GERMINATION AND DEBITTERING LUPIN SEEDS REDUCE ALPHA-GALACTOSIDE AND INTESTINAL CARBOHYDRATE FERMENTATION IN HUMANS

Subjects submitted to untreated and processed test meals of Lupinus al bus and Lupinus angustifolius had decreases in breath-hydrogen concent rations (as maximum and cumulative changes), for processed samples com pared to untreated samples. Maximum changes (means) in breath-hydrogen decreased from 56.7 and 66.7 DELTAppm in untreated L. albus and L. an gustifolius, respectively, to 8.4 and 5.9 DELTAppm in debittered sampl es (p <0.001), and to 29.6 DELTAppm in germinated L albus (p<0.01). Re sults paralleled the decrease in alpha-galactoside contents of germina ted and debittered samples which showed over 90% reduction. Germinatio n and debittering were very effective but debittering was more efficie nt to decrease fermentation in the human colon.
