Solubility of Simplesse 100, the only whey-based fat substitute, was found to be good, considering the fact that technology for preparation of Simplesse 100 is a sequence of thermal steps. To characterize this phenomen, gel chromatography on Sephadex G-100, Sephacryl S-1000 and SDS-PAGE were used, supported by high-speed separation, UV studies and(More)
The determination of alpha-amino nitrogen (alpha-AN) is performed via the formation of amino acid copper complexes and subsequent colorimetric estimation of the dissolved copper as copper diethyldithiocarbamate. The continuous colour reaction by means of an auto-analyzer increases the reliability of the measured values (variation coefficient = 1.7%)(More)
