    Research Topic: Subcritical fluid technology for obtaining high-value compounds from coffee industry by-products.
    Currently, food industries are getting more and more interested in valorizing their by-products by novel methods. Subcritical fluid technology is a promising technology for this purpose. Subcritical water can be used to hydrolyze macromolecules such as polysaccharides, protein, and fat into higher value products such as mono-and oligo-saccharides, amino acids, and fatty acids while subcritical aqueous ethanol can be used to enhance both extraction of bioactive compounds and promote other reactions such as isomerization of sugars into their rare isomers. In this research, coffee by-products such as, coffee pulp, spent coffee ground will be targeted.
