Abstract
AbstractExperimental conditions were worked out on a laboratory scale for the removal of alkaloids from seeds of bitter Peruvian lupin, Lupinus mutabilis. Four trials were carried out in this study using dilute aqueous solutions of HC1 and AcOH, and water. A simple und quick procedure is recommended for the removal of alkaloids from the whole seeds. The seeds are first soaked in 0.1N AcOH for 2hr, then boiled in water for 0.5hr, and eventually extracted with water for 8hr following the Soxhlet principle. More than 95% of the alkaloids are extracted by this procedure without leading to environmental pollution. The debittered whole seeds have a bland taste and contain around 50% protein and 20% fat Following Soxhlet extraction, the alkaloids are easily obtained as a side product.
