Zeitschrift für Ernährungswissenschaft Aims and scope Submit manuscript

Summary

  1. 1.

    General analysis of the seeds for protein, fats, carbohydrates, fiber and ash contents were carried out and the results were given in g/100 g dry seeds.Lupinus termis contained a higher percentage of protein (40.36), 290 mg calcium and 6.5 mg iron.

  2. 2.

    All the essential amino acids are present in fair amounts with the exception of sulphur-amino acids and Lysine.

  3. 3.

    Cooking the seeds resulted in a slight decrease of most of the amino acids with the exception of Tryptophan and Lysine, which exhibited a slight increase after cooking.

  4. 4.

    Of the toxic substances present in the seeds is Trypsin inhibitor, which was destroyed by heat treatment, and alkaloids, which were removed by soaking the seeds three days in running tap water.

  5. 5.

    Supplementing the debittered seeds with Lysine and Methionine resulted in an increase in its nutritive value.

Zusammenfassung

  1. 1.

    Lupinensamen wurde auf seinen Gehalt an Proteinen, Fetten, Kohlenhydraten, Faser- und Aschestoffen analysiert. Die Ergebnisse wurden in g/100 g für trockenen Samen angegeben.Lupinus termis enthielt einen höheren Prozentsatz an Protein (40,36), 290 mg Calcium und 6,5 mg Eisen.

  2. 2.

    Alle essentiellen Aminosäuren mit Ausnahme von schwefelhaltigen Aminosäuren und Lysin sind in angemessener Höhe enthalten.

  3. 3.

    Das Kochen der Samen bewirkte eine leichte Verminderung der Aminosäuren mit Ausnahme von Tryptophan und Lysin, wo nach dem Kochen ein leichter Anstieg zu verzeichnen war.

  4. 4.

    An toxischen Stoffen sind in den Samen der Trypsin-Inhibitor, der bei Hitzebehandlung zerstört wird, und Alkaloide enthalten. Letztere wurden durch dreitägiges Einweichen der Samen unter laufendem Wasser eliminiert.

  5. 5.

    Der Nährwert der entbitterten Samen wurde durch Zusätze von Lysin und Methionin erhöht.
