Abstract:Auf die Vitamin-C-Gehalte der Milch verschiedener Haustiere, insbesondere des Rindes, wurde in einer friiheren Arbeit bereits eingegangen [I]. Es sei an dieser Stelle lediglich nochmals darauf hingewiesen, daB der Vitamin-C-Gehalt der Kuhmilch zwischen 0,5 und 3,0 mg/roo g schwanken kann; Durchschnittswerte liegen etwa zwischen 1,5 und 2,o mgjIoo g.I. cber die Haltbarkeit der ~-Ascorbilzsaure in Milch PETERSEW beschreibt in seiner ubersichtsarbeit [z] besonders den EinfluB der Pasteurisierung der Milch auf ih… Show more
“…Deschacht & Hendrickx (1962) claim that their modification of the colorimetric method of Moor (1956) is more reproducible than the 2,6-dichlorphenolindophenol method for measuring ascorbic acid in milk, and Deutsch & Weeks (1965) recommend a microfluorimetric method for measuring the vitamin in fortified milk. The stability of ascorbic acid in milk has been studied by Herrmann & Grossmann (1963). They found that ascorbic acid was oxidized more slowly in milk than in aqueous solution and that even at 100°C the L-ascorbic acid content of milk diminished only slowly.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
