Patent number: 10437909Abstract: A food safety management tool that utilizes a mathematical model based on differential equations that is generalized for describing the continuous growth-death kinetics of microbial populations in foodstuffs. The method is used to provide a way to control target microorganisms when designing product formulations of minimally processed foodstuffs or when processing foods with high pressures, temperatures, or other lethal agents to achieve effective pasteurization, disinfection, or sterilization of foodstuffs, and includes the use of model parameters to predict food formulations to inhibit the growth of microorganisms and the processing times needed to reduce microbial hazards to levels that ensure consumer safety.Type: GrantFiled: September 1, 2009Date of Patent: October 8, 2019Assignee: Brandeis UniversityInventors: Christopher J Doona, Edward W Ross, Florence E Feeherry, Kenneth Kustin

Patent number: 8366961Abstract: This invention comprises a lightweight, portable chemical combination of reagents for sterilizing or disinfecting objects in the absence of electrical power or fire. The chemical combination includes a chemical oxidant with the capacity to liberate a biocidal intermediate, a chemical reductant of the oxidant with the capacity to react with the oxidant, and an effector to induce a reaction between the oxidant and reductant. In one embodiment, the oxidant comprises chlorite, the reductant comprises sulfite, and the effector comprises ascorbate. In another embodiment, the chemical combination comprises the oxidant, reductant, effector and iron-activated magnesium. When water or water solutions are added to either embodiment, the chemical combination generates heat, steam and a biocidal intermediate that can destroy contaminating microorganisms. In one embodiment, the biocidal intermediate is a halogen-based biocidal intermediate, such as chlorine dioxide.Type: GrantFiled: December 23, 2010Date of Patent: February 5, 2013Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Christopher J.

Patent number: 8337717Abstract: The present invention provides for a method of generating an aqueous solution comprising chlorine dioxide using a chlorine-containing chemical oxidant; an effector having the capacity to reduce said chlorine-containing chemical oxidant; a chemical reductant; and water, and operating in either batch or continuous-flow modes. In batch mode, the aqueous chlorine dioxide solution can be generated in a sprayer device, a bottle, or a bucket to disinfect objects by spraying and wiping, by pouring, or by immersion, respectively. In continuous-flow mode, the aqueous chlorine dioxide solution can be generated in flow tubes or continuous-stirred tank reactors, then placed inside a suitable sprayer device, bottle, or bucket.Type: GrantFiled: January 8, 2008Date of Patent: December 25, 2012Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Christopher J.
