___________________________________ April 4, 2002 National Organic Standards Board Technical Advisory Panel Review Page 1 of 1 Compiled by OMRI for the USDA National Organic Program Executive Summary Potassium sorbate was petitioned for use as a preservative for an unspecified seed film coating. The reviewers were unable to fully evaluate the petition since the specific polymer was not identifi...

Isotherms were developed at pH 6.9 for adsorption (ADS) and coprecipitation (CPT) of Cu by hydrous oxides of Fe (HFO) and Al (HAO) to study the role of sorbate/sorbent ratio in metal cation removal. For low sorbate/sorbent conditions, HFO had a higher Cu retention capacity than HAO regardless of contact methodology. For either oxide, CPT was consistently more effective than ADS in removing Cu f...

The potentialities of different vapour sorption methods are analized for the investigation of the microstructure of wood sorbents (wood, cellulose and lignin) as a particular case of biopolymers. There are two important distinctions in the sorption behaviour of biopolymers from traditional rigid sorbents, namely, the dependence of the characteristics of the porous structure on the thermodynamic...

OBJECTIVE To measure the influence of topical steroids and the preservative potassium sorbate on the ciliary beat frequency (CBF) of human nasal mucosa in vitro. DESIGN In vitro study of cultured ciliated cells of human nasal mucosa. METHODS Human nasal mucosa was removed endoscopically and cultured for 10 days. Cell cultures with ciliated cells grown on an object slide were exposed to benz...

there are various methods for the analysis of potassium sorbate and sodium benzoate in food products, but a rapid and reliable method for identification of these preservatives in doogh (an iranian traditional dairy drink) is a procedure, in which high performance liquid chromatography (hplc) utilized and followed by uv diode array detection of the two preservatives. the aim of this case study w...

The functional shape of a sorption isotherm is determined by underlying molecular interactions. However, doubts have been raised on whether the mechanism can be understood in principle from analyzing curves via range competing models. We shown recently that it possible to translate interactions rigorous statistical thermodynamics. aim this paper fill gap between thermodynamic theory and experim...

Agric. Sci., 15: 307-311 The aim of present work was to investigate the antimicrobial effects of sodium benzoate, sodium nitrite and potassium sorbate and their synergistic action (sodium nitrite + s...

The immobilization of potassium sorbate, potassium aspartate and sorbic acid in layered double hydroxide under solid condition was examined. By simply mixing two solids, immobilization of sorbate and aspartate in the interlayer space of nitrate-type layered double hydroxide, so called intercalation reaction, was achieved, and the uptakes, that is, the amount of immobilized salts and the interla...
