Resumo: | Given PSE meat’s high incidence, the need to reduce sodium in food processed products and the sodium chloride’s (salt) assistance to correct eventual defects caused by PSE meat, this research aimed to evaluate cured smoked pork loin formulated with several PSE meat and salt contents in order to establish the highest PSE meat content and the lowest salt content capable of preserving the product’s characteristics. We used a 2x2 Central Composite Design (CCD). We analyzed chemical composition, sodium content, weight losses, pH, TBARS index, water activity (Aw), objective color (L*, a*, b*, C* and h*), texture profile analysis, sliceability and optimal salt sensory evaluation of the products through response surface methodology, whereas sensory acceptance was analyzed through internal preference map (IPM). The response surface model was not significant (P > 0,005) for cooking loss, syneresis, freezing loss, L*, a*, b*, cohesiveness and flexibility, pointing that PSE meat and salt contents do not affect those variables. Protein content, TBARS index, h* and C* were adjusted, but presented low determination coefficients (R 2 ). Chemical composition and sodium content followed the behavior predicted from the raw material composition. The Aw was influenced only by salt content, being lower as higher amount of salt were used. The pH and heating loss were more affected by PSE meat content, wherein pH was lower and heating loss was higher when higher PSE meat was used; both parameters were lower as the salt content was higher. The remaining analyses were influenced mainly by salt content: expressible moisture, hardness, chewiness, adhesiveness and sliceability were higher when salt content was higher and PSE meat content was lower. The sensory test pointed that optimal salt addition was approximately 0,5% for this specific formulation. IPMs pointed the formulations containing 100% PSE meat 1% salt, and 50% PSE meat 0% salt as the least accepted by consumers. Salt content is essential for the product’s quality maintenance when PSE meat is used. When PSE meat was used the formulation should be added at least 1% of salt. However more tests are required to determine maximum PSE meat content which does not affect cured-smoked-pork-loin acceptance. |

Foi utilizado um delineamento composto central rotacional (DCCR) 2x2. Composição centesimal, teor de sódio, perdas de peso, pH, índice de TBARS, atividade de água (Aa), cor objetiva (L*, a*, b*, C* e h*), perfil de textura, fatiabilidade e teste sensorial do ideal de sal dos produtos foram analisados pela metodologia de superfície de resposta, enquanto a aceitação sensorial foi analisada por mapa de preferência interno (MPI). O modelo de superfície de resposta não foi significativo (P>0,05) para perda de peso por cozimento (PPC), sinerese, perda de peso por ciclos de congelamento (PCC), L*, a*, b*, coesividade e flexibilidade, indicando que os teores de carne PSE e sal não interfiram em tais variáveis. O teor de proteínas, índice de TBARS, h* e C* foram ajustados, mas apresentaram baixos coeficientes de determinação (R 2 ). A composição centesimal e o teor de sódio seguiram o comportamento previsto diante da composição das matérias-primas adicionadas. A Aa foi influenciada apenas pelo teor de sal, reduzindo quando maiores quantidades de sal foram utilizadas. O pH e a perda de peso por reaquecimento (PPR) foram mais afetados pela quantidade de carne PSE, tendo o pH caído e a PPR aumentado à medida que maiores quantidades de carne PSE foram adicionadas; ambos os parâmetros foram reduzidos com maiores teores de sal. As demais análises foram influenciadas, principalmente, pelo sal: perda de peso por exsudação (PEX), dureza, mastigabilidade, adesividade e fatiabilidade aumentaram com o uso de maiores teores de sal e menores proporções de carne PSE. Pelo teste do ideal, para a formulação utilizada, a adição ideal de sal foi de, aproximadamente, 0,5%. Os MPI indicaram que as formulações com 100% PSE e 1% de sal e com 50% PSE e 0% de sal foram as menos aceitas pelos provadores. A quantidade de sal é essencial para a manutenção da qualidade do produto quando é utilizada a carne PSE, sendo que produtos que utilizam carne PSE na formulação devem ser adicionados de, no mínimo, 1% sal. Porém, são necessários mais testes para determinar a proporção máxima de carne PSE que não afete a aceitação dos lombos tipo canadense.Universidade Federal de LavrasPrograma de Pós-Graduação em Ciência dos AlimentosUFLAbrasilDepartamento de Ciência dos AlimentosRamos, Eduardo MendesRamos, Alcinéia de Lemos SouzaFontes, Paulo RogérioCunha, Simone de Fátima Viana daSilva, Gabriela de Barros2016-03-17T12:48:44Z2016-03-17T12:48:44Z2016-03-172016-02-22info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfSILVA, G. de B.
