Methods of controlling bacterial, yeast, and/or mold contamination of edible fruits or vegetables comprise applying thereto an aqueous microbiocidal composition formed from water and (A) at least one component selected from (I) a solid-state microbiocidal compound having at least one bromine atom per molecule; (II) an aqueous solution/slurry of a compound of (I); (III) a concentrated aqueous composition having an active bromine content of at least 50,000 ppm derived from water and (i) BrCl or BrCl and Brand (ii) overbased alkali metal sulfamate, where the relative proportions of (i) and (ii) give an atom ratio of nitrogen to active bromine greater than 0.93, and where the pH of the composition is greater than 7; and (IV) a solid-state composition formed by dewatering a composition of (III).

Microbiocidal treatment of edible fruits and vegetables

Disclosed are sorbents having superior water leachability performance characteristics especially when used as sorbents in semi-dry (CDS), high moisture (SDA), and fully wet SOscrubbers. Also disclosed are methods for the production of such performance-enhanced sorbents, and methods for the use of such sorbents in the removal of mercury and possibly one or more other heavy metals or other contaminants from various gaseous streams. The sorbents are carbonaceous substrates treated with a bromine-containing compound, especially gaseous bromine, and with at least one organic compound that contains at least one olefinic double bond.

Flue gas sorbents, methods for their manufacture, and their use in removal of mercury from gaseous streams

Ultraviolet light stabilized antimicrobial compositions are formed from (A) and (B). (A) is (I) a solid-state microbiocidal compound having at least one bromine atom in the molecule; (II) an aqueous solution or slurry of (I); (III) is a concentrated aqueous antimicrobial composition having a dissolved active bromine content derived from (i) BrCl or BrCl and Br2 and (ii) overbased alkali metal sulfamate and/or sulfamic acid, alkali metal base, and water, (IV) solids made by dewatering a composition of (III). (B) is a ultraviolet light degradation-inhibiting amount of up to one part by weight of ascorbic acid, dehydroascorbic acid and/or an edible water-soluble salt/ester thereof per part by weight of bromine in the selected antimicrobial composition. Preparation and uses of such compositions are described. Methods of controlling contamination of seafood and seafood products by pathogens are also described.
