Microbiocidal treatment of edible fruits and vegetables

摘要

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 Br2 and (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).

1. Method of controlling bacterial, yeast, and/or mold contamination of at least one fruit or vegetable, which method comprises applying to the fruit or vegetable an aqueous microbiocidal composition, said composition containing less than 100 ppm (wt/wt) of active bromine and having been formed from components comprising water and at least one microbiocidal component that is selected from:
III) a concentrated aqueous microbiocidal composition having an active bromine content of at least 50,000 ppm, which composition is formed from components comprising water and (i) bromine chloride or bromine chloride and bromine, with or without conjoint use of chlorine and (ii) overbased alkali metal salt of sulfamic acid and/or sulfamic acid, alkali metal base, and water, wherein the relative proportions of (i) and (ii) are such that the atom ratio of nitrogen to active bromine is greater than 0.93, and wherein the pH of the composition is greater than 7; and IV) a solid-state microbiocidal composition which is a dewatered concentrated aqueous antimicrobial composition of III).
