The use of encapsulated substances has been present in the industry since almost five decades, and is widely used in the pharmaceutical industry for time-release drugs and flavor masking [1]. In this process, the entrapped material –the carrier-, usually a liquid but also solids and gases, can be protected from heat and moisture by the… Continue reading Food industry applications of spray coating

Ultrasonic spray coating

Spray coating techniques are used to obtain thin films by the formation of fine droplets of the coating solution that are deposited on the substrate. In spray coating devices, pressurized air is used to atomize the liquid flow coming from the syringe into small droplets. These droplets are then deposited on the substrate, where they… Continue reading Ultrasonic spray coating
