Potato tubers of Group Phureja have a great relevance in terms of production and consumer acceptance in the Andean countries. However, its proximal characteristics, nutritional value and bioactive compounds have been scarcely known. For the first time, this work aims to give an overview on tubers of Group Phureja characteristics, including research works from 1993 to 2019. When analysing the micronutrients and bioactive analytes, sodium, niacin and carotenoid contents are higher as compared to those of the Group Tuberosum. Likewise, the application of a biorefinery approach for the valorisation of Group Phureja wastes was proposed. These wastes may come from tubers that fail to meet quality parameters or by processing potato products. The possibility of obtaining useful compounds for the food, feed, materials, energy and chemical industries is described. The strategy of valorisation of wastes was focused on the production of starch and proteins, previously reported with important technological properties.
