Aqueous and gaseous plasma applications for the treatment of mung bean seeds

Abstract Sprouts are particularly prone to microbial contamination due to their high nutrient content and the warm temperatures and humid conditions needed for their production. Therefore, disinfection is a crucial step in food processing as a means of preventing the transmission of bacterial, paras...
