N2 - Protein content, amino acid composition, nutritional quality and patatin characteristics were determined in tubers of four South American cultivated potato species (Solanum andigenum, Solanum goniocalyx, Solanum phureja, Solanum stenotomum) and a cultivar of the commonly cultivated cultivar Desiree of Solanum tuberosum. Protein content (on dry matter basis) of S. andigenum and S. stenotomum was highest at 7.9% and 8.0%, respectively, and the relative quantities of patatin for both species were 41.7% and 34.0%, respectively. The nutritional value of patatin, in terms of essential amino acid index with respect to a reference protein of FAO/WHO (EAAI(adult)) ranged from 93.0% (S. phureja) to 112.5% (S. goniocalyx). In case S. goniocalyx, the patatin fraction was a nutritionally better protein fraction than a protein concentrate or tuber dry matter, which had EAAI(adult) values of 97.6% and 82.9%, respectively. This suggests that this species may have potential in potato breeding programmes and in human nutrition.
