The copolymers of N-vinyl-2-pyrrolidone and methacrylonitrile (V/N) were prepared by free radical bulk polymerisation. The copolymer composition was determined from the quantitative 13C{1H} NMR spectrum. The reactivity ratios for N-vinyl-2-pyrrolidone (V) and methacrylonitrile (N) were found to ...
The cationic half-sandwich aqua-complexes [(η5-C5Me5)M(PP∗)(H2O)][SbF6]2 [M = Rh, Ir; PP∗ = (R)-Benphos, (R)-Cyphos, (2R,4R)-Norphos] catalyse the 1,3-dipolar cycloaddition reaction of nitrones with methacrylonitrile with perfect regioselectivity, low-to-perfect endo-selectivity and low-to-mode...
Recombinant ethanolamine ammonia-lyase from S. typhimurium has been overexpressed and purified in large quantities by a simple procedure. The molecular weight of the native enzyme is about 480 kDa, and it contains two active sites/molecule as shown by kinetic studies and by titration with CNCbl....
Few studies have compared consumer sensory product attribute profiles and their influence on liking of regular and sodium-reduced foods. This study compared sensory profiles and overall liking between regular and sodium-reduced foods and examined the influence of consumption frequency of dietary...
In this study, we report a simple, non-degrading and efficient homogeneous acylation of cellulose diacetate (CDA) by using a large panel of commercially available acylating aliphatic moieties, differing in their structure (fatty, ramified, bulky, cycloaliphatic, aromatic, more or less spaced fro...
Viability of Listeria monocytogenes was monitored on frankfurters formulated with or without potassium lactate and sodium diacetate at a ratio of ca. 7:1 and treated with lauric arginate (LAE; 22 or 44 ppm) using the Sprayed Lethality in Container (SLIC®) delivery method. Without antimicrobials,...
We present the first reported study of imino-diacetate ion exchange resins which have been exchanged with aluminium ions which may offer an improved means of selectively removing fluoride ions from solution. Fluoride in water resources remains a significant problem worldwide often preventing or ...
As new pathogen intervention products come to market, it is important to ensure that they maintain or improve meat quality. Shelf-life and palatability traits were measured for top sirloins enhanced to 110% with solutions containing 0.5% sodium chloride and 0.4% sodium tripolyphosphate (CNT); CN...
Frankfurter-type sausages were prepared with potassium lactate, sodium diacetate and various levels of a mixture of potassium lactate and sodium diacetate. The development of Lactobacillus sake and Listeria monocytogenes and the sensory quality were compared with a reference product without any ...
The effects and interactions of temperature (56.3–60 °C), sodium lactate (SL; 0–4.8%), sodium diacetate (SD; 0–0.25%) and pediocin (0–10,000 AU) on Listeria monocytogenes on bologna were studied and a predictive inactivation model was developed. Bologna was manufactured with different SL/SD...
The effects and interactions of temperature (56.3–60 °C), sodium lactate (SL; 0–4.8%), sodium diacetate (SDA; 0–2.5%), and pediocin (0–10,000 AU) on starved Listeria monocytogenes (107 CFU/g) on bologna were investigated. Bologna slices containing SL and SDA in the formulation were dipped i...
This study reports the gene expression and filamentation in Listeria monocytogenes 08-5923 following exposure to food preservatives sodium lactate (NaL) and sodium diacetate (SD). L. monocytogenes 08-5923 was challenged with a mixture of NaL/SD, NaL or sodium acetate at 37 °C in tryptic soy bro...
Cytotoxicity and genotoxicity of sodium acetate (SA), sodium diacetate (SDA), and potassium sorbate (PS) was tested on Human Umbilical Vein Endothelial Cells (HUVEC). Cytotoxicity was investigated by MTT assay and flow cytometry analysis, while genotoxicity was evaluated using DNA fragmentation ...
An ICPC with high structure recoverability and paste stability was successfully developed directly incorporating PEG-6000 into the liquid phase of CPC. The rheological behavior of ICPC was investigated with rheometric scientific ARES902-30004 controlled strain rheometer. Novel approaches of flow...
In mammals a complicated homeostatic mechanism has evolved to maintain near consistency of extracellular calcium ion levels. The homeostatic mechanism involves several hormones, which comprise among others, parathyroid hormone and vitamin D. The recent resurge in vitamin D deficiency, as a globa...
β-Tricalcium phosphate (β-TCP) scaffolds with designed, three-dimensional (3-D) geometry and mesoscale porosity have been fabricated by direct-write assembly (robocasting) techniques. Concentrated β-TCP inks with suitable viscoelastic properties were developed to enable the fabrication of the...
Calcium carbonate is a chemical compound with the formula CaCO3 formed by three main elements: carbon, oxygen, and calcium. It is a common substance found in rocks in all parts of the world (most notably as limestone), and is the main component of shells of marine organisms, snails, coal balls, ...
Dicalcium phosphate cements were developed two decades ago and ever since there has been a substantial growth in research into improving their properties in order to satisfy the requirements needed for several clinical applications. The present paper presents an overview of the rapidly expanding...
ObjectiveTo determine phosphate concentration and pH in artificial tear eye drops commercially available in Spain.
The effects of phosphorylated chitin (P-chitin) on the tissue responses to two kinds of calcium phosphate cements (CPCs) were investigated using experimental rabbits. One of them consisting of monocalcium phosphate monohydrate, calcium oxide, 1 m phosphate buffer (pH: 7.4) and different amounts ...
