About this Research Topic
Agro-produce wastes and by-products, particularly fruits and vegetable wastes, are high in beneficial compounds. These bioactive compounds have grown in popularity in recent years due to their wide range of applications in industries such as food, herbal, and cosmetics. These bioactive compounds are finding widespread use as nutraceuticals and functional foods. Peels, pomace, leaves, and seeds are potential feedstock for bioactive compounds like pigments, polyphenols, pectin, flavonoids, essential oils, polysaccharides, and so on. The beneficial and therapeutic properties of these bioactive compounds have prompted researchers to use novel extraction techniques to extract these highly valuable compounds from agro-waste. Therefore, it is necessary to utilize this bioactive rich waste (trash to treasure approach) by extracting them using greener and less hazardous techniques such as ultrasound assisted extraction, supercritical fluid extraction, pulsed electric field, hydrodynamic cavitation, etc. This green extracted bioactive waste then can be used in formulating functional and nutraceutical foods, besides their use as food additives and preservatives. They are currently used as colorant and flavoring agents in food as they are generally recognized as safe (GRAS).
That is why a compilation of all available advanced knowledge at a single point is critical for future issues and new advances. With this special issue, we would collect both new advances and old-age practices that may be appropriate in the present day.
