This picture is a device that produce plasma in atmospheric condition.
This pictures are a variety application of atmospheric plasma treatment.
I will show the short movie of atmospheric plasma devices.
Applications of atmospheric plasma
There are a variety of the applications of atmospheric plasma treatment.
Among these applications , we focus on the sterilization.
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
