AMURRIO D., David. Of products and patents: the case of yacon. RevActaNova. [online]. 2023, vol.11, n.1, pp.76-87.  Epub Mar 31, 2023. ISSN 1683-0789.  https://doi.org/10.35319/acta-nova.202314.

Yacon (Smallanthus sonchifollius (Poepp.) H. Rob), a little-known tubber was studied for fructan extraction (87.7%), ethanolic fermentation (5.5-6.5% (vol.)), acetic fermentation (pH=3.21-3.82), foam-mat drying (constant rate 4 times faster, final humidity 7 times lower in half the time when compared to the non-foamed product), as well as texturizing agent in dairy products. We uncovered over 3000 foreign patents that represent barriers for the industrialization of yacon. A content- based analysis of the patent is presented. 83.02% of the patents belong to China, Korea, Japan and Rusia. In almost 17% of the cases, yacon is the direct object of the patent. 59% of the patents are related to foods.

Keywords : Yacon; Smallanthus sonchifolius; industrial products; patents.
