Handbook of Coffee Processing By-Products

Coffee is one of the most consumed beverages in the world. Due to the great demand of this product, large amounts of wastes are generated in the coffee industry. Coffee silverskin and spent coffee grounds are the main by-products obtained during coffee roasting and brewing processes. Coffee silverskin contains several bioactive compounds, including prebiotic carbohydrates, dietary fiber and antioxidants and has been proposed as a natural source of health promoters or functional food ingredients. Spent coffee grounds, coffee silverskin, and other coffee processing by-products are typically discharged into the environment or are treated in ways that diminish their beneficial properties. This practice impacts the sustainable and bioeconomical framework of the modern coffee processing industry. Handbook of Coffee Processing By-Products: Sustainable Applications presents alternative and sustainable solutions for these coffee processing by-products and specifies their industrial potential, both as a source for the recovery of bioactive compounds and their reutilization in the pharmaceutical, biotechnological, food, biotechnology, and cosmetic industries as well as in environmental and agronomic applications. This book addresses key topics specific to sustainable management in the coffee industry. Emphasis is placed on integrated solutions for the valorization and upgrade of coffee processing by-products, biorefinery, and different techniques for the separation, extraction, recovery, and formulation of polyphenols.
