Cold Plasma System for Food Industry
Dielectric barrier discharge (DBD) is a new and creative method to produce non-thermal plasma and has been noticed in various branches of science and technology.
(DBD) is an electrical discharge between two electrodes where at least one of the electrodes is covered with dielectric.
Applying an alternating voltage to the electrodes leads to the creation of a non-thermal plasma at atmospheric pressure.
One of the applications of this technology is in the food and agriculture industries.
Two attractive applications of DBD plasma:
1) Disinfection of the surface of food: Plasma has a great effect in this area due to its unique characteristics. The ability to disinfect heat-sensitive products by producing cell-killing active species, maintaining the sensory properties of the product, and being compatible with the environment are among the advantages of this new technology.
2) Seed Germination: Cold plasma modifies molecules through increasing surface energy, bond breaking, depolymerization, change in hydrophilicity, which causes changes in swelling power, water absorption, enzyme sensitivity, solubility power, and change in composite properties. , structure, heat of molecules and increases the growth and germination of seeds.
