The aim of this study was to remove the alkaloids from bitter lupin (Lupinus albus L.) seeds by different debittering methods and to produce a lupin bean snack. During production of the snack, the total alkaloid content of seeds decreased significantly (P < 0.01) from 14.4 g/kg to a level that was undetectable. A major alkaloid in lupin seeds was identified as lupanine. It was present at a concentration of 12.513 g/kg, which constituted 87% of the total alkaloid content. The other alkaloids that were identified were sparteine, albine, alpha-isolupanine and multiflorine. The concentrations of the alkaloids decreased gradually during the debittering process. The values for dry matter, protein, lipid, starch and ash content of seeds changed in a statistically significant manner (P < 0.05, P < 0.01) during production of the snack. Aqueous debittering at room temperature was found to be a more favorable process because it resulted in more acceptable sensorial properties than alkaline and thermal debittering methods.
