✦ Synopsis


Detoxification of apricot kernels by soaking in distilled water and ammonium hydroxide for 30 h a t 47 "C decreased the total protein, non-protcin nitrogen, total ash, glucose, sucrose, minerals, non-essential amino acids, polar amino acids, acidic amino acids, aromatic amino acids, antinutritional factors, hydrocyanic acid, tannins and phytic acid. On the other hand, rcmoval of toxic and bitter compounds from apricot kernels increased the relative content of crude fibrc, starch, total essential amino acids. Higher in-vitro protein digestibility and biological value was also observed. Generally, the detoxified apricot kernels were nutritionally well balanced. Utilization and incorporation of detoxified apricot kernel Hours in food products is completely safe from the toxicity point of view.

Zusammenfassung

Biochemische Untersuchungen iiber einige nicht konventionelle Protcinqucllcn. 7. Mitt. EinfluB der Dctoxifizierung auf die nutritive Qualitiit von Aprikosen Die Detoxilizierung von Aprikosenkernen durch Einweichen in destillicrtem Wasscr und in Ammoniumhydroxid (30 h, 47 "C) fiihrte zu einer Abnahme des Gesamtproteins, des Nichtprotein-N, der Gesamtasche, Glucose, Saccharose, Mineralstoffe, essentiellen Aminosiiuren, polaren Aminosiuren, sauren Aminosauren, aromatischen AminosCuren, antinutritiven Faktoren, Blausiiure, Tannine und Phytinsaure. Andercrseits fiihrte die Entfcrnung dcr toxischen und. titteren Verbindungcn aus Aprikosenkeriien zu einer Erhohung des relativen Gehaltes an Rohfaser, StCrke und der gcsamten essentiellen Aminosiiuren. Es waren auch eine Verbesserung der in vitro-Verdaulichkeit der Proteine und der biologischen Wcrtigkeit festzustellen. Ganz allgcmein ist festzustcllcn, daB die detoxifizicrten Aprikosenkerne niihrwertmiiRig gut ausbalanciert sind. Die Verwertung von dctoxifizierten Aprikosenkernmehlen in Lebensmitteln ist aus toxikologischer Sicht vollig gefahrlos.
