Abstract
The food-processing industry generates large quantities of residues, which may represent sustainable and rich sources of bioactive compounds. The extraction of bioactives from industrial residues could be a good alternative for the valorization of this by-product with recognized biological actions. Conventional extraction methods consume large volumes of organic solvents, which are expensive, toxic, and hazardous. Traces of the extractants in the final product make it unsuitable for pharmaceutical or cosmetic uses. Several methods, considered “green” or “eco-friendly,” have been proposed because of the low contamination, nontoxic, and nonflammable characteristics of the techniques. This chapter reviews the use of bioactive-enriched extracts obtained by environmentally friendly processes with sufficient quality to be incorporated into nutraceutical, pharmaceutical, and cosmetic formulations, highlights the challenges regarding bioactive compounds’ chemical stability, and presents the more recent strategies to overcome the technological issues of extracted bioactive molecules. The new concepts for recovered bioactives application are discussed.
