    Notes: Abstract  In earlier studies of the stability of sulphadimidine (SDM) during the preparation of raw fermented sausage, some unknown reaction products were observed which have been further studied. Sausages prepared with SDM, and their corresponding brines were examined for the presence of desamino-SDM (DAS) and 4-hydroxy-desamino-SDM (SOH), as they are possible products of the reaction between SDM and the additive nitrite. After extraction, clean-up and solid-phase extraction (SPE) concentration, the compounds were identified by HPLC followed by diode array detection. The presence of SOH and DAS could be demonstrated in both sausage and brine. In sausage 2.5% of SDM was converted to DAS, while only a minor amount (0.1%) was transformed to SOH. In brine approximately 2.5% and 4% of the original amount of SDM was found as DAS and SOH, respectively.

    Notes: Abstract  Raw fermented sausage was prepared from a dough to which sulphadimidine (SDM), a drug frequently used in animal husbandry, was added. With the aid of thermospray-mass spectroscopy further evidence was obtained that, during preparation, reactions with nitrite added to the dough resulted in the formation of desamino-SDM and 4-hydroxydesamino-SDM. An indication was obtained that traces of chlorodesamino-SDM were present in the brine, but this observation could not be established.

    Description / Table of Contents: Abstract The transformation of sulphadimidine (SDM) during raw fermented suasage preparation was studied to elucidate the SDM decrease found in an earlier study. The raw fermented sausages were prepared from batters containing 1 and 10 mg [14C]-SCM kg−1. The sausages and the brines were analysed using methods based on solid-phase extraction followed by HPLC combined with liquid scintillation counting. It can be concluded that the decrease in SDM level is mainly caused by (i) leaching into the brine (approx. 25%), (ii) transformation of SDM, possibly by reactions with components in the sausage or the brine, as the presence of five reaction products from SDM could be demonstrated, and (iii) formation of bound residues (approx. 20%).
    Notes: Zusammenfassung Die Transformation von Sulfadimidin (SDM) während der Rohwurstherstellung wurde untersucht um die bei vorhergehenden Untersuchungen gefundene SDM-Abnahme zu klären. Die Rohwurst wurde mit 1 und 10 mg14C-SDM pro kg bereitet. Die Analyse der Wurst und Pökellake erfolgte Fest-Flüssig-Extraktion und HPLC, kombiniert mit Flüssigkeits-Szintillation-Zählung. Die Abnahme des SDM-Gehaltes in der Wurst wurde hauptsächlich verursacht durch: Auslaugen (ungefähr 25%), Reaktionen von SDM mit Komponenten in der Wurst und in der Lake (fünf Reaktionsprodukte wurden gefunden), und Bildung von gebundenen Rückständen (ungefähr 20%).

    Notes: Abstract  The presence of an adduct of sulphadimidine with glucose, i.e. N4-glucopyranosyl-sulphadimidine, was demonstrated in raw fermented sausage and batter to which sulphadimidine was added. Identification was performed by HPLC followed by diode array detection. This study demonstrates the need for a hydrolysis step prior to the determination of sulphadimidine for inspection purposes, in food samples containing glucose.
