Cold plasma in food processing and preservation: A review

Abstract

Abstract The need for safe and healthy foods has increased since the turn of the century. Novel non‐thermal food processing technologies are being adopted by the food sector. Cold plasma (CP) is a proposed, non‐thermal food processing method that inactivates contaminating bacteria on foods and packing materials by using charged, highly reactive gaseous molecules and species. It was originally established to improve the printing and adhesive capabilities of polymers, as well as several electronic applications. The uses of cold plasma have expanded up to food industries in recent decades as a powerful tool for non‐thermal food processing, with a variety of applications. The impact of CP on food quality is crucial to its acceptability as an alternative food processing technology. As the cold
