Sanitary food washing stage in food production

Methods and systems are described for providing improved food processing systems by treating wash water in a wash stage of the food processing system with a biocide. Sufficient biocide may be added to significantly reduce the levels of bacteria in the wash stage, which can prevent problems associated with bacteria in downstream processes.

Enhanced peroxygen stability in multi-dispense TAED-containing peroxygen solid
11731889 · 2023-08-22 · ·

Stabilized compositions employing a sequestrant system and a binding system for improving shelf stability and dispensing stability of a solid activated bleach composition are disclosed. The compositions contain a peroxygen source and a catalyst activator which require generation of a peroxycarboxylic acid or other active oxygen sanitizing agent at a point of use. Stabilized compositions employ a sequestrant system including a phosphonic acid and/or dipicolinic acid sequestrant and a binding system comprising an anionic surfactant for a solid formulation of a catalyst activator and peroxygen source to provide shelf stability and dispensing stability for a activated bleach composition. Methods of formulating and use are further disclosed.
