          Abstract

          No Brasil, tanto a criação quanto a comercialização da carne de pato (Cairina moschata) ainda é incipiente, mas devido a sua rusticidade, fácil manejo, e carne apreciada no mercado, entende-se que a obtenção de produtos à base de carne de pato apresenta-se como uma alternativa rentável na indústria de alimentos. O uso de culturas iniciadoras na elaboração de produtos fermentados é uma prática comum na indústria de produtos cárneos estando diretamente relacionada às características de flavor, textura, cor e vida-de-prateleira do produto final. Avaliou-se o uso de culturas iniciadoras na elaboração de embutido fermentado à base de carne de pato obtida da desossa manual da coxa e sobrecoxa. Uma mistura de culturas iniciadoras de Lactobacillus plantarum BN e Kokuria varians CCT 4492 foi usada para inocular a massa cárnea. Os embutidos foram defumados em câmara para defumação a 23±1°C por aproximadamente 19 horas e curados por 25 dias. A contagem inicial de células viáveis na massa do embutido foi de 6,08Log10UFC/g e de 6,04Log10UFC/g para bactérias ácido-lácticas e Micrococcacea, respectivamente. Após o segundo dia do processo, bactérias ácido-lácticas apresentaram um crescimento de 0,79 ciclos logarítmicos e no décimo primeiro dia um aumento de 2,58 ciclos logarítmicos. O valor médio de acidez, em ácido láctico, no produto final foi de 0,39% e o valor de pH de 5,11. As análises físico-químicas apresentaram-se dentro dos padrões da legislação brasileira. O produto elaborado apresentou perfil sensorial dentro dos padrões aceitáveis de qualidade.

          Translated abstract

          In Brazil, duck raising (Cairina moschata) and duck meat commercialization are still incipient activities, but due to this animal's rusticity, easiness of management and the marketability of its meat, they may be seen as profitable alternatives in the food industry. The use of starters in the manufacturing of fermented products is a common practice in the meat industry, being directly related to the final product flavor, texture, colour and shelf life. The use of starter cultures to produce fermented sausages with a base of duck meat from the boning of thighs and real thighs was evaluated in this research. A mixture of Lactobacillus plantarum BN and Kokuria varians CCT 4492 starter cultures was used to inoculate the meat mixture. The sausages were smoked in a smoking chamber at 23±1°C for approximately 19 hours and were cured for 25 days. The initial counting of viable cells in the sausage mixture was 6.08Log10 CFU/g and 6.04Log10 CFU/g for lactic acid bacteria and Micrococcacea, respectively. Acid lactic bacteria displayed a growth of 0.79 logarithm cycles after the second day of processing, and an increase of 2.58 logarithm cycles at the 11th day. The final product acidity average value in lactic acid was 0,39%, and the pH value, 5.11. The physico-chemical analyses rested within Brazilian Legal Standards. The final product presented a sensorial profile within acceptable quality standards.

              Starters in the processing of meat products.

              Starter cultures applied in meat technology may contain moulds, yeasts and bacteria. Moulds have been selected with the primary intension to exclude any potential of mycotoxin production. Their sensory effects and the requirements of technology are also criteria for suitable starters. Their genetic potential can now be modified by genetic engineering. Yeasts are applied for sensory reasons mainly. The species in use are only fermentative and do not enhance nitrate reduction. Bacterial components of starters consist of micrococci, staphylococci, lactic acid bacteria (LAB) and, with minor importance, Streptomyces griseus or Aeromonas sp. For selection of the appropriate organisms and for ensuring optimum performance in the fermentation process, their technological, ecological, physiological and genetic properties should be well known. Most knowledge is available for LAB, which represent the most important group of starter organisms, since they are involve in the fermentation of all types of products and contribute to each single aim of the fermentation process. The study of the properties of the organisms may also contribute to reduction of potential hygienic risks not only in the classical fields of starter application but also in new fields where they may be employed as protective cultures that inhibit the growth of food pathogens or even spoilage organisms. Strains with an improved potential to reduce these risks and to exhibit further useful properties can be obtained by means of genetic engineering. Examples for successfully modified meat specific bacteria are Staphylococcus carnosus and lactobacilli L. curvatus and L. sake.
