Safety of food and maintaining its quality is the main concern in any heating process. Fulfilling consumer demand and needs is the main concern for any food processing industry. It has been found that ohmic heating is considered to be the most common and green process in food processing industries [50]. Infrared heating is still evolving and widely applied in drying especially low moisture food. Radiofrequency heating is less widespread as compared to other novel thermal heating technologies. Microwave heating is the most flexible and explored technology worldwide. It has a broad range of applications in hybrid systems. Microwave has great capabilities in sterilization and pasteurization. Novel thermal technologies have great potential and applications in producing safe and quality products with great efficiencies. A few drawbacks attached with these technologies are high investment cost and less control over all variables, which may delay its industrial implementation but its technical solutions are continuously evolving and are underway. Novel thermal technologies have many advantages over their drawbacks such as providing quality value-added products, energy-efficient, and environmentally sound, which proves it’s promising and novel as compared to conventional technologies.
