Colombia is the third largest coffee producer in the world and is recognized for its superior quality product. Nariño, it is the most representative agricultural activity but with low sophistication in the transformation processes. The objective of this study was to develop a coffee of Nariño origin that possesses the acceptability and functionality of Ganoderma lucidum. The total polyphenol content was determined using the Folin-Ciocalteu method, antioxidant activity using the DPPH method, and evaluation of structural functional groups using Fourier-transform infrared spectroscopy (FTIR) for the fruiting body and mycelial biomass of G. lucidum. The total polyphenol content and antioxidant activity were higher in the mycelial biomass (41,67 ± 4,35 mg EAG/g and 6,49 ± 0,99 µmol Eq Trolox/g extract) compared to the fruiting body (14,31 ± 1,85 mg EAG/g and 4,80 ± 0,25 µmol Eq Trolox/g extract). The IR spectra of the fruiting body and mycelial biomass showed similarity in both spectra, among the peaks, broad and strong bands, indicating that their chemical composition is similar, but not in concentration. In the development of coffee, mycelial biomass of G. lucidum was added in three concentrations (6, 8 and 10 %), and the sensory profile of the cup was evaluated following some of the cupping protocols of the SCAA (Specialty Coffee Association of America). The results of the sensory analysis for the samples with 8 and 10 % mycelial biomass in coffee showed an increase in their scores, reaching nearly the scores of the control sample, and these scores remained relatively constant at 8 and 9 points, placing the enriched coffee within the SCAA range as an excellent and extraordinary coffee, respectively. This demonstrates a promising method for the direct application of mycelial biomass in food for the development of functional foods. [ABSTRACT FROM AUTHOR]

The specialty coffees of the Department of Nariño have been recognized worldwide for their excellent quality, but they have been affected by the inadequate handling of the product in its supply chain, specifically in the areas where it is stored, directly affecting its differential attributes, therefore which presents an approach to solve the problem of selection and location of possible potential areas, for the establishment of a distribution center, essential for its entire chain. In the present study, a decision-making approach with multiple criteria (MCDA) was applied, specifically the analytical hierarchy process (AHP) and weighted linear combination (WLC), with the incorporation of geographical criteria and their implementation in GIS (Geographical Information Systems), where 38 possible alternatives (Producing Municipalities) were evaluated for the establishment of a distribution center, using criteria previously identified with the help of experts in the areas of location, logistics, connectivity and specialty coffees, where those selected were: production Municipal, road connectivity and average temperatures. As results, maps of normalized and weighted criteria were generated according to the qualification or level of importance given by the experts through the model (AHP) and later using the weighted linear combination method (WLC) and GIS, the possible ideal areas were identified for the establishment of the distribution center. In conclusion, we can affirm that as the number of criteria increases, it implies greater complexity for decision-making, being of great help the implementation of technological tools such as GIS for the analysis and management of information in the resolution of this type of problems, which in the specific case of this project brought us closer to having a departmental overview of the possible ideal areas to establish a distribution center for specialty coffees. In detail, the methods and criteria used, data sets used, results obtained and discussion, finally the most significant conclusions, are described. [ABSTRACT FROM AUTHOR]
