Electrostatic Coating of Dairy Products: A Modern Tool for Food Quality and Shelf-Life Enhancement

Abstract

Dairy products such as cheese, paneer, milk powders, and dairy-based snacks are highly sensitive to environmental conditions during processing and storage. The loss of coating materials, uneven distribution of flavours or protective agents, dust generation, and limited shelf life are common challenges faced by the dairy industry. To address these issues, modern food processing is increasingly adopting innovative technologies that improve efficiency while reducing waste. One of the promising emerging technologies for the coating of food products is electrostatic coating. The electrostatic coating is originally developed for industrial applications like painting and material finishing, but nowadays it has recently gained attention in food processing, including dairy applications. This techno
