Experimental study on sterilization of food with self-igniting plasma formed from liquid using plasma-based ion implantation
Koji Kakugawa, Manami Hosotani, Miyo Arikado, Tomonori Tabe, Kenta Fukutomi, Yoshinobu Tsuchiya, Takeshi Tanaka

Cite as:

We attempted to sterilize food using plasma-based ion implantation with self-ignited plasma formed from liquid. Based on sterilization experiments, hydrogen peroxide was selected to generate self-ignited plasma. The most effective ...  read more

density distribution of plasma, density of oxygen ions, food sterilization, Pegasus simulations, Penning effect

Cite as:

We attempted to control the density of oxygen ions by adding argon gas and helium gas with metastable voltage to oxygen gas with ionization voltage, in order to determine the optimum combination and ratio of gases for food ...  read more
