    Notes: Because of the current interest in the potential physiological effects of trans fatty acids and a brief report that microwave cooking causes isomerization of unsaturated fatty acids, we examined the effects of microwave treatments on the fatty acid composition of several food lipids, i.e., chicken fat, beef tallow, bacon fat, rainbow trout, peanut oil, and potato lipids. The data indicate that microwave cooking per se does not change the fatty acid pattern of these lipids nor cause isomerization of the unsaturated fatty acids.

    Notes: Total lipids, phospholipids (PL), free fatty acids, TBA, carbonyl values, fatty acids and amino acid composition of filleted sucker (FS) and mechanically deboned minced sucker (MDMS), were determined. Higher PL concentration (534 mg/100 g versus 370 mg/100 g) and higher carbonyl values (0.89 μmoles/g versus 0.61 μmoles/g) were found in MDMS. There were no significant differences between FS and MDMS in fatty acid composition of total lipid and phospholipids. The protein content and amino acid composition of FS and MDMS were similar.

    Description / Table of Contents: Analytical methods for the quantitative determination of sulfur-containing units in high polymers, especially acrylonitrile copolymers, are described. They are based on the oxygen-flask-combustion followed by volumetric estimation of sulfate with electrochemical end-point detection, or application of x-ray fluorescence analysis. Experimental details and reproducibility values for the 0,1-0,5% S range are given.
    Notes: Analytische Methoden für die quantitative Bestimmung schwefelhaltiger Bausteine von Polymeren, insbesondere Acrylnitrilcopolymeren, werden beschrieben. Diese basieren einmal auf der Verbrennung im Sauerstoffkolben und nachfolgender maßanalytischer Bestimmung des dabei gebildeten Sulfats mit elektrochemischer Endpunktindikation, bzw. auf der Röntgenfluoreszenzanalyse. Einzelheiten der Arbeitsweisen und Reproduzierbarkeitskennwerte für den Bereich 0,1 bis 0,5% S werden angeführt.
