Potassium Sorbate
___________________________________ 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...
متن کاملPotential for Development of Tolerance by Penicillium digitatum and Penicillium italicum after Repeated Exposure to Potassium Sorbate.
Two strains of Penicillium digitatum and one strain of Penicillium italicum were exposed to various levels of sorbic acid and potassium sorbate, and the MICs were determined. Selected strains of the molds were then repeatedly exposed to subinhibitory levels of the compounds to determine whether increased tolerance might develop. The MIC of sorbic acid (pH 4.75) to P. digitatum was between 0.02 ...
متن کاملAlkylating potential of potassium sorbate.
A kinetic study of the alkylating potential of potassium sorbate (S)-a food preservative used worldwide-in 7:3 water/dioxane medium was performed. The following conclusions were drawn: (i) Potassium sorbate shows alkylating activity on the nucleophile 4-(p-nitrobenzyl)pyridine (NBP), a trap for alkylating agents with nucleophilic characteristics similar to those of DNA bases, (ii) The NBP alkyl...
متن کاملThe Antifungal Effect of Potassium Sorbate on Penicillium sp in Labaneh
This study investigated the antifungal effect of polyethylene films coated with potassium sorbate on Penicillium sp. At beginning, we used different concentrations of potassium sorbate in coating the polyethylene films to determine the most effective concentration against Penicillium sp. The concentrations used were (0.0, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.5, 5.0, 5.5 and 6.0%) and 2.5% was the mi...
متن کاملIdentification of some secondary metabolites produced by four Penicillium species
Fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. The present study was aimed to identify secondary metabolites from some Penicillium species, using GC-MS. Many important compounds such as 3-oxoquinuclidine in Penicillium jenseii, formamidine in Penicillium pusillum, orcinol and 1,3,8-p-mentha...
