Green and Clean Extraction Technologies for Novel Nutraceuticals

Phytochemicals extracted from leaves, fruits, roots, and seeds of plants exhibit high nutraceutical, antioxidant, and antimicrobial potential. Such valuable components can be obtained from natural materials via extraction, an important parameter in analytical chemistry. Since conventional extractions methods pose severe environmental threats and have a negative impact on energy economy, moving toward green strategies is important. Green technologies are ecofriendly and give maximum yield, and the product obtained are pure and less toxic. Ultrasound, microwave, supercritical fluid, subcritical fluid, pressurized liquid, enzymatic hydrolysis, radio frequency, electroosmotic dewatering, cold plasma treatment, high-pressure processing, electrotechnology, ionic liquid, accelerated solvent extraction, and hydrotropic extraction are some of the methods used in clean and green technologies to extract biologically active components from plants. This chapter also discusses nonthermal extraction technologies . This chapter on clean and green technologies, processes, and protocols will provide collective and advanced knowledge to research community in the food and nutraceutical sectors.
