Ultra-high-temperature ohmic heating of fruit pulps

[Excerpt] Ohmic heating (OH) is an environmentally-friendly innovation in food processing, generating heat internalty through electrical resistance. lt eliminates the need for boilers, reducing water and energy consumption, while its high efficiency minimizes waste and supports renewable energy integration. By avoiding stirring, scraping, and high thermal loads, OH reduces fouling, preserves product quality, and offers an eco-friendly, efficient solution for the food industry [1]. A significant knowledge gap exists regarding the feasibility and impact of ohmic heating at ultra-high temperatures, particularly in its application for the sterilization of food products.
