Applications of electrostatic spray technology in food preservation

Abstract

The expectations for high food quality and safety keep rising in modern societies, driving the continuous development of food preservation technologies. Recently, the advantages of electrostatic spray technology have been explored for various applications, including food preservation. In this review, we first introduce the basic mechanism and unique advantages of electrostatic spray technology (including small droplet size, high deposition, uniform coverage and reduced agent use). Afterwards, we summarize the current advances of using electrostatic spray technology in food preservation and its economic benefits. The drawbacks and future perspectives of this field are also discussed. Increasing numbers of studies have shown the advantages of electrostatic spray technology in food preservati
