Recent advances in extraction technologies of phytochemicals applied for the revaluation of agri-food by-products

摘要: Agri-food by-products, i.e., seeds, peels, roots, leaves, and stems are produced during fruits and vegetables processing. These by-products still represent a disposal problem for the food industry. Thus, alternative uses for agri-food by-products are being explored. In this context, an increasing number of research studies have demonstrated that they are a good source of phytochemicals, e.g., carotenoids, phytosterols, flavonoids, or anthocyanins with high bioactivity against several common diseases such as hypertension, diabetes, or dyslipidemia. In this regard, to revalue agri-food by-products, the extraction, which involves the separation of phytochemicals from inactive components, is an important step necessary for the recovery of the desired phytochemicals from agri-food by-products. Thus, this chapter includes the state of the art of different extraction technologies such as conventional extraction, ultrasound …
