A polymerase chain reaction (PCR) assay was developed and compared with standard methods for rapid detection of Burkholderia cepacia, a major industrial contaminant, in cosmetic and pharmaceutical raw materials and finished products. Artificially contaminated samples were incubated for 24 h in trypticase soy broth containing 4% Tween 20 and 0.5% soy lecithin. DNA was extracted from each sample ...

stance. Unfortunately, identification of the responsible agent is not as straightforward as it appears. We report here a case we encountered recently. A &yearold woman with a long history of reactive airway disease and peanut and soy allergies was admitted for treatment of an anaphylactic reaction after inadvertently ingesting peanut oil at a party. Her initial systemic reaction was treated suc...

The effectiveness of free and nanovesicle-encapsulated nisin to control Listeria monocytogenes in Minas Frescal cheese was investigated. Commercial nisin was encapsulated into liposomes of partially purified soy lecithin. Free (0.1 mg/mL and 0.25 mg/mL) and nanovesicle-encapsulated nisin (0.25 mg/mL) were applied onto the surface of cheese samples, and L. monocytogenes was inoculated before inc...

The moisture levels in sausages that were stored for 16 days and added with different concentrations of orange extracts to a modification solution assessed using response surface methodology (RSM). Among the 32 treatment matrixes, 10 presented higher content than 19. Spectral pre-treatments employed enhance model’s robustness. raw pre-processed spectral data, as well content, fitted regression ...

A commercial casein hydrolysate was microencapsulated in liposomes produced with non-purified soy lecithin, cryoprotected with two different disaccharides and lyophilized. The encapsulation efficiency of casein hydrolysate ranged from 30 to 40%. The powders were analyzed by differential scanning calorimetry (DSC), scanning electron micrography (SEM), infrared spectroscopy (FTIR) and wide angle ...

H The purpose of this study was to investigate the effects of polyunsaturated phosphatidylcholine (PPC) in NT FactorTM* on aging, in general, and ageassociated hearing loss, in specific. Additionally, this brief report supports that the Membrane Hypothesis of Aging (MHA) provides a plausible explanation for agerelated hearing loss. According to this hypothesis, which is also known as the Mitoch...

Lipid matrices are always an interesting alternative to encapsulate hydrophobic bioactives, as many of them have their absorption enhanced in the presence of lipidic molecules. Among the most studied hydrophobic food ingredient are the carotenoids, known by their prominent antioxidant capacity, and, among them, the beta-carotene is the nutritionally most active one. In this study liposomes (pho...

The formulation of a potential delivery system based on liposomes (Lips) formulated from soy lecithin (SL) for paclitaxel (PTX) was achieved (PTX-Lips). At first, PTX-Lips were prepared by thin film method using SL and cholesterol and then were characterized for their physiochemical properties (particle size, polydispersity index, zeta potential, and morphology). The results indicated that PTX-...

Novel solid lipid nanoparticles (SLNs) were developed to improve oral bioavailability of oxyresveratrol (OXY). The SLNs were prepared by a high speed homogenization technique, at an effective speed and time, using Compritol 888 ATO (5% w/w) as the solid lipid. The appropriate weight proportions (0.3% w/w) of OXY affected the physicochemical properties of blank SLNs. The effects of surfactant ty...
