    Notes: The use of resonance Raman spectroscopy in the determination of food dyes was studied with the yellow, orange and red dyes registrated by the European Economical Community. The natural dyes studied did not exhibit a resonance Raman spectrum, but most of the artificial dyes give spectra that can be used for analytical determinations. The detection and identification limits are sufficiently low for practical use. The identification capability and its advantage over absorption spectrometric measurements are demonstrated on a commercial bubble gum sample. Quantitative measurements indicated a good accuracy for this method.

    Description / Table of Contents: Zusammenfassung Seit 1931 ist bekannt, daß Mangan ein essentielles Spurenelement bei Tieren ist. Heute weiß man, daß Manganmangel bei Tieren zu einer Vielfalt an Stoffwechseldefekten führt. Für den Menschen ist die sichere Versorgung durch die enterale Ernährung mit 2,5–5 mg pro Tag gewährleistet, für die parenterale Ernährung wird eine Dosis von 0,15–0,8 mg pro Tag vorgeschlagen. Die Mangangehalte von Bestandteilen der Nahrung und von Infusionslösungen wurden durch Atomabsorptions-Spektrometrie bestimmt. Die Ergebnisse wurden mit den (aus Tabellen) kalkulierten Werten verglichen. Der Mangangehalt der Kleinkomponenten und Zusatzstoffe einschließlich der Aromastoffe wurde ebenfalls berücksichtigt. Aus dem täglichen Gesamtverzehr wurde eine Manganaufnahme von 192–7373 µg berechnet. In der parenterelen Ernährung betrug die Manganmenge der Lösung vor Zugabe einer Supplementmischung (Oligo-Komplex) 0,2% der Gesamtdosis an Mangan. Nach Zugabe der Oligo-Komplex-Mischung wurde eine tägliche Aufnahme von 5,02±0,16 pro Tag festgestellt.
    Notes: Summary Managanese has been proven to be an essential trace element in animals since 1931. Today, it is known that manganese deficiency results in a wide variety of structural and physiological defects in animals. For humans, the safe and adequate range of intakes for manganese by enteral nutrition is 2.0 to 5 mg per day; for parenteral nutrition a range of 0.15 to 0.8 mg per day is proposed. The manganese content of components of enteral nutrition (EN) and total parenteral nutrition (TPN) solutions is determined using electrothermal atomic absorption spectrometry. Comparison is made between calculated and measured values. The manganese present in supplementary nutrition and flavor stuffs is also measured. The intake of manganese by EN is calculated based on the daily administration, and is found to vary from 192 to 7373 µg per day. In prepared TPN-solutions, the manganese contribution of all components before adding the Oligo Complex is found to be less than 0.2% of the total manganese content. After addition of the Oligo Complex mixture, a mean daily intake of 5.02±0.16 mg per day is found.
