Effect of the solid state fermentation of cocoa shell on the secondary metabolites, antioxidant activity, and fatty acids.

During cocoa ( L.) processing, the accumulated cocoa shell can be used for bioconversion to obtain valuable compounds. Here, we evaluate the effect of solid-state fermentation of cacao flour with on secondary metabolite composition, phenol, carotenoid, anthocyanin, flavonol, and fatty acids contents, and antioxidant activity.
