Background and Objectives: Cold plasma is used as an innovative solution in production and distribution of healthy and high-quality foods. Objectives of this study were to use cold plasma technology as a method for the structural modification of corn starch and its functional assessment in food models.  Materials & Methods: Starch granules were treated with plasma with two various gases in the ...

Mycotoxins such as Citrinin are small toxic molecules produced by a great variety of microorganism, which encompass several classes of secondary metabolites with no common chemical structure or mode of action. Citrinin produces by different species of Penicillium. Today, the cold atmospheric pressure plasma (CAPP) method has a potential for mycotoxin detoxification. In this study, a new and pro...

In this work, we investigated generating argon cold plasma jet at atmospheric pressure based on dielectric barrier discharge configuration using three electrical power supplies of sinusoidal, pulsed and saw tooth high voltage shapes at 8 KHZ. At first; we describe the electronic circuit features for generating high voltage (HV) wave forms including saw tooth, sinusoidal and pulsed forms. Then, ...

In this study we designed an RF plasma circuit. By using argon as plasma-forming gas, we investigated argon cold plasma plume at atmospheric pressure. Due to the tendency of transferring into arc mode after gas breakdown, resulting from the avalanche of electrons, we employed a glass tube as a dielectric barrier layer to inhibit the occurrence of the arc mode. We used an RF power supply at freq...

Cold Atmospheric Plasma is an ionized gas that has recently been extensively studied by researchers as a possible therapy in dentistry and oncology. Several different gases can be used to produce Cold Atmospheric Plasma such as Helium, Argon, Nitrogen, Heliox, and air. There are many methods of production by which cold atmospheric plasma is created. Each unique method can be used in different b...
