Microbial decontamination of particulate food using a pilot-scale atmospheric plasma jet treatment system
نویسندگان
چکیده
A pilot-scale treatment system of atmospheric plasma jet (APJ) was developed and its effects on the inactivation natural bacteria in rice germ, black pepper powder, sesame were investigated. The optimal sample amount, rotary valve speed, operation time, pressure for determined to be 200 g, 40 rpm, 10 min, 0.2 MPa, respectively, which inactivated by 1.4, 1.0, 1.4 log CFU/g, respectively. Dust removal pre-treatment increased microbial reduction level 2.2 CFU/g. Plasma did not alter color germ antioxidant activities powder sesame. consumed 1.6 times less energy than conventional heat treatment. results demonstrated potential using APJ disinfection particulate food.

Microbial Decontamination of Spices Using Cold Plasma
Most of spices are produced using traditional systems. In unsanitary conditions, spices can contain large numbers of pathogenic microbes such as bacteria, molds and yeasts. Some microorganisms are known as human pathogens, which need disinfection mechanisms that minimize their potential harms to active substances in spices. Use of contaminated spices in foods can significantly decrease the shel...
متن کاملSimulation of a Helium Atmospheric Plasma Jet Using Fluid Equations
In this study, a cold atmospheric He plasma jet is investigated. The jet is of dielectric barrier discharge type, consisting of a dielectric tube with two metal ring electrodes. The continuity, momentum and energy conservation equations as well as the Poisson equation for obtaining the potential and the electric field, accompanied with the ideal gas laws, are used for the simulation. The result...
متن کاملLow temperature atmospheric plasma for microbial decontamination
Low temperature Plasma (LTP) is a high-energy gas that is created when an electrical current is passed through a gas. Until recently, plasmas could only be created at relatively high temperatures in a vacuum and the use of plasma on sensitive materials such as human tissue, food products, medical devices and the packaging industry, was therefore impractical. However, over the last few years tec...

The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines No...
متن کاملMycotoxin Decontamination of Food: Cold Atmospheric Pressure Plasma versus “Classic” Decontamination
Mycotoxins are secondary metabolites produced by several filamentous fungi, which frequently contaminate our food, and can result in human diseases affecting vital systems such as the nervous and immune systems. They can also trigger various forms of cancer. Intensive food production is contributing to incorrect handling, transport and storage of the food, resulting in increased levels of mycot...
