| In this work, the influence of native starter cultures on the microbiological, physicochemical and sensorial characteristics of Milano salami type was studied. Two batches of Milano salami type were produced: Batch A, with the addition of Staphylococcus xylosus U5 and Batch B (control) without the starter culture. The Milano salami type was characterized by an important microbial activity of coagulase-negative staphylococci (CNS) that resulted in substantial growth in Batch A during the ripening with an initial count of 7.60 log cfu.g-1 and reached 9.84 log CFU.g-1 after 14 days. Bacterial enzymes that showed efficient activity under the conditions found in Milano salami type were catalase, nitrite and nitrate reductase, contributing for sensory and... |

| Micrococcaceae strains are applied to fermented sausage as starter cultures, where several members of this family are naturally found. The aim of the present work was to isolate and characterize Staphylococcus xylosus from artisanal sausages produced in South Region of Brazil. From 89 isolates presenting catalase positive and coagulase negative activities, 25 strains were selected for phenotypic characterization. Nine strains identified as Staphylococcus xylosus by API-STAPH were evaluated for their nitrate reduction capacity, which showed satisfactory growth of the strains in the presence of nitrite and sodium chloride, demonstrating their potential for use as starter cultures in fermented sausage. The strains were also evaluated through genus and... |

| The purpose of the present work was to characterize promising starter culture strains of Lactobacillus plantarum isolated from naturally fermented artisanal sausage manufactured in the northwestern region of Rio Grande do Sul state, Brazil. From 127 isolates of homofermentative, Gram-positive and catalase-negative lactic acid bacteria, ten isolates were randomly selected and the phenotypic characterization and species-specific PCR were performed. Genomic DNA from each isolated strain and from the reference strains L. plantarum ATCC 8014 and L. pentosus ATCC 8041 were amplified using two pairs of L. plantarum species-specific primers (16/Lpl and LbP11/LbP12). The results of the phenotypic characterization and species-specific PCR indicated that five out of... |

| L. plantarum, strain AJ2, was isolated from naturally fermented sausage manufactured in the Southern region of Brazil and inoculated in Milano-type salami. The lactic culture exhibited the ability of growing in the product, decreasing pH in the first seven days of fermentation/maturation and the residual levels of nitrite and nitrate, as well as peroxide and TBARS values. The inoculated sausage had the highest intensity for brightness and red color, but did not present a difference in chemical composition and fatty acid composition, compared to the control. |

| Lactic beverages containing probiotics were prepared with whole UHT milk, whey of Mozzarella cheese, soybean hydrosoluble extract and sugar. Three formulations were studied, each one containing a different combination of probiotic/starter bacteria, fermented at two different temperatures (37 and 45 °C). The aim of this work was to verify the influence of these variables on the viability of probiotic microorganisms and on the physicochemical stability of lactic beverages during storage under refrigeration (21 days at 7 °C). The results indicated that the fermentation temperature had a significant effect on the viability of probiotic bacteria. Counts for Lactobacillus acidophilus were affected by storage time, resulting appropriate after 21 days only for the... |

| In the present study, technological properties of L. plantarum strains isolated from naturally fermented sausages manufactured in the South region of Brazil were investigated in order to obtain a starter culture. The technological properties evaluated were the following: ability to growth at different pH values, at different temperatures, in different salt concentrations and in the presence of commercial curing salt, fast production of acid, determination of D - and L - lactic acid; nitrate reductase activity; antagonistic activity and stability of the isolated cultures after fermentation, concentration, and freeze-drying process. The isolated strains showed effectiveness to improve technological properties as starter cultures. |

| A aveia destaca-se dentre os cereais por seu teor e qualidade proteica, alta porcentagem de lipídios distribuídos por todo o grão e predominância de ácidos graxos insaturados, além de possuir altos teores de fibra alimentar, minerais e antioxidantes, responsáveis pelos efeitos benéficos à saúde humana. Devido aos seus constituintes, a aveia apresenta forte tendência à rancidez e, por esse motivo, faz-se necessária a inativação enzimática das cariopses. Na indústria, a inativação normalmente é realizada pelo tratamento hidrotérmico. Objetivou-se, com este trabalho, estudar os efeitos do processamento hidrotérmico em escala industrial sobre parâmetros de composição química, atividade enzimática, β-glicanas e compostos fenólicos solúveis totais nas frações de... |
