“…hydroxyl. The physical effect like turbulence is also produced after the liquid circulation [15] . Previously, different proteins such as keratin [11] , peanut milk protein [16] , and soy protein isolate [17] have been successfully degraded and/or hydrolyzed by the application of hydrodynamic cavitation under different set of optimized conditions.…”

“…The violent collapse of the cavitation bubbles results in the generation of localized hot spots endowed with extremely high-energy density [20,21], highly reactive free radicals, and turbulence, which can result in the intensification of various physical/chemical phenomena. These include wastewater remediation and enhancement of biogas generation [22][23][24], preparation of nanoemulsions, biodiesel synthesis, water disinfection, and nanoparticle synthesis [25], among others.…”

Waste orange peel represents a heavy burden for the orange juice industry, estimated in several million tons per year worldwide; nevertheless, this by-product is endowed with valuable bioactive compounds, such as pectin, polyphenols, and terpenes. The potential value of the waste orange peel has stimulated the search for extraction processes, alternative or complementary to landfilling or to the integral energy conversion. This study introduces controlled hydrodynamic cavitation as a new route to the integral valorization of this by-product, based on simple equipment, speed, effectiveness and efficiency, scalability, and compliance with green extraction principles. Waste orange peel, in batches of several kg, was processed in more than 100 L of water, without any other raw materials, in a device comprising a Venturi-shaped cavitation reactor. The extractions of pectin (with a remarkably low degree of esterification), polyphenols (flavanones and hydroxycinnamic acid derivatives), and terpenes (mainly d-limonene) were effective and efficient (high yields within a few min of process time). The biomethane generation potential of the process residues was determined. The achieved results proved the viability of the proposed route to the integral valorization of waste orange peel, though wide margins exist for further improvements.

“…The increase in kinetic energy at the constriction occurs at the expense of pressure, leading to the generation of microbubbles and nanobubbles, which subsequently collapse under pressure recovery downstream of the constriction [21]. The violent collapse of the cavitation bubbles results in the generation of localized hot spots endowed with extremely high-energy density [22,23], highly reactive free radicals and turbulence, which can result in the intensification of various physical/chemical phenomena, including wastewater remediation [24][25][26], preparation of nanoemulsions, biodiesel synthesis, water disinfection, and nanoparticle synthesis [27], and many others.…”
