Chemical, Functional, and Structural Properties of Spent Coffee Grounds and Coffee Silverskin

Spent coffee grounds (SCG) and coffee silverskin (CS) represent a great pollution hazard if discharged into the environment. Taking this fact into account, the purpose of this study was to evaluate the chemical composition, functional properties, and structural characteristics of these agroindustrial residues in order to identify the characteristics that allow their reutilization in industrial ...

Extraction of polysaccharides by autohydrolysis of spent coffee grounds and evaluation of their antioxidant activity.

The extraction of polysaccharides by autohydrolysis of spent coffee grounds (SCG) was studied. Experimental assays were performed using different temperatures (160-200°C), liquid/solid ratios (5-15ml water/g SCG) and extraction times (10-50min) in order to determine the conditions that maximize the extraction of polysaccharides with high antioxidant activity. Autohydrolysis was demonstrated to ...
