ABSTRACT
The coffee industry is an industry that generates a large amount of agroindustrial waste as it is the second-largest commodity in the world. The main residues of this commodity are coffee pulp, which represents 40–45% of the fruit’s dry weight, husk coffee, which represents 50% of the weight of the dry fruit, and the spend coffee grounds (SCG) represent 65% in weight of the roasted coffee. This last residue is obtained during the brewing process and generates around 6 million tons per year derived from the consumption of coffee. Its composition is rich in proteins, lipids, mainly fatty acids, cellulose, lignin, tannins, antioxidant compounds of the anthocyanin type, hydroxycinnamic acids, and monosaccharides, such as arabinose, galactose, and mannose. These compounds can be exploited as a source of biological compounds, thus decreasing the environmental pollution generated by these 150residues from the coffee industry. This chapter explores the composition of this residue and the main bio-products that can be obtained from this material using biotechnological strategies.
