New insight into coffee by-products

Coffee is one of the most popular beverages, and the worldwide production is over 105 million tons annually. Industrial processing of coffee fruit is done to isolate coffee powder by removing shell and mucilaginous part from cherries. Coffee is subjected to two methods of processing (dry and wet) such as pulping, washing, drying, curing, roasting, and brewing, and during the process, various by-products such as coffee pulp , cherry husk , parchment husk , silver skin , and spent waste are obtained . Clearance of these materials usually represent environmental problem. The cost of drying, storage, and transport poses additional economical margins to waste utilization and is often utilized as feed or fertilizer. Thus, new aspects concerning the use of these by-products for further exploitation as food additives or supplements with high nutritional value have gained increasing interest because these are high-value products and their recovery may be economically attractive
