenóis para avaliar a ação antioxidante dos extratos. A atividade antioxidante encontrada foi elevada para os dois extratos, encontrando-se valores entre 84 e 94% de inibição no teste da oxidação acelerada em banha. O extrato purificado apresentou um maior rendimento na extração de fenóis. Os dois extratos foram efetivos no controle da oxidação lipídica nos cortes de frango. A qualidade sensorial do produto não foi afetada pela incorporação do extrato purificado, entretanto, no aquoso, houve uma redução nos escores de sabor.Universidade Federal de Santa MariaBRCiência e Tecnologia dos AlimentosUFSMPrograma de Pós-Graduação em Ciência e Tecnologia dos AlimentosTerra, Nelcindo Nascimentohttp://lattes.cnpq.br/4871318542229253Emanuelli, Tatianahttp://lattes.cnpq.br/2165391096880394Terra, Lisiane de Marsillachttp://lattes.cnpq.br/3695292052760336Souza, Marta Alessandra de Avila2006-09-082006-09-082006-06-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfSOUZA, Marta Alessandra de Avila.
