Abstract :

Plasma technology is one of the new technologies that has found many applications in various industries, including the food industry. Plasma is actually called the fourth state of matter, which is used in sterilization of medical supplies and equipment, equipment used in food industry and food processing. Cold plasma is a dry, non-thermal technology without the need for chemicals, which is able to work continuously at atmospheric pressure, and due to its non-thermal nature, it can be a suitable alternative to other chemical and physical methods used for sterilization and Pasteurization of food. Plasma sterilization techniques are effective, simple and fast (from a few seconds to an hour) and have a lower temperature (less than 70 degrees). The research done in relation to cold plasma has shown that it has the ability to kill microbes and can also destroy vegetative forms, spores and fungi. Also, these studies show that the type of food product, the source of plasma production, the state of exposure of the plasma (direct or indirect) to the desired substance are vital in controlling the effects of cold plasma on antioxidant activity, nutritional value and organoleptic characteristics of food products. Therefore, getting acquainted with this method in order to use plasma technology in the food industry can be an important step in the advancement of science and food industry.
