“…To be sold in the domestic or foreign market for food purposes, coffees with similar classifications to those analyzed in this work need to go through the re-processing of the beans, carried out by densimetric separation and electronic sieve shaker, at the cost of U$ 2.00 per bag of 60 kg (Cafesul, 2021), however, this process is only carried out in export-type coffees, due to the high cost. If not, then they must be diluted in batches of better-quality coffees, which it will result in a product with low market value, but that meets the current legislation (de Almeida and Spers, 2020;Kalschne et al, 2018;Santos and Nantes, 2014;Toci and Farah, 2014).…”
