          Abstract

          Este trabalho objetivou avaliar a composição centesimal e aceitação de lingüiças de carne suína fabricadas com Concentrado Protéico do Soro (WPC) ou com concentrado protéico, com elevado teor de b-lactoglobulina, como substitutos da gordura. Foram realizados sete tratamentos, um grupo controle, contendo 20% de gordura, e seis tratamentos com reduzido teor de gordura, contendo diferentes níveis de adição de WPC ou de fração de b-lactoglobulina, a saber, três tratamentos com 10% de gordura e adição de três diferentes concentrações de WPC (0,2%, 0,5% e 1,0%) e três tratamentos com 10% de gordura e três diferentes níveis de concentrado protéico, com elevado teor de b-lactoglobulina (0,1%, 0,3% e 0,6%). O experimento foi realizado com cinco repetições, contendo todos os tratamentos. Foram realizadas análises em dois tempos de avaliação, um dia após a fabricação e após um período de sete dias de estocagem a aproximadamente 4°C. Foram realizadas análises de proteína (g/100g), gordura (g 100g-1), umidade (g 100g-1), estimativa de valor calórico (kcal 100g-1) e análise sensorial. Os resultados dos teores de proteína, gordura e valor calórico apresentaram diferença (P£0,05) entre o grupo controle e os demais tratamentos. Os resultados das análises de umidade e sensorial não apresentaram diferenças (P>0,05). As proteínas lácteas foram eficazes na substituição da gordura de lingüiças de carne suína, em todos os tratamentos realizados, atendendo às especificações do Regulamento Técnico de Identidade e Qualidade das Lingüiças do Ministério da Agricultura Pecuária e Abastecimento, mantendo a qualidade sensorial.

          The objective of the research was to evaluate the composition and acceptance of pork sausages manufactured with whey protein concentrate (WPC) or with protein concentrate containing high level of b-lactoglobulin (hereof called b-lactoglobulin) as fat substitutes. Seven treatments were established, a control containing 20% of fat, and six containing different levels of WPC or b-lactoglobulin addition (three treatments containing 10% of fat and 0.2%, 0.5% or 1.0% of WPC, and three treatments containing 10% of fat and 0.1%, 0.3% or 0.6% of b-lactoglobulin). Each treatment was repeated in five batches, and the samples of each batch was evaluated the first and seventh day after processing and storage at 4°C. The samples were analyzed for protein (g 100g-1), fat (g 100g-1), moisture content (g 100g-1), caloric value (kcal/g) and sensory analyses. The results of protein, fat and caloric value were different between the group control and the other treatments (P£0.05). Additionally, the moisture content and sensory analyses results showed that there was no difference (P>0.05) for the different treatments used in this experiment. The protein concentrates were efficient for the fat substitution in pork sausages, in the treatment levels used in the current experiment, complying with the specifications of the Brazilian legal requirements.
