Coffee is the most traded agricultural commodity in the world. Currently, Peru is considered the third principal producer of Coffea arabica in South America, and the sixth worldwide, accounting for 6 % of the global production. However, most of the coffee (~ 99 %) is exported as green beans due, in part, to the fact that the local quality control of the roasting process is not yet optimal. Hence, it is crucial to develop a more standardized process for the quality control of roasted coffee beans that will allow local Peruvian coffee farmers to introduce to the market a more valuable product. In the thesis presented here, work associated with the project FINCyT-PIPEI-PUCPCENFROCAFE- 2012 on the quantitation of the main compounds developed during the roasting process was embraced using NMR and HPLC-DAD methodologies. Attention was focused on the secondary metabolites that, from a flavor-ar...

This article delves into the problem of contradiction in Nietzschean philosophy, taking Müller-Lauter’s interpretation as the main reference. Its main objective is to shed light on the path followed by Nietzsche towards the postulation of the will to power as a perspectivist reading of reality, which replaces the traditional notion of metaphysical truth. The argument focuses on refuting the equalization of Nietzschean perspectivism with the arbitrariness of a crude relativism, by examining the relationship between the will to power and the will to truth.
