Abstract
The idea of turning ‘‘waste to wealth” by means of industrial food residues can considerably contribute to sustainable development. The by-products of olive oil industry are an extraordinary source of bioactive phenolic compounds that are receiving great interest due to their antimicrobial and antioxidant activity, strongly related to cancer prevention, inflammatory disorders and cardiovascular diseases. One of the key principle in Green Chemistry is to substitute or minimize the use of hazardous solvents. In the last decade, a new generation of green solvents to be used both in synthetic transformations and in extraction processes has been developed. Deep eutectic solvents (DESs) are solvents with excellent properties such as negligible volatility at room temperature, that are water miscible, non-flammable, and highly viscous. They have attracted increasing attention in chemistry for the extraction and separation of target bioactive compounds from various natural samples. In continuation of our interest towards development of useful green methodologies,in this study we report a novel and sustainable approach for the extraction and derivatization of phenolic compounds from olive oil industry by-products (Figure 1) using deep eutectic solvents under microwave assistance. This procedure offers an efficient, safe, sustainable, and cost effective alternative to conventional methods for extraction and derivatization of bioactive compounds from olive oil industry by-products.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
