Omogeneizzazione ad alta pressione

In recent years, the food industry has increasingly shifted towards reducing the use of additives, favoring physical treatments to enhance process sustainability. High-pressure homogenization (HPH) is a non-thermal technology with strong industrial potential, based on the application of intense shear forces, turbulence, and cavitation to reduce particle size and modify fluid structure. Depending on the operating pressure, HPH and ultra-high-pressure homogenization (UHPH) can significantly affect the physicochemical and functional properties of food systems. Process performance depends on valve design, operating parameters, and the number of processing stages. HPH influences multiple components, including proteins (structural modifications), lipids (size reduction and stability), and fibers (enhanced solubility), improving properties such as emulsification, viscosity, and stability. However, mechanical stress, equipment limitations, and energy costs must be carefully managed. Overall, HPH represents a promising strategy for developing minimally processed foods with improved functionality, reduced additive use, and enhanced product quality.
