Abstract

The search for new technologies and ingredients with interesting characteristics and potential for incorporation into functional foods emerges in parallel with the demand for alternative sustainable and economically viable blends. Pursuing these aims, the formulation of a new coffee blend with 94% roasted coffee powder (Coffea canephora cv. Robusta and Coffea arabica, 70/30, w/w), 3% cocoa powder, 2% coffee silverskin and 1% golden coffee (green coffee minimally processed) was developed. The influence of the ingredients in the blend was compared with two other commercial coffee blends (in capsule and in a sealed package with a one-way degassing valve), being characterized the formulation, the physicochemical parameters, as its innovation. It is concluded that the developed coffee blend shows an enriched content of bioactive compounds (chlorogenic acids, trigonelline, theobromine and caffeine), displays an important antioxidant capacity and was favorably appreciated due to its sensory characteristics. Moreover, the addition of skin by-product becomes an additional valorization and the processing of green coffee and cocoa was minimized by adding innovation and an optimized extraction.
