Methods, which use an indirect plasma treatment for the inactivation of microorganisms in foods, claim a vastly growing field research. This paper presents method that uses plasma-processed air (PPA) as sanitizer. In addition to sanitation concept decontamination produce value chain, presented offers possible application “in-process” surface sanitation. PPA provides antimicrobial-potent species...

Background: The application of natural antimicrobial and antioxidant agents in food pharmaceutical products has recently become a trend due to the high demand for them from consumers. Postbiotics are bioactive compounds that produced when healthy bacteria gut ferment fiber. Objectives: This study aimed compare antibacterial properties postbiotics 5 different lactic acid (LAB) including Lactipla...

Contamination of kitchen surfaces, during food preparation, due to bacteria present in foodstuff is one of the main causes of foodborne outbreaks. Cells adhered to those surfaces of domestic kitchens are not easily removed by normal cleaning procedures. Therefore, they can be a source of contamination for other foods and objects. Several studies indicate that various pathogenic bacteria like Li...

Murine T cells generated against heat-killed Listeria monocytogenes or Listeria intracellular product (LIP) were propagated in a source of Interleukin 2. Both T-cell cultures were greater than 98% Lyt 1+, 2/3- and proliferated specifically against LIP and L. monocytogenes crude whole-cell antigen in vitro. Proliferation of both T-cell cultures required the presence of antigen and accessory cell...

During this research 159 samples of ready-to-eat and precooked food were examined for the detection of Salmonella spp., Listeria monocytogenes, Escherichia coli, coagulase-positive staphylococci and Enterobacteriaceae, bacterial count. All samples were negative for Salmonella spp. and Listeria monocytogenes; although a low count of coagulase-positive staphylococci (no. 5 samples) and E. coli (n...

Human-monocyte-derived dendritic cells (MoDC) are very efficient in the uptake of Listeria monocytogenes, a gram-positive bacterium which is an important pathogen in humans and animals causing systemic infections with symptoms such as septicemia and meningitis. In this work, we analyzed the influence of blood plasma on the internalization of L. monocytogenes into human MoDC and compared the upt...

O consumo de alimentos com propriedades antioxidantes desempenha um papel importante para a saúde. A principal função deles é eliminação radicais livres, produzidos pelas espécies reativas oxigênio. Na indústria alimentos, os extratos plantas ricas em compostos fenólicos podem ser usados como aditivos nutracêuticos ou conservantes naturais aumentar vida prateleira dos industrializados. Dessa fo...
