Flavor quality is of major importance to the consumer, but the flavor characteristics of beer appear to deteriorate greatly with time, at a rate depending on the composition of the beer and its storage conditions (notably pH). Prior to identifying the influence of pH on the development of the most intense staling flavors found in aged lager beers, the corresponding key flavor compounds were det...

The synthesis of a maltol-derived hydrazide is described which, once attached to a cell surface, induces rapid multicellular aggregation selectively in the presence of Fe(3+) ions. Heterocellular aggregates are also reported.

INTRODUCTION Sweeteners in tobacco products may influence use initiation and reinforcement, with special appeal to adolescents. Recent analytical studies of smokeless tobacco products (snuff, snus, dissolvables) detected flavorants identical to those added to confectionary products such as hard candy and chewing gum. However, these studies did not determine the levels of sweeteners. The objecti...

earth’s crust and has been implicated as an etiologic factor in neurological disorders including Alzheimer’s disease, Parkinson’s dementia syndrome, and dialysis encephalopathy syndrome. In fact, some evidence supports the selective accumulation of Al within neurons containing neurofibrillay tangles in patients with Alzheimer’s disease and within the aging human brain. Meiri et al., have also r...

Cocrystal engineering can alter the physicochemical properties of a drug and generate superior candidate for formulation design. Oxyresveratrol (ORV) exhibits poor solubility in aqueous environments, thereby resulting bioavailability. Extensive cocrystal screening ORV with 67 formers (coformers) bearing various functional groups was therefore conducted using grinding, liquid-assisted solvent ev...

As part of a study to characterize the detailed coordination behavior of Pu(IV), single crystal X-ray diffraction structures have been determined for Pu(IV) and Ce(IV) complexes with the naturallyoccurring ligand maltol (3-hydroxy-2-methyl-pyran-4-one) and its derivative bromomaltol (5-bromo-3-hydroxy-2-methyl-pyran-4-one). Although Ce(IV) is generally accepted as a structural analog for Pu(IV)...

Diabetic nephropathy is one of the serious complications in patients with either type 1 or 2 diabetes mellitus but current treatments remain unsatisfactory. Results of clinical research studies demonstrate that Panax ginseng can help adjust blood pressure and reduce blood sugar and may be advantageous in the treatment of tuberculosis and kidney damage in people with diabetes. The heat-processin...

Core-shell microcapsules with combined features of hydrophilicity and hydrophobicity have become much popular. However, the assembly biocompatible edible materials in hydrophilic-hydrophobic core-shell is not easy. In this work, based on electrostatic interactions, we prepared controllable calcium alginate (ALG)-zein particles different shapes sizes using hydrophilic ALG hydrophobic zein by a t...
