Methods for Extraction of Bioactive Compounds from Products: A Review

Abstract

Most agricultural by-products are not recycled or fully utilized. Most of them end up in waste and cause economic, social and environmental problems. Today, much of the byproducts are considered waste, although they can be appropriately recycled to produce new value-added products. By-products have great potential to create, for example, food additives. Many of these byproducts are a source of valuable compounds such as proteins, lipids, starches, trace elements, bioactive compounds and dietary fiber. A wide variety of extraction methods are currently available, but several factors must be considered to determine which of these methods can efficiently and environmentally produce high-value-added products from by-products. The article examines, summarizes and compares various extraction methods, as well as products that are currently obtained using specific methods.
