Modeling the effect of Croton blanchetianus Baill essential oil on pathogenic and spoilage bacteria.

This study aimed to evaluate and model the antimicrobial action of different concentrations of Croton blanchetianus essential oil (CBEO) on the behavior of six bacterial species in vitro. CBEO extraction was performed by hydrodistillation and characterized by CG-MS. CBEO solutions in culture media were tested at 0.

Cashew apple ( L.) extract from a by-product of juice processing: assessment of its toxicity, antiproliferative and antimicrobial activities.

Cashew apple extract (CAE) is a product with intense yellow color obtained from residual fibers of juice processing. Although CAE is known to be rich in carotenoids and anacardic acids, the biological activities of this potential natural food colorant remain unexplored. The present study is the first to investigate the toxicity, antiproliferative and antimicrobial activities of the lyophilized CAE (L-CAE) and its encapsulated products, using maltodextrin (M-CAE) or cashew gum (CG-CAE) as carriers.

Eco-friendly synthesis of an alkyl chitosan derivative.

Chitosan (CH) was N-alkylated via Schiff base formation and further reduced via sodium borohydride. The reaction was carried out at room temperature, in a homogeneous aqueous medium, using as a source of alkyl group an essential oil (Eucalyptus staigeriana) containing an unsaturated aldehyde (3,7-dimethylocta-2,6-dienal). Derivatives were characterized by Infrared Spectroscopy, proton and carbon Nuclear Magnetic Resonance, XRD, particle size distribution and zeta potential.

Noni (Morinda citrifolia L.) fruit as a new source of milk-clotting cysteine proteases.

This work reports the characterisation of caseinolytic and milk-clotting activities of proteases extracted from ripe fruits of Morinda citrifolia L., as a potential of their use in cheese production. Noni puree extract (NPE) was obtained by homogenising the fresh puree in 150 mM NaCl/50 mM sodium phosphate buffer (pH 7.

Graviola Fruit Bar Added Acerola By-Product Extract Protects Against Inflammation and Nociception in Adult Zebrafish ().

Studies involving foods associated with pain reversal and anti-inflammatory effects using zebrafish are rarely reported in the literature. This study aimed to evaluate the effect of graviola ( L.) fruit bar (GFB) and GFB added with acerola ( L) seed extract (ASE) on acute nociception and abdominal inflammation in adult zebrafish (.

Electrochemical immunosensors for Salmonella detection in food.

Pathogen detection is a critical point for the identification and the prevention of problems related to food safety. Failures at detecting contaminations in food may cause outbreaks with drastic consequences to public health. In spite of the real need for obtaining analytical results in the shortest time possible, conventional methods may take several days to produce a diagnosis.

[Salmonella sp and Listeria monocytogenes in fully cooked ham commercialized in supermarkets of Fortaleza (CE, Brazil): risk factor for public health].

The objective of this work was to evaluate the occurrence of Salmonella sp. and Listeria spp. in fully cooked ham without fat cover, stored under refrigeration, commercialized in supermarkets of Fortaleza (CE, Brazil).
