Tommy (fictitious name, but a true story) did not pick a run-of-the-mill school science fair project, such as seeing whether plants grew better with Bach versus Metallica, powering a radio with a potato, or testing the absorbency of various paper towel brands. Tommy, one of our patients with type 1 diabetes, had a different motivation. His project was designed to test whether a simple dietary m...

Stable oil-in-water nanoemulsions were generated by ultra-high-pressure homogenization (UHPH) at 140 and 210 MPa for use as nano-vesicular vehicles (NVV) to carry hydrophobic generally recognized safe (GRAS) curcumin (CU) whey protein isolate (WPI) in aqueous nutraceutical systems. Curcumin was used its antioxidant activity participation the Michael reaction with nucleophiles pHs above 8.0. Two...

The use of antibiotics is a major problem everywhere around the globe and in step with this, there's currently an increased public scientific interest. Microbial resistance vital issue for organizations like EFSA, WHO, FDA, FAO because it developing rapidly increasingly serious health concern within world. comes as result continuous exposure microorganisms to antibiotics. Lactic acid bacteria (...

The anti-listerial activity of generally recognized as safe (GRAS) bacteriophage Listex P100 (phage P100) was demonstrated in broths and on the surface of slices of dry-cured ham against 5 strains or serotypes (i.e., Scott A, 1/2a, 1/2b, and 4b) of Listeria monocytogenes. In a broth model system, phage P100 at a concentration equal to or greater than 7 log PFU/mL completely inhibited 2 log CFU/...

In the modern world, due to overconsumption of sugar-containing products, problem obesity is relevant. Among many sweeteners that minimize sugar intake, a group sweet-tasting proteins up-and-coming. Brazzein smallest sweet (54 aa, 6473 Da), and it also safe for obese diabetic people since does not affect blood insulin levels. has high thermal stability over wide pH range: from 2 8 [1]. To incre...

Abstract This study provides an efficient alternative by extracting bioactive compounds from Haematococcus pluvialis via matrix solid-phase dispersion (MSPD) its wet form, reducing one of the process steps with greatest economic impact, drying microalga. To obtain a suitable extract for nutraceutical purposes, solvents generally recognised as safe (GRAS) designation (ethanol, ethyl lactate, and...

Archaea, bacteria, and eukarya secrete membrane microvesicles (MVs) as a mechanism for intercellular communication. We report the isolation and characterization of MVs from the probiotic strain Lactobacillus casei BL23. MVs were characterized using analytical high performance techniques, DLS, AFM and TEM. Similar to what has been described for other Gram-positive bacteria, MVs were on the nanom...

The potential of by-products generated during extra-virgin olive oil (EVOO) filtration as a natural source of phenolic compounds (with demonstrated bioactivity) has been evaluated using pressurized liquid extraction (PLE) and considering mixtures of two GRAS (generally recognized as safe) solvents (ethanol and water) at temperatures ranging from 40 to 175 °C. The extracts were characterized by ...

Dairy propionibacteria are used as cheese ripening starters, as biopreservative and as beneficial additives, in the food industry. The main species, Propionibacterium freudenreichii, is known as GRAS (Generally Recognized As Safe, USA, FDA). In addition to another dairy species, Propionibacterium acidipropionici, they are included in QPS (Qualified Presumption of Safety) list. Additional to the...
