Botanical Overview
Andean Lupine (Lupinus mutabilis) is a species in the Fabaceae family. The legume family (Fabaceae) includes trees, shrubs, and herbs that produce pods (legumes) and form nitrogen-fixing root nodules through symbiosis with bacteria. The flowers are typically pea-shaped with five petals. This large family provides food staples, timber, and numerous medicinal species. Although comprehensive ethnobotanical records are limited, phytochemical studies have identified 16 compounds in this species, suggesting potential medicinal value.
General Description
Vernacular names include tarwi (in Quechua II, pronounced tarhui), chocho, altramuz, Andean lupin, South American lupin, Peruvian field lupin, and pearl lupin. Its nutrient-rich seeds are high in protein, as well as a good source for cooking oil. However, their bitter taste has made L. mutabilis relatively unknown outside the Andes, though modern technology makes removing the bitter alkaloids easier. Like other species of lupin beans, it is expanding in use as a plant-based protein source.
